Best safety glasses/sunglasses I ever bought.
These things are great. At full darkness they aren't as dark as my other sunglasses, but I assume if they were to they wouldn't work like they should. Even so they are dark enough. I work Emergency Medical Services. I'm in and out of buildings, vehicles, the ambulance, you name it. I have had no issues with the tint changing. The changes are so subtle you will not notice it. In a minute they are as dark as they will get. They do take a little longer to get back to the full clear lense, but not very noticeable. Maybe a minute and a half. The lenses have a perfect covering for your eyes for use as safety glasses. The frames are sturdy and comfortable. I wear these sometimes for 8 hours in the day. You won't even realize you are wearing them. They include a strap that clips on the back of the frame to help so the gasses won't fall off. You won't need it. If you are in and out as I am, you won't regret buying these.
