How Does Alcohol Affect Vision and Eyesight?
Alcohol tends to affect the speed at which your iris constricts and dilates. A driver that has been drinking alcohol cannot adapt as quickly to oncoming headlights. A large longitudinal study published in 2021 similarly showed a link between low to moderate wine drinking and a lower risk of developing cataracts that required surgery.
Chronic consumption of alcohol leads to impairment in the visual field of your eye, causing decreased peripheral vision. Dry eyes, which occur during excessive alcohol consumption, can become chronic discomfort and blurry vision. Long-term drinking of alcohol increases the risk of developing cataracts early in life. Alcohol consumption impacts your normal body functioning in many ways.
Consuming alcohol may increase dehydration, promote inflammation, and disrupt vitamin transport — all factors that can negatively affect tear quality and quantity. Your dry eye symptoms may persist if you stop drinking or experience alcohol withdrawal. Drinking alcohol when you’re already experiencing dry eye for other reasons can add the effects of alcohol to your existing symptoms. If you already live with a dry eye diagnosis, drinking alcohol may make your symptoms worse. Alcohol may also affect your eyesight in the long term, going beyond temporary symptoms to influencing your likelihood to develop serious eye conditions.
- There may be an association between increased alcohol consumption and geographic atrophy, a form of advanced age-related macular degeneration (AMD).
- It is hard to predict whether you will develop effects that harm your liver, heart, nerves, or eyes, and you can experience a combination of these.
- Alcohol affects the central nervous system, including the optic nerves, which can lead to temporary blurred vision.
- Conditions such as alcoholic optic neuropathy and cataracts can develop over time and cause irreversible damage to the eyes.
- In some cases, methanol poisoning can occur as a result of drinking homemade alcohol or moonshine.
Your muscles might not move as effectively while you are under the influence of alcohol. When this happens, you may have blurred vision or double vision due to weakened eye-muscle coordination. One or both of your eyes may twitch during or after drinking alcohol. 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. While double vision from drinking is a temporary effect, this is just one of the reasons that drinking and driving can be so dangerous.
Bloodshot Eyes
It is important to prioritize one’s health and well-being when consuming alcohol to minimize any potential negative effects on vision. Another method to prevent blurry vision after drinking is to stay properly hydrated. Alcohol is a diuretic, meaning it promotes fluid loss and can cause dehydration. Dehydration can have several negative effects on the body, including dry eyes and blurry vision.
Understanding these conditions can shed light on why some people experience blurry vision after alcohol consumption. One of the most effective ways to prevent or reduce blurry vision after drinking is to consume alcohol in moderation. Drinking in moderation means limiting the amount of alcohol you consume in a single sitting. This can help prevent the drastic impairment of the optic nerve and minimize the occurrence of blurry vision. The Centers for Disease Control and Prevention (CDC) defines moderate drinking as up to one drink per day for women and up to two drinks per day for men. It is essential to understand that the occasional instance of blurry vision after drinking alcohol is likely temporary and not a cause for concern.
Whether you consume just a couple of drinks or involve yourself in heavy drinking, alcohol can affect your vision and eye health. A lot of people consume alcohol for the sake of having a good time and enjoying themselves. Occasionally drinking moderate amounts of alcohol doesn’t usually cause any health problems. But if you are a heavy drinker—which means consuming alcohol more than a few times per week or binge drinking—you will likely experience health issues as a result. It is hard to predict whether you will develop effects that harm your liver, heart, nerves, or eyes, and you can experience a combination of these.
This vision problem can lead to lots and lots of headaches, especially during the sobering-up stage. Expect slow pupil reaction time for up to 24 hours after your bout of excessive drinking. If someone is suspected to have nystagmus, they will likely undergo a CT scan or an MRI to get a scan of the brain. Often these rapid eye movements are due to neurological problems in the brain. Optic nerve damage brought on by alcohol will sometimes lead to a condition called toxic amblyopia.
Alcohol’s long-term effects on your eyes and vision
It is also advisable to avoid consuming alcohol on an empty stomach and to take breaks between drinks. If blurry vision persists or worsens after drinking, it is important to seek medical attention. Moreover, it is essential to prioritize eye health and ensure that any pre-existing conditions are properly managed. Individuals with underlying eye conditions, such as astigmatism or dry eye syndrome, may be more prone to experiencing blurry vision after drinking. By routinely visiting an eye doctor and following their recommendations for managing these conditions, individuals can minimize the impact that alcohol has on their vision.
To counteract this, it is important to drink water before, during, and after consuming alcohol. This will ensure that the body remains properly hydrated and decrease the likelihood of experiencing blurry vision. It is important to note, however, that excessive alcohol consumption can have long-lasting effects on vision. Chronic alcohol abuse can lead to various vision-related problems, such as optic neuropathy and alcoholic amblyopia. Optic neuropathy is a condition in which the optic nerve, responsible for transmitting visual information from the eye to the brain, becomes damaged. While occasional blurry vision after drinking is usually temporary and harmless, excessive and long-term alcohol consumption can lead to serious vision problems.
Next time you go out drinking or have a get-together, set a limit for yourself so as to not go overboard. Optic nerve damage is very closely linked to neurological damage sustained by the brain when partaking in heavy drinking. Because the optic nerve is made up of neurological transmitters, it can become damaged by alcohol, just like in the brain. Sure, we know that drinking affects our vision and can cause blurred or double vision, especially at night.

This article describes the potential effects of alcohol on your eyes. The alcohol-induced blurry vision typically occurs because the eye muscles responsible for focusing become less coordinated. This effect usually subsides once the alcohol is metabolized and its effects wear off.
Short-term effects of alcohol on the eyes and sight
A Journal of Ophthalmology study found that night vision gets worse after drinking in both men and women. The more alcohol the subjects drank, the worse their vision became under low-light conditions. They saw halos and starbursts, had difficulty seeing contrast, and experienced longer recovery time after a bright light was shined in their eyes. A person may reduce their risk of developing vision issues due to alcohol by limiting their alcohol consumption. Even small changes can help reduce a person’s risk of developing issues with their eyes or other aspects of health.
See your eye doctor
Your overall responses can slow down while you are under the influence of alcohol. This means that it can take a little longer than usual for your brain to recognize what you are seeing, and it can take longer than usual for you to decide what to do about it. Drinking alcohol may decrease the sensitivity of your peripheral vision.
The number of drinks it takes to get to that level varies based on sex, weight and other factors. For example, it may only take two drinks in an hour for a 100-pound woman to experience blurred vision or up to five drinks in an hour for a 240-pound man. The potential long-term issues relate to changes to the eyes’ structures or the communication between the eyes and brain. These effects may be more permanent and can include reduced vision, migraine headaches, sensitivity to light, and even blindness.
