Subconjunctival hemorrhage is a common symptom of eyes. It happens to almost everybody for anytime. For most cases, it may recover soon in few days thus there is no special treatment for that. However, I do understand it is terrible as I suffer it once. Anyway, I have got an effective treatment which I can share. For the first one or two days, press your eyes with ice cube. If it is too chilly you can package the cubes with towel. This step is to stop the bleeding. Then, for the next few days, press your eyes with warm towel. This is to accelerate the circulation around your eyes so that the cumulated blood will move and your eye will not be red anymore. When I do this, my eyes recover after three days and I feel perfect about my eyesight. You can have a try.
