Vitamin C supplementation can weaken the damage of light to lens and prevent the formation of senile cataract. B vitamins are important substances involved in the metabolism of nerve cells, including optic nerve, and have the function of protecting eyelids, conjunctiva, bulbar conjunctiva and cornea. When lacking or insufficient, the eyes are prone to dryness, conjunctival congestion, eyelid inflammation (bad eyes), photophobia, blurred vision, asthenopia, and even optic nerve inflammation. Foods rich in vitamin B include peanuts, beans, millet, animal offal, meat, eggs, fish, rice bran and peas.
Don't forget that trace elements such as zinc, cadmium and selenium are also involved in the synthesis of various substances in the eyes. Zinc deficiency affects the operation of vitamin A, causes the disorder of rhodopsin synthesis in retina and weakens dark adaptation. Foods rich in zinc include oysters and lean meat. When cadmium is insufficient, it affects the insulin regulation function and causes the osmotic pressure of aqueous humor to increase. The foods containing cadmium mainly include beef, coarse flour, mushrooms and grapes. Selenium participates in the activities of eyeball muscles and pupils and is an important element to maintain vision. Foods containing more selenium include fish, poultry, Chinese cabbage, radish and garlic seedlings.
Aspirin-assisted enteric-coated aspirin daily 100 mg can achieve the dual purposes of preventing and treating cataract and blood viscosity.
