Three Kinds of Foods Harmful to Eyes
1, smoke
According to research, there are more than 750 chemical components in flue gas, including many toxic substances. Through animal experiments and observation of clinical patients, these toxic substances can directly affect the metabolic function of eye tissues, resulting in painless eyes, progressive vision loss and color vision disorder. Besides, according to the latest research, smoking can lead to amblyopia. Amblyopia caused by smoking is called tobacco toxic amblyopia, which is mainly manifested as decreased vision, narrowed vision and inability to distinguish between red and green. Therefore, not only do not smoke, but also stay away from the smoking environment.
2. wine
Drinking too much will also hurt your eyes. This is because after drinking a lot of alcohol, due to the role of alcohol, the whole body blood circulation is accelerated, which often makes the eyes bloodshot and damages the retina, thus resulting in "alcohol amblyopia." For patients with diabetes and hypertension, drinking alcohol can also lead to fundus bleeding, which leads to decreased vision and blindness. In addition, long-term heavy drinking will lead to the decline of digestion and absorption function, lack of B vitamins in the body, and cause conjunctivitis, optic neuritis and other diseases.
3. sugar
Sugar needs a lot of vitamin B 1 for metabolism in the body, which reduces the calcium content in the body. Lack of vitamin B 1 will aggravate the degree of myopia, while the decrease of calcium will weaken the elasticity of the ocular wall and promote the development of myopia, so eat less sugar.
