I had these in an Rx with the radar range size. awesome lens! i biked across the country in the summer of '08 with these. it handled the punishing sun well, and looks wise it is probably the best looking lens from the outside. i find the tint tends to give a bluish cast to everything, so not as ideal in that respect, compared to, for example, a vr28 black iridium with a rose tint. also not a good lens for overcast days. the strength of this lens is its ability to neutralize bright sun.

Very nice. Fits almost every frame color and can be worn in every condition. I expected it to be very dark to look through but that isn't the case. Even in low light conditions it's very easy to see through. Colour, contrast and clarity are all excellent. An inescapable side effect of Rx lenses is that thickness of the lens (and therefore darkness of the color) depends on the strenght of the prescription.
