Solid Deal.

I've owned several Smith sunglasses. They're nothing really special, normally some type of plastic frame with poly- carbonate lenses. I use the interchangeable lenses for cycling. Dark brown for bright conditions and amber for riding through the forest during the day --- or on the way out after sunset.

These Bauhaus shades are photochromic. Meaning they adjust darker or lighter, according to the amount of light. For $30. I cannot find them anywhere for less than $60. Thirty dollars. SOLD!
