Most of us will have macular degeneration as we age. But we can slow this process and even prevent it with certain dietary strategies. Learn how spinach and other foods and supplements can prevent the leading cause of blindness.
The macula in the center of the retina of our eyes can easily become damaged when it is unprotected. The macula can be damaged by looking into the sun or with prolonged bright light exposure. But the risk of this type of damage – or age-related macular degeneration – is decreased when the macula is protected by its own macular pigment.
When this macular pigment becomes thinner, it lets in a type of light that easily damages the macula. One of the most damaging is called blue light. Blue light is the prevalent emission among computers and many TVs. It is also a component of the sun – though the sun also has many healthy wavelengths of light that balance its blue light.
Yes, healthy macula maintains a yellow pigment that shields blue light. This might be compared to the macula having its own pair of sunglasses. This macular pigment is made up of three yellow carotenoids – specifically lutein, zeaxanthin and meso-zeaxanthin.
Towards the middle of the macula, zeaxanthin is more concentrated, reaching 75 percent. Away from the middle, the dominant component is lutein, with 65 percent or more of the total. Among all tissues, the macula contains the highest concentration of these carotenoids….
