TUSA Anti-Fog Freedom Film for all Scuba/Snorkeling

Produto ótimo, eu usei agora no mergulho que fiz, realmente a máscara não embaça, é um pouco caro o valor mas vale a pena o investimento, recomendo !

Other reviews moan about them not fitting. I am not sure these people should actually be scuba diving or snorkeling. Common sense and a modicome of intellect, you rotate both inserts until they fit. I purchased for my new MARES X view mask. I had used sea scrub, as I don't like to burn the lenses. Still the first day of my trip my mask suffered some fogging. So I re-applied the sea scrub and after rinsing and allowing to dry I used an isopropyl alcohol wipe and fitted the anti fog inserts. They work really well, although you still get fogging around the outside of the inserts. The issue I had and why I marked it down a star. They could include a sticky tape, as they do with mobile phone screen protectors. To dab on the lenses and remove dust particles. If you have even the smallest of dust, salt or sand particle inside the mask it will cause the film to have a bubble. Whilst these do not actually effect your vision when diving, for me it is annoying. Now home I will order another pair and fit them in a well steamed bathroom. so the steam removes most of the dust and I will use some of the sticky stickers left over from a phone screen protector.

When they finally arrived, threre were 2 right eye lenses and no left eye lenses. I put the one in the right eye so I can test it. So far, I can't say how well they work since I have only been in the pool with students.

Don't work very well to be honest. I don't recommend this product.

I constantly have problems with my goggles fogging up. I have tried so many tricks to try and stop it. When I read the reviews here I was skeptical. However, it just works. I have had no issue with fogging at all. Sometimes I can even see the edge where the film isn't and it will fog there, but the rest is clear! Definitely worth the buy.
