Carrots are famous for their beta-carotene when in fact they contain all the carotenoids
When cut open they resemble the pupil & iris of they eye with the radiating lines. The green carrot tops look like the dendrites & visual cortex of the brain.
Eating two medium sized carrots every day, preferably as the sun is going down, will increase blood flow to the eyes by 25% in 7 days and up to 50% in 14 days.
This can prevent or clear cataracts (blockages of the lens at the front of the eye), and glaucoma (blockages of the canals at the back of the eye) as well as improving vision.
