Halloween Eye Safety Tips: Protecting Your Vision While Having Fun

Halloween is a favorite time of year for kids and adults alike—costumes, candy, and spooky fun. But while you’re picking out the perfect costume, it’s important to keep eye safety in mind. As optometrists, we want families to enjoy the holiday without accidents or eye injuries. Here are some Halloween safety tips for costumes, masks, and decorative contact lenses to help protect your vision this season.

Choose Masks Kids Can See Out Of Clearly

Masks are a popular part of many Halloween costumes, but they can sometimes block vision. Poorly fitted masks may limit peripheral vision, making it harder for kids to see cars, steps, or other trick-or-treaters.

  • Look for masks with large eye openings.
  • Test your child’s mask in a well-lit room before Halloween night.
  • If vision is restricted, consider face paint instead of a full mask.

Avoid Non-Prescription Decorative Contact Lenses

Decorative or “cosmetic” contact lenses—like cat eyes, vampire red, or all-white sclera lenses—may seem like the perfect accessory to a spooky costume. However, non-prescription contact lenses sold without an eye exam can be dangerous.

  • Ill-fitting lenses can cause scratches, infections, or even vision loss.
  • Only purchase costume contact lenses from a licensed eye doctor with a valid prescription.
  • Never share contact lenses, even decorative ones.

If your teen is interested in wearing Halloween contact lenses, schedule an eye exam to ensure they are fitted safely.

Watch Out for Sharp Objects in Costumes

Costume swords, wands, pitchforks, or other props with sharp ends can easily poke an eye if someone trips or bumps into another trick-or-treater. To reduce risk:

  • Choose props made of soft, flexible materials.
  • Avoid overly long items that can drag or swing around.
  • Remind kids not to run while holding costume accessories.

Prevent Trip Hazards in Costumes

Long costumes and flowing capes may look dramatic but can be hazardous. Children may trip and fall, increasing the risk of eye injuries or facial trauma.

  • Hem costumes to ankle length or shorter.
  • Avoid shoes that are too big for walking safely.
  • Make sure costumes are free of dangling parts that could catch on decorations.

Halloween is a time for fun, creativity, and family memories. By following these Halloween eye safety tips, you can keep vision clear and protected while enjoying the holiday.

If you have questions about decorative contact lenses or want to schedule an eye exam before Halloween, our office is here to help. Protecting your vision is no trick—it’s a treat you’ll enjoy for years to come.

Fall-Eye-Safety

Protecting Your Eyes During Fall Clean-Up – Why Safety Glasses Matter

by ArticlesBlog

Autumn is a beautiful season—the air turns crisp, leaves change color, and neighborhoods come alive with fall activities. But for many homeowners, fall also means yard clean-up: raking leaves, trimming branches, clearing gutters, and preparing the yard for winter. While it may feel like routine outdoor work, these chores can put your eyes at risk if you’re not careful.

As optometrists, we want to remind you that eye safety during fall clean-up is just as important as protecting your hands or back. Here’s why safety glasses should be a must-have part of your fall yard work routine.

Common Eye Hazards During Fall Yard Work

Even everyday chores can expose your eyes to injury:

  • Flying Debris – Leaves, twigs, dirt, or rocks kicked up by leaf blowers, mowers, or rakes can strike the eyes.
  • Branches and Sticks – Pruning shrubs or gathering brush puts you at risk for scratches and pokes to the eye.
  • Chemicals – Fertilizers, pesticides, or cleaning solutions for gutters may splash and cause irritation or serious damage.
  • Dust and Allergens – Dry leaves and soil can stir up dust, mold spores, and allergens, leading to itchy, watery eyes.

Why Safety Glasses Are Essential

A simple pair of ANSI-approved safety glasses or protective eyewear can dramatically reduce the risk of eye injuries. Unlike regular glasses, safety glasses are designed to:

  • Resist impact from flying debris.
  • Provide side shield protection to block dust and dirt.
  • Stay secure during physical activity.
  • Offer tinted or UV protection options for outdoor use.

Wearing safety glasses is a small step that can prevent a major injury—and protect your vision for the long run.

Tips for Safe Fall Yard Work

  • Wear safety glasses or goggles whenever mowing, trimming, or using power tools.
  • Clear the area before mowing or blowing leaves to reduce flying objects.
  • Stay alert around branches—bend them away from your face when cutting or hauling brush.
  • Wash hands after yard work to avoid rubbing dust or chemicals into your eyes.
  • Keep protective eyewear accessible—store them with your tools so you never forget.

