Subnormal Vision

(HealthDayNews) -- Subnormal vision, also known as low vision, is often caused by such eye diseases as macular degeneration or cataracts, according to Barnes Jewish Hospital.

Since prescriptive eyewear can't correct the condition, vision may be reduced to the point where daily activities like reading, writing or driving are difficult to perform.

If you suffer from subnormal vision, an eye care specialist can help you maximize the vision you have. Hand-held magnifiers, spectacle magnifiers, video-projected magnifiers and talking books can help improve daily living.
