Ek Cat Crap Anti-fog

So far so good, put a small amount on each side of my lens’ and I’ve not really fogged up with a mask on and I wore my glasses normally.There was a little misting when going from outside (cold) to inside (warm) but it dissipated quickly and without the need to wipe them.

Simple and easy to use. I use it all the time and I wear glasses inside my motorcycle helmet.Worth every penny!

This is a very useful product with a very unusual name 🐈‍⬛

Sadly did not work as well as it claims. There was perhaps a very slight improvement in the fogging on my glasses,but not enough to justify the price and won't bother with it again. Maybe it works better in different temperatures?Not for me though.

Does as it say on the tin. Rub a health amount in to my airsoft lenses played all day with no fogging

Treated one lens of my specs and tried breathing out on both lenses. I couldn't see any difference in fogging between the two.

GLASSES DO START TO FOG UP AFTER ABOUT ONE HOUR. WHEN WEARING A MASK. BUT IT WORKS BETTER THAN ANYTHING ELSE I HAVE TRIED.

Optician recommended this but found it cheaper on here

Hello,I am not one to write poor reviews, but in light of Cat Crap Lens Cleaner, I must. I am an Emergency Dept. Nurse. With COVID 19 I use Honeywell Uvex Stealth OTG Safety Goggles with Anti-Fog/Anti-Scratch Coating (S3970D). These google are purely business and meant for keeping airborne pathogens out. They fog up. So I bought Cat Crap, and applied as directed. During a suspected Covid-19 code, I used my googles. By the end of the code, my goggles were a fogged up dripping mess. I tried again and again, per the instructions to the letter, to see if I had made an application mistake. Nope! Fog.... So, I got a different pair of UVEX googles. Fog.... Tried a different brand of goggles, used Cat Crap..... *&^% FOG!!!!! I cannot afford doing codes and being blindsided with fogged goggles. So, my advice is to for any medical pro or someone needing full seal googles to avoid Cat Crap. Sorry EK USA. The product let me down time and time again.

After reading other negative reviews I felt as though I knew better and that they were just crazy or didn't know how to use it. Do yourself a favor and listen to these reviews! You will be money ahead by just buying a stick of chapstick and smearing that all over your glasses/goggles. This product does absolutely NOTHING to address or alleviate fogging on lenses. It is amazing to me that they are allowed to continue selling this! In fact it will leave little bits of blue Cat Crap in the corner and against your nose piece that are difficult to get out. You'll thank me later and you're welcome.

I was skeptical at first. I recently started cycling 15 and 20 mile rides just before dawn and immediately had a problem with my glasses fogging up when stopping at intersections. The night before each ride I just apply a fingertips worth of cat crap, really, the tiny eat amount to each side, of each lense. Spread it around until they're all cloudy and then wipe the lenses with a microfiber cloth or paper towel until clear. At this point the lense won't fog up; even if you breath directly onto it. Would probably last a couple days but it definitely needs to be reapplied regularly.I can't stress enough, you only need a very small amount on your fingertip. The small container will likely last me years.

I've been having problems with my glasses fogging up while wearing a face mask. This stuff really works to keep most of the fog away. I'm really eager to try this in the winter, too!

This stuff is aweseome. I saw a demo for it years ago at bike week. Have used it on motorcycle helmet visors, safety glasses and with the recent need for masks causing my glasses to fog up, i found it again.
