Imagine you wake up one morning, and your eyes look like they’ve turned red or pink. That’s what we call bloodshot eyes! It happens when the tiny blood vessels on the surface of your eyes get bigger and more visible, giving your eyes a reddish appearance.
Bloodshot eyes, also known as red eyes or conjunctival injection, occur when the blood vessels on the surface of the eye (the conjunctiva) become dilated or swollen. This dilation is often a response to various factors, which can be internal or external. Here are some potential reasons:
Commonly known as pink eye, it is an inflammation of the conjunctiva caused by viruses, bacteria, allergies, or irritants like smoke and chemicals.
When your eyes do not produce enough tears or the tears evaporate too quickly, the eyes can become dry and irritated, leading to redness.
Exposure to seasonal or environmental irritants like pollen, pet dander, mold, or air pollution can cause eye irritation and redness, especially in individuals with allergies.
Prolonged use of digital devices, reading, or other activities that require intense focus can cause eye strain and redness.
Not getting enough rest can make the blood vessels in your eyes more visible and lead to redness.
Wearing contact lenses for extended periods or not cleaning them properly can lead to eye irritation and redness.
If something gets into your eye or if you injure your eye, it can cause redness and irritation.
Smoke, dust, or other irritants can lead to red eyes.
This occurs when a blood vessel in the eye bursts, leading to a bright red patch on the white part of the eye. It’s usually harmless and resolves on its own.
In some cases, increased pressure within the eye due to glaucoma can cause redness.
Eye infections, like styes, can cause localized redness.
This is an inflammation of the eyelids, often caused by bacteria or skin conditions. It can lead to red, swollen, and itchy eyes.
Drinking alcohol can cause dehydration, which may result in dry eyes and bloodshot appearance.
Accidental contact with chemicals or household cleaning products can lead to eye irritation and redness.
Uveitis is inflammation of the uvea, the middle layer of the eye. It can cause redness, pain, and blurred vision.

If you are experiencing persistent or severe redness in your eyes, along with other symptoms such as pain, discharge, changes in vision, or sensitivity to light, it’s crucial to seek medical attention promptly. An eye doctor can properly examine your eyes and provide an accurate diagnosis and appropriate treatment.
