Winter cold question

Figured I would ask here to see if anyone had recommendations. With the weather getting colder, I feel my prosthetic is getting colder/dryer. Theres been more buildup of mucus that then dries and gets really uncomfortable. Ive tried using artificial tears/oil but that doesnt work the greatest. My thought was a thermal eyepatch, but not having much luck finding one like I picture. Anyone have any advice or success?
