considering it doesn't hurt, this may be your problem

Subconjunctival Hemorrhages (Eye Bleeding)

This eye injury usually looks worse than it really is. A subconjunctival hemorrhage involves leakage of blood from one or more breaks in a blood vessel that lies between the white of the eye (sclera) and its clear covering (conjunctiva).

Subconjunctival hemorrhages are quite common and can occur from even minor injury to the eye. They may be limited to a small sector of the eye, or they can extend over the entire eye, making the white sclera appear bright red.

A subconjunctival hemorrhage is painless and does not cause temporary or permanent vision loss. No treatment is required. Over the course of several weeks, the blood will clear and the eye will return to a normal appearance.

However, you probably should go to the doctor to check if you actually did scratch your cornea, in which case the injury would be more serious

ok well yeah now u should get it checked... you might have scratched it harder.... don't be too worried, but just get it checked out :) to be safe

Yeah no you should probably get it checked out now. It could turn into something serious if you don't do something about it.
