Permanent Ant-Fog coatings have never made it in our field, because of the following reason:

A hydrophilic (Anti-Fog) coating gets ineffective after 4-6 month of use because it saturates with humidity and the stops being effective. There was one invented in Japan a few years ago, but only worked 4-5 month and was retired from the local market.

Knowing from my MicroTints system that microwaves can do some chemical wonders altering molecules in cert aim materials I have come up with a humidity cure coating material that is easily applied in an office environment without expensive equipment. The coating does superbly adhere to un-coated or hard coated lenses from CR39 to High Index.

The ultimate test to check the effects is the freezer test, by placing treated lenses into a freezer for 30 seconds and then removing it to room temperature. If treated properly the surface will stay clear and will not fog up on the treated surface.

This coating will also saturate after a certain time of use and stop its AntiFog properties. These properties can be renwed by placing the lenses into a microwave and expose them for 60 seconds of high power. The lenses will get warm and after coooling off are again fully active and will have renewed anti-fog properties.

The final layer is hard slippery, super hydrophobic and hydriphilic athe same time and also acts as an anti scratch treatment.

It will not work on AR coated lenses as the layer is too thick and alters the AR coating properties.
