Winter eyewear?

[John Rose]

... The brim lets me see toward a low sun. It deflects cold, bugs, and rain away from my eyes and face. ...

The sun is one of my biggest problems, especially heading west late in a winter afternoon. Before switching to my winter helmet, I was wearing either a ball cap or one of those tennis visors under the regular bike helmet.
I think with the winter helmet I'll gorilla tape a visor made of black craft foam to the front.
