Mom’s lesson to eat your greens was more valuable that you probably realized at the time. Green, leafy vegetables, such as kale and spinach, are good for eyesight and preventing age-related eye diseases, including cataracts and macular degeneration.
Greens contain cartenoids such as lutein and zeaxanthin, which promote vision and the health of the retina. There are 20 cartenoids found in human blood, but only lutein and zeaxanthin are found in the visual system. They are known to reduce disability from glare, enhance contrast and reduce photostress recovery times.
