I have an older version of these nothing I have tried comes close to working as well.
I had surgery on my right eye my tear duct was replaced with a glass tube. So with evry breath I take I part of it goes through this tube producing a cloud of fog on eye wear.
Dont know how serious you are these do cost a bit & colder air will be drawn in but Ive not found it to be that big an issue
