Summer with Low Vision: Travel Smart, Stay Safe in the Sun & Keep Moving

by ArticlesBlog

Do you have summer vacation plans coming up? Summer is right around the corner and with it comes the chance to get outside, visit new places, and spend quality time with family and friends. If you’re living with low vision, you might face some extra hurdles, but that doesn’t mean you have to sit this season out. With the right tools and expert support, you can enjoy an active, independent summer.

Dr. Bissell has undergone additional training through the International Academy of Low Vision Specialists (IALVS). This elite group of optometrists is specially trained to assess, fit, and adjust low vision aids. Low vision patients who work with Dr. Bissell can receive low vision support that can help you get ready to make the most of your travel adventures.

Smart Travel Tips for People with Low Vision

Planning a vacation, family visit, or day trip? Vision loss doesn’t have to slow you down. We can help you travel with more confidence by recommending portable, low vision-friendly tools like E-Scoop® eyewear, digital magnifiers, telescopic glasses, or custom reading aids that make navigating unfamiliar spaces much easier.

Travel Tips for those with Low Vision:

  • Organize travel documents in large print or digital format
  • Look up hotel and transportation accessibility in advance
  • Notify airlines or bus services ahead of time if you need extra assistance

If vision challenges have made travel feel overwhelming, we’re here to help restore your confidence and independence.

Sun Protection That Works for Low Vision

Bright summer days can be tough on the eyes—especially if you have low vision—but UV protection is essential for everyone, regardless of vision status. The sun’s ultraviolet (UV) rays can cause both short-term discomfort and long-term damage to your eyes, increasing the risk of cataracts, macular degeneration, and other vision problems over time.

For individuals with low vision, the brightness and glare of summer light can make it even harder to see clearly outdoors. Dr. Bissell’s low vision services offer custom-tinted eyewear designed to reduce glare, enhance contrast, and protect sensitive eyes from harmful UV exposure. Larger lenses or wraparound styles also provide added protection by blocking light from multiple angles.

Should You Wear UV Protection if You Don’t Have Low Vision?

But even if you don’t have vision loss, UV protection should still be part of your everyday eye care routine. We recommend that all patients:

  • Wear sunglasses with 100% UVA and UVB protection—even on cloudy days
  • Use wide-brimmed hats to reduce direct sun exposure
  • Seek shade during peak sunlight hours (10 a.m. to 4 p.m.)
  • Schedule regular eye exams to monitor eye health and early signs of UV-related damage

The doctors at Bissell Eye Care can help you select the right sun protection—whether you’re looking for everyday sunglasses, custom low vision lenses, or specialty outdoor eyewear. With the right protection, you can stay comfortable, preserve your long-term vision, and make the most of your summer.

Regaining Independence with E-Scoop Eyewear: A Game-Changer for Those with Low Vision

by ArticlesBlog

For individuals living with low vision, everyday tasks like reading a menu, watching TV, or recognizing faces can become daunting challenges. These struggles often lead to frustration, isolation, and a loss of independence. But there’s new hope for those seeking to reclaim their daily lives: E-Scoop® eyewear, a specialized solution designed to improve vision for people with macular degeneration and other low vision conditions.

 

What is E-Scoop® Eyewear?

E-Scoop glasses are uniquely designed to enhance distance vision by combining five optical elements:

  • Specific lens tint to reduce glare and enhance contrast
  • Custom lens thickness to shift the image to a healthier part of the retina
  • Magnification to make images appear larger
  • Base curve to improve light gathering
  • Prism to reposition the image away from the damaged central retina

The result? A sharper, clearer image that improves the wearer’s ability to see and interact with the world around them—often for the first time in years.

Why Specialized Training Matters

E-Scoop glasses are not available through a standard eye exam. Instead, they require precise customization by a doctor trained in low vision rehabilitation. Dr. Bissell has undergone additional training through the International Academy of Low Vision Specialists (IALVS). This elite group of optometrists is specially trained to assess, fit, and adjust low vision aids like E-Scoop glasses for maximum effectiveness.

