Cleans the lenses well. But the only thing I have to say is that a few towels were dry.I like the towelettes...I DONT LIKE THAT THE BOX CAME SMASHED ....... THANKS FOR NOTHING AMAZON YOUR SHIPPING HAS BEEN GETTING WORSE AND YOU RAISED YOUR PRICES ON PRIME HOWS THAT ADD UPThis product is effective but I find inconsistent in the moisture content some seem to be good where I have found others a little dry and evaporate to quickly and some just dry as a bone.These wipes are inexpensive and do a good job at cleaning your glasses. No streaks or smudges. But when it comes to anti-fog, which is what I was hopping to get help with, not so much. They do help a little. They're definitely better than not using anything at all. But they are not really anti-fog. And, the little effect they do have, lasts about 15-20 minutes.Use for work safety glassesI gave only 4 stars because I didn't experience any help with fogging of my glasses. They work quite well for cleaning as they are not too thick and I think it is a good value for the money considering the large amount provided.I clean my glasses several times a day and use the still moist towelette on phone or laptop.I originally bought these for the "anti-fog" purpose as advertised, However, I really like the way they clean my glasses, and so have bought a second box.
