Your lens inside of your eye works in essentially the same manner as a camera lens, through bringing the light onto the retina. It works to adjust the focus of the eye, allowing us to see things in a clear manner, regardless of if they are up close or far away. The lens itself is composed of a mixture of protein and water. Proteins are arranged in a manner that works to keep the lens clear and allow light to pass through.
As we grow older, the proteins may join together and cloud your lens. Over time this cataract will grow larger and cloud more and more of the lens, which makes it difficult to see. No one knows the exact reason why the lens changes as we grow older, but researchers are working to identify the contributing factors that lead to cataracts and any information that can help to eliminate them.
A lot of studies have suggested that being exposed to ultraviolet light has contributed to the development of cataracts, which is why doctors recommend users to wear sunglasses or a hat to avoid overexposure to sunlight. There may also be other types of radiation that have contributed to the cause. In 2005, there was a study in Iceland that suggested airplane pilots were at an increased risk of developing cataracts than pilots who were not exposed to any radiation. Astronauts are another group at risk for cosmic radiation.
People who have diabetes are another group that may be at an increased risk. Users of steroids, tranquilizers and diuretics are also susceptible, but there are additional studies needed to determine the exact effects from the drugs. Some doctors believe that diets that are high in vitamins C and E, antioxidants and selenium may slow the growth of cataracts. However, eating a large amount of salt may put you at an increased risk. Other factors that contribute to the condition include smoking, alcohol consumption and air pollution.
There are additional studies needed to determine whether or not lead and age play a role in cataract development. Researchers are looking into whether or not hormone replacement therapy (HRT) is another factor that can increase your chances of developing the disease, as well as how severe the condition may end up being. Using alcohol along with HRT may increase your occurrence of cataracts by almost 50 percent, compared to others.
