Cataracts are a scary proposition. They cloud your eye's lens and ultimately block your vision. And they're pretty common in people 65 and older. But what causes cataracts? And is there anything you can do to protect your eyes? Although age is a risk factor, you might be able to slow the process by following these tips:
- Wear sunglasses. The sun's ultraviolet rays can speed up tissue damage. Buy glasses that guard against both types of rays, UVA and UVB.
- Eat healthy foods. Vitamins in fresh vegetables and fruits might protect the lens. Other foods that help support eye health include whole grains, nuts and seeds.
- Control diabetes. High blood sugar levels irritate eye tissue and damage proteins in the lens. To reduce your chances of developing diabetes, stay at a healthy weight.
- Quit smoking. Studies indicate that smokers might experience cataract symptoms earlier than nonsmokers. Cigarettes speed up the body's aging process and increase the risk of high blood pressure, which might be another contributing factor for cataracts.
- Limit alcohol. People who have four or more drinks a day might be more likely to get cataracts, research has shown.
- Check on your medication. Long-term use of certain drugs including steroidal eye drops for seasonal allergies, corticosteroids for asthma, tranquilizers and treatments for psoriasis and other skin conditions might raise the risk of cataracts. Talk to your primary care physician and eye doctor.
- Have regular eye exams. The earlier cataracts are diagnosed, the easier they are to treat using a variety of techniques.
- Don't ignore symptoms. These include clouded or blurred vision, increasing problems with night vision, sensitivity to lights and glare, seeing halos around light and a fading of colors. See a doctor whenever you notice a significant change in your sight.
