7 Ways Excessive Drinking Can Cause Vision Problems

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. Another method to prevent blurry vision after drinking is to stay properly hydrated.

Blurry vision after consuming alcohol is a common complaint among some individuals. While it may be seen as a temporary side effect, there are cases where underlying medical conditions contribute to this issue. Understanding these conditions can shed light on why some people experience blurry vision after alcohol consumption. Alcohol is a substance that can have a profound impact on various organs and systems in the body, including the eyes.


It should be taken into consideration that some monocular cues contribute to obtaining information on relative distances and depth in the perceived scene, which seem to be sufficient to meet driving standards and drive safely. In fact, in the absence of binocular vision and stereopsis, driving under monocular viewing conditions is allowed in most countries14. Casares-López et al.34 demonstrated that other visual parameters such as contrast sensitivity and retinal straylight have an important impact on simulated driving after consuming alcohol34. However, they stated that the contribution of these two visual variables was limited (16.1%), indicating that other visual functions or psychomotor aspects may also influence driving ability after alcohol consumption. This limitation is also present in our study, although we have more completely analyzed binocular vision through different visual functions, and maintained a stable alcohol content of 0.40 mg/l. However, in further investigation it would be interesting to consider the effects of both visual and psychomotor aspects on driving under the influence of alcohol.

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.

Simulated driving performance

As a result, individuals with diabetes may experience blurry vision after consuming alcohol. Additionally, taking breaks between alcoholic beverages can help prevent or reduce the occurrence of blurry vision. Pacing oneself and allowing the body time to metabolize the alcohol can help mitigate the effects it has on the optic nerve.

In fact, for this parameter, alcohol consumption induced a statistically significant deterioration of 5.5 cpm, which agrees with our results which indicate weakness of binocular visual performance. We also observed a positive correlation between deterioration of binocular vision and impairment on simulated driving performance. In fact, this is the first study that correlates binocular visual deterioration including fusional reserves with simulated driving performance after consuming a moderate amount of alcohol. Our findings suggest that other binocular vision parameters could be considered for driving license tests such as stereoacuity and a complete vergence exam to ensure a safe binocular vision performance. Therefore, the present research shows the importance of a complete binocular vision exam in drivers to provide a more thorough assessment of the visual system.

Finding Treatment for Alcohol Addiction

This vision problem can also affect inebriated people however they may have had too much to drink to remember.

Patients who had been diagnosed with 2 other major sight-threatening eye diseases that can potentially cause severe VI, namely, exudative age-related macular degeneration and diabetic retinopathy, were also excluded. To ensure the accuracy of our recorded primary outcome, we excluded patients who already were severely visually impaired or blind before the second health examination date. Objective 
To evaluate the association between alcohol consumption status (and its changes) and risk of incident severe visual impairment (VI) or blindness in patients with newly diagnosed OAG. To minimize the risk of experiencing blurry vision after drinking, moderation is key.

Why Does Alcohol Blur Your Vision? Exploring The Causes Of Blurry Vision After A Night Of Drinking

Dehydration can cause the eyes to become dry and irritated, which can contribute to blurry vision. Additionally, alcohol can impair the function of the tear ducts, leading to inadequate lubrication of the eyes. This lack of moisture can exacerbate blurry vision and make it even more difficult to see clearly. When a person consumes alcohol, it is rapidly absorbed into the bloodstream and distributed throughout the body. The alcohol reaches the eyes through the blood vessels, affecting the delicate structures responsible for vision. One of the effects of alcohol on the eyes is that it can alter the function of the lens.

“Cutting out alcohol as part of Dry January will allow your body to reverse and put the brakes on many of the short and long-term effects of drinking. For example, after just 24 hours of no alcohol, your blood sugar levels will normalise and blurred vision caused by alcohol intake will disappear. However, we used a driving simulator because it represents an efficient, applicable, and safe device to assess driving performance8,9,32,50 in both natural and challenging conditions (such as under the influence alcohol). We excluded patients for whom values were missing from the health examination data.
