A subconjunctival hemorrhage occurs when a tiny blood vessel breaks just underneath the clear surface of your eye (conjunctiva). The conjunctiva can't absorb blood very quickly, so the blood gets trapped. You may not even realize you have a subconjunctival hemorrhage until you look in the mirror and notice the white part of your eye is bright red. A subconjunctival hemorrhage often occurs without any obvious harm to your eye. Even a strong sneeze or cough can cause a blood vessel to break in the eye. The most obvious sign of a subconjunctival hemorrhage is a bright red patch on the white (sclera) of your eye. Despite its bloody appearance, a subconjunctival hemorrhage should cause no change in your vision, no discharge from your eye and no pain. Your only discomfort may be a scratchy feeling on the surface of your eye. Credit: @drwyattnk @optometry.case
Can't help but think this image is a bit doctored for drama. Comparing other pics of this, that color looks too smooth and florescent with no swellings. At least I hope it's not
