Migraines and Eye Health

by ArticlesBlog

Understanding the Connection and How to Find Relief

If you’ve ever experienced a migraine, you know it’s much more than just a headache. Migraines can cause severe, throbbing pain along with nausea, sensitivity to light and sound, and even temporary vision disturbances. For many people, the first signs of a migraine actually involve the eyes.

Understanding how migraines affect your vision, recognizing potential triggers, and knowing when to seek professional care can help you better manage these episodes and protect your overall eye health.

What Is a Migraine?

A migraine is a neurological condition that affects millions of people each year. While many migraines involve intense head pain, they can also produce a variety of visual and sensory symptoms that often begin before the headache itself.

Some individuals experience migraines only occasionally, while others may have them several times a month.

How Do Migraines Affect Your Eyes?

Many migraine sufferers experience visual symptoms known as an ocular aura or visual aura. These symptoms are temporary and usually last between 5 and 60 minutes before the headache begins, although some people experience the visual symptoms without developing a headache.

Common visual symptoms include:

  • Flashing lights
  • Zigzag or wavy lines
  • Blind spots
  • Blurred vision
  • Temporary loss of part of your visual field
  • Difficulty focusing
  • Light sensitivity (photophobia)

These visual disturbances occur because of temporary changes in brain activity that affect the visual cortex—not because of damage to the eyes themselves.

What Causes Migraines?

The exact cause of migraines isn’t fully understood, but researchers believe they result from complex interactions between the brain, nerves, and blood vessels. Genetics also plays an important role, as migraines often run in families.

Several common triggers may increase the likelihood of a migraine, including:

  • Stress and anxiety
  • Lack of sleep
  • Hormonal changes
  • Dehydration
  • Skipping meals
  • Bright sunlight
  • Strong odors
  • Certain foods and beverages
  • Weather changes
  • Prolonged screen time
  • Eye strain

Because triggers vary from person to person, keeping a migraine diary can help identify patterns.

Can Extreme Heat Trigger a Migraine?

Yes. For many people, extreme heat can be a significant migraine trigger.

Hot weather can contribute to migraines in several ways:

  • Dehydration Even mild dehydration reduces blood volume and may affect blood flow to the brain, increasing the likelihood of a migraine.
  • Bright Sunlight Intense sunlight and glare can trigger migraines in individuals who are sensitive to light.
  • High Humidity Heat combined with humidity places additional stress on the body and may contribute to headaches and migraines.
  • Physical Exertion Outdoor activities during periods of extreme heat can increase body temperature and dehydration, making migraines more likely.
  • Changes in Barometric Pressure Many migraine sufferers are sensitive to weather changes, particularly when storms or heat fronts move through an area.

Is Eye Strain Causing Your Headaches?

Not every headache is a migraine. In some cases, uncorrected vision problems or digital eye strain can cause headaches that mimic migraine symptoms.

You may experience headaches if you have:

  • An outdated eyeglass prescription
  • Uncorrected astigmatism
  • Difficulty focusing
  • Eye muscle imbalance
  • Excessive computer or smartphone use

A comprehensive eye examination with the doctors at Bissell Eye Care can determine whether a vision problem is contributing to your headaches.

How Are Migraines Treated?

Migraine treatment depends on the severity and frequency of attacks. Your primary care physician or neurologist may recommend:

  • Over-the-counter pain relievers
  • Prescription migraine medications
  • Preventive medications for frequent migraines
  • Lifestyle modifications
  • Stress management techniques

The doctors at Bissell Eye Care may also recommend ways to reduce visual triggers, such as updated prescription lenses or specialty lenses designed to reduce glare and light sensitivity.

Tips to Help Prevent Heat-Related Migraines

While not every migraine can be prevented, these healthy habits may reduce your risk during the summer months:

  • Stay well hydrated throughout the day.
  • Wear sunglasses that block 100% of UVA and UVB rays.
  • Wear a wide-brimmed hat when outdoors.
  • Avoid prolonged exposure to extreme heat.
  • Take frequent breaks in air-conditioned environments.
  • Eat regular meals and avoid skipping food.
  • Get adequate sleep each night.
  • Limit screen time and follow the 20-20-20 rule to reduce eye strain.
  • Identify and avoid your personal migraine triggers whenever possible.

