What is Low Vision?

Low vision is where you have done traditional corrective vision methods such as glasses, contacts, medication or Lasik and are still unable to perform the daily tasks that you desire. You have difficulty with driving, watching TV, writing, recognizing faces or reading the paper. Through our various techniques, medications, aids and adjustments to daily life, you can return to many of your daily activities.


Low vision is considered a significant vision impairment that usually results from serious eye disease or an injury. The vision loss, which is characterized by either reduced visual acuity (to 20/70 or worse) or reduced field of view, can’t be fully corrected with glasses, contact lenses, medication or surgery.

Low vision can affect both children and adults but is more common in the elderly, who are at greater risk of eye diseases such as glaucoma, macular degeneration, and cataracts, which are some of the most common causes of the condition.

Patients with low vision may have complete central or peripheral vision loss, blurry vision, poor low-light vision, loss of light sensitivity and/or loss of contrast, making daily activities such as writing, watching TV, driving or reading difficult or impossible. Since the vision loss can’t be corrected, low vision requires significant adjustments to daily life and the help of techniques and specialized low vision aids to help maximize the remaining vision to increase independence and quality of life.

Retinitis Pigmentosa is a rare, genetic disease that involves damage to the photoreceptors in the retina. These retinal cells line the back of the eye and are highly sensitive to light. When they don’t function properly, the person with RP suffers a loss of peripheral vision, loss of central vision, and trouble seeing at night – all of which lead to low vision. Our Lancaster optometrists are knowledgeable and experienced in treating retinitis pigmentosa to make the most of any remaining vision. We will fit you with the most suitable low vision aids, working with you patiently to promote independence and help you do the things you love.

CentraSight is a tiny device that can be implanted into your eye to assist with vision loss caused by end-stage age-related macular degeneration (AMD). The CentraSight telescope projects images onto the healthy part of your eye that was not damaged by AMD. Your other eye sees peripheral vision, so with both eyes teaming together – you have a wider field of view. Candidates for this implantable telescope must be a certain age and cannot have had cataract surgery. Our Lancaster low vision specialists will assess your situation and condition to determine if you are a good candidate for this cutting-edge device. Contact us to find out more about CentraSight.

There are many risks involved in driving with low vision. For example, you may not be able to see traffic lights or road signs clearly. However, losing your ability to drive can be devastating. You need to depend upon others to run your errands and get you to where you need to go. Fortunately, a range of aids is available to help you drive safely. Our Lancaster optometrists can match you with bioptics and telescopic glasses to magnify everything you need to see while on the road. In New York, drivers need 20/100 vision with glasses or contact lenses to stay behind the wheel. With low vision aids like telescopic lenses, we can help sharpen your sight to 20/40 vision!

Age-Related Macular Degeneration (AMD)

Diabetic Retinopathy

Juvenile Macular Degeneration

Age-related macular degeneration damages the macula, which is the part of your eye responsible for sharp central vision. With this common and painless eye disease, objects straight in front of you and fine details become blurred, and you may have trouble seeing in dim light. In some people, AMD progresses very gradually, and you may not notice any problems until the disease has advanced to a late stage. A comprehensive eye exam is the only reliable way to detect AMD, contact our Lancaster eye doctor to schedule regular eye exams – especially after age 50. If you have age-related macular degeneration and have been diagnosed with low vision, we can help you use your remaining vision to its full potential, so you maintain a high quality of life.

Diabetic retinopathy generally presents no symptoms at the beginning, but over time you may notice symptoms such as dark spots, blurry vision, many floaters, weak color vision, and fluctuating visual acuity. These complications occur as a result of extra sugar circulating through the bloodstream, which leads to a blockage of the small blood vessels in your eyes. The blocked vessels interfere with blood flow to your retina, and your eye attempts to remedy the situation by growing new, unhealthy vessels – which are weak and leak fluid. Treatment is available for diabetic retinopathy, particularly when diagnosed early. That is why we urge all patients with diabetes in Lancaster to book regular eye exams.

Glaucoma is the top cause of preventable vision loss and blindness among adults in North America. This eye disease is characterized by high pressure of the intraocular fluid in your eyes. Elevated pressure levels eventually injure the optic nerve, which leads to vision loss. To prevent the damaging effects of the most common types of glaucoma – open-angle glaucoma and narrow-angle glaucoma – it is essential to visit our Lancaster optometrist for routine comprehensive eye exams with glaucoma testing. The earlier that glaucoma is diagnosed, the more effective the treatment.

Cataracts are a very common eye disease, affecting more than half of all people over age 80. Symptoms include blurred and hazy vision. In the beginning, many people do not require treatment. Once cataracts progress, our Lancaster optometrist can assist you to live with the vision loss by fitting specialized lenses or low vision aids. If your eyesight continues to deteriorate, cataract surgery is ultimately the best option for most people. We offer full co-management services for cataract surgery in Lancaster.

In order to see clearly, your functional visual system must work properly. A healthy visual system depends upon brain and eye coordination; the eyes send visual cues through the nerves to the brain, where they are processed and sent back to the eyes. If you have low vision due to a brain damage from a stroke and, our Lancaster low vision specialists can help.


With significant vision loss, it can become challenging to complete common daily tasks including reading, writing, cooking, and housework, watching television, driving or even recognizing people.

Initially, it is an adjustment to learn how to function with impaired vision but the good news is there are numerous resources and products available to assist.
