My 6 yr old son was running and fell and hit his eye on a picnic table. He has a couple of cuts under his eye. The corner of his eye is also blood red and his eye lid and right under the eye are bruised. He told us that when he went outside for recess the first day after it happened it was blurry in that eye, but says it is fine now. Should I be concerned about his vision or anything else and take him to a doctor?
