Many helmets come with snap on visors.
I hate wearing helmets because they don’t have a visor and I get the glare over my sunglasses. Much prefer a baseball cap with a visor, but I know I’m risking my noggin every time I go out on my bike. My biggest fear is the college-age women who are yapping on their cell phones and looking to the left as they run right through a stop sign and will turn right into you. I keep outta da way of those dingbats if I can and prefer to stay on the canal pathways versus the roads. But even on the canals, you have to cross with the cars at intersections.

Go to an equestrian supply store.
There are numerous forms of helmets for jumpers and polo players. They are fiberglass with a velvet covering.
They have visors, but not quite as long as a baseball cap.
There are also helmets for race horse jockeys.
Anything would be better then those fruity bicycle helmets.
Educate yourself. Helmets designed for road bikes (those with drop bars) don’t have visors because the lower riding position would necessitate lifting your head at an uncomfortable angle to see past the visor. Mountain bike helmets on the other hand almost always have a visor because of the more upright riding position.
