Alcohol consumption can have a range of negative effects on the eyes, and can even turn the white part of the eye yellow. This is known as alcoholic jaundice, and it occurs when the liver can no longer clear the build-up of old red blood cells from the body. This condition, called alcoholic hepatitis, is a sign of advanced alcohol use disorder. Other negative effects of alcohol on the eyes include blurred vision, double vision, dry eyes, and even blindness. These side effects can be both temporary and long-term, and can range in severity. The only proven way to prevent these issues is to seek addiction treatment.

What You'll Learn
Alcoholic hepatitis
One of the most noticeable signs of alcoholic hepatitis is jaundice, which causes the whites of the eyes and the skin to turn yellow. Jaundice occurs when there is an excess of bilirubin, a yellow pigment formed by the breakdown of red blood cells, in the bloodstream. This excess bilirubin deposits in the skin and eyes, resulting in a yellowish tint. While jaundice itself is not a disease, it indicates underlying health issues, particularly related to liver function.
The diagnosis of alcoholic hepatitis is primarily clinical and must include acute-onset jaundice, specific laboratory abnormalities, and a history of long-term heavy alcohol consumption. Ultrasound is the first imaging test used to assess patients with alcoholic hepatitis, and a liver biopsy may be performed to exclude other disorders. Treatment for alcoholic hepatitis includes stopping alcohol consumption, nutritional support, medications, therapy, support groups, and, in severe cases, a liver transplant.

Alcoholic eyes
Short-term effects
Intoxication can cause blurred vision, double vision, and difficulty adjusting to bright or dark lighting. Alcohol can also cause bloodshot eyes, as it relaxes and expands blood vessels, increasing blood flow. This can lead to redness and irritation, as well as puffiness around the eyes. Alcohol also affects how we perceive colours, and can increase sensitivity to light.
Long-term effects
Heavy alcohol consumption can lead to chronic dry eyes, blurred vision, and other eye conditions associated with sight loss. This includes cataracts, nystagmus, and age-related macular degeneration (AMD). Chronic alcohol abuse can also lead to optic neuropathy, which results in progressive vision loss. In extreme cases, excessive alcohol consumption can cause alcoholic hepatitis, which can lead to jaundice, causing the whites of the eyes to appear yellow.
Treatment
The only proven way to prevent alcoholic eyes and the effects of alcoholism is to seek addiction treatment. If you experience persistent eye problems or significant vision changes due to alcohol consumption, it is important to visit an eye care practitioner.

Alcohol's impact on vision
Alcohol is a toxin that affects the entire body, including the eyes. While moderate alcohol consumption does not cause long-term vision problems, heavy drinking can have several effects on the eyes and lead to long-term symptoms.
Short-term effects
The short-term effects of alcohol consumption on the eyes include:
- Blurred vision
- Double vision
- Dry eyes
- Bloodshot eyes
- Redness
- Puffiness
- Discomfort and irritation
- Stinging sensation
- Increased sensitivity to light
- Slowed pupil reaction to light
- Altered colour vision perception
- Slowed adjustment to bright or dark lighting
- Reduced visual acuity
- Lower contrast sensitivity
Long-term effects
Long-term heavy drinking can lead to or worsen several eye conditions associated with sight loss. The effects of alcohol on the eyes can be temporary or long-term, and they range in severity. Some of the long-term effects of alcohol consumption on the eyes include:
- Vision problems
- Nystagmus, a condition that shows as constant rapid involuntary eye movements
- Age-related macular degeneration (AMD), which can lead to loss of central vision
- Cataracts, a clouding of the lens of the eye, leading to blurred vision and eventually blindness
- Optic neuropathy, which results in progressive vision loss
- Blindness
Alcoholic hepatitis
In extreme cases, excessive alcohol consumption can cause alcoholic hepatitis, a form of alcoholic liver disease. Alcoholic hepatitis can cause the sclera (the white part of the eye) to turn yellow. This condition is also known as alcoholic jaundice and can be reversed if diagnosed early, the individual quits drinking, and receives appropriate medical care.

