Low vision due to refractive error is the most common form of visual impairment. For people who cannot afford the services of an optometrist, being able to see poorly is almost as bad as not being able to see at all.
“Normal” vision is the ability to comfortably see what is around you, whether far away or near, without glasses. It’s often known as “20/20” vision, which means that the eye being tested is able to see at 20 feet what an eye with good vision can see at that distance. If you have 20/60 vision, you can see at 20 feet what a person with good vision can see at 60 feet. A change in vision between 20/60 and 20/200 is considered having low vision.
Low vision is fully correctable with surgery, contact lenses or eyeglasses. People with low vision typically have some functionally useful sight, but their ability to carry on everyday activities is hampered.
We are working with local partner organizations in India and Africa to bring diagnosis and optical services to people with low vision, at little or no cost to them.
