How Alcohol Affects Your Eyes

There may be an association between increased alcohol consumption and geographic atrophy, a form of advanced age-related macular degeneration (AMD). However, simply reducing alcohol intake may not be enough to prevent geographic atrophy. In addition, alcohol has been proven to alter the ability to perceive contrast. Researchers in Australia found that consuming alcohol at their legal limit of 0.05% greatly affected the ability to visually adjust for brightness and contrast. The perception of contrast was reduced by 30% at the legal blood alcohol level.

Eye diseases such as glaucoma and macular degeneration have no cure. Doctors work to catch the conditions in their early stages to slow or prevent vision loss. This dehydration leaves you with dry eyes because you lack the fluid necessary for tears that hydrate your eyeballs.

Moderate drinkers of red wine seemed to have a decreased risk of cataract formation and age-related macular degeneration. The conclusions suggested that the results came from the antioxidants in red wine, and further animal trials supported the idea. Various alcohol blurry vision studies have classified alcohol consumption differently. In this review, the concept of heavy drinking will be clarified through both quantitative and qualitative descriptions of daily alcohol consumption based on moderate or heavy alcohol abuse.

  • Resveratrol finds its highest concentration in red wine, though it also exists in white wine.
  • A common form is wine, which is a staple for many Americans during their evening meal.
  • It’s why people who have had a stressful day might tell themselves that they would like to have a drink to help them unwind.
  • Continually excessive alcohol consumption increases the risk of age-related cataract formation, with the illness displaying in individuals as young as 40.

Poor diet and over-consumption of alcohol may also be related to developing cataracts. Red wine is one of the most commonly reported migraine triggers, but researchers have yet to understand exactly what it is about red wine that causes headaches. This is what happens in our bodies as the neurotransmitters that have been suppressed by alcohol try to fight their way back into our systems in an abrupt manner. As the body begins to detox and the neurotransmitter systems try to stabilize GABA (gamma-aminobutyric acid) and glutamate back into the system, this is what sends people into withdrawal.

How Much Can A Person Drink Safely?

Experts received confirmation of their worst fears when thousands suffered blindness or paralysis after drinking the spirit. No reliable sourcing indicates how many people experience vision issues due to alcohol. Law enforcement officers assess several alcohol-induced changes to the eyes when performing a field sobriety test on a suspected impaired driver.

Once a person quits drinking, after the body has been used to working so hard against it, naturally as in a game of tug of war when one side lets go, it sends the other side rapidly backwards. Understanding your symptoms and signs and educating yourself about health conditions are also a part of living your healthiest life. The links above will provide you with more detailed information on these medical conditions to help you inform yourself about the causes and available treatments for these conditions.


However, change in visual functions have always been focused in ethanol intoxications. When a person’s blood alcohol content (BAC) begins to rise, they begin experiencing the effects of intoxication. There are many ways in which binge drinking and drinking in excess affects vision.

  • It is important to determine the cause of any vision changes; your eye doctor can treat them or send you to a specialist for further diagnosis or treatment.
  • Studies have shown that vision loss can be a result of a nutritional deficiency, and some professionals believe that the condition develops because of the toxic effects of alcohol and tobacco.
  • A nutritious diet ensures you have the essential nutrients for healthy eyes.
  • As alcohol slows the central nervous system, it also reduces the reactions of the pupils.
  • Both of these can lead to the development of nutritional optic neuropathy over time.
  • The shed pounds can further assist with lowering your blood pressure.

You need to be aware of how much alcohol you can handle and make sure you stay within that limit. You should also monitor how often you drink to your own personal limit (or over it). By taking these steps, you can still enjoy the social effects of alcohol while protecting your eyes. Even when you have just a few drinks, your eyes do not function as well as when you are sober. Drinking just one drink can cause you to get dizzy or have blurry vision.
