I am an ophthalmologist on this site. Are both eyes involved?
Do you have any burning in your eyes as well?
There can be a few possibilities. It can be because of episcleritis or a sub-conjunctival hemorrhage. Sub-conjunctival hemorrhage is a ruptured blood vessel and does not require any treatment. Episcleritis will require steroid drops. You need to see an ophthalmologist to confirm the diagnosis. Even dry eyes or allergy can cause red eyes but usually they are not so localized.