Keep Your Eyes Healthy This Season

Eye injuries can happen in an instant, but most are preventable with proper protection. This fall, don’t overlook the importance of safety glasses for yard work. Protecting your vision is one of the smartest investments you can make.

If you experience eye irritation, redness, or injury after outdoor chores, schedule an appointment with our office right away. Your eyes deserve the best care this season—and every season.

6 New Advances in Macular Degeneration Treatment for 2025

by ArticlesBlog

More than 200 million people around the world are living with age-related macular degeneration (AMD), a leading cause of vision loss among older adults. While treatments have existed for years to slow the disease, exciting new advancements are bringing us closer than ever to protecting—and even restoring—vision.

In this article, we’ll highlight six promising new treatments for macular degeneration, from gene therapy and stem cell research to cutting-edge drug delivery systems.

What Is Age-Related Macular Degeneration?

AMD is a condition that damages the macula, the central part of the retina responsible for sharp, detailed vision. Imagine the eye as a camera: light passes through the cornea, lens, and vitreous gel before reaching the retina at the back. The macula, located at the center of the retina, provides the ability to read, recognize faces, and see fine details.

When the macula deteriorates, central vision becomes blurry, distorted, or lost altogether.

There are two main types of AMD:

  • Dry AMD (most common): Caused by the buildup of protein deposits (drusen) under the retina, which interfere with macular function.
  • Wet AMD: Develops from dry AMD when the body tries to compensate by growing new blood vessels. Unfortunately, these vessels leak fluid and blood, leading to faster and more severe vision loss.

Current Treatments

Treatment depends on whether AMD is dry or wet, and on the stage of the disease. A comprehensive eye exam, including OCT scans and other tests, guides the care plan.

  • Dry AMD: No approved medications exist yet, but progression can be slowed with lifestyle choices like a nutrient-rich diet, smoking cessation, blood pressure control, and certain doctor-recommended supplements.
  • Wet AMD: The mainstay of treatment is anti-VEGF injections (Lucentis, Eylea, or Avastin), which block abnormal blood vessel growth and fluid leakage. Laser or photodynamic therapy may also be used.

Anti-VEGF therapy is highly effective—stabilizing vision in about 90% of patients and even improving it in 30%. However, the need for frequent eye injections can be burdensome.

6 Promising New Treatments for Macular Degeneration

The next generation of AMD care aims to target the root causes of the disease, restore lost vision, and reduce the burden of treatment. Here are six exciting developments:

1. Gene Therapy

Instead of repeated injections, gene therapy teaches the eye to produce its own anti-VEGF proteins. Two therapies—RGX-314 and ADVM-022—are in clinical trials for wet AMD, while HMR59 and GT005 show promise for slowing late-stage dry AMD.

2. Stem Cell Therapy

Stem cell therapy replaces damaged retinal pigment epithelial (RPE) cells with healthy lab-grown ones. If researchers can perfect safe, long-term delivery methods, this approach could potentially repair retinal damage and restore vision.

3. Complement Inhibitors for Late-Stage Dry AMD

In geographic atrophy, the advanced stage of dry AMD, the immune system can over-attack healthy retinal tissue. Complement inhibitors—including Syfovre (pegcetacoplan) and Izervay (avacincaptad pegol), both approved in 2023—slow the growth of retinal lesions by calming this overactive immune response.

4. Long-Acting Anti-VEGF Drugs

To reduce the burden of frequent injections, new long-lasting medications such as Eylea HD (aflibercept) and Vabysmo (faricimab) deliver extended protection with fewer treatments. Approved in 2023, these drugs can keep patients on track with less frequent office visits.

5. Implantable Drug Delivery Systems

The Susvimo implant (ranibizumab) continuously releases medication over six months. While it requires a minor surgical procedure and periodic refills, it offers the same results as standard anti-VEGF injections with far fewer appointments.

6. Light Therapy

The FDA approved photobiomodulation (the Valeda Light Delivery System) in 2024 for dry AMD. This non-invasive therapy uses red and near-infrared light to boost cellular energy and improve retinal function. Studies show it can slow disease progression and, in some cases, improve vision.

Looking Ahead

The introduction of anti-VEGF therapy revolutionized AMD care. Now, in 2025, we are entering a new era of treatments that not only slow progression but also aim to restore sight—while being less invasive and more patient-friendly.

For those living with macular degeneration, the future is brighter than ever.  For questions regarding macular degeneration, or low vision services, contact Dr. Bissell at 724-443-6767 or 724-226-0444.

