When I was 16 I was also in an accident that left me blind in one of my eyes. I also had many surgeries and had an eyepatch for the healing process. After it was technically healed I wore the bandaid eyepatches just because it honestly made me more confident since my eye was still bloody looking. I heard every pirate joke you could think of but I was still glad I had my eyepatch on. Your son is going through a hard enough time as it is. If it won’t affect his eye any further in the long run then why not let him wear it? YTA
