Many recumbent riders swear by DaBrim visor products to keep the sun off the face. I have never tried them but given the universal love for them in that world, I thought I would pass that along. They make many different models to keep the sun out of your eyes or off the face. Could maybe used from say 10-4 when the sun is the worst and then stowed?