Healthy-Aging-and-Your-Eyes

Healthy Aging and Your Eyes: A Guide to Preserving Vision

by ArticlesBlog

As we grow older, our bodies naturally change—and our eyes are no exception. According to the National Eye Institute, vision loss from age-related eye disease is becoming a major public health concern. Today, more than 40 million Americans are over the age of 65, and that number is projected to rise to 88 million by 2050.

Protecting your eyesight is vital to maintaining independence and quality of life. By understanding common age-related eye conditions and making healthy choices now, you can enjoy clearer vision well into your later years.

Common Eye Diseases in Older Adults

Aging increases the risk of several eye conditions. Awareness and early detection through comprehensive eye exams at Bissell Eye Care can make a significant difference in protecting your sight.

  • Cataracts – Clouding of the eye’s natural lens causes blurred vision, glare, and difficulty seeing at night. Cataracts are common but highly treatable—surgery is safe, effective, and can restore clear vision.
  • Glaucoma – Often called the “silent thief of sight,” glaucoma damages the optic nerve, usually from high eye pressure. It develops slowly and can cause permanent vision loss if not detected early. Regular exams are critical to monitor eye pressure and preserve vision.
  • Age-Related Macular Degeneration (AMD) – AMD affects central vision by damaging the macula, the part of the retina that lets you see fine details. While there’s no cure, lifestyle changes, supplements, and treatments can slow its progression.
  • Diabetic Retinopathy – High blood sugar levels can damage blood vessels in the retina, leading to vision loss. Managing diabetes and having routine eye exams are essential for prevention and treatment.
  • Dry Eye Syndrome – As tear production decreases with age, eyes may feel dry, irritated, or blurry. Over-the-counter drops, prescription medications, and simple lifestyle changes can bring relief.

Protecting Your Vision as You Age

Healthy aging starts with daily choices that support long-term eye health. Here’s what you can do:

  • Schedule comprehensive eye exams every year—even if you don’t notice changes in your vision. Many eye diseases develop silently and are most treatable in the early stages.
  • Eat a nutrient-rich diet including leafy greens, carrots, fish, nuts, and foods high in antioxidants like vitamins C and E, zinc, and lutein.
  • Manage chronic conditions such as diabetes and high blood pressure through medication, diet, and regular check-ups. These conditions greatly affect your vision.
  • Quit smoking—a major risk factor for cataracts, AMD, and many other health issues.
  • Protect your eyes from UV rays by wearing sunglasses with UV protection and a wide-brimmed hat.
  • Stay active with regular exercise, which improves circulation and lowers the risk of eye-complicating conditions.
  • Get enough sleep—rest gives your eyes time to recover and stay healthy.

A Clearer Future

Your eyes are your windows to the world and play a key role in maintaining independence as you age. By learning about common eye diseases and adopting healthy habits today, you can protect your vision for years to come.  Regular eye exams, a balanced diet, and a proactive approach to overall health are the cornerstones of keeping your eyes sharp and your outlook bright.  To schedule your annual comprehensive eye exam, call 724-443-6767 or 724-226-0444.

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.

The Link Between Diet, Hydration, and Healthy Summer Vision

by ArticlesBlog

Summer brings sunny days, outdoor adventures, and fresh seasonal foods—but did you know your summer habits can directly impact your eye health? What you eat and drink this season doesn’t just fuel your body; it can help protect your vision too. Here’s how smart choices around diet and hydration can keep your eyes comfortable and healthy all summer long.

 

Hydration: Quenching More Than Your Thirst

Hot weather and outdoor activities make dehydration a common summer concern—and your eyes can feel it first. When you’re dehydrated, your body produces fewer tears, which can lead to dry, itchy, or burning eyes. Staying hydrated by drinking plenty of water helps keep your eyes moist, supports tear production, and reduces the risk of irritation from heat, wind, and air conditioning.

Tip: Aim for at least eight glasses of water a day, and remember to drink even when you’re not thirsty—especially after outdoor sports, time at the pool, or walking in the heat.

Eat with Your Eyes in Mind

Summer is the perfect time to add colorful, nutrient-rich foods to your meals. Many summer fruits and vegetables contain antioxidants, vitamins, and minerals that help protect your eyes from sun damage and age-related conditions.

