Low vision is a visual impairment, not correctable by standard glasses, contact lenses, medicine, or surgery, that interferes with a person’s ability to perform everyday activities. Low vision is not just part of getting older. Normal changes in our eyes and vision occur as we get older. However, these changes don’t usually lead to low vision. Most people develop low vision because of eye diseases and health conditions such as macular degeneration, cataract, glaucoma, and/or diabetes. While vision that’s lost cannot always be restored, many people can make the most of the vision they have. Millions of Americans have low vision.
