okay first i will say sorry for my ignorance as there have probably been hundreds of similar threads . anyways , i am having lots of trouble with my mask fogging up on me even out of the water it just fogs up like nuts and then i cant see a thing . does anyone have any advice on the subject , like tricks with breathing , anti fog solutions , or any thing. thanks and good day :head
 
okay there are two things to keep in mind: the one-time anti fog treatment for a new mask (I will explain below) and the everyday treatment before each dives, that consists in spitting on the lenses and wash them in the water just a few seconds before wearing the mask for the dive.
Now the radical one-time treatment for a new mask, in two different fases which are both to be done: lighter and toothpaste.
1- get hold of a cigarette lighter, and pass swiftly the flame on each surface of the lenses, taking care to pass very quickly the flame in order not to burn the silicone skirt. When done, rub the lenses with a dry towel.
2- rub the lenses with toothpaste using your fingers (not a granular paste, but a smooth type paste in order not to scratch the glass), then leave the toothpaste on the lense for one whole night (at least 12 hours) then wash away. If it doesn't work, try again the day after.

Since start diving I used few different masks and spitting on them inside the lenses and washing them after few seconds it has been always the right thing to do.I also used a product (antifog staff )but never been better than a natural saliva.
 
After doing all the above, if it's still happening, then you're not controlling your breathing properly. What happens to noobs sometimes, especially on scuba, is that they do not isolate the nose from the breathing cycle, and the mask air is constantly pumped in and out.
If that's the case, make sure that when you are breathing up, you are only breathing through your mouth.

There's no real need to isolate the nose from the breathing cycle - as long as the mask has been properly readied before the dive then it shouldn't make any difference to mask fogging. However, it might turn out that people who don't isolate the nose in general will be less experienced, and so are less likely to ensure that the mask has been prepared properly....
 
If the lenses are plastic, make a note for the next mask you buy and be very careful with toothpaste. Another old time favorite is to bring home a bucket of sea water (or make your own) and leave the mask in it for a week.

I taught hundreds of scuba students and this happened all the time unless it was corrected. Perfectly cleaned and prepared masks fogging non-stop.
So from that I deduce that there is in fact a need to isolate the breathing, plus not doing it also shows lack of control in this area that is fairly important to a freediver.

I wasn't saying that control was a bad thing - just that it's not essential when thinking about keeping a mask unfogged... I'm an instructor and working diver as well, so I've got a fair bit of experience, but I wouldn't say that this is a major contributor to fogging (it could do something, and I think it's very possible that it could exacerbate an existing issue)... The biggest problem that I've noticed is getting the mask wet before spitting to add the defogging layer... If the mask gets wet first (especially with saline water) then it's very hard to effectively coat the lens to prevent fogging. This does tend to happen a lot with new divers so it's something I try to point out in beginner classes...
