Optometrist or Eye Specialist?

Yesterday I walked around the corner with my baby son - three months old. The sun was bright and kept hitting us from behind houses etc I guess it was going down and 3pm ish and I tried to shade his eyes the best I could. he was not wearing sungles as it is February! I was carrying him so there was no buggy visor. He squinted when it changed direction and hit us in the eyes. Would this have caused him any harm?
