Cataracts are clouding of the eyes; they are the most common reason why many lose their vision, especially those over the age of 40. Keep in mind; over 22 million people in the US have cataracts.
Types of cataracts
There are two types of cataracts; nuclear and cortical cataracts. A nuclear cataract is found deep in the central part of the nucleus. The cortical cataract has white-like particles that begin in the edges of the lens and then work their way to the center.
What are the signs and symptoms of cataracts?
In the beginning, a cataract starts small and for a while does not affect your vision. However, at times, you may sense that your vision is blurred. You may also notice at night that oncoming headlights have more of a glare than usual.
What causes cataracts?
It is important to know; no one knows what causes cataracts but advancing age may be one factor.
• Other risk factors are ultraviolet radiation from the sunlight, hypertension, diabetes, obesity and smoking.
• Additional risk factors are a previous injury to the eye, hormone replacement therapy, too much alcohol and a family history of cataracts.
Can I prevent cataracts?
Research, at this time, does not show how to prevent cataracts; however, certain nutrients and nutritional supplements may do something to prevent them. Higher doses of vitamin E may help as well as taking vitamin C and consuming foods that have omega-3 fatty acids in them. One step that may also help is wearing protective sunglasses; sunglasses that block all of the sun’s UV rays.
Other ways to prevent cataracts
Besides the ways to prevent cataracts, there are other ways to prevent them such as having a yearly eye exam, not smoking, cutting back on wine or cocktails, keeping your diabetes under control and avoiding corticosteroid medications.
