Factors associated with macular degeneration

February 2nd, 2010

Age-related macular degeneration is the leading cause of blindness among people over 50 years old in industrialized countries. Scientists have found that antioxidants such as carotenoids are helpful in decreasing the risk of AMD. In particular, spinach is one of the best sources of carotenoids, which are considered as normal macular protective pigment (MPP).

UV rays have been long reported to damage eye tissues because they produce free radicals in the eye. What’s more, blue light is particularly harmful to the macula which is the central retina. A common way to fight against these harmful rays is to wear sunglasses with HEV and UV protection. And brown or amber sunglasses are believed to block out HEV most effectively.

In addition to sunglasses, experts also recommend some nutrients for AMD prevention. Zeaxanthin and lutein are two of the powerful antioxidants that have been found in the macular tissue of the retina. Both of the two nutrients protect the photoreceptors against oxidative stress, inflammation and even degeneration.

There are many sources of zeaxanthin, including foods and supplements. Those foods include egg yolks, squash, pumpkin, orange peppers, collard greens, tangerines, romaine lettuce, green beans, spinach and so on. In addition, supplements from various brands such as Eye Promise-Restore are helpful for those who can not get adequate amounts of zeaxanthin from a diet.

Omega-3 fatty acids are also thought to help maintain eye health. The most common way is to consume fish oil extracted from cold water fish such as salmon, mackerel, anchovies as well as sardines. Ordinary people are encouraged to contain certain amount of fish oil in the diet.

Glutathione is an intracellular antioxidant. It can literally prevent degeneration in the delicate photoreceptor cells. This type of antioxidant is a billion more times potent than Vitamin C in neutralizing those free radicals in the eye.

One’s lifestyle is also critical. Obesity and smoking are both thought to increase the risk of severe macular degeneration by 4 times. And regular exercises are usually helpful in maintaining a health life.
