Is the vision affected?
It is most likely to be a sub-conjunctival hemorrhage. Although its appearance may be alarming, a subconjunctival hemorrhage is generally a painless and harmless condition. The causes of a sub-conjunctival hemorrhage could be -
Minor eye trauma
increased venous pressure
Blood dyscrasia (rare)
A subconjunctival hemorrhage is typically a self-limiting condition that requires no treatment in the absence of infection or significant trauma. At the most you can use a lubricating eye drop like Refresh Tears 3 times a day. Thanks.
