In the 80/90s my mum had a pair of sunglasses that had a channel in them that connected to a portable air filter that.
It basically pumped filtered air into your eyes and stopped the pollen getting in.
They had a channel from the arms of the glasses that ran into tiny holes in the top of the lens frame, flexi pipe would run from the arms down to a Walkman sized air filter, battery powered, air filter - it was just a air pump that sucked in the air and ran through a little filter.

They finally broke a few years ago and I haven’t found anything like them since.
Is this something that could be made?
