Low Vision

Many people with greatly diminished vision can now be helped to improve their quality of life.  In fact, very few people are “blind” in the sense that they cannot perceive anything.  When someone has reduced vision that cannot be corrected with standard methods such as glasses and contacts, they may encounter problems functioning in everyday life and are said to have low vision.

In the state of Tennessee, a person with vision that cannot be corrected beyond a visual acuity of 20/200 is considered legally blind. It is important to remember, however, that visual acuity is not a complete indication of visual function.  A person with good visual acuity may have other visual deficits that hinder them from functioning well.

There are many causes of low vision. Some of the more common causes are listed here.

• Macular degeneration

• Diabetic retinopathy

• Retinitis pigmentosa

• Retinopathy of Prematurity

• Cataracts
