Burst Blood Vessel: Will my eye heal itself?

I've developed a bright red eye, for no obvious reason. The doctor says it's a burst blood vessel that will heal itself. It looks terrible, but feels fine. Should I be worrying?

Dr Fred Kavalier answers your health question:

You have a sub-conjunctival haemorrhage, caused by a tiny burst blood vessel in the white of the eye. It can appear for no reason, but sometimes it is the result of a minor eye injury, or even just rubbing your eye. As long as your vision is fine, and it is clearing up, don't worry. It will be gone in about 10 days.
