Permanent Anti-Fog Coating ............
I came up with a new coating that I would a few OptiBoard Members to try out. Any volunteers please contact me at oms_optical@yahoo.com , but please mark it on subject: line so it wont go into the trash folder.
Anti-fog coatings are known to get tired after a while and will not work anymore.
My new coating can be renewed by heating the lenses in microwave for 2 minutes, and they will work again like new.
(Do not heat the frame along with lenses.............just tried it and everything went up in flames......so remove lenses from frame)
You can check it out on my website at: http://optochemicals.com/paf_antifog.htm
Is this the same stuff?........................

They advertise it as a :
Thermal cure process with dip hard coat primer and Fog Free coating, 2 day turnaround
TINTS cannot be coated at this time
My stuff is a humidity cure copolymer you can apply it on any surface you want and do it in about 5 minutes. The only condition is that your lens or coatings can take the heat in the microwave for 2 minutes and AR coatings can not be done as it would be covered by the coating and become ineffective.
Waiting for some results....................
I am still looking for any results from the ones that were going to test the product
anti fog......................

The wetting is enough as you describe, but you do not say if you even did the next step, which was to wet the lenses again and then place into a microwave oven and heat at full strenght for 1 minute, only then the coating becomes 100% anti fog.
The question is really, once properly done how long do they stay anti fog, 2month or 4 month. Then they can be wetted again and placed in a microwave for 1 minute and they work again as before.
Finally some answer..............................
Got This in my e-mail today

Actually it just happened that Canadas largest Safety Optical has started to supply it on lenses.

If it could be done, you would get another problem ......................
Scratches have removed some of the coating materials and by melting the coating back together with heat you would create a wavy surface which is a no no, on Rx lenses..
