Eye Conditions: Red Eyes
by Ronald Hoyle, O.D.
Red eyes commonly plague patients and may indicate more serious underlying problems. Redness generally indicates a vasodilation of the blood vessels within the eye accompanied by swelling and symptoms ranging from burning and itching to eye pain.
All red eyes should be examined by an eye care professional as many causes include bacterial or viral infections as well as allergies or poor fitting contact lenses. Never touch the affected eye as transmission from eye to eye may be possible. Contact lens wearers should remove their lenses and consult their eye doctor immediately.
Most red eyes can be readily treated if the proper diagnosis is made. Red eyes may also indicate a reaction to certain medications or preservatives and therefore also require examination by an eye care professional.©