When Should You See an Eye Doctor?

Although migraines often involve visual symptoms, it’s important not to assume every vision change is migraine-related.

Schedule an eye examination if you experience:

  • Frequent headaches associated with vision changes
  • Blurred vision that does not improve
  • New floaters or flashes of light
  • Double vision
  • Eye pain
  • Difficulty focusing
  • Changes in your eyeglass prescription

If you suddenly lose vision in one or both eyes, develop a severe headache unlike any you’ve had before, or experience weakness, numbness, confusion, or difficulty speaking, seek emergency medical care immediately. These symptoms may indicate a more serious medical condition, such as a stroke.

The Importance of Comprehensive Eye Care

Because many migraine symptoms involve the eyes, regular comprehensive eye examinations are an important part of maintaining your overall health. An eye exam can identify vision problems that may contribute to headaches and help rule out eye diseases that can produce similar symptoms.

If migraines or recurring headaches are affecting your daily life, don’t ignore them. Working with both the doctors at Bissell Eye Care and your primary healthcare provider can help identify potential triggers, improve your comfort, and protect your vision.

Healthy eyes and healthy habits go hand in hand. By staying hydrated, protecting your eyes from bright sunlight, reducing eye strain, and receiving regular eye exams, you can take important steps toward minimizing migraine triggers and enjoying clearer, more comfortable vision.

Protect Your Eyes from Summer Heat

by ArticlesBlog

Summer is a wonderful time to enjoy the outdoors, but when temperatures soar into the 90s and beyond, the extreme heat can take a toll on more than just your body—it can also affect your eyes. Heat, intense sunlight, dry air, and increased exposure to wind can all contribute to eye discomfort, especially for those who already suffer from dry eye disease.

Understanding how hot weather impacts your eyes and taking simple preventive measures can help keep your vision healthy and comfortable all summer long.

Why Does Extreme Heat Affect Your Eyes?

Your eyes are protected by a thin layer of tears called the tear film. This essential layer keeps the eyes lubricated, washes away debris, delivers nutrients to the cornea, and provides clear vision.

During periods of extreme heat, the tear film can evaporate more quickly, leading to symptoms of dry eye. Several summer conditions contribute to this problem:

  • High temperatures accelerate tear evaporation.
  • Air conditioning removes moisture from indoor air.
  • Fans create constant airflow that dries the eyes.
  • Sun exposure and UV rays can irritate the eye’s surface.
  • Wind from driving, boating, or outdoor activities increases tear evaporation.
  • Dehydration reduces your body’s ability to produce healthy tears.

 Signs Your Eyes May Be Dry

If your tear film becomes unstable, you may experience:

  • Burning or stinging sensations
  • Redness
  • Itchy eyes
  • Blurred vision that improves with blinking
  • Watery eyes (yes, excessive tearing can actually be a sign of dry eyes!)
  • A gritty or sandy feeling
  • Sensitivity to light
  • Eye fatigue, especially when reading or using digital devices

If these symptoms persist, it’s important to schedule a comprehensive eye examination.

How to Protect Your Tear Film During Extreme Heat

Fortunately, there are several simple steps you can take to help preserve your tear film and keep your eyes comfortable.

