The simplest definition of a cataract is that it is a clouding of the lens of your eye. The lens is normally clear in a healthy eye. This clouding normally develops slowly over time and symptoms may at first be nearly imperceptible. They will, however, usually become more advanced over a period of time. Left untreated, cataracts can progressively cause blindness and are the number one cause of blindness in the world.
If you have several of the following signs and symptoms, there’s a good chance you may have cataracts.
Cataracts may cause a change of color in one or both of the eyes. Your eyes may begin to look yellowish or even light brown in color. This is caused by clumps of protein in the eyes that can cloud your lens. This will then result in the light having a yellow color to it when it comes into your eye. It has sometimes been compared to wearing sunglasses that block violet and blue light. In advanced cases, the normally black lens of the eye may appear to have turned a milky color. In these cases, when the cataract has been left untreated, vision is often reduced to only being able to distinguish between light and dark.
