7.Eggs
It’s a great package deal: The zinc in an egg will help your body use the lutein and zeaxanthin from its yolk. The yellow-orange color of these compounds blocks harmful blue light from damaging your retina. They help boost the amount of protective pigment in the macula, the part of your eye that controls central vision.
8.Squash
Your body can’t make lutein and zeaxanthin, but you can get them from squash all year long. Summer squash also has vitamin C and zinc. The winter kind will give you vitamins A and C as well as omega-3 fatty acids, too.
