Not sure how old your child is, but he may have autism. My daughter has developmental delays and has many autistic traits - being scared of visual as well as auditory stimulation is a common theme. It can't hurt to check it out - if nothing is wrong that is great. If they find something is wrong at least you can implement strategies that will help.

try to relax him and try to show him things with smiling and try to convince him that he is protected and nothing will happen to him

thank u guys! that was pretty helpful
