Low vision is a visual impairment, not correctable by glasses, contact lenses, medicine, or surgery, that interferes with a person's ability to perform everyday activities.
Causes of Low Vision include:
- congenital problems or disorders
- traumatic injury to the eye or brain
- systemic diseases
- adult onset diseases
Some warning signs include the following:
- Trouble reading, cooking, or sewing.
- Trouble seeing because the lights don't seem as bright as usual.
- Trouble recognizing the faces of friends and relatives.
- Trouble crossing the street or reading signs.
A person who is having these vision difficulties should immediately make an appointment with an eye care professional for an eye examination. If the person's vision cannot be treated by conventional methods, such as glasses, contact lenses, medication, or surgery, then he or she should ask the eye care professional for information about vision rehabilitation. These services may include eye examinations, a low vision evaluation, training on how to use visual and adaptive devices, support groups, and training on how to perform everyday activities in new ways.
