These minerals are especially important for good vision and may be found in many food sources in a well balanced diet.
Chromium
Chromium, in trace amounts, helps regulate blood sugar levels, break-down of fats, and blood circulation. It may help prevent nearsightedness, which is a risk factor for vitreous degeneration, glaucoma and floaters.
Magnesium is one of the most abundant elements in the body. It is a mineral that reduces and prevents muscle spams. It relaxes the smooth muscles that regulate the circulation of aqueous humor within the eye.
Foods: Almonds, wheat germ, green leafy vegetables.
Selenium is an essential trace element that enhances the functioning of the antioxidant glutathione, supporting
healthy vision and overall health. It is also important in the functioning of the thyroid gland and in cells
using thyroid hormones (it may inhibit Hashimoto's disease).1
Foods: Nuts (especially Brazil nuts), whole grain cereals, mushrooms, meat, fish, eggs and some seafood. Also found in garlic, onions, broccoli, cabbage and sunflower seeds.
Zinc is not itself an antioxidant, but has some antioxidant characteristics. It helps heal injuries, supports
the immune system, and supports the functioning of many enzymes.
The AREDS study demonstrated that
it is helpful for macular degeneration.
Foods: Highest concentrations in red meat, oysters, crab and lobster. Vegetable sources depend on the soil quality, so organic products are probably the best: wheat germ, wheat bran, seeds (especially sunflower and pumpkin), beans, nuts (especially almonds), whole grains. Also, chicken, and turkey.

high fiber diets and phosphates in sodas absorption,
excessive coffee consumption,
some health conditions including liver or renal disease, and diabetes
Zinc restricts copper, so if you are taking zinc you should also take copper as well in a 15:1 zinc to copper ratio. Consult your health care professional.
