Preventing Cataracts and Cataract Symptoms
Cataract Symptoms
As we age, the transparency of the lens of our eyes decrease. Change in the lens protein causes the lens to lose its pristine transparency and gradually become milky or whitish in color. These changes result in a swelling of the fibers, which in turn causes a distortion of the image. It can occur in one or both eyes.
Most people over 60 have some degree of cataract formation. It is the leading cause of blindness in the United States.
Common cataract symptoms include:
- cloudy, blurry, or foggy vision
- glare from bright lights
- poor night vision
- double vision
- pupil becomes gray in color and later a milky-white.
Preventing Cataracts
Sunlight and other sources of ultraviolet light can hasten formation of cataracts. Wear eyeglasses that block both UVA and UVB light.
Antioxidants play an important role in protecting the lens from free radical damage. Antioxidants, such as vitamin C, vitamin E, carotenes, and selenium, greatly lower the risk of developing cataracts.
Not only can vitamin C help in preventing cataracts, it has been shown to slow the progression of cataracts. In one study[1], 450 individuals with cataracts were placed on a daily diet that consisted of 1 gram of vitamin C. During the 11 year study, the majority of these people showed no evidence of progression. In similar people without this treatment, surgery was required within 4 years.
Hachimijiogan, an ancient Chinese formula, helps increase the level of antioxidants at the lens of the eye.
Eat more fresh fruits and vegetables (including yellow-orange vegetables) and legumes. Limit salt intake and avoid fried foods, cigarettes, and other sources of free radicals.
Glutathione, a small protein, plays an important role in maintaining a healthy lens. The lens normally has high concentrations of glutathione and in individuals with cataracts, the levels are diminished.
Riboflavin is required for the regeneration of glutathione in the lens. About 33% of individuals over 65 years of age have low levels of riboflavin. Although riboflavin is important in preventing cataracts, taking too much can lead to cataract formation.
Have your eyes examined regularly:
- every 2 years for those under 60
- every year for those 60 and above and for those with diabetes
- every 6 months for those on long term use of corticosteroids.
