First off I'm used to Metal Frame/Glass Lens Ray Bans so these are much lighter to wear -Much better for active use.  They are a #3 on Oakley's light scale (0 = no tint to 4 = snow+sun) and are just about perfect on a fully sunny California day as far as I'm concerned.  And as others have mentioned, the glasses have actual Oakley OEM polarized lenses.

My only disappointment is that the coverage is slighty less than I expected, i.e. the light comes in from the top of the frame more than I'm used to.  Regardless, I still give them a 4/5 stars given the weight, fit, and that they are genuine Polarized Oakley's for around $100.
