they're kinda a larger size, more men's size or wide headed maybe?  They're okay for driving (however the warning says not to drive with them on) but just wearing them outside you can't see well because the tint is so dark.  I wore them to the park and and zoo with my kids and had a hard time seeing much detail of anything with them on.  They also scratch SUPER EASILY.  I had a different pair of sun glasses (cheaper pair) for 3 years before they were too scratched.  These scratch without even trying!
