Bought these as they are for big heads. Yes the lenses are big but the frames are quite small and narrow for my big head. The arms are short and don't set right on my ears. It would hugely help if they had spring hinges. They are surprisingly narrow. The tips of the arms measure about 3 1/2" across,,, really? No way these are big and tall sized. Would not recommend if you have a large head. They were narrow on my wife that has a normal sized head.
