At first I thought it was much worse since the pic at first looks like there is more than a broken visor. Still healing vibes to him. Fingers heal fast fortunately. 2-3 weeks and you're fine. Unless something more happened it shouldn't really traumatize him.
Only helmet I know of with a flexy visor is the urge. Would be nice if all helmet brands adopted that material for visors, if for the only reason being that it won't shatter when you face plant. Not cutting your face would be an added bonus. Destroying your visor is annoying, cause you almost certainly don't have a spare and will have to ride around looking like a doofus until a replacement arrives
