5 Overglasses Posted by William C Sinclair on 28th Jan 2019 I drive 20 miles going against a long line of dipped beam cars on extensive straights to work in the morning. The glare and r from the oncoming lights is very tiring especial lly when it is raining. The glasses have made the world of difference. I can say that the glare is cut by about half. What a great purchase.