Treatment for alcohol-related eye issues
Alcohol consumption can have several adverse effects on the eyes, both short-term and long-term. Short-term effects include blurred vision and double vision, bloodshot eyes, and dry eyes. Long-term effects include progressive vision loss, optic neuropathy, and an increased risk of age-related macular degeneration (AMD) and cataracts.
The only proven way to prevent alcoholic eyes and the effects of alcoholism is to seek addiction treatment. Treatment for alcohol-related eye issues will depend on the severity of the condition and may include a combination of eye drops, lifestyle changes, and medical intervention for underlying liver issues.
Lifestyle Changes
- Staying hydrated: Alcohol is a diuretic, which means it increases the production of urine and can lead to dehydration. Staying hydrated can help counteract the dehydrating effects of alcohol and improve eye health.
- Eating a balanced diet: Alcohol can interfere with the absorption of nutrients essential for eye health, such as vitamin A. Adopting a balanced diet can help ensure the body receives the necessary nutrients for maintaining eye health.
- Reducing alcohol consumption: Cutting down on alcohol intake can help prevent further damage to the eyes and improve overall eye health.
Medical Intervention
- Eye drops: Lubricating eye drops can be prescribed to alleviate dry eye symptoms caused by alcohol consumption.
- Treatment for liver issues: Alcoholic eyes can be related to liver damage. Addressing underlying liver issues through medical treatment can help improve eye health.
- Treatment for vitamin deficiencies: Alcohol can interfere with the absorption of vitamins necessary for eye health, such as vitamin A. Medical professionals may recommend supplements or dietary changes to address vitamin deficiencies.
It is important to note that the treatment plan may vary depending on the specific eye condition caused by alcohol consumption. If you are experiencing persistent eye problems or significant vision changes due to alcohol consumption, it is advisable to consult an eye care practitioner or a healthcare professional for personalized advice and treatment options.

Alcohol's effect on the brain
Alcohol consumption can cause red eyes due to the dilation of blood vessels in the eyes. This is a common side effect of drinking alcohol, and it usually resolves itself within a few hours. When this happens, the capillaries near the surface of your eye become enlarged and more visible, giving them a reddish hue. Alcohol abuse can also lead to long-term damage, including vision problems, due to nutritional deficiencies and liver damage.
Alcohol affects the brain in several ways. Firstly, it alters brain chemistry by acting on neurotransmitters such as GABA and glutamate. GABA has a calming effect on the brain and body, and alcohol enhances this effect, leading to feelings of relaxation and reduced anxiety at low alcohol levels. In contrast, glutamate stimulates the brain and body, and alcohol diminishes its impact, resulting in decreased alertness. Additionally, alcohol interacts with the neurotransmitters responsible for releasing endorphins, often referred to as "pleasure hormones," leading to feelings of happiness and sociability.
During the early stages of drinking, the brain also releases more dopamine, a chemical associated with pleasure. This can result in feelings of euphoria, relaxation, and increased confidence. However, reasoning and memory may be slightly impaired during this stage. As alcohol consumption increases, different lobes of the brain are affected, leading to side effects such as blurred vision, slurred speech, and a lack of control.
Excessive drinking over an extended period can lead to mental health issues such as depression, anxiety, and an increased risk of suicide. It can also cause severe and potentially permanent brain damage. Recent studies have indicated that even moderate drinking may contribute to shrinkage in brain regions involved in cognition and learning, particularly the hippocampus, which is associated with memory and reasoning. This shrinkage has been observed to be proportional to the amount of alcohol consumed.
While occasional drinkers tend to recover once they are sober, chronic and heavy drinking can have lasting consequences. It can lead to physical symptoms such as tolerance to alcohol, where the brain becomes less responsive, requiring increased amounts or stronger alcohol to achieve the same effects. Alcohol dependence can also result in withdrawal symptoms, including anxiety, irritability, shakiness, and sweating, when abruptly reducing or stopping alcohol consumption.
