I'm an HVAC engineer and I bought these glasses to use in the field because I'm always popping up ceiling tiles and pieces of fiberglass sometimes get into my eyes. These glasses are very good and clear to use in the field, no problems of fogging up.

Would recommend.

I have been using these glasses when using my trimmer, and they are very comfortable. All the adjustments allow for a great fit and the soft material that rests on the nose and touches the brow provides comfortable support without slipping. In Hawaii it can get a bit humid which gave me a chance to test the anti-fog feature, which has passed with flying colors. I would only recommend that one clean them with soap and water and then let them dry, and not use a cloth or paper of any kind to rub the lenses. Then you will end up with a scratch free surface that should last a long time.

I was looking for a nice pair of wrap arounds that kept me from fogging them up. These did the trick!
