To replace the lenses in your full frame style glasses, start by turning the frame around. Pull up on the top of the frame, and pull down on the bottom of the frame while pushing the lens through. You will hear some popping sounds. This is normal. It’s just the lens unseating from the groove of the frame. To install your new Revant lenses, line the upper nose of
the lens into the frame, seating it into the groove. Work your thumbs around the frame, popping the lens into place. Last, take your thumbs and run them around the perimeter of the lenses to ensure they’re locked in.
