what causes blood vessel to break in eye
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. You don't need to treat it. Your symptoms may worry you. But a subconjunctival hemorrhage is usually a harmless condition that disappears within two weeks or so.
