In addition the lens in the eyes are an intravital structure soaked in water of the room too, carry on constant supersession, circulate the intersection of room and water of interest in supersession their and keep, play an important role in the transparent course. Lack water in the old human body, it is one of the reasons causing the crystal to thicken. So no matter the old and the young should all get used to drinking the water more, plain boiled water, tea, beverage will do; Pay attention to preventing suffering from diarrhoea, vomiting, sweating in a large amount, cause dehydration; Avoid seeing the screen for a long time and reading at short range, cause the eyes to be dry because of staring at. Don't always rub eyes when the eyes are dry, but should close eyes and have a rest or see a doctor. Make eyes get appropriate maintenance and moist, it is astringent and uncomfortable that can improve the eye and do.

The content of vitamin C is 30 times higher than in the blood to fill vitamin C in the human eye. Increase with age, the content of vitamin C obviously drops, the lens are malnutritive, will cause the lens to change the sex as time passes; Oxygen that vitamin C can weaken the light has function of preventing old cataract from forming on the damage of the lens. Vitamin C is abundant in natural vegetables, fruit. The thick liquid machine of the self-provided home fruit, make fresh fruit juice to drink better, has already supplemented the moisture, have supplemented vitamins. B clan vitamin is the important material which participates in the neural cellular metabolism including optic nerve, and there is function of protecting the eyelid, conjunctiva and cornea. When being scarce insufficient, apt to make eyes do astringent, the intersection of ball and the intersection of conjunctiva and congest, the intersection of eyelid and inflammation (by bad eyes) , photophobic, eyesight is fuzzy, eyesight is tired, even optic nerve inflammation takes place. The food with abundant B clan vitamin is peanut, beans, millet, animal's viscera, meat, eggs, fish, rice bran, pea,etc.. Vitamin B12 production of the peripheral myelin of nerve fibre is extremely important. Natural the intersection of vitamin and B12 can only get from animal food, so how the whole vegetarian need edible soya-bean milk type or supplement vitamin B12 extraly. Don't forget microelement such as zinc, cadmium, molybdenum, selenium,etc. participates in eyes various materials are formated, regulate its physiological function, can't ignore. Lack the operation that zinc influenced vitamin A, will cause retinal visual purple to formate the obstacle, dark adaptation is weakened. The food with abundant zinc is oyster, red meat,etc.; When cadmium is insufficient, influence the insulinogenic regulating function, will make blood glucose rise, cause water of eyeball lens room to permeate and press to rise, the diopter increases and causes near-sightedly. The food with abundant cadmium is beef, thick flour, mushroom, grape,etc.; Selenium participates in the activities of eyeball muscles, the pupil, maintain visual an important element. Take in selenium and is lower than 50 milligrams every day, eyesight will be influenced some time later. Includes selenium more food and is fish, poultry, pakchoi, turnip, garlic bolt,etc.; Molybdenum is the important nutrient component which makes up eyes iris. Includes molybdenum more food and is turnip, soybean, French beans,etc.. Careful to have, defend old function of cataract with the intersection of medicine and aspirin, senile cataract patient the intersection of amino acid and competence rise often in the body, tryptophane can in combination with plasma protein amino acid among them. Tryptophane and supersession product are bound with lens albumen and turned into a pale brown material to deposit in the crystal, form cataract. And aspirin competes with tryptophane, prevent it from binding with crystal albumen, thus make tryptophane level in the crystal drop. Take the water dosage enterically and dissolve aspirin, it is less than 100 milligrams every day, will not already cause intestines and stomach symptom, can achieve and prevent cataract and viscous purpose to hit two hawks with one arrow of the blood. The person prone to glaucoma avoids using mydriatic of Atto's category, so as not to influence the water circulation of eyes; Having used the medicines of some hormone sometimes, the bloated feeling of headache eyes appear, that may be omen of glaucoma too. Avoiding strong light ultraviolet strong light especially sunlight ultraviolet ray will damage heavier to the crystal, shine time the longer, it is the greater to suffer from the possibility of cataract. While being out, especially while travelling, swimming, should wear large eaves cap and dark sunglasses to cover the ultraviolet ray. The elderly wear the sunglasses, it is not for following the fashion. Certainly the dim light is unfavorable too to eyes, regard appropriate as good. Prevent oxygen deficiency from finding in the research of diabetes, because of getting the normal nutrition needed in recent years, the eye tissue was often in a kind of oxygen deficiency " The hunger state " ,The transparent lens become muddy and unclear gradually, like being stopped by a floor of white membrane, see things clearly, call " the diabetic cataract " as at the medical science . Oxygen deficiency, will impel iris and front room corner (water of the room flows out the mouth) Stop up, hinder from the intersection of room and water list in the eyes, intraocular pressure increase thereupon, form " continue taking place glaucoma " ; Diabetic oxygen deficiency also will make retina appear the intersection of hair and detailed hemangioma, new born blood vessel and ooze out thing, namely diabetes and retinal pathological change. So, the person with diabetes should treat diabetes, a series of eyes disease preventing oxygen deficiency from causing actively.
