The Body Doctor Anti-Fog Dry Cloth, Demister Lens Wipe for Glasses, Stay Mist Free for 48 Hours, Reusable up to 1000 Times, Single Pack

I have a big problem with my glasses and goggles misting up. These cloths are only ones that work to stop fogging. I've tried sprays and other methods but these cloths do the job brilliantly. I use them before swimming to keep my goggles clear when indoor and outdoor swimming.

Edited, please read in full.OK, I am testing kids in schools for Covid and I am the only person with glasses who can see.The cloth works, with a caveat.As I have very sensitive eyes, being very, very shortsighted, I can see the difference in my lenses. To start it was a negative, until I changed my attitude.There was no mist, there is a clear film of water that stays on the lenses and eventually evaporates.During the time it is visible, I took this as failure.I WAS WRONG.Once you realise that the mist basically flattens out to become see through, but is still there, until it evaporated.So, be patient. It works, albeit in an odd way.The Second picture is today, no steam or must, I can see where others don't.First day. Doesn't work. Useless.(I THOUGHT!)I was so excited last night, got to work and two minutes of mask wear and the cloth is DEFEATED. (IT WASN'T)######I cleaned my glasses as normal, fogged them with my steamy breath and used the cloth as directed.Presuming this would be a waste of time, I was wrong. It only flipping well works.Now them the real test will be back at work tomorrow in full PPE. I'm going to use it on mine and my collegues glasses and see what happens. Stay tuned.

Like others, I was sceptical. The first time I tried this cloth my glasses still fogged up. Then I followed the instructions TO THE LETTER. You have to clean the glasses perfectly - I use Tesco disposable spectacle wipes. You must then let them dry completely. Then you must breathe on just ONE SIDE of each lens and IMMEDIATELY rub with the cloth before the breath fog has evaporated. Repeat for the other side then both sides of the other lens - four separate breaths and rubs in all.

The first one of these cloths I ordered worked really well but for some reason these don't work so well. My first clothe I had for almost a year before it stopped working. These ones don't work so well I still get a bit misting on my glasses.

The good bit - it's a simple cloth with easy instructions (clean the glasses, fog them up, and then gently wipe off the fog).The bad bit - it doesn't work! (See image taken after rubbing with the cloth several times.) There's no discernable difference in the amount of fogging, other than some hints of swirls where you've rubbed. I tried rubbing gently, rubbing a bit harder, rubbing many many times, nothing improved the result.I normally use Muc-Off anti-fog which works brilliantly (note if you do try Muc-Off, the trick is to wipe most of it off) but it's a spray, and I wanted something simpler and cheaper. This is not it!

As I will not be putting bulky packet in handbag here’s hoping it will still work kept in smaller packing

I have bought these a couple times, as they don't last forever. However, they are amazing at keeping my glasses fog free, so handy in winter. And it wil last time you wipe your glasses again.The price is definitely worth it for these, I would be lost without them and probably a lot more frustrated, they stop glare and fog. Can't emphasize how much I love this, it has instructions of how to use, follow them and you can't go wrong.

The media could not be loaded. Edit to say that I have tested my kettle theory and it works! As you can see they are fully steamed up, after the first wipe for some reason only one lens is for free but after the second wipe they are fog free and remain fog free. Hope this helps!This cloth was recommended to me by a fellow glasses wearer and it is the best thing I've used for anti fog. I've used the no fog stuff from boots which in my opinion is utterly useless and I had all but given up. The first time I used this it didn't seem to work and I'd get patches of fogged up lense. I breathed on the glasses to fog them up and wiped and the results were not perfect when mask wearing they were still fogging up a little. However, I take my daughter swimming to a private indoor pool which is always extremely warm and my glasses are fully fogged as soon as I'm in the door. I gave them a wipe with this and they remained fully fog free for the duration of the lesson and I noticed they weren't fogging up the following day when wearing a face mask.It would seem they need to be heavily fogged before wiping to do the trick. I wonder if boiling the kettle and holding them over the steam and the wiping will achieve better results on a day to day basis when a swimming pool isn't available! I'll check and report back!