This expertise ensures that each patient receives a thorough evaluation and a tailored solution that addresses their unique visual challenges—something traditional eyeglasses or even surgery cannot always offer.

The Value of Independence

One of the greatest challenges for individuals with low vision is the gradual erosion of independence. Driving, reading, cooking, shopping, or even watching loved ones’ expressions can become difficult or impossible. E-Scoop eyewear helps bridge that gap. By enhancing visual function, these glasses enable wearers to return to many of the activities they once enjoyed.

Whether it’s navigating the grocery store without assistance or being able to recognize road signs again, the difference E-Scoop glasses make is not just about seeing better—it’s about living better.

A Personalized Approach to Hope

If you or a loved one is living with low vision and has been told “nothing more can be done,” E-Scoop eyewear may offer a new path forward. Schedule a consultation with Dr. Bissell to find out if you’re a candidate for this life-enhancing technology.

Independence is possible. E-Scoop eyewear can help bring your world back into focus. To learn more about low vision services, call our office at 724-443-6767 or 724-226-0444.

Avoid Eye Infections This Spring: Tips for Allergy Sufferers

by ArticlesBlog

The trees are blooming, the grass is turning green, and spring is in the air — literally. While warmer weather and outdoor time can lift your spirits, they can also bring an unwelcome guest: seasonal allergies.

Have your eyes started watering? Is your nose feeling stuffy? If so, you’re not alone. As flowers bloom and pollen levels rise, it’s important to know how to manage allergy symptoms and prevent complications — including eye infections like pink eye.

Allergy Season Is Here — Start Preparing Now

If you typically suffer through spring, now is the time to act. Experts recommend starting allergy medications before symptoms hit. This can reduce your reaction and help you stay ahead of the pollen.

Common allergy symptoms include:

  • Itchy, red, or watery eyes
  • Clear nasal discharge
  • Sneezing
  • Scratchy throat or ears

Unlike viruses that develop gradually, allergy symptoms often come on suddenly — especially on high-pollen days. Try to limit time outdoors when pollen counts are high, keep windows closed, and use air conditioning when possible. And skip hanging laundry outside — pollen can cling to fabrics.

Eye Allergies & Pink Eye: What’s the Connection?

Among the eye-related issues triggered during allergy season, conjunctivitis (commonly called pink eye) is one of the most common. It refers to inflammation of the thin, clear tissue covering the white of the eye and inside the eyelids.

While the tissue is clear, it contains small blood vessels. When irritated or infected, these vessels enlarge, giving the eye a red or pink appearance.

3 Types of Pink Eye

Allergic Conjunctivitis

  • Triggered by allergens like pollen, dust, or pet dander.
  • Not contagious.

Bacterial Conjunctivitis

  • Caused by bacteria entering the eye.
  • Can lead to serious complications if untreated.

Viral Conjunctivitis

  • Caused by viruses similar to the common cold.
  • Highly contagious but typically clears on its own.

Treatment Options

Allergic Pink Eye:

  • Treated with antihistamines or allergy eye drops.
  • Best prevented by starting allergy medications before symptoms begin.

Bacterial Pink Eye:

  • Requires a visit to your optometrist for prescription antibiotic eye drops.
  • Prompt treatment helps prevent complications and spread.

Viral Pink Eye:

  • Usually resolves on its own in a few days.
  • Apply cool compresses to relieve discomfort — but don’t share them with others, as this form is very contagious.

Prevention Tips

Good hygiene can be the key to not sharing Pink Eye with family members. Stay healthy and reduce your risk of eye infections with these simple precautions:

  • Don’t share towels, washcloths, tissues, or eye drops.
  • Avoid rubbing or touching your eyes — especially after coughing or sneezing.
  • Never share contact lenses or contact lens cases.
  • Remove contacts before swimming, hot tubs, or even showering.
  • Wash your hands frequently, especially in schools, daycares, and other public places.

If you have seasonal allergies, talk with your doctor about prevention strategies. If you’re experiencing red, itchy, or irritated eyes — especially if accompanied by discharge or blurred vision — don’t wait it out. Let the doctors at Bissell Eye Care help you get relief and avoid potential complications.

