Doses of lutein of 10 mg per day and zeaxanthin of 2 mg per day are recommended on the American Optometric Association website.

Eating fish several times a week will lessen your chances of getting ARMD, according to The Eye Digest website.
The most beneficial carbs for eye health are products made with corn. Corn chips, tortilla chips and corn bread are delicious and rich in lutein and zeaxanthin.
