BLOODSHOT EYES: broken blood vessels in the eye covering. Not dangerous. Causes = coughing, sneezing, heavy lifting, a rough night, eye rubbing, blood clotting problem. Aspirin makes it look worse. Gentle warm compress 3X a day for 5 minutes can make redness fade faster. Lasts 1-3 weeks. If it happens without an obvious cause, have your blood clotting tested.

Hope this helps

Bob.

P.s. L.O.L @ "a rough night"
