Bests & Worsts Reviews from Amazon

I am a pharmacist and have to wear a mask all day for COVID. My glasses are constantly fogging up. I’m in desperate need for an anti fog. I bought Z Clear. This stuff is awful. It doesn’t work at all and it’s a waste of money. I would give it zero stars if I could. I am really not one to write negative reviews. Since many medical professionals are looking for something, I would not recommend this stuff! I followed the application instructions to the T and this stuff is useless. :(
