It looks like the injury is on the outside as well as on the front part of the eye ball. Is the eye staying the same, or shrinking/swelling or discolouring? If its staying the same I advise picking up human grade eye ointment with an ab (polysporin) but without steroids in it to put on the eye twice a day. See if that help. IF you see any changes that I mentioned, then get your beautiful boy to the vet.