  • Stay Hydrated Your eyes depend on proper hydration to produce healthy tears. Drink plenty of water throughout the day, especially if you’re spending time outdoors or exercising in hot weather.
  • Wear Quality Sunglasses Choose sunglasses that block 100% of UVA and UVB rays. Wraparound styles offer additional protection by reducing wind exposure and limiting tear evaporation.
  • Use Artificial Tears Over-the-counter lubricating eye drops can replenish moisture and provide relief. Preservative-free artificial tears are often recommended if you use them several times a day.
  • Avoid Eye Drops marketed as “redness relievers,” as frequent use may actually worsen irritation.
  • Limit Direct Airflow Avoid sitting directly in front of fans, car vents, or air conditioners whenever possible. Constant airflow can quickly dry out the surface of your eyes.
  • Wear Protective Eyewear Outdoors Whether you’re mowing the lawn, gardening, cycling, or enjoying water sports, protective eyewear shields your eyes from dust, pollen, wind, and debris that can further irritate dry eyes.

When Dry Eyes May Be More Than Summer Irritation

While many people notice occasional dryness during hot weather, chronic dry eye disease can have underlying causes such as:

  • Aging
  • Hormonal changes
  • Certain medications
  • Autoimmune diseases
  • Meibomian gland dysfunction
  • Contact lens wear
  • Previous eye surgery

If your symptoms continue despite using artificial tears or become increasingly bothersome, the doctors at Bissell Eye Care can evaluate the cause and recommend advanced treatment options.

Don’t Ignore Persistent Eye Discomfort

Dry eye is more than an inconvenience. Left untreated, chronic dryness can damage the surface of the eye, increase the risk of infection, and interfere with your daily activities and quality of life.

A comprehensive eye examination can determine whether your symptoms are caused by environmental factors or an underlying eye condition. Today’s dry eye treatments are more effective than ever and can be tailored to your individual needs.

Keep Your Eyes Comfortable All Summer Long

Extreme heat doesn’t have to mean uncomfortable eyes. Staying hydrated, protecting your eyes from the sun and wind, maintaining a healthy tear film, and seeking professional care when symptoms persist can help you enjoy everything summer has to offer.

If you’re experiencing burning, irritation, blurred vision, or persistent dry eyes, schedule an appointment by calling 724-443-6767 or 7247-226-0444. We’ll evaluate your eye health and recommend the best treatment plan to keep your eyes healthy, comfortable, and seeing clearly throughout the summer.

Fireworks Eye Safety: Protect Your Vision This Summer

by ArticlesBlog

Summer celebrations often include fireworks, but they also bring a significant risk of injury—especially to the eyes. While fireworks can be beautiful and exciting, they can cause serious and sometimes permanent vision damage in just seconds.

According to the US Consumer Product Safety Commission, thousands of people are treated in emergency rooms each year for fireworks-related injuries, with many incidents occurring during the weeks surrounding Independence Day. “Adults ages 25 to 44 accounted for the largest share of reported injuries (32%), followed by people ages 15 to 24 (24%). The most frequently injured body parts were hands and fingers (36%) and head, face, and ears (22%). Burns were the most common injury, making up 37% of all emergency room visits.”

Common Firework-Related Eye Injuries

Fireworks can cause:

  • Burns to the eyelids and surrounding tissue
  • Corneal abrasions (scratches on the eye)
  • Retinal damage
  • Chemical injuries from explosive materials
  • Penetrating injuries that can lead to permanent vision loss

 

Even bystanders who are not handling fireworks can be injured by flying debris, sparks, or malfunctioning devices.

Sparklers Are Not as Safe as They Seem

Many parents consider sparklers a safer alternative, but they can be extremely dangerous. Sparklers burn at temperatures of approximately 2,000 degrees Fahrenheit—hot enough to melt some metals. They can quickly ignite clothing and cause severe burns to the hands, face, and eyes.

The National Fire Protection Association reports that sparklers account for a significant percentage of fireworks-related injuries each year, particularly among young children. For safer celebrations, consider alternatives such as glow sticks, LED light wands, confetti poppers, or colored streamers.

Fireworks Safety Tips

To reduce the risk of eye injuries:

  • Attend professional fireworks displays whenever possible.
  • Stay at least 500 feet away from launched fireworks.
  • Never allow children to handle fireworks, including sparklers.
  • Wear protective safety glasses if lighting fireworks.
  • Keep spectators at a safe distance.
  • Never hold fireworks in your hand when lighting them.
  • Do not point or throw fireworks at another person.
  • Keep a bucket of water or garden hose nearby.

