It can cut down on your peripheral vision as well, resulting in tunnel vision. Prescription drugs often have side effects that threaten vision and eye health. Low to moderate alcohol consumption may prevent some eye diseases such as central retinal vein occlusion (RVO), the blockage of eye veins. Heavy drinkers who smoke and have poor dietary lifestyles are also likely to develop alcoholic amblyopia, a rare case of bilateral vision loss. At 0.15% to 0.19% BAC, motor functions, balance, and vision are impaired.

Dr. Yong aims to expand access to affordable eyewear and improve eye health worldwide. There is no single treatment, so individuals receive treatment depending on their symptoms. Researchers have noticed that heavy drinkers are likelier to have low levels of protective nutrients such as zinc and vitamins (B12 and folate). Studies showed that alcohol reduced vision in low-illumination environments, especially at night. To understand the effects of alcohol on our vision, you must first understand different blood alcohol levels.
At 0.20% and above, individuals are severely intoxicated and may experience loss of consciousness. In extreme cases, some slip into a coma and even die due to respiratory failure. At 0.05% to 0.07% BAC, individuals feel ‘tipsy.’ Then at 0.08% to 0.09%, individuals experience reductions in physical coordination and should not drive. At 0.10% to 0.14%, individuals experience a loss of coordination and judgment. Consuming alcohol may increase dehydration, promote inflammation, and disrupt vitamin transport — all factors that can negatively affect tear quality and quantity.
Alcohol affects the functioning of the eye by slowing down the transmission of signals between the eye and the brain. This can result in a delay in how quickly the eye can focus on objects, leading to blurry or double vision. Additionally, alcohol can also cause blood vessels in the eyes to dilate, which can further contribute to visual disturbances. Alcohol consumption has a range of effects on your vision, from temporary impairments to long-term health consequences. Understanding these effects can help you make better choices regarding alcohol use and take steps to protect your eye health. By drinking in moderation and taking care of your eyes, you can enjoy a healthier, clearer vision for years to come.
Alcohol and Eye Health: The Effect of Alcohol on Vision
ModerationWhen enjoyed in moderation, alcohol will not damage your eyesight on a permanent basis. There should be no long-term problems; short-term problems, however, such as blurred vision or headaches are common from overindulgence. Long-term abuse of alcohol can also lead to toxic amblyopia or vision loss. Both short-term and long-term use of alcohol affects the optic nerve and the relationship between the brain and the eye.
However, in the short-term, even one drink can have negative effects on the eyes (e.g., dry eyes). In addition to the short-term and temporary effects of alcohol, consuming heavy amounts of alcohol can lead to irreversible eye problems over time. You might develop a painless loss of vision, decreased peripheral vision, or reduced color vision.
Excessive alcohol consumption increases the risk of Substance Use and Co-Occurring Mental Disorders National Institute of Mental Health NIMH developing cataracts. That’s a common eye condition where the eye’s lens becomes cloudy and obscures vision. Cataracts are relatively more common in heavy drinkers than in moderate or non-drinkers. Heavy drinking also significantly increases your risk of heart and liver problems. Though these aren’t eye diseases, the first signs of these conditions are often seen in the eyes as part of a comprehensive eye exam. Signs of heart disease include optic neuropathy, atrophy, bleeding in the retina from vascular occlusions, and even hypertensive retinopathy.
- Furthermore, ensuring adequate hydration while drinking alcohol can help counteract some of the dehydrating effects that contribute to blurry vision.
- This increased sensitivity is a direct result of alcohol’s effect on the pupils and how they react to changes in light.
- Swelling of the blood vessels in the eye or the look of red bloodshot eyes is a common feature of those who have been lifetime drinkers.
- Nystagmus may sometimes cause you to lose balance or to have trouble balancing yourself while standing for long periods of time.
- Alcohol causes the blood vessels in your eyes to dilate, making them look red and sometimes feel uncomfortably itchy.
Health Challenges
Firstly, alcohol is a vasodilator, meaning it widens the blood vessels throughout the body. This includes the blood vessels in the eyes, which can lead to increased pressure within the eyes and alterations in the eye’s ability to focus properly. Additionally, alcohol can affect the production and balance of neurotransmitters in the brain, which play a crucial role in regulating vision and eye movement.
It also urges people to be wary of homemade brews, and free drinks or drinks priced far below normal.

However, simply reducing alcohol intake may not be enough to prevent geographic atrophy. Drinking large amounts of alcohol may temporarily but significantly increase the size of your pupils, though effects can vary from person to person. When you drink alcohol, your vision may change in various ways during and shortly after drinking. For example, researchers found that people who have been drinking are likely to rate images as more attractive, widely known as the “beer goggles” effect.
