“Age-related cataracts”, now called “age-related cataracts”, can be prevented by: 1. Avoid strong ultraviolet light Strong light, especially ultraviolet light from the sun, is more damaging to the crystal. To avoid exposure to strong sunlight, a large-brimmed hat and a dark sunglass are needed.
2.Avoid body water shortage The lens inside the eye is undergoing constant metabolism, and water plays an important role in its metabolism and in keeping it transparent. The lack of water in the body of the elderly is one of the reasons for the clouding of the lens. Therefore, it is important to develop the habit of drinking more water, plain water and tea; it is better to eat more fruits, which replenish both water and vitamins. Pay special attention to replenish water when you have diarrhea, vomit, and sweat a lot.
3, replenish protein The cornea, lens and retina of the eye need protein and vitamin A. Lack of it will cause corneal lesions, cataracts, night blindness and other eye, gradually develop the habit of eating lean meat, fish, eggs, and more dairy and soy products; because the protein in this is rich and excellent quality.
4, make up enough vitamins Vitamin C can weaken the damage of light to the lens and has a role in preventing the formation of age-related cataracts. As people age, the vitamin C content in their eyes decreases significantly. It is also reported that lack of vitamin B2 can produce cataract. Vitamin C, vitamin B2, and even vitamin D have now been clinically administered frequently to patients with early cataracts. Foods rich in vitamin C include fresh vegetables and fruits. Foods rich in vitamin B include peanuts, beans, millet, animal offal, meat and eggs, fish, rice bran, peas, etc., while animal liver, eggs, milk, beans and fresh green leafy vegetables contain many vitamins.
5, trace elements such as zinc, cadmium, selenium, etc. are also involved in the synthesis of various substances within the eye, regulating its physiological functions can not be ignored. For example: cadmium deficiency affects the insulin regulation function, will make the blood sugar rise, causing the eye lens atrial fluid osmotic pressure rise, beef, coarse flour, mushrooms, grapes, etc. contains more cadmium. Foods rich in zinc include oysters, lean meat, etc.; foods containing more selenium include fish, poultry, cabbage, radish, garlic seedlings, etc.; foods containing more molybdenum radish, soybeans, lentils, etc.
6, aspirin Aging cataract patients tend to have elevated levels of some amino acids in their bodies, of which tryptophan and its metabolites combine with lens proteins to become brownish-yellow substances deposited in the crystal, forming cataracts. Aspirin, however, competes with tryptophan and binds to the lens protein, thus causing the level of tryptophan in the lens to decrease. It is generally taken orally within 100 mg per day, which does not cause gastrointestinal symptoms and can achieve the dual purpose of preventing cataracts and lowering blood viscosity.
In addition, we should avoid excessive fatigue of eyesight. We should use our eyes in such a way that they do not feel tired, and we should pay attention to the correct posture and distance of using eyes. In addition, you should avoid reading and working in a dark environment for a long time.
As long as you adhere to the above health care methods earlier in your daily life, you will keep away from senile cataract and avoid open surgery!
