The most prevalent side effect of heavy drinking is double vision or fuzzy vision. Because alcohol is a depressive, it slows response times and impairs coordination, this occurs as a result of reduced eye muscle coordination. When intoxicated, an individual will often walk in place to stay warm, which can lead to blurry vision. This is because the blood flow is being directed toward maintaining body temperature, rather than supplying the brain with vital oxygen. The long-term effects of alcohol on the eyes are not known but research does indicate that excessive drinking can be harmful to vision. Drinking too much can also cause blackouts due to decreased activity in the part of the brain that controls movement. During these periods, the person feels as if they were floating away from reality. When sobering up, the person may not remember anything from this time period. Finally, heavy drinking can lead to dry mouth, headache, irritability, and loss of appetite. These are all signs that something is wrong and you should seek help before further damage occurs. Double vision is only one of many problems that can occur when drinking too much. If you are experiencing any other symptoms such as confusion, memory issues, difficulty walking or driving, then stop drinking now! Visit a medical facility for evaluation by a physician.
