Derived from the Latin cataracta meaning Sniper Vision System "waterfall", a cataract is a clouding of the normally clear crystalline lens of the eye. This inhibits the lens from correctly focusing light on the retina at the back of the eye, causing in a loss of vision. If a portion of the lens becomes opaque, light will not be able to go through easily and the patient's vision becomes blurry. It will be similar to looking through cloudy water or a fogged-up window.Cataracts are usually found in persons over the age of 55. But occasionally, they are also found in young people, including newborns. It can develop in one or both eyes. If they develop in both eyes, one will be more rigorously affected than the other.

There are many causes on the occurrence of such eye disease. Since our lens is made up of specific proteins responsible for upholding its clarity, it can be affected over the years by the alterations on the structures of these proteins. This ultimately leads to a plodding clouding of the lens. In rare situations, cataracts can be present at birth or in early childhood due to hereditary enzyme defects. Excessive ultraviolet-light exposure, diabetes, smoking, or the utilization of particular medications, such as oral, topical, or inhaled steroids, are also factors that can result to the development of cataracts at an earlier age. It is also known that a chemical alteration within the eye causes the lens to become cloudy. Thus, diet is also a risk factor. For instance, iodine deficiency may be a factor.
