Sunshine Link to Cataracts
A cataract is a clouding over the eye lens that makes images appear blurry. It’s like trying to see something outside a frosted window. The lens in your eye is usually clear; it helps the eye focus so we can see things close up or far away. It is made up of protein and water that allow light to pass through it. As we age, the protein may bunch together and cloud the lens. This develops into a cataract and it becomes harder to see clearly.
Many studies suggest that ultraviolet (UV) light exposure causes cataracts. Eye care experts recommend the use of sunglasses that screen out UV light rays, or regular glasses with a clear anti-UV coating, and brimmed hats or visors to further protect the eyes.
Other studies indicate that diabetes, the use of steroids, diuretics and tranquilizers, eating too much salt, air pollution, cigarette smoke, exposure to lead and heavy alcohol use may cause cataracts.
If symptoms become severe, and loss of vision interferes with your daily routines, surgery may be recommended. During surgery, the clouded lens is removed and replaced with a clear, plastic intraocular lens implant.
