These glasses were purchased specifically to help with an eye condition known as " dry eye". With this condition quite the opposite occurs with continual watering eyes particularly in cold windy condition . The glasses are first class in creating an enclosed atmosphere around the eyes which is a massive help. Also the arms can be easily formed to hold the glasses close to the eye socket.
So, all in all for a sun glass that is primarily sold as a mountain glass it is excellent for my specific requirements and would not hesitate in recommending them for anyone with a similar condition. They look pretty good too!