Bifocal Contact Lenses: A Clear Solution for Aging Eyes

by ArticlesBlog

Are you constantly switching between glasses — one pair for distance, another for reading? Maybe you’ve been relying on bifocals for years, or you’ve noticed that you’re starting to hold books, menus, or your phone at arm’s length just to see the text clearly.

If that sounds familiar, it might be time to consider a more flexible solution: bifocal or multifocal contact lenses.

Why Do Patients Choose Bifocal or Multifocal Contacts?

There’s a common perception that as your vision changes with age, your only options are bifocal glasses or reading glasses. But thanks to advancements in contact lens technology, many people now have a better alternative — especially those with active lifestyles who want the freedom of glasses-free vision.

These lenses are designed to help people with presbyopia — a natural, age-related condition that reduces your ability to focus on close-up objects. Presbyopia typically starts to affect people in their 40s or 50s and progresses gradually.

There are two main types of contact lenses for presbyopia:

  • Bifocal Contact Lenses

These lenses contain two distinct prescriptions in each lens — one for distance and one for near vision — much like traditional bifocal glasses. A segmented bifocal design places the reading prescription in the lower part of the lens and the distance vision in the upper portion, mimicking the design of bifocal glasses.

  • Multifocal Contact Lenses

Multifocal lenses offer a more blended visual experience. They contain multiple prescriptions across the lens, allowing your eye to transition naturally between near, intermediate, and far distances.

There are two main design styles:

  • Simultaneous Vision: Your eye views both near and far zones at the same time, and your brain automatically focuses on the appropriate one.
  • Alternating (or Translating) Vision: Similar to bifocal glasses, these lenses move with your eye’s natural motion, allowing you to shift focus as needed.

Materials & Wear Options

Bifocal and multifocal contacts are available in a variety of materials:

  • Soft lenses (comfortable and easy to adapt to)
  • Rigid gas permeable lenses (offer sharper vision for some prescriptions)
  • Hybrid lenses (combine a gas permeable center with a soft outer ring for comfort and clarity)

Many of these lenses are available in daily disposable options, offering convenience and reducing the risk of infection — a great option for those new to contact lenses or who prefer low-maintenance wear.

If you’re tired of juggling glasses or feel like reading glasses are taking over your life, you’re not alone. Many patients who thought they’d never be able to wear contacts have found success — and freedom — with bifocal and multifocal lenses.

At Bissell Eye Care, our doctors will assess your lifestyle, visual needs, and eye health to determine the best option for you. We’ll guide you through the fitting process, help you adjust, and make sure you’re seeing clearly and comfortably.

Modern Lenses

Modern contact lenses have come a long way — and so has your chance to enjoy clear vision at every distance without the hassle of multiple glasses. Whether you’re golfing, working on the computer, or reading bedtime stories to your grandchildren, there’s likely a contact lens solution that fits your needs.

Call us today at 724-443-6767 or 724-226-0444 to schedule a consultation and find out if bifocal or multifocal contact lenses are the right choice for your lifestyle.

Your vision matters — and so does your freedom.

Preschool Registration & Your Child’s Vision: The Importance of a Comprehensive Eye Exam

by ArticlesBlog

Enrolling your child in preschool is an exciting milestone! As you gather school supplies, medical records, and immunization forms, don’t forget an essential step in preparing your child for success – a comprehensive eye exam.

Many parents assume that a quick vision screening at the pediatrician’s office or school is enough to detect vision problems, but these basic tests can miss up to 60% of eye conditions in young children. A comprehensive eye exam with the doctors at Bissell Eye Care will ensure your child has the clear vision and visual skills they need for learning, socializing, and exploring the world around them.

According to the American Optometric Association, “Every experience a preschooler has is an opportunity for growth and development. They use their vision to guide other learning experiences. From ages 2 to 5, a child will be fine-tuning the visual abilities gained during infancy and developing new ones.”

