"Quick and simple order process, glasses arrived quickly in Canada. Hemiplegic migraine sufferer, forced to drive through sunlight flicker through trees to come and go from home. Glasses help immensely, wrap around style cuts periphreal glare while driving with sun on driver's side. While the glasses can't stop the sunlight flicker and flash, they do reduce the amount of light in those flashes, and minimize the contrast with those flashes, which helps a great deal. I also found the glasses improve my vision when driving in slightly misty or slightly foggy daytime conditions. Happy with purchase."
