Sun rise or sun set, either situation is obviously a risky time for riders. Hoping the drivers will be able to see you....
I ride home pretty much every day into a rising sun.
My helmet does have a tinted drop down shield to look through - but that just darkens everything, including the shadows.
I prefer to apply a strip of painter's tape before setting out....
Blocks the sun, without hampering my view of things.
