I just go without my glasses. My husband has found the masks with the wire near the nose are better for him. He can sort of pinch them around his nose and prevent the air from coming out that way and fogging up his glasses. I haven't had him try any of those anti-fog products. I can't speak to all the current casino policies, but CET did specifically say that a mask would be required behind a face shield, unless there is some underlying medical condition.
