Macular Degeneration
What is the macula?

The human eye is similar to a camera. The retina of the eye is like the film of a camera, it is the part of the eye that actually "takes the picture." The macula is the central part of the retina where all the fine vision or reading vision takes place. The macula is used when the eye looks directly at something.

What is macular degeneration?

Age-related Macular Degeneration (AMD) is the leading cause of irreversible blindness in Americans 65 years of age or older. The central fine vision required for "straight ahead" viewing such as reading and driving is damaged in this condition.

What is difference between Dry Macular Degeneration vs. Wet Macular Degeneration?

Dry Macular Degeneration is the less severe type of Macular Degeneration. In Dry Macular Degeneration the central retina has become distorted, pigmented, or most commonly thinned. The "wet" form of macular degeneration is a worse disease. Patients with wet macular degeneration can develop abnormal blood vessels under their retina which can leak and bleed into the macula.

Is there a cure for macular degeneration?

No, but there now is a way to lessen the risk of loss of vision from this disease, but read on.

What is AREDS?

The Age-Related Eye Disease Study (AREDS) was a major ten year study sponsored by the National Eye Institute (NEI), one of the Federal government's National Institutes of Health, and was conducted at 11 major medical center research facilities around the country. The study, completed in October 2001, sought to determine whether taking vitamin and/or mineral supplements could help prevent, treat or cure certain eye conditions.

What did AREDS find?

AREDS found that people at high risk of developing advanced stages of AMD, a leading cause of vision loss, lowered their risk by about 25 percent when treated with a high-dose combination of vitamin C, vitamin E, beta-carotene, and zinc.

Who should take these vitamins?

The study found that patients with intermediate AMD or advanced AMD in one eye but not the other were more likely to benefit. Your eye care doctor will tell you if you should be taking Viteyes.

What are the daily doses of the vitamins and minerals recommended?

500 milligrams of vitamin C; 400 international units of vitamin E; 15 milligrams of beta-carotene; 80 milligrams of zinc as zinc oxide; and two milligrams of copper as cupric oxide (Copper was added to the AREDS formulations containing zinc to prevent copper deficiency, which may be associated with high levels of zinc supplementation).

Does Viteyes®contain the vitamins and minerals in the proper doses recommended by AREDS?

Yes. In addition Viteyes™ AREDS Formula Plus Lutein and Viteyes Smoker's Formula Plus Lutein have the added potential benefit of Lutein.

Can I also take my daily multivitamin with Viteyes?

The AREDS study proved that it is safe to take the AREDS recommended vitamins (Viteyes) and a multivitamin. However, we now offer Viteyes® Multivitamin AREDS Companion which reduces the risk of overdosing by taking uneeded antioxidants and zinc in your current multivitamin which are already present in Viteyes AREDS Formulas. It is a multivitamin formulated equivalent to Centrum® Silver but does not contain Vitamin A, Vitamin C, Vitamin E, Zinc, and Copper, ingredients already present in Viteyes AREDS Formulas.

What is Lutein?

Lutein is a potent antioxidant carotenoid, found in abundance in fruits and green leafy vegetables. Lutein is also one of the dominant pigments found in the macular region of the healthy retina. Because of this, many eye doctors recommend Lutein to their patients with macular degeneration.

Why wasn't Lutein included in the AREDS?

Lutein was not available when AREDS was started but it probably would have been included if the study were started now.

What are the potential side effects of the AREDS vitamins and minerals?

The AREDS participants reported few side effects from the treatments. About 7.5 percent of participants assigned to the zinc treatments -- compared with 5.0 percent who did not have zinc in their assigned treatment -- had urinary tract problems. Yellowing of the skin, a well-known side effect of large doses of beta-carotene, was reported slightly more often by participants taking antioxidants.

Do the AREDS vitamins also lower the risk of developing cataracts?

Despite the evidence that these nutrients did not lower the risk of cataract development over the seven-year period of the study, an effect over a longer period of time at this point cannot be ruled out.

What are the advantages of Viteyes over competing products?

Viteyes requires only 2 easy to swallow capsules daily verses 4 tablets sold by the leading distributor. Viteyes contains Lutein one of the dominant pigments found in the macular region of the healthy macula and recommended by many eye doctors.
