Lutein and zeaxanthin supplements help protect against macular degeneration and cataracts and improve vision. Flavonoid-rich extracts of blueberry, bilberry, pine bark, or grape seed are also beneficial. Beta-carotene, vitamins C and E, zinc, copper, selenium and Omega-3 fatty acids also help prevent eye problems.
Nutritional factors play a key role in the prevention and treatment of cataracts and macular degeneration. A diet high in richly colored fruits and vegetables—as well as targeted supplements—is associated with a lowered risk of both conditions.
What Are The Primary Nutrients Required?
Lutein And Zeaxanthin
In patients with macular degeneration, 10–15 mg of lutein daily led to improvements, including glare recovery, contrast sensitivity, and visual acuity, as compared to a placebo group.
Research shows that lutein and zeaxanthin supplements not only help protect against macular degeneration but also improve visual function in people with macular degeneration. Like the macula, the human lens concentrates lutein and zeaxanthin. In fact, these are the only carotenes found in the human lens.
Lutein is also important in preventing cataracts and improving visual function in people with existing cataracts. Studies have shown that the intake of lutein is inversely associated with cataract surgery.1
Take 150–300 mg of one of these extracts every day to support eye health.
Something as simple as taking vitamin C or zinc supplements can produce dramatic effects. You can start by taking 300 mg of vitamin C every day to prevent cataract development.
In a study, women who took vitamin C for more than 10 years had a 77 percent lower rate of cataract formation compared to women who did not take the vitamin. Zinc also plays an essential role in the metabolism of the retina and the visual process.2 A two-year trial involving 151 subjects showed that the group taking zinc had significantly less visual loss than the placebo group.
CoQ10 And Acetyl-L-Carnitine
In one double-blind study, 200 mg of acetyl-L-carnitine, omega-3 fatty acids (460 mg EPA and 320 mg DHA), and 20 mg of CoQ10 was shown to improve visual function and macular alterations in early-stage macular degeneration. This combination stopped the disease from progressing in 47 out of 48 cases.
There is a strong relationship between atherosclerosis (known as hardening of the arteries) and eye health.
The recommended dosage is 1,000 mg of EPA and DHA.
Foods Rich In These Nutrients

- Bell peppers
- Collard greens
- Sweet potatoes

Gee Lance, your vocation should have been a Doctor with all the information you get. Maybe when the windmill thing drys up you could open some sort of information centre for people to try better medical procedures and save money and their health
Smoking and obesity contribute to increased risk of MD. Healthier lifestyles help prevent many age related maladies.
My daughter is only 19 years old and has the beginning of cataracts, she was devastated when she found out two years ago and now at night her eyes hurt because of lights, she is trying to be strong, she doesn't even complain. Even later down the line with surgery, she would have to wear reading glasses for the rest of her life, as she wouldn't be able to read at all without
Thanks for the info Tammy,what I have is AION,its a rare eye disease caused from a stroke to the eye,not the same as a stoke involving the heart tho,it damages the optic nerve and at this time they have no fix for it,we have like 1.2 million nerves in the optic nerve and they are so small they have no way of repairing them,hopefully in the future they will figure something out but for now nothing.I could loose the vision in my right eye within the next 3 years but I have a very good nuerological eye specialist who took me on as a patient in Peoria and he's very highly respected and I love him,he's great and going everything possible to help prevent my right eye from going blind also,as of now I have about 20-30 % vision in my right eye but the left is completely gone,I just pray I can keep what i do have left for a long time bit no guarantees.
