I wonder why you have such a problem with fogging? Do you work in a very cold environment? Are you running or moving around to the point where you are constantly sweating?

I think the fogging occurs when there is a great enough temperature differential between warm air close to your face and the lens and the air outside the lens. Maybe if you move the glasses a little further from your face? If you can isolate the air inside the glasses from the outside that may reduce or eliminate fogging. You might benefit from goggle style rather than a glasses style?

Just a thought.

This is most likely the cause of the fog up. It’s the change in temp between the glasses and the air between them and your face. Moving them away from your face will help alleviate the problem, but then you run into issues with objects being able to get underneath them to your eyes.
