A cataract is an opaque (cloudiness) build-up of damaged proteins in the lens, which constitutes the leading cause of visual decline in those over 65. Free radical damage is believed to play a major role in the development of cataracts. They are more likely to occur in those who smoke, have diabetes, or are exposed to excessive sunlight. Cataracts usually develop slowly without any pain or redness of the eye. The most common symptoms of a cataract are fuzzy or blurred vision, increasing need for light when reading or doing other close work, visual disturbances caused by bright lights (e.g., sunlight, car headlights), faded color perception, poor night vision, and frequent need to change eyeglass or contact lens prescriptions. There is substantial evidence that supplementation with certain antioxidant vitamins can reduce the risk of cataract development and slow down the progression of existing cataracts.
A high potency multiple vitamin and mineral should contain important dosages of antioxidants that have been shown to slow the progression of cataracts and defend the lens of the eye from free radicals that are largely responsible for cataract development.
A nutrients enhancing glutathione should provide important antioxidant defense to further prevent free radical damage associated with cataracts.
Additional Supplement Considerations
(500 – 1000 mg per day) Quercetin has been shown to block a key enzyme (aldose reductase) that is partially responsible for cataract development, especially in diabetic patients.
