The glasses correspond to the description. All seems good, to see in time. Accessories complete. No explanatory note concerning the function of the different lens colors. But we find little information on the web! The box is very convenient for storage and safe transport of glasses and accessories. First use, quite happy. The lens surface is sufficient, optimal eye protection. They are lightweight comfortable to wear, it just set small support legs for the nose. Changing lenses very easy. Another plus, the scope for corrective lenses. Remains to be seen with your optician to put in place corrective glasses!
