Cyclometers & presbyopia

I agree that this idea has great originality, and I would like to carry it
one step further, before I shoot it down. If you already have a rear view
mirror on your bike, helmet or glasses, you could make this the first of the
two mirrors in the sequence. Now, the fatal flaw: a mirror gives you a
very limited angle of view--two mirrors in sequence would require your head
to be in an exact position and angle to even see the cyclometer face.
Difficult to do while riding. It would be like trying to read through TWO
knotholes. BTW, your monicker, "Foldedpath" seems to be relevant to this
idea

The fresnel lens idea seems most practical to me. The
idea of affixing a temporary plastic bifocal element also
seems very do-able. I ride with trifocals and have no
difficulty at all.

Yeah, this rules out the attractive idea of co-opting a road
mirror you're already using.

It's tempting to use the triangle arrangement of the frame
as a way to mount the cyclometer and two mirrors, if you
could work it in around the bottle mounts, and not interfere
with your legs when pedaling. Did someone say "Rube
Goldberg?"

Oh yes. That handle started in an amateur astronomy
newsgroup. I like big amateur Newtonian (folded light path)
telescopes. If you want to research wacky multiple mirror
setups, telescopes are where most of the wacky ideas have
been tried.

Eventually I'll probably be forced to solve this at the
eyeball end of things, with prescription sunglasses or
contacts. But I'm going to try a few of these other ideas
first. The fresnel idea sounds good. Not looking at the
computer until the end of the ride, also has some appeal.
