I ordered this item expecting the glasses to be very cheaply made and flimsy. I was very pleasantly surprised upon their arrival. They are put together well and seem quite durable. The quality in manufacturing is high. The hinges are secure and strong, the colors are vibrant and clear-coated to prevent chipping or peeling off. The glitter on the "rim" is a great touch, but after prolonged use will probably wear off. The glasses fit well, are not too big or too small, and I suppose you could say I have an average-sized adult human head.

I cannot comment on the sun protection, as I have yet to wear them outside. They will be used to add fun to my drunken vacation in Mexico, so that is not a huge factor for me.

The only issue I ran into is the website description says "6-pack". I only received one pair of glasses. I ordered from an Amazon-fulfilled vendor and after contacting them, Amazon is sending me the correct amount of items. You may want to double-check with the vendor you choose to make sure you will indeed be getting 6 pairs of glasses.
