Low vision refers to vision loss that cannot be corrected with glasses, contact lenses, medical treatment, or surgery. Unlike total blindness, some vision remains, but both blindness and low vision cause trouble performing activities of daily living. Low vision can affect people of all ages – both children and adults.
Symptoms of low vision include:
- Difficulty focusing
- Blurry central or peripheral vision
- Poor contrast detection (difficulty distinguishing objects from similar colored backgrounds)
- Poor depth perception
- Bumping into things
- Holding objects very close to see them
Patients with low vision experience problems with reading, writing, driving, looking at screens (including phones, computers and televisions), seeing at night or in low light, cooking, recognizing faces, and more.
What causes low vision? The causes of low vision usually fall into three categories: congenital (present at birth), acquired (develops after birth), or inherited (runs in a family). Some conditions that can lead to low vision include macular degeneration, cataracts, brain injuries, eye injuries, and eye cancer, among many others.
How is low vision diagnosed and treated?
Low vision is diagnosed with a complete eye exam. Once diagnosed, the eye doctor will most likely put in a referral to a specialist for vision rehabilitation. The specialist can help make the most of the affected person’s remaining vision by offering guidance, devices and resources. Some of these include:
- Magnifying devices
- Audio options for phones, smart watches, books and home devices
- Large print and high contrast options for reading materials
- Labels for things in the home utilizing colors, large print or textures
- Support groups and mental health resources to help navigate emotional and social aspects
Low vision can present many challenges, but there are resources and support available to help those affected preserve their remaining vision and maintain as much independence as possible.
