Many people have heard the word but still wonder, “what are cataracts?”. This common health condition affects many individuals every year, and there are ways to prevent or stop the problem. In order to learn how to lower your chances of developing a cataract, you must first understand what they are. The loss of sight can severely hinder a person’s ability to function independently, which can make this health problem a very serious concern.
Cataract Basics
Behind your iris (or the colored area of your eye) is a natural lens. In a healthy eye, this lens is clear and helps focus the light that passes through your eye. The focused light is sent through the retina which makes the image visible. This process is altered when a cataract begins to form. The cataract develops on the lens, so from the start of the process your sight is affected. A cloudy blockage covering the lens will disperse light, which makes the image you see blurred.
The Development of Age Related Cataracts
What are cataracts that develop as a person ages? This is perhaps the most commonly thought of cause. As our age increases, our body changes as well. Over time, the lens of the eye will slowly begin to lose elasticity and become thicker. This can eventually make it harder to see through as portions begin to cloud over. The older we get, the worse this problem will become. Cataract development is not limited to one eye, either. A person can experience hindered vision in both eyes because of multiple cataracts.
Other Cataract Causes
Age is not the only factor that can cause cataracts. Even infants can develop congenial cataracts. Many other factors can influence a person’s eye health, including exposure to potentially dangerous substances such as lead, radiation, or ultraviolet light. Diabetes or prolonged steroid use can also cause a cataract.
