Review on American Silicone Breathing Comfortable Protection Occupational Health & Safety Products by Will Powers

THESE STOP GLASSES ARE FOG! However, I will say that you have to play with the fit a bit, but if you get it right they work fine. It helps with airflow and breathing, which is why I use it when I need to wear a mask for long periods of time. (I have asthma so it becomes difficult to breathe through the mask after about 30 minutes). You might actually notice the silicone when you first apply it, but after a while you forget it's even there. Mask up and down to eat or drink, I still have to adjust. So that's a minus in my book.
