There are many different elements that make up our eyes. One of these is the macula. This is part of the retina, which is found at the back of the eye. The macula contains a high concentration of light-sensitive cells. As they detect light that passes through the eyes, these cells send signals to the brain which then interprets them as images.
The macula contains three pigments. These are: lutein, zeaxanthin and meso-zeaxanthin. To preserve the health of the macula it’s necessary to maintain a deep layer of macular pigment. This will help to protect the cone cells from oxidative stress, keeping them healthy and functioning optimally for longer. The best way to achieve this is to find ways to replenish the macular pigment so that it remains thick and offers the greatest protection from the type of damage that characterizes eye diseases such as macular degeneration.
It’s true that lutein and zeaxanthin can be found in certain foods such as dark, leafy vegetables and citrus fruits, but you would need to consume large amounts to give the level of these nutrients an effective boost. Meanwhile, meso-zeaxanthin is much harder to increase through consumption alone. Fortunately, there is another option – supplements. Studies have shown that taking supplements that contain all three macular pigments can slow the progression of conditions like macular degeneration and keep vision optimized for longer.
