During the physical examination in our school, it will be indicated on the form that students with vision problems cannot be cooks. If your friend works in a restaurant and doesn't become a chef, there is no problem at all.

Actually, I don't think it's necessary to care what others think. The most important thing is to have confidence in yourself. Indeed, there are many people in this society. You don't have to care what everyone thinks. Good luck to your friend!