Vision is Crucial for Early Learning

Did you know that 80% of what a child learns is processed through their eyes? Preschoolers rely on their vision for:

  • Recognizing letters, numbers, and shapes
  • Following along in books and recognizing pictures
  • Developing hand-eye coordination for coloring, puzzles, and crafts
  • Interacting with teachers and classmates

Even minor vision issues can affect a child’s ability to learn, focus, and participate in activities, potentially leading to frustration or misdiagnosed learning difficulties.

Undetected Vision Problems Can Affect Development

Children often don’t realize they have vision problems because they assume everyone sees the same way. If an issue goes undiagnosed, it can impact:

  • Depth perception – Difficulty judging distances when playing or climbing
  • Hand-eye coordination – Struggles with catching a ball, stacking blocks, or using scissors
  • Attention span – Avoiding close-up tasks or becoming easily distracted
  • Confidence – Hesitation in participating in group activities due to blurred vision

Common vision problems in preschoolers include:

  • Nearsightedness (myopia) – Difficulty seeing objects far away
  • Farsightedness (hyperopia) – Trouble focusing on close-up activities
  • Astigmatism – Blurred or distorted vision at all distances
  • Amblyopia (lazy eye) – Reduced vision in one eye that can lead to permanent vision loss if untreated
  • Strabismus (crossed eyes) – Eyes that don’t align properly, which can cause double vision and affect depth perception

Early detection is key to successful treatment!

Vision Screenings Are Not a Substitute for a Comprehensive Eye Exam. While pediatricians or schools may perform basic vision screenings, these tests only check for obvious vision issues. They do not assess eye health, focusing ability, or depth perception—all crucial for a child’s development.

A comprehensive eye exam includes:

  • A full eye health evaluation
  • Testing for eye alignment and coordination
  • Checking for refractive errors (nearsightedness, farsightedness, astigmatism)
  • Assessing depth perception and color vision

If your child does need glasses, starting early can help them adjust quickly and avoid unnecessary struggles in school.

When Should Your Child Have Their First Eye Exam?

  • 6-12 months – The first comprehensive eye exam is recommended to ensure normal development.
  • 3-5 years – A preschool eye exam checks for vision problems before starting school.
  • Before Kindergarten – An exam before formal schooling ensures clear vision for learning.

After the preschool years, children should have an eye exam at least once a year, as their vision can change rapidly as they grow.

Now is the perfect time to schedule your child’s comprehensive eye exam. Healthy vision and strong visual skills will help them thrive in the classroom and beyond! Call our offices at 724-443-6767 or 724-226-0744 today to schedule your child’s appointment.

Daylight Saving Time & Your Eyes: How the Time Change Affects Vision and Sleep

by ArticlesBlog

Who doesn’t love longer daylight hours in the spring? Every spring, we move our clocks forward an hour for Daylight Saving Time (DST)—gaining more daylight in the evening but losing an hour of sleep. While this adjustment may seem minor, it can disrupt sleep patterns, impact overall well-being, and even affect your eye health.

If you’ve ever noticed your eyes feeling dry, irritated, or strained after a time change, you’re not alone. The shift in our internal clocks can lead to fatigue, poor focus, and even increased risk for certain eye conditions. Let’s explore how the time change affects your vision and what you can do to keep your eyes healthy.

Disrupted Sleep Leads to Eye Strain & Fatigue

Your eyes need adequate rest to function properly. Losing an hour of sleep can throw off your circadian rhythm, leading to:

  • Tired, strained eyes – Less sleep can cause the eye muscles to fatigue more quickly, making tasks like reading or using digital screens more difficult.
  • Blurred vision – Sleep deprivation can reduce tear production, leading to dryness and fluctuating vision.
  • Increased sensitivity to light – A lack of rest can make your eyes more sensitive to bright screens and sunlight.

