that astronaut is blind now. The black tint on the visor is to protect from the incredibly blinding sun. on earth you can allow the sun to be in your peripherals for a few moments or even stare at it directly for a split milisecond if you're really stupid, but that's because you have the atmosphere and plenty of other things to protect you. in space any part of your retina that receives any kind of light from the sun if you have that visor flipped up is just dead. immediately. no exceptions.
