I'm a member of the very nearsighted club too. I worked my way through the local optical shops until I finally found a pair that would work. Early spring is the best time to shop because that seems to be when most shops have the best selection. Mine are Columbia Brand and were in a display for motorcycle frames. FWIW: I definitley would go with a bifocal if you need it. The first pair of perscription sunglasses I got, I didn't think I would need the bifocal. But my distance perscription is so strong I can't see close with the glasses on, which means I had to take them off to do anything close. Like read my Garmin, order from a menu, see the gagues in the car! The second pair has the bifocal, which made it harder to find a frame but SO worth the wait.
