Bloodshot eyes means that the small blood vessels on the surface of the eye have become enlarged and congested with blood.

Eye redness can happen when the blood vessels on the surface of your eye expand or dilate.

This can happen when a foreign object or substance has gotten into your eye or when infection has formed.

Eye redness is usually temporary and clears up quickly.

Red eyes alone are not usually a reason for concern.

However, if there is also eye pain, watering, dryness, or impaired vision, this can indicate a serious medical problem.

Red eyes are usually nothing to worry about, as long as they don't happen often and don't last long.

You might find brief relief in over-the-counter artificial tears that wash and moisten your eyes.

Decongestants and antihistamines can help with itchiness and redness because of allergies.

High blood pressure and red eyes often occur simultaneously.

The eyes are full of blood vessels, and they typically stiffen and join each other in instances of high blood pressure.

Call 911 or your local emergency number for red eye if: Your vision changes suddenly.

It is accompanied by severe headache, eye pain, fever or unusual sensitivity to light.

You also experience nausea or vomiting.

Remedies for red eye or bloodshot eyes are wide-ranging.

Many times, rest, cool compresses over closed eyes, lightly massaging the eyelids, gently washing the eyelids, and/or over-the-counter eye drops, can relieve the symptoms.

Other times, an eye doctor may recommend and prescribe antibiotics, special eye drops, or ointments.
