I read all of my monthly medical ophthalmic journals and from all of the
articles and research I have read I only feel a few hold merit in helping
vision/eye health. Omega 3 FA, zeaxanthin and lutein.
The later 2 listed are carotenoids. They are concentrated in the portion of
the retina called the macula which is where our 20/20 vision is located. The
foods that contain the highest concentration of them are yellow fruits and
vegetables and dark green leafy vegetables (highest in kale, spinach and collards
greens)
Here is a link to some more info about lutein and zeaxanthin
