Cataracts occur as a result of protein buildup in the eye lens. This makes the lens cloudy and blurry. Once the lens get cloudy, light ceases to pass through the lens which results in losing vision. As formation of new lens occurs outside of the lens, the existing cells get compressed in the lens’ center leading to a cataract. Cataracts can be treated at early stages since there are several obvious symptoms and signs that can alert an individual if they may have developed a cataract.
