Photochromic Safety Glasses Darken and Lighten Automatically



These photochromic safety glasses actually provide what they say they do.  This is a black graphite patterned frame with lens that are treated with a chemical that allows them to darken and lighten automatically.  Partly cloudy day?  Use these safety glasses.  Working with metal that can have a wicked reflection?  Use these safety glasses!  Comes with a hard sided case so they can always be handy.
