eye and vision conditions
The leading causes of low vision and blindness in the United States are age-related eye diseases: macular degeneration, cataract and glaucoma. Other eye disorders, eye injuries, and birth defects can also cause vision loss. Whatever the cause, lost vision cannot be restored.
Also to know is, what are the types of visual impairment?
Common types of visual impairment
- Loss of Central Vision. The loss of central vision creates a blur or blindspot, but side (peripheral) vision remains intact.
- Loss of Peripheral (Side) Vision.
- Blurred Vision.
- Generalized Haze.
- Extreme Light Sensitivity.
- Night Blindness.
- Severe, sudden eye pain.
- Recurrent pain in or around the eye.
- Hazy, blurred, or double vision.
- Seeing flashes of light or sudden bright floating spots.
- Seeing rainbows or halos around lights.
- Seeing floating "spider webs"
- Seeing a "curtain coming down" over one eye.
Similarly, is visually impaired the same as blind?
The definition of visual impairment is “a decrease in the ability to see to a certain degree that causes problems not fixable by usual means, such as glasses.” Blindness is “the state of being unable to see due to injury, disease or genetic condition.” Totally blind refers to a complete loss of sight.
When visual impairment is caused by these problems, often treatment is readily available. Refractive errors can be corrected with glasses, contact lenses or refractive surgery. Cataracts – the clouding of the lens – are commonly treated with a surgical procedure that is among the most frequently carried out in the US.
