I have read that if you have them before your eyes for a couple of

actually upside down so the turning back has already been done once

I remember hearing about some scientist who did this back in the 60's or
70's. His brain learned to accomodate the world appearing to be upside
down but when he went back to living without the goggles, he had some
sort of a mental breakdown because his brain could not handle the stess
of changing back to the right-side-up world.

Apparently it doesn't matter if the image is coming from your eyes or
somewhere else, your brain will let you see it. I don't have the
article on me now, but I remember a doc being quoted saying something
like, it doesn't matter if it's coming from your eyes or your tongue,
a nerve spike is a nerve spike.

They were looking to use this to help the blind "see" and to help
pilots get information from their instruments without having to look
down.

Wouldn’t it be awesome if you could be unicycling and be able to "see"
what's going on in back of you via a camera and your tongue?

I don't know what your body's shaped like, but you have to consider
first where your legs will be, and second where the mirror is supposed
to get a look through. I don't think there's a clear shot anywhere in
there.

My old "Excessory Cycle" had a mirror on it. I've attached a picture
below. Unfortunately you can't see the mirror in the photo. It's a
handlebar mirror, of the same era as the rest of the junk on that cycle
(late 70s, early 80s). My how things have changed since then! The mirror
is on the opposite side, approximately where you see the speedometer,
down near the fork crown. It was a rectangular mirror, which I mounted
vertically, snug against the frame just above the crown. No place else
to put one on the cycle and still have it even partially function.

This mirror, though you could see behind you, was not useful. You had to
look straight down to use it, and of course it had to be far enough down
to have a view between your legs. I don't know if this can work on a
Coker.

For mgrant: There must be mirror solutions out there for the millions of
cyclists who wear prescription glasses. I view my glasses-mirror through
my lenses. Of course this is on a pair of $8 sunglasses. I'm sure you
can find a mirror out there that will work with your glasses, though the
narrower your glasses are, the harder it will be for any mirror to get a
view behind your head.

I usually have to adjust my head position to see the road behind me.
When I'm in my "semi-tuck" position, the mirror can't get a clear view
behind me without me moving my head some. Then when I'm sitting up
straight it's a different angle to the road behind me, so I'm used to
the need to "aim" my head slightly to get a good view through the
mirror.

When it comes to helmet or glasses-mounted mirrors, I think you have to
allow for a period of adjustment and experimentation to find the right
position. Give it some time, and patience.

I had heard good things about the 3rd eye mirror that attaches to
eyeglasses. Last summer I got one to use for my Coker commute.
Unfortunately my experience is not as positive as JF and JC.

You see, I wear prescription glasses. In order for the mirror to "see"
behind me it had to be positioned such that my eye had to look outside
of my prescription lens.

I wear prescription glasses (or rather, cycling glasses with a
prescription insert) and get on very well with the 3rd Eye. Initially I
sometimes found that it fell outside the range of my corrected vision,
but after using it every day for a few weeks I was able to reliably
adjust it to fall inside my corrected vision.

I've been using them daily for nearly 2 years now and wouldn't hesitate
to recommend them for recumbent riding or unicycling. Just bear in mind
that they only last about a year before the attachment arm snaps.

I had a Heads Up mirror delivered this morning. I've only used it once
- first impressions are good, but it'll take a few rides for me to
decide whether it's better than the 3rd Eye. The big disadvantage is
that being made for the US market it's designed to mount on the left
hand side, for riding on the wrong side of the road. That's not a
problem with the 3rd Eye, because it just swivels round on a
ball-and-socket joint.

The OP might be interested in the ViewPoint mirror, designed to mount to
the lens of your glasses:

I think you could put one near the end of a rig like this.

Your rig is awesome. I need to set up something along those lines for
mine. I need a rack on the back, and a longer, lower handlebar. I want
to experiment with more aerodynamic riding positions. I imagine I'll end
up with a compromise between aero and not-falling-on-face.

So I guess you meant to extend a mirror way out to the side. Yes, that
would put it in major danger, not only on UPDs, but in average parking
and handling situations as well. I think something on your head will be
much more convenient, and easier to live with.

I recently had more or less the same idea. Mine is one of those little
convex stick-on blind-spot mirrors that goes onto the side mirror of a
car. I pulled the guts out of a broken wristwatch and stuck the mirror
onto the front, so I can mount the mirror on my left wrist. It's not
terribly compatible with coat sleeves and gloves, so I haven't had a
chance to actually use it outside yet, but I tried it in the gym at
MondoFest and it seems like it might at least be better than nothing.
Whether having to hold your arm up in a window-washing position in order
to use the mirror is harder or easier than looking back over your
shoulder remains to be seen.

Sounds like the 3rd eye works great and there are some interesting ideas
on hand held, or glove mounted mirrors. That watch idea is a good one.

Guess no one has tried these "spy" glasses, I'll order a pair, of
these: http://www.tbotech.com/spyglasses.htm 'modern' and let ya know.

In september 2003 I got hold of the little mirror which U stick to
glasses.
It has 40 degrees pivot adjustement.
For me it is one more gimmick but proper road unicyclist would like
it.
It gives good vision, no shacking and definitely can improve safety
level.
Although I have imported it from USA it was, OBVIOUSLY, made in China😄

The *-_best_-* rear view mirror I used is the 'Take A Look'
(http://gallery.unicyclist.com/album503/TakeALook) by Bike Peddler.
[image: http://gallery.unicyclist.com/album503/TakeALook]

Large mirror, not glass
Made, mostly, of metal so it won’t shatter when cold
Can be bent to fit your configuration; just don’t bend the brass tubes
Adjusts easily to -any- position (you can even turn the mirror to face
front!) and then stays there
Doesn’t shake like the others I tried (and trashed with out
replacements)
Will mount on most glasses or any helmet (the funny thing on the left is
the helmet mount, glues on, I've done velcro)
The helmet mount can be moved to another helmet (but not easily) or you
can get other mounts
Left or right side
Can be moved from a helmet to any glasses to any other glasses quickly
without any modifying
About $15(USD)

The only downside is the mirror can get scratched.

I tried the "spy" glasses. http://www.tbotech.com/spyglasses.htm .

It takes just a little getting used to, but they do work. You can check
on traffic with slight turn of the head. I'm planing to continue using
them, I like being able check back for cars.

Before getting these glasses, I had recently been fooled when two cars
approached me from behind and after one went by, I thought that was it.
Although it wasn't that close, it surprised me when I pulled out in
front of the second car. So I like having better vision behind myself.

The biggest problem is that the quality of the glasses is very poor. Of
two pairs, one has a dark streak across the lense, and both have blurry
mirrors on the right lense. Also since they are dark sunglasses, they
are only useful in bright sunlight.

I'm sure that if you don't mind wearing a mirror on the side of your
glasses or helmet that would be a better solution since it would work in
all light conditions and be less blurry. Me, I'm still reluctant to wear
the side mirror, because riding a unicycle looks weird enough without a
mirror sticking out the side of my head.

But I expect that I'll eventually break down and get the side mounted
mirror. It's better than making out like road kill.
