An occasional drink will not result in lasting damage to your eyes, but according to Your Sight Matters, “excessive drinking can cause permanent eye damage.” While we might commonly consider other parts of our body that alcohol can impact, like our liver, here’s how alcohol affects our eyes.
Your eye muscles
Alcohol will weaken your eye muscles. If you excessively use alcohol over time, your eye muscles could be permanently changed. Involuntary rapid eye movement could be a result of alcohol’s impact on your eyes. Also, since alcohol is affecting your eye muscles, your pupils are not working properly. This can lead to tunnel vision or your peripheral vision to be impaired.
Connection to brain function
If you experience double or blurry vision, or if you can’t decipher certain colors when you drink alcohol, it’s because the communication between your eyes and your brain is being impaired. Alcohol is slowing down your brain function and its ability to communicate with your eye muscles. Alcohol’s influence on your brain function is also decreasing your reaction time.
Sensitivity to light can be part of your hangover after consuming a lot of alcohol. Light sensitivity is usually accompanied by eye pain and headaches.
Another eye-related effect of drinking alcohol is bloodshot eyes. Alcohol dilates the blood vessels in your eyes making them appear larger and red.
There is also a condition called toxic amblyopia. It leads to permanent loss of vision or blindness, and it’s caused by a deficiency in nutrients. It’s also sometimes referred to as nutritional amblyopia. People struggling with alcoholism can be susceptible to this condition.
Please drink responsibly with your family and friends, and consider your health and the health of your eyes.
