Drunk Eyes

Understanding Drunk Eyes: Causes, Symptoms, and Implications

Drunk eyes, colloquially referred to as “beer goggles,” describe the physical changes in a person’s eyesight when under the influence of alcohol. This phenomenon has attracted significant attention due to its potential impact on perception and decision-making. In this essay, we will explore the causes, symptoms, and implications of them, shedding light on this intriguing yet consequential aspect of alcohol consumption.


Drunk eyes primarily result from the effects of alcohol on the central nervous system and the eye muscles. When alcohol enters the bloodstream, it affects the brain’s neurotransmitters, altering the normal functioning of the visual system. Additionally, alcohol can cause blood vessels to dilate, including those in the eyes, which further contributes to changes in vision.


  1. Blurred Vision: Alcohol impairs the eye muscles’ ability to focus properly, leading to blurred vision. This effect is particularly noticeable when trying to read small text or view distant objects.
  2. Reduced Peripheral Vision: Alcohol consumption narrows the field of vision, making it challenging to perceive objects on the sides without turning the head. This diminished peripheral vision can increase the risk of accidents or misjudgments.
  3. Decreased Depth Perception: Alcohol affects depth perception, making it difficult to accurately perceive distances between objects. This can impact tasks such as driving or playing sports that require accurate judgment of distance and spatial awareness.
  4. Slower Pupil Response: Alcohol affects the pupils’ ability to constrict and dilate in response to changes in light levels. As a result, the eyes may have slower reactions to sudden shifts in lighting conditions, leading to temporary vision disturbances.


  1. Impaired Decision-making: Drunk eyes can contribute to poor decision-making, especially in social situations. The altered perception caused by alcohol can make individuals perceive others as more attractive or appealing than they actually are, leading to potentially regrettable actions.
  2. Increased Risky Behavior: The distorted vision experienced with them can diminish the perception of potential hazards, leading to an increased likelihood of engaging in risky activities such as drunk driving or unsafe sexual behavior.
  3. Accidents and Injuries: Impaired vision due to this condition can lead to accidents and injuries, both for the person under the influence and those around them. Reduced visual acuity, peripheral vision, and depth perception can hinder one’s ability to navigate safely and react appropriately to potential dangers.


Drunk eyes, resulting from alcohol’s impact on the visual system, can cause various symptoms such as blurred vision, reduced peripheral vision, decreased depth perception, and slower pupil response. These visual changes have significant implications for decision-making, risk perception, and the potential for accidents or injuries. Understanding the effects of alcohol on vision can help individuals make informed choices, promote responsible alcohol consumption, and foster a safer environment for all.
