Dark green vegetables can prevent cataract
Experts say powerful antioxidants can protect against the cumulative effects of oxidative damage, protect the eyes from the sun's ultraviolet rays, and thus prevent cataracts.
In particular, lutein and zeaxanthin have a strong antioxidant effect. They can absorb harmful light into the eyeball, prevent eye aging, delay vision loss, and achieve the best lens protection effect.
Lutein and zeaxanthin are common in dark green vegetables, including spinach, green pepper, green cauliflower, mustard and so on, which are rich in lutein and zeaxanthin. Another antioxidant is vitamin C.
Vitamin C has been recognized to be able to protect the protein and other components in the lens of the eye. Vitamin C can help collagen strengthen the strength of microvessels, so as to nourish the retina and avoid UV damage. Studies have shown that vitamin C is high in the lens of healthy eyes, but much less in the lens of cataract patients.