Some summer favorites to add to your plate:

  • Leafy greens (spinach, kale, collard greens): Rich in lutein and zeaxanthin, antioxidants that filter harmful light and protect your retina.
  • Berries (blueberries, strawberries, raspberries): Packed with vitamin C, which supports healthy blood vessels in your eyes.
  • Carrots and bell peppers: Excellent sources of beta-carotene and vitamin A, essential for good night vision and overall eye health.
  • Watermelon and cucumbers: Hydrating foods that help your body (and eyes) stay moist.

Don’t Forget Omega-3s

Dry eyes can be more noticeable in the summer heat. Adding foods high in omega-3 fatty acids—like salmon, walnuts, and flaxseeds—can help improve tear quality and reduce dryness.

Protecting Your Eyes from the Inside Out

While sunglasses with 100% UVA/UVB protection are essential, your diet and hydration habits add another layer of defense. Nutrients like lutein, zeaxanthin, and vitamin C help protect your eyes against the harmful effects of UV rays and oxidative stress, both of which increase in the summer.

Small Changes, Big Difference

Enjoy summer to the fullest by caring for your vision from the inside out:

  • Drink plenty of water
  • Choose fresh, colorful produce
  • Include omega-3-rich foods
  • Wear quality sunglasses with UV protection outdoors

Healthy summer vision starts on your plate and in your glass. If you’d like personalized tips for summer eye care or it’s time for your annual eye exam, our office is here to help! Call 724-443-6767 or 724-226-0400 to schedule your next appointment.

Vision Impairment and Low Vision After a Stroke: What You Should Know

by ArticlesBlog

A stroke can dramatically change many aspects of a person’s life, and vision is no exception. While most people associate strokes with weakness or speech difficulties, it’s important to recognize that strokes can also affect the way we see the world. Vision impairment and low vision are common consequences that can impact independence, safety, and overall quality of life.

 

How Strokes Affect Vision

A stroke occurs when blood flow to a part of the brain is blocked or when a blood vessel in the brain bursts. Depending on where the stroke happens, it can damage areas of the brain responsible for processing visual information. This can lead to a range of visual problems, including:

  • Hemianopia – Loss of vision on one side of each eye (often the same side).
  • Quadrantanopia – Loss of vision in a quarter of the visual field.
  • Blurred or double vision – Difficulty focusing on objects.
  • Visual neglect – The brain ignores part of the visual field, even though the eyes can still see it.

These issues often fall under the category of low vision, which means vision loss that cannot be fully corrected with glasses, contact lenses, medication, or surgery.

Living With Low Vision After a Stroke

Adjusting to vision impairment after a stroke can feel overwhelming, but support and resources are available. Here are a few strategies and tools that may help:

  • Comprehensive eye exams: Regular checkups with an eye care professional can help monitor changes and recommend tailored solutions.
  • Vision rehabilitation: Specialized therapists can teach techniques to scan the environment, improve coordination, and make the most of remaining vision.
  • Assistive devices: Magnifiers, specialized lighting, large-print materials, and electronic aids can improve daily functioning.
  • Home modifications: Simple changes like increasing contrast on stairs, decluttering walkways, and labeling items can help prevent accidents.

Don’t Face It Alone

Vision impairment after a stroke is life-changing, but there is help. Low vision specialists such as Dr. Bissell, occupational therapists, and stroke support groups can provide guidance, training, and emotional support. If you or a loved one has experienced a stroke, schedule a comprehensive low vision eye exam with Dr. Bissell to discuss your concerns and explore ways to adapt and live safely and independently. Call 724-443-6767 or 724-226-0444 to schedule your appointment.

Comparison of a healthy human eye and an eye with a clouded lens cataract - to prevent cataracts

Can You Prevent Cataracts? Lifestyle Tips for Healthier Vision

by ArticlesBlog

June is Cataract Awareness Month—an important time to understand how to protect your sight as you age. In recognition of Cataract Awareness Month, let’s take a closer look at what cataracts are, why early detection matters, and how healthy lifestyle choices can support long-term eye health.

Cataracts are one of the most common causes of vision loss worldwide, especially among adults over 60. Although cataracts are often a natural part of aging, there are proactive steps you can take to protect your vision and possibly delay their development.

What Are Cataracts?

A cataract is a clouding of the eye’s natural lens, which lies behind the iris and the pupil. As cataracts develop, they block light from passing clearly through the lens, making your vision appear blurry, foggy, or dim. Cataracts can form in one or both eyes and typically progress slowly over time.

