    Drinking alcohol heavily wil impairs brain function and weaken your eye muscle coordination. So you may get blurred vision or double vision after you drink alcohol. Drinking alcohol will also slow pupil reactions and make peripheral vision decreased. So people who drink alcohol are not suitable for driving.

    Alcohol won't hurt your eyesight, but if you drink them heavily, it will affect your optic nerve. So you are unable to focus on objects well. To keep your eyes healthy, you'd better drink less alcohol.

    Yes, definitely alcohol could affect the eyesight. We all know that too much alcohol is bad for health, but what side effects does alcohol bring to eyes? Alcohol could impact our vision in various ways. It could reduce the vision acuity up to 32% so that our vision is blurry always after drinking alcohol. It impact our peripheral vision, giving drunk people a tunnel vision. As to depth perception, alcohol decreased the ability to judge distance and depth, so it is very difficult for drunk people to have both eyes focus on the same object. This also explains why some people complained that they have eyes crossed when they are drunk, because the alcohol weakens muscles controlling ability. It slow down our reaction to glare so the vision clarity is impaired. Too much tobacco or alcohol would bring optic neuropathy to impair the general vision. Finally we all know that alcohol brings extra burden to liver. While liver is responsible for converting beta-carotene into vitamin A which is important to eye health, So alcohol damages liver and therefore damages vision.
