Cataracts can impair vision quality and eye care health. It is a process by which the lens in the eyes becomes cloudy and vision is affected. If left untreated contributes to blindness in individuals over 40 years of age.
There are three types of cataracts a nuclear cataract, a subcapsular cataract, and a cortical cataract. Each is unique in appearance, yet all three affect the lens in the eyes. The nuclear cataract develops in the center or nucleus of the lens. This is the most typical form that appears as we age. The subcapsular cataract starts in the back of the lens. Individuals with concurrent medical conditions like diabetes have a higher risk. In addition, people who need to take high doses of corticosteroid medications for a disease like rheumatoid arthritis, asthma, or cancer can develop cataracts. The last type is a cortical cataract. It happens in the part of the lens that borders the central nucleus. Lenses take on a while sheen that travels to the center resembling a wheel.