Poor Sleep Quality Can Worsen Dry Eye Syndrome

People who already suffer from dry eye syndrome may experience worsening symptoms after the time change. Sleep deprivation can reduce tear production and cause the eyes to feel gritty, red, and irritated. This is especially true for individuals who:

  • Spend long hours in front of screens
  • Wear contact lenses
  • Have a history of dry eye disease

Blue Light Exposure at Night Disrupts Sleep & Eye Health

Many people struggle to adjust to the new time change and may use phones, tablets, or TVs before bed to wind down. However, blue light exposure from these screens can:

  • Suppress melatonin production – Making it harder to fall asleep.
  • Disrupt circadian rhythms – Leading to restless nights and tired eyes in the morning.
  • Increase digital eye strain – Causing discomfort, headaches, and blurred vision.

Increased Risk of Eye-Related Health Issues

Sleep deprivation—even from a one-hour change—can increase the risk of serious eye conditions, including:

  • Glaucoma – Poor sleep is linked to higher intraocular pressure, a major risk factor for glaucoma.
  • Retinal Damage – A lack of rest may reduce oxygen flow to the eyes, leading to long-term issues.
  • Migraines & Light Sensitivity – Poor sleep can trigger migraines, which often come with visual disturbances.

Tips to Protect Your Eyes During the Time Change

  • Adjust Your Sleep Schedule Early – Start going to bed 15-30 minutes earlier a few days before the time change to help your body adjust gradually.
  • Limit Blue Light Exposure Before Bed – Avoid screens at least an hour before bedtime or use blue light-blocking glasses.
  • Practice the 20-20-20 Rule – If you’re experiencing eye strain, take a break every 20 minutes by looking 20 feet away for 20 seconds.
  • Keep Your Eyes Hydrated – Drink plenty of water and use lubricating eye drops if you experience dryness.
  • Wear Sunglasses Outdoors – Protect your eyes from glare and UV rays, especially in the mornings when your eyes may be more sensitive.
  • Create a Sleep-Friendly Environment – Keep your bedroom cool, dark, and quiet to encourage deep, restful sleep.

Daylight Savings Time

Daylight Saving Time may only shift the clock by an hour, but its effects on sleep and vision can last for days or even weeks. By practicing healthy eye habits and prioritizing good sleep hygiene, you can minimize eye strain, dryness, and fatigue during this transition.

If you’re experiencing persistent vision problems, eye discomfort, or difficulty adjusting to the time change, schedule an eye exam. The doctors at Bissell Eye Care can check for underlying issues and recommend solutions to keep your vision sharp and comfortable.

Understanding Age-Related Macular Degeneration and Low Vision

by ArticlesBlog

February marks Age-Related Macular Degeneration (AMD) Awareness Month, an initiative led by Prevent Blindness to educate the public about the risks, symptoms, and treatment options for this leading cause of vision loss. It is also recognized as Low Vision Awareness Month, highlighting the impact of advanced AMD and other conditions that result in significant visual impairment.

What is Age-Related Macular Degeneration (AMD)?

AMD is a worsening eye disease affecting the macula, which enables sharp central vision. This condition makes it difficult to read, recognize faces, or perform detailed tasks.

There are two main types of AMD:

  • Dry AMD – The more common form, characterized by the thinning of the macula and the buildup of drusen (yellow deposits). It develops gradually over time.
  • Wet AMD – A more severe form caused by abnormal blood vessel growth under the retina, leading to sudden vision loss if untreated.

Symptoms of AMD

Early detection is key, as AMD can progress without noticeable symptoms in its early stages. However, as it advances, individuals may experience:

  • Blurred or distorted central vision
  • Difficulty recognizing faces
  • Dark or empty spots in vision
  • Straight lines appearing wavy

If you or a loved one notices any of these symptoms, scheduling an eye exam as soon as possible is crucial.

Risk Factors for AMD

While age is the biggest risk factor (AMD typically affects those over 50), other contributors include:

  • Smoking – One of the most significant preventable risk factors
  • Genetics – A family history of AMD increases risk
  • High Blood Pressure & Cardiovascular Disease – Poor circulation can contribute to macular damage
  • Poor Diet – A lack of antioxidants and omega-3 fatty acids may speed up AMD progression Excessive UV Exposure – Long-term unprotected sun exposure can damage the retina

Early Detection & Treatment Options

While there is no cure for AMD, early detection can help slow its progression. Regular comprehensive eye exams allow doctors to detect early signs and recommend lifestyle changes or treatment options.