Common symptoms of cataracts include:

  • Blurred or cloudy vision
  • Glare and halos around lights, especially at night
  • Faded colors
  • Frequent changes in eyeglass prescriptions
  • Difficulty seeing in low light

Can Cataracts Be Prevented?

While not all cataracts can be prevented—especially those related to aging—certain lifestyle habits may slow their development or reduce your risk. Here’s how:

Protect Your Eyes from UV Rays

  • Long-term exposure to ultraviolet (UV) light is a known risk factor for cataracts.
  • Tip: Always wear sunglasses with 100% UVA and UVB protection, even on cloudy days.

Quit Smoking

  • Smoking increases oxidative stress on the lens of the eye and significantly raises the risk of developing cataracts earlier.
  • Tip: If you smoke, talk to your doctor about quitting strategies and support.

Eat a Diet Rich in Antioxidants

  • Nutrients like vitamins C and E, lutein, and zeaxanthin may support eye health and slow the progression of cataracts.
  • Tip: Include colorful fruits and vegetables, leafy greens, and omega-3 fatty acids in your daily meals.

Manage Health Conditions Like Diabetes

  • Uncontrolled diabetes can accelerate cataract development.
  • Tip: Maintain healthy blood sugar levels through regular checkups, medication, and lifestyle changes.

Limit Alcohol Intake

  • Excessive alcohol consumption may increase the risk of cataracts.
  • Tip: Stick to moderate or occasional drinking when possible.

Why Early Detection and Treatment Matter

If left untreated, cataracts can significantly impair your vision and limit your ability to drive, read, or live independently. Fortunately, cataracts are treatable with safe and highly effective outpatient surgery, which replaces the clouded lens with a clear artificial one.

The key is catching them early—which is why regular, comprehensive eye exams are essential, especially after age 60. During your exam the doctors at Bissell Eye Care can detect early signs of cataracts and monitor their progression over time. Early diagnosis allows for timely treatment and better outcomes.

Your Vision Deserves Attention

Take steps to protect your eyes and encourage loved ones to do the same. Schedule your annual eye exam, wear your UV-protective sunglasses, eat for eye health, and talk to the doctors at Bissell Eye Care about any changes in your vision.

Is it Time for Bioptic Telescopic Glasses? What You Should Know.

by ArticlesBlog

For individuals living with low vision due to macular degeneration, Stargardt disease, diabetic retinopathy, or other eye conditions, everyday tasks like reading street signs, watching television, or recognizing faces can become difficult—even with regular glasses. If you’ve been told “nothing more can be done,” it may be time to explore a powerful tool in the world of low vision care: bioptic telescopic glasses.

What Are Bioptic Telescopic Glasses?

Bioptic telescopic glasses are a specialized type of eyewear that combines a prescription lens with miniature telescopes mounted toward the top portion of the lens. These miniature telescopes act much like binoculars, allowing the wearer to focus on distant objects with greater clarity. Patients can look through the regular portion of the glasses for normal viewing and tilt their head slightly to engage the telescope for enhanced distance vision.

This “look down, look up” design provides a natural way for users to alternate between their regular view and the magnified view—offering functional vision support without overwhelming the eyes.

How Do They Help with Independence?

Bioptic telescopes are often used to improve vision for activities that require seeing detail at a distance—such as:

  • Driving (where legal): Recognizing street signs or traffic lights
  • Watching TV or live performances
  • Reading publications
  • Reading classroom whiteboards or presentations
  • Facial recognition in social settings
  • Navigating public spaces like airports, stores, or parking lots

For many individuals, these glasses offer a renewed sense of confidence and greater independence. With the ability to see more clearly at a distance, patients can participate more fully in daily life, travel more freely, and rely less on others for help.

Are You a Candidate?

Not everyone with low vision qualifies for bioptic telescopic glasses. The ideal candidate typically has stable vision loss, strong motivation, and the ability to learn how to use the devices properly. A thorough low vision evaluation is essential to determine candidacy.

Why Choose a Doctor Trained by IALVS?

Dr. Bissell who is specially trained by the International Academy of Low Vision Specialists (IALVS), brings advanced expertise to the table.

Final Thoughts

If you or a loved one struggles with vision loss that isn’t corrected by regular glasses, it may be time to explore bioptic telescopic glasses. These specialized tools have helped thousands of individuals live more independently, pursue hobbies, and—in some cases—legally drive again.

Don’t give up on your vision. Schedule a consultation with Dr. Bissell, a low vision specialist trained by IALVS and see what’s possible. Call 724-443-6767 or 724-226-0444 today to learn more about low vision services.
