I've had real problems with clearly seeing signs on my previous Honda VTX 1800. I wear bifocals and have Scorpion EXO helmets with "KwikFit" pads for glasses. I could see okay but not read street names of road numbers until it was too late.

Changing to the F6B with the 12" Baggershield windshield fixed everything. No problems now at all.

I tried bifocal and monofocal contacts for several weeks each, but just never got used to them.