  • Nutritional Supplements – The AREDS2 formula (a combination of vitamins C, E, zinc, copper, lutein, and zeaxanthin) can help slow the progression of intermediate AMD.
  • Anti-VEGF Injections – Used to treat wet AMD, these injections help slow abnormal blood vessel growth in the retina.
  • Healthy Lifestyle Choices – A diet rich in leafy greens, fish, and nuts, quitting smoking, and maintaining a healthy weight can help preserve vision.

Support for Those with Advanced Vision Loss

As AMD progresses, it can result in low vision, a condition where everyday tasks become challenging despite corrective lenses. February is also Low Vision Awareness Month, emphasizing the need for adaptive tools and strategies for those living with severe vision impairment.

Dr. Bissell is a member of the International Academy of Low Vision Specialists (IALVS) and specializes in using specially designed telescopic glasses to help individuals with significantly decreased vision due to AMD and other ocular conditions. These advanced devices can improve quality of life by enhancing the remaining vision for reading, driving, and other essential activities.

With early detection and proper management, individuals with AMD can take steps to slow progression and maintain independence. If you or a loved one is at risk for AMD or experiencing vision changes, don’t wait—schedule a comprehensive eye exam today.  For more information about low vision services, including AMD treatment and personalized vision solutions, contact Dr. Bissell at 724-443-6767 or 724-226-0444.

Heart Health & Your Eyes: The Link Between Cardiovascular Health and Vision Problems

by ArticlesBlog

February is designated as American Heart Month to raise awareness about heart disease, the leading cause of death in the United States. Did you know that your heart and eyes are more connected than you might think? While we often associate heart disease with high blood pressure or cholesterol, its effects can also extend to your vision. The eyes are full of tiny, delicate blood vessels that are highly sensitive to changes in blood flow. When your cardiovascular system is not functioning properly, your eyes may show some of the earliest warning signs.

How Heart Health Affects Your Vision

Since your eyes rely on a steady supply of oxygen-rich blood, any issues affecting your circulation can impact your vision. Here are some common cardiovascular-related eye problems:

Hypertensive Retinopathy (High Blood Pressure & Eye Damage)

High blood pressure (hypertension) can cause damage to the retina, the light-sensitive tissue at the back of your eye. Over time, this can lead to:

  • Narrowed or leaking blood vessels
  • Blurred or double vision
  • Vision loss in severe cases

If left untreated, hypertensive retinopathy can increase the risk of serious eye conditions, including retinal detachment or optic nerve damage.

Diabetic Retinopathy (Diabetes & Vision Loss)

Diabetes and heart disease often go hand in hand. High blood sugar levels can damage the small blood vessels in the retina, leading to diabetic retinopathy. Symptoms include:

  • Dark spots or floaters in vision
  • Blurry or fluctuating vision
  • Difficulty seeing at night

Diabetic retinopathy is a leading cause of blindness, making regular eye exams essential for early detection and treatment.

Retinal Artery & Vein Occlusion (Eye Strokes)

Just like the arteries in your heart, the arteries and veins in your eyes can become blocked due to poor circulation or blood clots. This is known as a retinal artery or vein occlusion, sometimes referred to as an “eye stroke.” It can cause:

  • Sudden vision loss or blurriness
  • Dark spots or a shadow in one eye
  • Pain or pressure in the eye

Since these blockages are often linked to high cholesterol, high blood pressure, or heart disease, they may be a warning sign of future cardiovascular problems.

Age-Related Macular Degeneration (AMD) & Heart Disease

AMD is a leading cause of vision loss in older adults and has been linked to cardiovascular disease. Poor circulation and inflammation can contribute to the breakdown of the macula, the part of the retina responsible for sharp, central vision. Risk factors include:

  • High blood pressure
  • High cholesterol
  • Smoking and poor diet

Keeping your heart healthy can also help slow the progression of AMD.

