What Causes Bloodshot Eyes?

We’ve all experienced it at some point—you glance in the mirror and notice your eyes look red or irritated. Bloodshot eyes can be alarming, but most of the time they are caused by something minor. However, in some cases, they can indicate an underlying condition that needs professional care. Let’s break down what causes bloodshot eyes and when you should book an eye exam at OptoDoc.

Common Causes of Bloodshot Eyes

Dry Eyes: When your eyes don’t produce enough moisture, irritation can make them appear red and inflamed.
Allergies: Seasonal or environmental allergies often trigger red, itchy, watery eyes.
Eye Strain: Spending long hours on digital screens can cause your eyes to become tired and bloodshot.
Lack of Sleep: Fatigue makes blood vessels in your eyes more visible.
Contact Lens Overwear: Wearing lenses too long or not cleaning them properly can cause irritation and redness.
Environmental Factors: Smoke, wind, chlorine from swimming pools, or dry air can all irritate your eyes.
Infections: Conditions like conjunctivitis (pink eye) cause bloodshot eyes along with other symptoms like discharge or pain.

When Should You Be Concerned?

Occasional redness usually isn’t serious, but if your bloodshot eyes are persistent, painful, or accompanied by vision changes, it could be a sign of something more serious like an infection, glaucoma, or a corneal issue. These require immediate attention from an optometrist.
