I wear regular perscription glasses...ohh the horror...bifocals (got blended lenses for my vanity) and use Solar Shades from your local Rx store for $19...or your favorite fashion French retailer Tar'get...cheap for everyday riding.
But, being the "backup" guy I am from years of going through "what can go wrong will"...I carry "Guard Dogs" with removable lens - NON POLARIZED for long term road, heavy duty use.
Polarized lenses are dangerous, can mask those tar snakes or empty manhole covers on a sunny day and really cause rainbow effect thru your windscreen...be careful what eyewear you use and if they distort your vision, get scratched or hazy pitch them!!!