Protecting Your Heart & Eyes

The good news is that many of the lifestyle habits that promote heart health also benefit your eyes. Here are some ways to keep both in top shape:

  • Control Blood Pressure & Cholesterol – Follow your doctor’s advice on managing hypertension and high cholesterol.
  • Eat a Heart-Healthy Diet – Foods rich in omega-3s, antioxidants, and leafy greens support both heart and eye health.
  • Exercise Regularly – Physical activity improves circulation, reducing the risk of eye and heart conditions.
  • Quit Smoking – Smoking damages blood vessels, increasing the risk of vision loss and heart disease.
  • Schedule Regular Comprehensive Eye Exams that include dilation. The doctors at Bissell Eye Care can detect early signs of heart-related eye issues before they cause permanent damage.

Your eyes can reveal a lot about your overall health, including your risk of heart disease. If you’re experiencing any vision changes, especially sudden blurriness, vision loss, or dark spots call our office at 724-443-6767 or 724-226-0444 to schedule an eye exam as soon as possible. By taking care of your heart, you’re also protecting your eyesight for years to come.

What Causes Dry Eyes in Winter?

by ArticlesBlog

Winter creates a unique set of challenges for your eyes that make them feel drier.  The season brings about environmental changes and lifestyle factors that occur during the colder months, often leading to dry eyes in winter. Here’s why:

Dry Indoor Air: As temperatures drop, we rely on heating systems to stay warm. However, heated air often lacks humidity, drying out the natural moisture in your eyes.

Cold, Windy Conditions: When you’re outside, cold winds can strip moisture from your eyes, exacerbating dryness and irritation.

Reduced Blink Rate: During winter, we tend to spend more time indoors on digital devices. Staring at screens can reduce how often we blink, which limits the spread of tears across the eye’s surface.

Environmental Allergens: Dust and pet dander are more prevalent indoors during winter, which can aggravate dry eyes, especially for those prone to allergies.

Seasonal Tear Production Changes: Cold weather may also reduce tear production for some people, leaving their eyes less equipped to stay moist.

Symptoms of Dry Eyes

Dry eye symptoms can range from mild discomfort to more severe irritation. Common symptoms include:

  • A gritty or sandy feeling in your eyes
  • Redness or irritation
  • Excessive tearing (a response to dryness)
  • Blurred vision
  • Sensitivity to light
  • Difficulty wearing contact lenses

How to Alleviate Dry Eye Symptoms in Winter

Fortunately, there are many ways to protect your eyes from winter dryness and relieve symptoms:

Use a Humidifier: Add moisture back into the air at home or work with a humidifier. This can help prevent your eyes from drying out, especially in heated indoor spaces.

Stay Hydrated: Drink plenty of water throughout the day to keep your body—and your eyes—hydrated.

Apply Artificial Tears: Over-the-counter lubricating eye drops can help replenish moisture and relieve discomfort. Look for preservative-free options for frequent use.

Wear Protective Eyewear: When outdoors, wear wraparound sunglasses or goggles to shield your eyes from cold winds and prevent moisture loss.

Take Screen Breaks: Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. This helps maintain a healthy blink rate and prevents eye strain.

Adjust Your Diet: Incorporate omega-3 fatty acids into your diet by eating foods like salmon, walnuts, and flaxseed. These nutrients support tear production and eye health.

Limit Contact Lens Wear: If your dry eyes are severe, consider switching to glasses temporarily or use contact lenses specifically designed for dry eyes.

Avoid Direct Heat Sources: Sitting too close to heaters or fireplaces can dry out your eyes. Position yourself a few feet away and use a humidifier to counteract the dryness.

While mild dry eye symptoms can often be managed at home, you should contact our office if:

  • Your symptoms are severe or worsening.
  • You experience persistent redness, pain, or vision changes.
  • Over-the-counter treatments aren’t providing relief.

If dry eyes persist despite these measures, consult the doctors at Bissell Eye Care. They can assess the severity of your condition and recommend treatments such as prescription eye drops, punctal plugs, or other advanced therapies. Our doctors can help pinpoint the cause of your dry eyes and create a personalized treatment plan to restore comfort and clarity.

