Clinical observation shows that amblyopia caused by smoking and drinking is increasing. According to the statistics of an eye clinic in a big hospital, the patients with toxic amblyopia caused by alcohol and tobacco have accounted for 5.3% of the number of eye clinics, and there is a trend of increasing year by year.
The smoke produced by smoking not only directly irritates the conjunctiva and cornea of the eyes, but also causes congestion, tears, carbuncle and blurred vision, and also inhales nicotine, cyanide and nicotine. In vivo, it can damage the retina and optic nerve of the eye, cause spasmodic contraction of small blood vessels in the fundus, and affect vision.
Alcohol in wine can easily stimulate the optic nerve and reduce its conduction function and sensitivity. When the retina is stimulated by alcohol, congestion and edema will occur, which often causes visual distortion. In addition, drinking too much easily hinders the absorption and utilization of various vitamins, but increases the consumption and excretion of vitamins. Vitamin A is a nutrient that retina needs all the time. Without vitamin a, vision will be obviously reduced. Some people are very sensitive to alcohol, and although they don't drink much, they will also have adverse reactions. Especially those suffering from conjunctivitis, trachoma, iritis, keratitis, myopia and strabismus.
Drinking varies from person to person, which often aggravates the illness.
