Reduced vision is defined as vision that can not be corrected completely using either contact lenses, eyeglasses, or surgery, and is blurry (at the level of at least 20/70), or limited in its view field. Low vision is sometimes caused by injury to the eye or brain, and it can be inherited. However the main cause of low vision is eye disease, including diabetic retinopathy, glaucoma and macular degeneration.
If you have low vision you have some sight. However completing normal activities, including driving and reading, can be hard or even impossible.
Low vision is a condition that the elderly suffer from, although it is possible for children and middle-aged patients to have low vision. After a life of seeing normally, losing your vision can be hard, or even traumatic, and can potentially lead to frustration, or even depression.
