RELAX! I’m sure your eye care professional has told you this and if this is your first Subconjuctival Hemorrhage they are telling the truth. I know your eye looks incredibly red, but it’s actually just a drop or 2 of blood in-between 2 layers of tissue, so it spreads out, kind of as if you put a clear film on top of a drop of water and watch how the water spreads. How does this happen? Coughing, sneezing and straining are the most common way to pop a blood vessel. It can also happen from trauma or eye rubbing. If it happens repeatedly it may be due to medication or bleeding disorders and you should consult your Doctor. There is no treatment; you just have to wait a few weeks for it to clear up on its own.
