These are by far the best glasses I have ever owned and I have owned several pairs from other top tier manufacturers. They are light weight, they don't slip around, they are extremely comfortable and most of all they look good.
These perscription style glasses are extremely comfortable. With adjustable ear stems its makes for a personalized fit. I also love there nose pieces being made from there patented material that keeps the glasses from slipping if you sweat. These have been worth every penny!
