This is a great product. Through the years I’ve own two pairs and I just ordered a third pair now all of the Cabela model. The blue mirror coating on the polycarbonate lenses doesn’t seem to last past 3 to 4 years. It starts to chip off otherwise the glasses would continue to be functional. I did order the high index lenses this time in hopes that the coating on the lenses will last longer. Other than that, I love the prescription, progressive lenses, and the frames.
