I've been using a more expensive pair of indoor/outdoor safety glasses and decided to try these. Wow, I wish I had bought these first. These glasses knock down the glare when outside but do not darken things to the point that they become uncomfortable indoors. Since 80% of my work is indoors, I like the convenience of a pair of glasses that I can use in or out. It's just far simpler for me than constantly changing the glasses I'm wearing. Highly recommend these glasses.
