What Happens to Your Eyes When You’re Drunk?

We all know that excessive alcohol consumption can impair our judgment, coordination, and reaction time. However, have you ever wondered what happens to your eyes when you’re drunk? Alcohol affects various parts of our body, including the eyes, leading to noticeable changes in our vision. Here’s what you need to know about the impact of alcohol on your eyes.

1. Bloodshot Eyes: Alcohol causes blood vessels to expand, resulting in bloodshot eyes. This occurs due to the dilation of the blood vessels in the sclera, the white part of the eye.

2. Dryness: Alcohol acts as a diuretic, causing dehydration throughout the body. Consequently, your eyes may feel dry and irritated when you’re intoxicated.

3. Blurred Vision: Alcohol affects the central nervous system, including the brain, which plays a crucial role in vision. As a result, your vision may become blurry when you’ve had one too many drinks.

4. Reduced Peripheral Vision: Alcohol impairs the ability of your eyes to focus and track objects. This can lead to reduced peripheral vision, making it more challenging to perceive objects from the corners of your eyes.

5. Slowed Pupillary Reflex: The pupil of your eye responds to changes in light, adjusting its size accordingly. When you’re drunk, this reflex tends to be slower, impacting your ability to adjust to varying light conditions.

6. Depth Perception: Alcohol affects your depth perception, making it harder to judge distances accurately. This impairment can be dangerous, especially when driving or engaging in activities that require precise spatial awareness.

7. Increased Sensitivity to Light: Many individuals experience heightened sensitivity to light when intoxicated. This can result in discomfort and even headaches when exposed to bright lights.

8. Altered Color Perception: Alcohol can affect how you perceive colors, making them appear more vibrant or dull. This change in color perception can be temporary and subside as the alcohol is metabolized by the body.

9. Nystagmus: Nystagmus refers to the involuntary movement of the eyes. Alcohol consumption can exacerbate this condition, leading to uncontrolled eye movements and difficulty focusing.

10. Delayed Reaction Time: Alcohol slows down the transmission of signals between the eyes and the brain, causing a delay in reaction time. This can affect your ability to respond quickly to visual cues.

11. Increased Risk of Eye Injuries: Impaired coordination and judgment due to alcohol consumption can increase the risk of eye injuries. Accidents like falls or getting hit in the eye are more likely when you’re intoxicated.
