Common Causes of Red Eyes

When the whites of the eyes look bloodshot, it’s because tiny blood vessels fill up beneath the eyeball’s transparent outer layer. Common causes of red eye included everything from allergies to eye infections.

The swollen blood vessels can either appear as red lines across the sclera, or they turn the whites of the eye pink or red underneath the conjunctiva. Regardless, bloodshot eyes may be a reason to see an Ophthalmologist because caring for one’s eyes is essential.

The Environment and Our Eyes

Pollution and air-born allergens cause irritation, burning, itching, and dry or watery eyes. So do dry or arid climates and the artificial conditions found in an office or an airplane cabin. Lifestyle habits such as drinking and smoking cigarettes are common causes of red eye problems symptoms, as well.

Additionally, red eyes are indicators that something is wrong. Though it’s not unusual to get red, irritated, or bloodshot eyes, some severe issues to be aware of bring it on too.

When to See an Ophthalmologist

There’s not always a way to be sure about what’s causing red eyes. That’s why instead of using over the counter eye drops that “get the red out,” it’s a better idea to visit the eye doctor.

The reason to avoid medicated eye drops is the vasoconstrictors. They shrink the eye’s blood vessels on the sclera, making the whites white; however, they also create dependency because of a significant decrease in volume and tear flow with consistent use.

Another thing to remember is that if there are blurred vision and discomfort associated with red eyes, it’s essential to see an ophthalmologist as soon as possible. These additional symptoms could be a sign of more severe issues such as eye trauma, glaucoma, or a corneal ulcer.