If fireworks fail to ignite, do not attempt to relight it. Leave it alone and follow local disposal guidelines. Never touch or handle unexploded fireworks.

What To Do If an Eye Injury Occurs

A fireworks-related eye injury should always be treated as a medical emergency. Immediate care can help preserve vision.

If an eye injury occurs:

DO:

  • Seek emergency medical attention immediately.
  • Protect the eye with a loose shield if possible.
  • Keep the injured person calm and avoid further movement.

DO NOT:

  • Rub the eye.
  • Rinse the eye with water.
  • Apply pressure to the eye.
  • Remove any object stuck in the eye.
  • Use eye drops or ointments unless directed by a physician.
  • Take aspirin or other blood-thinning medications unless advised by a healthcare professional.

Enjoy a Safe and Happy Fourth of July

Fireworks can create lasting memories—but they can also cause life-changing injuries. By following proper safety precautions and leaving fireworks to trained professionals whenever possible, you can help protect your family’s vision and overall health.

If you experience an eye injury or have concerns about your eye health, contact Bissell Eye Care immediately at (724) 444-6767 or (724) 226-0444.

From all of us at Bissell Eye Care, we wish you and your family a safe, enjoyable summer and a happy Independence Day. We also extend our gratitude to the veterans and active-duty service members whose sacrifices help preserve our freedoms.

Understanding Cataracts and Today’s Advanced Treatment Options

by ArticlesBlog

June is Cataract Awareness Month, making it the perfect time to learn about one of the most common causes of vision loss. Cataracts affect millions of Americans each year and are a natural part of the aging process. In fact, by age 80, more than half of all Americans either have a cataract or have undergone cataract surgery.

What Is a Cataract?

A cataract occurs when the eye’s natural lens becomes cloudy, preventing light from passing clearly through to the retina. Many patients describe their vision as looking through a foggy, frosted, or dirty window.

Common symptoms of cataracts include:

  • Blurry or cloudy vision
  • Increased sensitivity to light and glare
  • Halos around headlights or lamps
  • Difficulty driving at night
  • Faded or yellowed colors
  • Frequent changes in eyeglass prescriptions
  • Double vision in one eye

Because cataracts usually develop slowly, many people may not notice changes in their vision until the cataract has significantly progressed.

Who Is at Risk?

While aging is the most common cause of cataracts, other factors can increase your risk, including:

  • Diabetes
  • Smoking
  • Excessive alcohol consumption
  • Prolonged exposure to ultraviolet (UV) light
  • Long-term steroid use
  • Previous eye injuries or surgeries
  • Family history of cataracts

Types of Cataracts

Although age-related cataracts are the most common, several other types exist:

Secondary Cataracts

These may develop following eye surgery or as a result of medical conditions such as diabetes. A “secondary cataract” can also refer to clouding that develops behind an implanted lens after cataract surgery, which is easily treated with a quick laser procedure.

Traumatic Cataracts

These cataracts occur following an eye injury and may develop immediately or even years later.

Congenital Cataracts

Some children are born with cataracts or develop them during childhood. Depending on their severity, treatment may be necessary to prevent vision problems.

Radiation Cataracts

Exposure to certain types of radiation can increase the risk of cataract formation.

Cataract Surgery: One of the Safest and Most Successful Procedures

The only effective treatment for cataracts is surgery. Fortunately, cataract surgery is one of the most commonly performed and successful procedures in medicine, with millions of surgeries performed each year in the United States.

During the procedure, the cloudy natural lens is removed and replaced with a clear artificial lens called an intraocular lens (IOL). The surgery typically takes less than 30 minutes, is performed on an outpatient basis, and most patients notice improved vision within a few days.

New Advances in Cataract Treatment

Today’s cataract surgery offers more than simply removing a cloudy lens. Modern technology allows surgeons to customize vision correction based on each patient’s lifestyle and visual needs.

