I'm now using the stick-on Optics on some Nashbar cycling sunglasses. Got one pair of the Optics, cut them to fit and put one 'stick-on' on the right side of the dark lenses and one stick-on on the right side of the yellow lenses so I can read the speedo. They work pretty good. But have to carry regular dollar store cheaters to read menus and change flats. No biggie there, but having cheap corrective sunglasses would be nice for cycling and other things.
Thanks.
Just saw this so will bump it up again.
For the last several years I have worn no-line bifocals. I don't find the transition from bifocal and plain lens to be a problem.
I go from looking at the computer/heart monitor to focusing above the bifocals on the road ahead. Its not like a car or in an office where you are switching your focus amongst a paper in your hand, the guy across your desk, or the whiteboard on the other side of the room.
Its basically bifocals close, and everything else is far.
