Can one get red eyes from drinking alcohol?

While alcohol itself doesn't directly cause red eyes, it can contribute to them in a few ways:

1. Dehydration: Alcohol is a diuretic, meaning it makes you urinate more frequently. This can lead to dehydration, which can cause blood vessels in the eyes to dilate, leading to redness.

2. Blood Vessel Dilation: Alcohol can cause blood vessels to dilate throughout the body, including those in the eyes. This dilation can make the whites of your eyes appear red.

3. Sleep Deprivation: Alcohol can disrupt sleep patterns, leading to tiredness and fatigue. Lack of sleep can also contribute to blood vessel dilation and red eyes.

4. Irritants: Alcohol can irritate the eyes, especially if it gets into them. This irritation can cause redness and inflammation.

5. Eye Strain: Staring at screens for extended periods, which is common after drinking, can strain the eyes and lead to redness.

Important Note: If you experience persistent red eyes or other eye problems, it's crucial to consult an ophthalmologist to rule out any underlying medical conditions.