Winter weather doesn’t have to mean discomfort for your eyes. With the right preventive measures and treatments, you can keep your eyes hydrated and healthy all season long. If you have questions or concerns, contact our office at 724-443-6767 or 724-226-0444.

Pink Eye 101: Causes, Types, and Seasonal Triggers

by ArticlesBlog

As another season of cold and flu ramps up, another unwelcome visitor often tags along—pink eye, also known as conjunctivitis. Pink eye is a common condition, particularly during colder months, when respiratory illnesses are more prevalent. Let’s take a closer look at what causes pink eye during this time, the different types of conjunctivitis, and how to protect your eyes.

Why Does Cold and Flu Season Lead to More Cases of Pink Eye?

The cold and flu season creates the perfect environment for the spread of viruses and bacteria, which are leading culprits of pink eye. Here’s how it happens:

Respiratory Infections: Viruses like adenovirus, often responsible for colds, can also cause viral conjunctivitis. Sneezing, coughing, or touching your eyes after handling contaminated surfaces spreads the virus quickly.

Weakened Immune System: When your body is busy fighting off a cold or the flu, your immune system may be less effective at protecting your eyes from infection.

Close Contact Indoors: During colder months, people tend to spend more time indoors, increasing close contact and the likelihood of sharing germs.

Types of Conjunctivitis

There are three main types of pink eye, each with distinct causes and symptoms:

Viral Conjunctivitis:

  • Cause: Viruses like adenovirus, often linked to colds.
  • Symptoms: Watery discharge, redness, and irritation in one or both eyes.
  • Contagiousness: Highly contagious and often spreads in schools, workplaces, or households.

Treatment: No specific treatment; symptoms typically resolve within 7-14 days. Use a cold compress and artificial tears to relieve discomfort.

Bacterial Conjunctivitis:

  • Cause: Bacteria such as Staphylococcus or Streptococcus.
  • Symptoms: Thick, yellow, or greenish discharge that may cause eyelids to stick together, redness, and swelling.
  • Contagiousness: Extremely contagious and often spread through direct contact or shared items like towels.

Treatment: Requires antibiotics, either in the form of eye drops or ointments, prescribed by the doctors at Bissell Eye Care or your primary care doctor.

Allergic Conjunctivitis:

  • Cause: Allergens like pollen, pet dander, or dust mites.
  • Symptoms: Itchy, watery eyes, redness, and swelling. Symptoms often occur in both eyes.
  • Contagiousness: Not contagious.

Treatment: Over-the-counter or prescription allergy medications and eye drops can help.

How to Prevent Pink Eye During Cold and Flu Season

There are several steps you can take to reduce your risk of pink eye:

Wash Your Hands Frequently: Use soap and water to wash your hands thoroughly, especially after touching your face, coughing, or sneezing.

Avoid Touching Your Eyes: Try to avoid rubbing your eyes, as this can transfer germs directly to the eye.

Disinfect Common Surfaces: Regularly clean surfaces like doorknobs, keyboards, and smartphones to prevent the spread of bacteria and viruses.

Use Your Own Towels and Makeup: Sharing items like face towels, eye makeup, or contact lens cases can increase the risk of spreading pink eye.

Practice Respiratory Hygiene: Cover your mouth and nose with a tissue or your elbow when you sneeze or cough, and dispose of tissues immediately.

Stay Home If You’re Sick: If you have cold or flu symptoms, staying home can help prevent the spread of germs to others.

While many cases of pink eye resolve on their own, you should see the doctors at Bissell Eye Care if:

  • Your symptoms persist for more than a week.
  • You experience significant pain, blurred vision, or sensitivity to light.
  • You have a weakened immune system or an existing eye condition.

Our doctors can diagnose the type of conjunctivitis you have and recommend the best course of treatment to get you back to feeling—and seeing—your best.

Pink eye may be common during cold and flu season, but with proper hygiene and quick action, you can protect your eyes and reduce the risk of spreading this condition. If you suspect you or your child may have pink eye, don’t hesitate to schedule an appointment by calling 724-443-6767 or 724-226-0444. Healthy eyes are always worth it!