Premium Intraocular Lenses (IOLs)

Patients now have several lens options beyond traditional monofocal lenses:

  • Monofocal Lenses: Provide excellent distance vision but usually require glasses for reading.
  • Toric Lenses: Correct cataracts and astigmatism simultaneously.
  • Multifocal Lenses: Offer vision at multiple distances, reducing dependence on glasses.
  • Extended Depth of Focus (EDOF) Lenses: Provide a continuous range of vision with fewer visual disturbances than some multifocal lenses.

Laser-Assisted Cataract Surgery

Some surgeons offer laser-assisted cataract surgery, which uses advanced laser technology to perform portions of the procedure with exceptional precision. While traditional cataract surgery remains highly effective, laser-assisted techniques may provide additional accuracy for select patients.

Lifestyle-Based Vision Planning

Today’s cataract evaluations often include advanced imaging and measurements that allow surgeons to tailor treatment based on a patient’s daily activities, hobbies, occupation, and desire for reduced dependence on glasses.

Protecting Your Vision

Although cataracts cannot always be prevented, you can help protect your eye health by:

  • Wearing UV-protective sunglasses outdoors
  • Managing diabetes and other chronic conditions
  • Avoiding smoking
  • Eating a healthy diet rich in fruits and vegetables
  • Scheduling regular comprehensive eye exams

The Importance of Annual Eye Exams

Many cataracts can be detected long before they significantly affect vision. Comprehensive eye exams, including dilation when appropriate, allow your eye doctor to monitor cataracts and screen for other serious eye diseases such as glaucoma, macular degeneration, and diabetic eye disease.

If you’ve noticed blurry vision, increased glare, difficulty driving at night, or changes in your eyesight, it may be time for an evaluation.

Call Bissell Eye Care today at 724-444-6767 or 724-226-0444 to schedule your comprehensive eye exam and learn about the latest options available to help you maintain clear, healthy vision.

New Technology in Bifocal Contact Lenses

by ArticlesBlog

Bifocal contact lenses have been around for years, but over the course of time they’ve come a long way. Thanks to advances in technology, today’s options are more comfortable, more effective, and available in a wider variety of designs than ever before. If one type or brand doesn’t work for you, there’s a good chance another will.

As of early 2026, new bifocal/multifocal contact lens technology focuses on enhancing comfort for presbyopia through advanced water-gradient materials, daily disposable options, and customized, stable designs. Key innovations include “celligent” technology for enhanced surface hydration, “digital boost” features for screen time, and expanded, stable Toric multifocal options.

Around age 40, many people begin to notice changes in their near vision due to presbyopia—a natural condition that makes it harder to focus on close objects. You might find yourself holding menus, books, or your phone farther away to read clearly, or relying on reading glasses or bifocals. For those with active lifestyles, bifocal and multifocal contact lenses offer a convenient alternative—no extra pair of glasses needed.

There are several types of contact lenses designed to address both near and distance vision:

Concentric Multifocal Lenses
These lenses feature a center zone for distance vision, surrounded by rings that alternate between near and distance prescriptions.

Aspheric Multifocal Lenses
Similar to progressive eyeglasses, these lenses provide a smooth, gradual transition from distance to near vision without visible lines. They rely on your brain’s ability to adapt and select the correct focus depending on where you’re looking.

When choosing the right lens, factors like your pupil size and near vision prescription (called your “add”) are important. In general, aspheric lenses tend to work well for mild to moderate presbyopia, while concentric or segmented designs may be better for more advanced cases.

Bifocal vs. Multifocal Contacts—What’s the Difference?

  • Bifocal contact lenses contain two distinct prescriptions—one for distance and one for near vision. Some designs, called segmented or translating bifocals, position the near prescription in the lower portion of the lens, similar to bifocal glasses.
  • Multifocal contact lenses offer a range of powers within the same lens and typically work in one of two ways:
    • Simultaneous Vision: Your eye looks through both near and distance zones at once, and your brain selects the appropriate focus.
    • Alternating Vision: The lens shifts slightly as your eye moves, allowing you to look through different zones for near or distance vision.

