big fan of clear lenses. only wear shades when I know I will be in full sun for the whole ride. polarized vs no polarized less of an issue, but if I have a choice I'll go w/ polarized due to the inherent features & benefits. just got some non-polarized glasses at a flea market for $10. I liked the design & form factor. meaning slim design & no lower or edge frames which obstructs my peripheral vision
