I thought it is about time I let you know how pleased I am with my "Extreme Glare" glasses. They are light and a pleasure to wear. They are great to use when driving as well as to fly my radio controlled planes. As you know the danger of flying into the sun, losing sight of a plane and then trying to find it in the big sky is unnerving. It is expensive not to get it back in sight in time for the ground to be avouded. With your glasses I do not lose visual contact.
