I recently got square wires with VR28 glasses. The guys here were right- the VR28 is amazing versatile! It enhances contrast and is wearable from sunny to rainy light conditions. I even wore them in an indoor range without target ID problems.
My optician recommended reducing the prescribed correction a little bit because you wear the Rx Oakleys a lot closer to your eye than normal glasses. Still, my experience has been weird: with the Oakleys, flat surfaces on the ground seem a lot "rounder" than they are. Only when I view directly through a very small area in the center of the glasses, I don't get that effect. How/if optically untrue the glass is, I can't say. I have considered writing Oakley USA, but I am not sure if it is just me who is bothered by this. Anybody else got this weird problem?
With -3.5 nearsightness, maybe I am on the edge of what is doable in a curved lense without distortions. I may go back to contact lenses & nonprescription Oakleys, where I never experienced this.
