I have a pair of tinted Smith shooting glasses that work perfectly--they wrap around the side of my face quite a bit, but are nicely open at the top, bottom, and sides, which allows all of the condensation from my mouth/nose/etc to dissipate quickly.
Remember, the reason you get icing and fogging is because warmer, moister air suddenly cools down and condenses on the nearest available surface. Your priority is to make sure that the warm air gets removed before it can do that.

There are two ways to combat this - prevent the warm vapor or move it past the lens via circulation. The former requires either not using eye pro or not cycling.
The latter requires the use of vented or open lenses.

+10. I have replied to so many threads on the fogging problem advising that solution, that it’s becoming too exasperating to keep up the replies; same for the anti-fogging agents.

A pair of simple, wide, plastic industrial goggles that I suspend from my cycling cap using Velcro around the nosepiece. The goggles sit very comfortably on my face securely in place even though my ears are covered. The earpieces then provide a secure mount for my eyeglass-mounted Take-a-Look mirror....
The windscreen of the goggles is so effective in keeping my eyes warm that my eyelids actually perspired because my central core body was so warm, and
my eyes never got cold, even on those fast windswept downhill runs. The goggles allow sufficient room for my prescription eyeglasses, and are
widely ventilated to carry away the exhaled moisture preventing fogging...
I have also often suggested that any recommendations for winter riding include description of the conditions in which they are employed, i.e. lowest temperature and distance….
