The lenses are high-quality poly-carbonate (aka plastic) -- I don't get the eye strain like that I would when wearing cheap sunglasses from Wal-Mart or Target. The pair I received was &#34;Made in Italy&#34; but yours might be &#34;Made in China.&#34; Your vision will take on a really strong sepia tone so look elsewhere if you prefer your vision to be as true to life as possible.<br /><br />Minus 1 star for the shiny frame that looks and feels really cheap in spite of the $165 retail price tag. They are comfortable enough, and the rubber on the nose bridge helps stabilizing the sunglasses when you get sweaty.
