Style F11 looks like a pair of regular sunglasses with mirror lenses. These are polarized mirror lenses and they are scratch resistant. They will only go over smaller to medium size prescription glasses and fit best over rectangular shaped glasses.
Please note that the color mirror is only on the front of the sunglasses.
The side window lenses just have the gray non mirrored lenses.
Also, the color of the mirror lenses are hard to describe. The lenses all appear to have
a mixture of colors depending on how you hold them up to the light.
