How to Prevent Cataracts

No one knows for sure why the eye´s lens changes as we age, forming cataracts. Researchers are gradually identifying factors that may cause cataracts, and information that may help us to prevent them.

Recent studies show people living in high altitudes or those who spend a lot of time in the sun develop cataracts earlier than others. Ophthalmologists now recommend wearing sunglasses and a wide-brimmed hat to lessen the eyes exposure to UV light. Other studies suggest people with diabetes are at risk for developing a cataract, as are users of steroids, diuretics, and major tranquilizers. But more studies are needed to differentiate the effect of the disease from the effect of the drugs themselves. The location and the density of the cataract have a lot to do with what symptoms you experience and how soon you experience them. When symptoms begin to appear, new glasses, strong bifocals, magnification, appropriate lighting, or other visual aids may improve vision for a while. You should consider surgery when poor vision threatens your enjoyment of life or your ability to maintain an independent lifestyle. Cataract surgery is the most frequently performed surgery in the United States, and one of the most consistently successful. Over 90% of the people who have cataract surgery regain useful vision, somewhere between 20/40 and 20/20. Judith Lee
