Wish they were slightly smaller to fit a small adult. I had to use sleeves to make the not fall off. But work perfectly and the purple mirror on the lenses is very cool.I liked the look and feel...but the mirroring wore off after only a few weeks...I am pretty careful with glasses...so it is really a product defect.I got them for my mother in law and she absolutely loves them. They arrived on time and as advertised.All good.I would love to give these a 5 stat but in less than two months they have formed lines in the lens. The arms are also no straight like they should. I wish I saved my money.2nd pairLenses are nice but they sit too far from the face so light and air gets in from the side. Annoying for driving and doesn't block air so no sports like biking or skiing.At first these were great but now after 6 months the lens coating is peeling off and there is no way to contact the seller. So I guess it’s buyer beware.pratici,comodi,molto leggeri.....li comprerei di nuovo!!Beware, they are selling you polarized lens and this is not the case.
