My boyfriend got hit on the inside of his eye from some debris.now he has a blood spot in his eye should we go to er?

Yes: If the debris hit the eye with such force that there are now blood spots, it is best to get it examined.

No 'spare' eyes, ER!: What you describe could be serious or could be harmless, just not enough info to say for sure--but we only get one set of eyes (for now), so take the best care of them you can and get them evaluated in the er asap.

Yes: That spot could be a small hemorrhage from a fragment and could lead to more issues in that eye, including infection. Would recommend going to an er where they can do a thorough exam.
