When I saw these super nifty sunglasses, I laughed at the ingenuity in the design!  How stylish and unique these sunglasses are when Round lenses are super large where a slight visor is incorporated into the design to also be useful.  The lenses come in brown w/gold frames.  The lenses measure 2 -3/8" in diameter.  The "visor" protrudes out at it's widest width  5/16".  More would be too much!  They are light weight and have a spring hinge and are sturdy.  They are ultraviolet sun ray proficient as UVa & UVb 400 strength are there.  Might I suggest that if any of your male friends, family members like large lenses the UNISEX style works, especially for golfers!  I strongly suggest buying a HARD case cover for them too!  NOTE: The ONLY hard case covers that will fit these large sunglasses are sku # 10163spec.  These are in tan or pink which are extra large in size.  The gold w/go great with either case. If you do NOT want the crystals on the hard case, check it off on the drop down menu when ordering the case.
