Blindness PPT: Definition, Symptoms, Risk-Factors and Complications

If you are entirely blind, you cannot see anything, including light. (When people refer to “blindness,” they typically mean total blindness.) Most states in the US consider someone legally blind if their vision is worse than 20/200, even with glasses or contact lenses. The term “vision loss” describes a partial or whole loss of vision. This visual loss could occur suddenly or gradually. Some forms of vision loss don’t result in total blindness.
