Some vision loss is normal as we age. However, you can help preserve good vision and ward off cataracts, age-related macular degeneration (AMD) and vision problems by eating foods and taking supplements with three important nutrients.
Lutein and Zeaxanthin
Around the world more than 25 million people are affected by cataracts or AMD, which is the leading cause of blindness in people over the age of 55 in western society. Lutein and zeaxanthin are carotenoids that filter damaging high-energy blue wavelengths of light.
Cataracts are caused by oxidation of the lens in the eye making it cloudy. Lutein and zeaxanthin act like antioxidants in the eye, helping to neutralize the free radicals that cause cataracts and maintain healthy eye cells. Recent research even found that combining vitamin E with lutein and zeaxanthin decreased the risk of developing cataracts even more.
The human body does not synthesize these nutrients so we have to get them through our diet and supplements. The best sources are green leafy vegetables like:
- Green peas
- Green beans
This red pigment that comes from marine algae is getting a lot of buzz as one of nature’s most powerful antioxidants could be very beneficial for warding off vision problems.
Age, diabetes, glaucoma and other degenerative eye diseases affect millions of Americans each year. Other contributors to vision problems are exposure to ultraviolet radiation from the sun, inflammation and glycation (when sugar in the blood stream attaches to proteins forming harmful new molecules). Taking astaxanthin has shown to protect retinal cells, reduce oxidative stress and slow down advanced AMD. It also helps restore normal pressure in the eye when glaucoma has caused a dangerous billed up of fluid and pressure there.
Taking astaxanthin with lutein and zeaxanthin has been shown in research studies to improve visual acuity and contrast detection in people with early signs of AMD.
Seeing Is Believing
If you are over the age of 55, have a history of glaucoma or cataracts in your family, taking these three supplements could help you keep vision problems at bay. If you are already showing symptoms of AMD, cataracts or other vision problems, these three supplements in conjunction with prescription medications could help heal your sight.
