Just had some bloke come in and as for some glasses that have the lenses tinted only half was across the lenses. So clear on the left, black on the right. So that the black is covering the lights for on coming traffic. “umm wont that be a bit dangerous, like wareing blinkers. Stopping you from seeing anything to your right” “no cos you can turn your head, why dose no one seem to do them?” well my photo shop mock up….. This berk will probably be on dragons den soon