Today’s lenses are available in soft, rigid gas permeable, and hybrid materials. Many options also offer flexible replacement schedules, including daily disposables for added convenience and hygiene.

If you’ve struggled with bifocal contacts in the past—or thought they weren’t an option for you—it may be time to try again. Modern designs have made them more accessible and effective for a wider range of patients.

Ready to simplify your vision and enjoy activities like reading, gardening, or sports without switching glasses? Contact Bissell Eye Care at 724-443-6767 or 724-226-0444 to learn how today’s bifocal and multifocal contact lenses can work for you.

When Floaters Are More Than Just Annoying

by ArticlesBlog

Have you ever noticed small spots, threads, or cobweb-like shapes drifting across your vision—especially when looking at a bright sky or a white screen? These are called eye floaters, and they’re a very common visual experience.

What Are Eye Floaters?

Floaters may look like tiny dots, squiggly lines, or shadowy shapes that seem to move as your eyes move. They often drift away when you try to focus directly on them. While they may appear to be in front of your eye, they’re actually inside it.

Floaters are shadows cast on the retina—the light-sensitive layer at the back of your eye that processes what you see.

Why Do Floaters Happen?

Inside your eye is a gel-like substance called the vitreous humor, which fills the space between the lens and the retina. Over time, this gel naturally begins to shrink and change consistency.

As it does, tiny clumps, strands, or pockets can form within the vitreous. When light passes through the eye, these irregularities block or scatter the light, casting small shadows on the retina—what you perceive as floaters.

Common Causes and Risk Factors

Floaters are often a normal part of aging, but certain factors can make them more noticeable or more likely to occur:

  • Aging (especially after age 50)
  • Nearsightedness (myopia)
  • Cataract surgery
  • Eye inflammation (uveitis)
  • Previous eye injuries
  • YAG laser procedures after cataract surgery

Many people over 60 experience floaters, and they often become less noticeable over time as the brain adapts and learns to ignore them.

When Should You Seek Treatment?

Most floaters are harmless and don’t require treatment. However, some symptoms can signal a more serious condition and should be evaluated immediately by an eye care professional:

  • A sudden increase in the number of floaters
  • Flashes of light in your vision
  • A dark curtain or shadow moving across your field of vision
  • Sudden loss of peripheral (side) vision

These symptoms could indicate a retinal tear or detachment, which requires urgent care to prevent vision loss.

Take Care of Your Vision

Even if your floaters seem minor, it’s important to mention any changes in your vision during your regular eye exams. Monitoring your eye health helps ensure that any potential issues are caught early.

If you notice new floaters or changes in your vision, the team at Bissell Eye Care is here to help evaluate your symptoms and provide guidance.

In the meantime, don’t forget your sunglasses and enjoy time outdoors—just keep an eye on any changes in your vision. For more information contact one of our offices at 724-443-6767 or 724-226-0444.

Women’s Eye Health Month: Why Women Are at Greater Risk for Vision Problems

by ArticlesBlog

April is National Women’s Eye Health and Safety Month, a time dedicated to raising awareness about the unique vision challenges women face. Did you know that two out of every three people living with blindness or vision problems are women? This makes prioritizing eye health especially important.

Women are at a higher risk for sight-threatening eye diseases, as well as vision changes linked to hormonal shifts throughout life—including puberty, pregnancy, and menopause.

Why Women Are More Vulnerable to Eye Conditions

Hormonal fluctuations—especially changes in estrogen—can significantly impact eye health.

During Puberty
Increased estrogen levels can affect the shape and structure of the eye, potentially leading to nearsightedness or farsightedness. These changes may also increase the risk of conditions like dry eye syndrome or keratoconus.

