Id pay 10 bucks for these. The frame is sturdy, the lenses are very very dark, these are perfect for someone like me that doesnt typically wear sunglasses unless its blindingly sunny outside, i literally put them on and stared straight into the sun and other than the fact that its bad for you, i didn't mind it. Being an avid motorcycle rider these are great for killing that a-hole glare off of random chrome parts of cars that seems to reflect the full energy of the sun and always leave a blue dot in my peripheral.
