I lived in south Texas, where the humidity is only rivaled by the high, searing sun. I bought these glasses because they are cute, and I wore them for the first time is now mid June .on the tennis court, and the compliments I received Were nice, but more importantly, the glasses shielded my blue eyes from thre suns relentless glare. To me this is remarkable, because I Have sunglasses that by Oakley that I usually wear. Although  this Shaderz sunglasses are not polarized, they're just as effective at 5pm in the high sun in San Antonio. Will update if there is any bubbling or peeling.
