Nutritional treatment of common eye diseases is changing. For years now, the accepted treatment is based on something called 'AREDS' - Age Related Eye Disease Study. This was research performed over 6 years using the following dosages of several vitamins and nutrients used in combination:
500 milligrams of vitamin C;
400 international units of vitamin E;
15 milligrams of beta-carotene (or 25,000 international units of vitamin A);
80 milligrams of the dietary mineral zinc, in the form of zinc oxide; and
two milligrams of copper as cupric oxide, added to prevent copper deficiency anemia, a condition associated with high levels of zinc intake.
What was concluded was that the dose used reduced age related macular degeneration by 25%. Off of this research many products were formulated, including Ocuvite Preservision by Bausch & Lomb a collaborator within the study. There were however many lower cost formulas which matched the research backed dosage manufactured by other companies, such as 21st Century Health Care's Healthy Eyes.
Now a new study (AREDS II) is being performed, mainly in part to the promotion of nutrients such as Zeaxanthin, Astaxanthin, Lutein and Omega 3 to see whether the inclusion of these can have further influence on the effects of macular degeneration and cataracts. The research was started in 2006 and if it follows the same pattern as previous will conclude in 2013.