During Pregnancy
Hormonal changes can temporarily affect the cornea, lens, and retina. Many women experience blurred vision, light sensitivity, or difficulty seeing at night. Pregnancy can also increase the risk of conditions like gestational diabetes, which may impact eye health.

During Menopause
A drop in estrogen levels can lead to dry eye syndrome, causing discomfort, blurred vision, and even damage to the eye’s surface. Additionally, the risk for age-related conditions such as cataracts and macular degeneration increases after menopause.

Because of these life-stage changes, regular comprehensive eye exams are essential for early detection and treatment.

Tips to Maintain Optimal Eye Health

  • Wear UV protection: Choose sunglasses that block 100% of UV rays and consider a wide-brimmed hat for added protection.
  • Eat for your eyes: Include leafy greens, colorful fruits, and omega-3-rich foods like salmon and flaxseed.
  • Quit smoking: Smoking increases the risk of cataracts, macular degeneration, and other serious eye conditions.
  • Limit screen strain: Take regular breaks from digital devices, blink often, and use artificial tears if needed.
  • Practice good hygiene: Wash your hands before touching your eyes and avoid sharing makeup or brushes.
  • Manage health conditions: Keep conditions like diabetes and high blood pressure under control to protect your vision.

Take Charge of Your Eye Health

Women’s Eye Health Month is a reminder to make your vision a priority. With women making up the majority of those affected by vision loss, proactive care is key. Your eyes are precious—take care of them!

Schedule your comprehensive eye exam today to protect your sight for years to come. Call our office at 724-443-6767 or 724-226-0444 to get started.

How People with Low Vision Can Use a Computer More Comfortably

by ArticlesBlog

Using a computer can feel challenging for individuals with low vision—but with today’s technology and simple adjustments, it’s more accessible than ever. From built-in tools to helpful accessories, there are many ways to make digital screens easier to see and navigate.

Screen Readers: Let Your Computer Talk to You

For those with tunnel vision or central vision loss, reading an entire screen can be tiring. Screen-reading programs provide a helpful solution by reading text, icons, and menus aloud in a synthetic voice. Some even announce cursor location.

Many modern computers come with built-in screen readers, and additional programs can be installed if needed. Some tools also allow you to highlight specific text, so only what you want is read aloud.

Increase Text and Screen Size

Small text and icons can be a major barrier for low-vision users. Fortunately, you can easily enlarge them:

  • On a PC: Hold Ctrl + “+”
  • On a Mac: Hold Command + “+”
  • Use your browser’s zoom feature
  • Install magnification software to enlarge everything on your screen, including the cursor and icons

These adjustments can make a big difference in readability and comfort.

Choose a Low Vision-Friendly Mouse

Clicking small icons can be difficult, which is why some people prefer keyboard shortcuts.

However, if you use a mouse:

  • Opt for an ergonomic design for better control
  • Consider a wireless mouse for easier movement
  • Adjust the cursor speed so it’s easier to track on screen

Small changes like these can improve accuracy and reduce frustration.

Reduce Glare and Improve Contrast

Glare can make screens harder to see, especially for those with vision impairment. To reduce it:

  • Position your screen away from windows
  • Use blinds or curtains to control light
  • Tilt your monitor to minimize reflections
  • Consider an anti-glare screen or hood

Increasing your screen’s contrast settings can also make text and images appear sharper and easier to distinguish.

Upgrade Your Monitor

Older monitors can flicker and contribute to digital eye strain. Switching to a modern flat-panel display can provide a clearer, more stable image.

For best results, choose a monitor that’s at least 21 inches to allow for larger, more comfortable viewing.

Back-to-School Eye Exams: An Important Step for Academic Success

by ArticlesBlog

As the school year begins, many parents focus on gathering school supplies, organizing schedules, and preparing their children for the classroom. But there’s one essential item that’s often overlooked—an annual eye exam. Good vision is foundational to a child’s ability to learn, and yet vision issues can often go unnoticed, especially by children themselves.

