Eye Redness and How to Treat It

Subconjunctival hemorrhage

A less common type of red eye is a single, dramatic blood-colored patch on the eye. This blotch is typically a bruise similar to what you may have on the skin. It may arise after a minor bump or even coughing or sneezing. High blood pressure and use of blood thinners increase the chance of a hemorrhage.This generally clears up in two weeks without any treatment. You should see a doctor if you’re having any pain or persistent discomfort.
