Blindness

Common Name(s)

Blindness

Blindness is a lack of vision, or a loss of vision that cannot be corrected with glasses or contact lenses. In the United States, a person is considered legally blind if their vision is less than 20/200 with glasses. There are two types of blindness: partial, meaning very limited vision, and complete, meaning the individaul cannot see anything including light. Blindness can be caused by a number of things and can occur gradually or suddenly. Some causes include: accidents/injuries, diabetes, glaucoma, and macular degeneration, cataracts, blocked blood vessels, birth complications, complications from eye surgery, stroke, and lazy eye. To diagnose blindness, a complete eye examination must be conducted, and treatment varies depending on the cause of the blindness. There are many services that can provide support to people with visual impairments, for example, low-vision specialists can help patients with long-term vision loss care for themselves and live safely.
