Excessive alcohol consumption affects eyesight and vision

Excessive alcohol consumption affects eyesight and visionShort-term effects of alcohol can impair and alter vision, but excessive alcohol can greatly impact eyesight and vision, leading to a condition referred to as toxic amblyopia. Aside from alcohol’s effects on vision and eyes, it has been long known that excessive alcohol can have lasting detrimental effects on the body as a whole.

The National Institute on Alcohol Abuse and Alcoholism reports that excessive drinking can lead to changes in the brain, heart, liver, pancreas, immune system, and even contribute to cancer. Years of alcohol consumption impairs many of the body’s functions resulting in organ failure. Thus, is it so important to limit or even cut out alcohol if necessary.

Excessive alcohol consumption also affects your eyesight


Excessive alcohol consumption also affects your eyesightExcessive alcohol consumption can have temporary and long-term effects on your vision. Temporary effects of excessive alcohol and eyesight result in blurry and distorted vision. But it is the long-term effects of excessive alcohol consumption you should be more concerned with.

As mentioned, the condition is referred to as toxic amblyopia, and it can lead to permanent vision loss and blindness.

If you only have a glass or two a night you probably don’t have to worry about your vision becoming permanently lost due to alcohol. But if you exceed the recommended guidelines of alcohol consumption and are often binge drinking, you could be putting your vision and eyesight in serious danger.

But why exactly is alcohol consumption a threat to your vision? Well, alcohol slows down the communication between neurotransmitters in the brain. Neurotransmitters are necessary for the brain to communicate with the rest of the body and vice versa. A delayed communication between the brain and the eyes causes the muscles in the eyes to weaken and lose coordination. This leads to double or distorted vision.

Excessive alcohol also slows down the reaction time of the pupils, meaning they cannot dilate and will constrict to allow in appropriate levels of light. In this situation, the ability to see colors and shades becomes impaired.

Other side effects of alcohol on your vision include:

  • Light sensitivity due to migraines
  • Red or bloodshot eyes due to alcohol and swelling blood vessels in the eyes
  • Rapid eye movement – involuntary eye movement
