Cataract is an eye condition which causes blurring and clouding of vision. Initially a person faces nearsightedness along with problems reading and driving especially during nights. The clouding of eye lens is often age related problem. Sometimes, it is often seen in newborns. As a person ages, his eye lens becomes thicker and more transparent. Tissues within lens may get broken and get saturated in a clump. This clump gradually grows denser and interferes with light that is passed through lens to retina. As a result, vision becomes blurred of foggy. Cataracts cause clogging of lens which cannot usually develop in both the eyes. They may not be symmetrical. Symptoms: - Initially, cataract affects only the smaller part of eye and thus symptoms may not be visible. However, as it increases in size, it causes more distortion of light and clouding of vision.

But with time, yellowing of lens occurs which hinders the vision. Further clouding of vision may occur when the lens turns brown. At the advanced stage, difficulty is experienced in differentiating various shades of a color. •Cortical Cataracts: - They are opaque and white in color. They usually affect outer edge of lens. As the condition progresses, center of the lens also gets clouded which hinders passing of light through it. Individuals who develop this condition have problems with glare. •Posterior subcapsular cataracts: - These opaque formations develop in the back side of lens, usually at the spot where light enters the retina. They cause interference with reading vision. An individual having this condition may experience halos, glare problems and reduced vision in bright light.
