I ordered the Oakley Flak (RX) when I tried them on they appeared bigger than the normal lenses. The sales rep. measured the lenses and the RX lenses were 1mm bigger in length than the normal sunglasses lenses, which makes a difference, I have a small face and they look too big for my head. The rep. did not tell me the lenses stretch when the prescription is added to the lenses...Anyone know is this right....
