Look into the Zzipper fairing. Fits on your bike, not your face. Deflects air over your head anytime you are going fast enough to matter. You get to look over the fairing, not through it so it doesn't matter how wet it is. It has other advantages also. It breaks the wind and acts like a rider ahead of you, ie making our ride as easy as if you were drafting somebody. Makes long commutes significantly faster or easier, especially in headwinds. It also is a full layer of clothing warmer. Hands stay much warmer. ( https://www.zzipper.com/index.php go to Products, then Upright Products.)

I rode the Zzipper through Massachusetts and Michigan winters and wet Seattle winter (riding 15 miles frequently into storm winds from the south). (I also rode down Juaquim Miller Road into Oakland from Skyline in s a winter storm. Dried my glasses before I started down and rolled into Oakland with them still dry, seeing the road from above the fairing the whole time.

Those fairings look dorky but they really work.
