Alba Optics Stratos Purchased from Tokyo Wheels 2 years ago. These are very convenient lenses, with both photochromic and polarized features. Please see the photos to observe the lens's transition between bright and dark conditions. There are a few minor scratches, though they're not very noticeable. Please refrain from purchasing if you are overly concerned about this. These are quite expensive recently, so if you'd like to try them out, please do! I'm also selling other sunglasses, so please take a look if you're interested.
