I'll make it simple. I have a big head and a broken-several-times nose, so I need a big pair of glasses that fit just right. I had a pair of Oakley Frogskins (purchased in 1998) that I wore for about 10 years, they were amazing. After many years of abuse (lifeguard = tons of exposure to the sun = frame material degrades and weakens until it cracks) I finally caved in and bought some new glasses. The Hijinx fit so perfect, they're super light, the polarization is top-notch. You only get one set of eyes, protect them right. These glasses are worth every single penny.
