Cataracts Are the Main Cause of Vision Loss in People Over 40
Cataracts are cloudy areas that form in the lens, which is normally transparent, and are the main cause of vision loss in people over 40 years of age. It is estimated more than 40 percent of Americans aged 75 years or older have some degree of lens clouding; and over half of people 80 or older have their vision significantly impaired by cataracts or have had cataract surgery. Surgery is generally recommended once vision is impaired to a degree that people have trouble reading, driving and recognizing faces. Today the surgery is a quick, safe procedure, replacing the cloudy lens with a clear plastic one.
Doctors say there are things people can do to reduce their risk of developing cataracts with quitting smoking at the top of that list. Medical News Today reports on studies linking a 3-fold increase of smoking to cataracts as well as raising the risk of several other eye conditions. A healthy diet of fresh fruits, vegetables, whole grains, good quality fats (avocados, olive oil, and omega oils) and lean animal-sourced or plant-sourced proteins additionally reduces the risk of cataracts.
Maintaining a healthy weight is important as obesity increases your risk of developing type 2 diabetes, which is a risk factor for cataracts. Other ways to reduce your risk include wearing UV blocking sunglasses when in the sunlight and getting at least 7 hours of sleep each night. The risk for cataracts also increases with age, family history, and a history of eye inflammation or injury.
If you are not ready for surgery yet, doctors say stronger glasses and brighter lights may help. Keep up with regular eye exams and renew your eyeglass prescription as needed. Wear sunglasses in the sun and avoid night driving. As your cataracts continue to develop and eyesight worsens, at some point you will most likely need surgery.
