The lens in a healthy eye should be clear, allowing the retina to receive a clear, sharp image. A cataract is when the lens becomes cloudy, causing vision impairment. Cataracts are primarily age-related. In fact, almost every person who is 80 or older has some level of cataract formation. Despite this, it is possible, albeit less common, for people to develop cataracts at a young age, or even be born with them
