How Does Alcohol Affect Vision and Eye Health?

The impacts of high alcohol consumption on your vision

BAC is expressed as a percentage in that 1% BAC means the individual has one alcohol molecule against 99 blood molecules. If you have any eye problems you worry may be related to drinking, talk to your eye doctor. They can do a comprehensive eye exam to look for signs of cataracts, macular degeneration and other problems. If you have AMD and are concerned about your alcohol intake, consider speaking with a doctor. Quitting alcohol completely can be difficult, but a doctor can help build a cessation plan that works for you. We think of our patients as family and have been leaders in eye care since 1981.

What is night blindness and what are the risks?

  • Alcoholic beverages such as beer, wine, and distilled spirits contain ethyl alcohol or ethanol.
  • Acute alcohol intoxication can also slow pupil reactions to changes in light, which can hinder someone’s vision in bright or dim environments.
  • Among them, alcohol teratogenicity and alcohol-related optic neuropathies are more definite and seem to be the most serious ocular conditions related to alcohol consumption [Table 3].

For non-normal data, the differences were analyzed using a Wilcoxon test, providing the degrees of freedom, the statistic (t and Z respectively), and the p-value. While there are many causes of eye twitching, it may be wise to cut back on drinking for a while if you develop an eye twitch that may be alcohol-related. Research suggests that drinking moderate to heavy amounts of alcohol may increase the risk of AMD development and progression. Some Problems From Heavy DrinkingDouble and distorted vision can occur from information that is slowed down between the eye and the brain. Decreasing the reaction time for the pupils to dilate, alcohol can impair the ability to see different color shades or adjust to lighting differences. ToleranceEveryone has a different tolerance for alcohol; you may be different from someone else who drinks the same amount.

  • While both genders are susceptible to the negative effects of alcohol on the eyes, the prevalence and risk factors may vary between the two.
  • A unit called blood alcohol concentration (BAC) outlines the amount of alcohol you take.
  • Over time, alcohol consumption can actually cause permanent damage to your brain cells and neurotransmitters, further weakening the eye muscles and distorting vision.
  • Population-based studies have shown a link between heavy alcohol consumption and an accelerated development of this disease.

For Healthy Eyes, Focus on Nutrient-Rich Food

These effects are typically temporary and subside as the alcohol is metabolized by the body. You may have had the experience of having too much to drink one night, maybe at a party or celebration; things begin to get blurry as the alcohol affects your brain and vision. This usually goes away after a short time and is temporary, along with a hangover and headache. Florida Eye Specialists and Cataract Institute would like you to gain some knowledge about eyes and alcohol and whether excessive drinking can lead to eye problems. A common side effect of drinking is dry eye disease or exacerbating the effects of pre-existing dry eye. This occurs when the eyes don’t produce enough tears, when the tears aren’t of the right hydration balance, or when they evaporate from the eye too quickly.

  • FAS increases the chances of unborn babies developing mental and physical defects such as eye diseases.
  • Alcohol is a diuretic that contributes to dehydration, light sensitivity, increased urine production, and reduced tear production.
  • However, for people with pre-existing eye conditions like glaucoma, the temporary rise in IOP may be more significant and potentially exacerbate their condition.
  • Regular heavy drinking can result in optic neuropathy, an eye condition that can lead to painless vision loss, decreased peripheral vision, or reduced color vision.
  • Regular alcohol use can cause permanent double or blurred vision while also impairing a person’s ability to perceive colors and light.
  • It has been suggested that men drink no more than 4 units per day and women drink no more than 3 units per day.

How Can I Minimize My Risk of Vision Problems?

This is in addition to the problems arising with other organs and the health of the whole body from excessive or long-term alcohol abuse. Your overall visual performance may be altered since drinking heavily impairs brain function. Your vision relies on a few different functions that your brain and eyes carry out, and alcohol impairs more than one of these functions. These are short-term effects that can begin while you are drinking, and can last for several hours afterward. 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.

Changes in Visual Performance under the Effects of Moderate–High Alcohol Consumption: The Influence of Biological Sex

Furthermore, a study on eye color and alcohol dependency found a statistically significant connection between blue eye color and alcohol dependency in individuals of European ancestry. These findings provide evidence of a genetic contribution to the risk for alcohol dependency that is related to eye color. Whether you consider yourself a “social drinker” or have struggled with alcohol misuse or addiction, consuming any amount of alcohol consistently over time can have negative physical and psychological consequences. Among its short-term effects are blurred vision and double vision, which can be temporary effects of intoxication, although they typically wear off as the person sobers up or the next day. Alcohol abuse can also contribute to long-term changes to vision such as an increased risk of developing cataracts.

However, dehydration from excessive consumption might exacerbate the perception of floater and make the vitreous more noticeable. Individuals who consume alcohol are more likely to develop AMD that progressively gets worse leading to blindness in some cases.
