Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have symptoms of double vision after drinking alcohol and feeling of dizziness which is mainly because of drinking a bit more than normal over a long period of time damages the brain and impairs its ability to function. Because of this eyesight is also affected negatively. You can get decreased peripheral vision and migraine attacks as well, these impairments are caused by the weakening of the muscles in the eye. Having impaired eyesight in this way can also decrease your reaction time. Alcohol will cause optic neuropathy as well. I would suggest you to avoid drinking excess of alcohol. If ever you take alcohol drink it with plenty of salads. Drink alot water along with alcohol and eat probiotics such as yogurt. Visit ophthalmologist once and get eyes examined properly and start with antibacterial eye drops for better vision. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
