1st... I'm a mailman. I am out in the sun constantly. 2nd... I have multiple pairs of sunglasses i.e. Oakley, RayBan, Persol, S'getti, Arnette and Tom Ford. These Apollos Vision sunglasses are amazingly light in fit and comfort. They are polarized. I Love them and would buy again. Makes me wonder why I bought the above mentioned brands.