 

Why Eye Exams Matter More Than You Think

Did you know that 80% of what children learn in school is presented visually? From reading and writing to using digital devices and viewing the board, clear vision is essential. However, vision screenings done at school or pediatric offices are not comprehensive. They may miss issues like eye teaming, focusing problems, or even moderate refractive errors such as nearsightedness, farsightedness, and astigmatism.

How Vision Problems Impact Learning

Children with undiagnosed vision issues may struggle to focus, avoid reading, or fall behind academically. In fact, many symptoms of vision problems can be mistaken for behavioral issues, such as ADHD or lack of interest. Common signs to watch for include:

  • Frequent squinting or tilting the head
  • Holding books or screens very close
  • Complaints about headaches or tired eyes
  • Difficulty paying attention in class
  • Poor reading comprehension or slow reading pace
  • Excessive eye rubbing
  • Eye Strain and Digital Learning

With the growing use of tablets and computers in schools, children are spending more time than ever in front of screens. This can lead to digital eye strain, also known as computer vision syndrome. Symptoms may include:

  • Blurred or double vision
  • Eye fatigue
  • Dry or irritated eyes
  • Difficulty refocusing from screen to distance

Annual eye exams can help identify and manage these issues early, ensuring your child is visually prepared for the demands of today’s learning environment.

When Should Children Have Their Eyes Examined?

The American Optometric Association recommends the following schedule:

  • First exam at 6 months
  • Second exam at age 3
  • Before starting kindergarten
  • Annually thereafter, or as recommended by your optometrist

Early detection of vision issues can prevent long-term learning difficulties and give your child the best chance for success—both in and out of the classroom.

Set Your Child Up for Success

As you prepare for the school year ahead, make sure an eye exam is on your checklist. A simple visit to your optometrist can make a world of difference in your child’s academic performance, confidence, and comfort.

Book your child’s back-to-school eye exam today—and help them start the year off seeing clearly and learning confidently.  Call 724-443-6767 or 724-226-0444 to schedule your child’s appointment.

Managing Light Sensitivity with Stargardt Disease This Summer

by ArticlesBlog

Summer’s long, sunny days are something many look forward to—but if you’re living with Stargardt disease, this season can bring increased challenges. Bright sunlight and glare can significantly impact your comfort and ability to see clearly, making everyday activities more difficult.

At Dr. Bissell’s low vision clinic, he understands how overwhelming bright light can be for individuals with Stargardt disease. That’s why he offers personalized solutions to help you manage light sensitivity and maintain your independence.

As a proud member of the International Academy of Low Vision Specialists (IALVS), we believe that vision loss doesn’t have to limit your lifestyle—even during the sunniest time of year.

Why Stargardt Disease Makes Summer More Difficult

Stargardt disease affects the macula, the part of the eye responsible for sharp central vision. Over time, it can cause bright light to feel uncomfortable and reduce your ability to see detail—especially in high-glare environments like beaches, pavement, or water.

You may notice yourself squinting more often, avoiding time outdoors, or feeling frustrated by reflective surfaces. Our goal is to help you make the most of your remaining vision and feel more comfortable—even in harsh sunlight.

Solutions for Seeing Better in Bright Conditions

Our practice takes a personalized approach to low vision care. After understanding your specific needs and daily challenges, we may recommend:

  • Custom-tinted low vision glasses to reduce glare and enhance contrast
  • UV-protective lenses for added comfort and eye protection outdoors
  • Wraparound frames or side shields to block peripheral light
  • Wide-brimmed hats or visors for additional sun protection
  • Adjusting outdoor activities to early morning or late afternoon when the sun is lower

We’ll also help you improve indoor lighting so you can reduce eye strain even as daylight hours extend.

You Can Enjoy Summer Again

If vision loss is affecting your quality of life, you’re not alone—and you don’t have to navigate it without support. Contact Dr. Bissell today at 724-443-6767 or 724-226-0444 to explore individualized low vision solutions. With the right guidance and devices, you can feel more comfortable in bright conditions and return to the summer activities you enjoy most.
