Dear Kevin,

I have seen you write many times that monocular observation
damages the eye(s).

I am a physician and can't imagine what the damage might
consist of and what may cause it.

You are certainly aware of the fact that all the pioneers
of microscopy, bacteriology and biology worked with
monocolar scopes and did not suffer any damage. Or
am I wrong here?

Would you be good enough to comment.

Thank you
GR.

Actually Pastuer had problems through out his life caused by monoculars.
I'm sure other microscope pioneers had the same problem but in old days that
was all there was so you either sucked it up and used the monocular or you
got a new job. Sale of monoculars is forbidden by the feds for hospital
labs and pathology.

The big problem is learning to use a monocular with both eyes open. Some
people can do it and others can't. Take a look at old microscope catalogs,
there are lots of "blind cups" shown. This was one way to use a monocular.
Some people like Pastuer had problems since their non-dominate eye had to be
closed. Through out Pastuers life he had a twitchy left eye.

In training classes you are instructed to stay away from monoculars for the
above reasons and since none of us want to get sued.

Thanks,

Interesting. As I have something that could be described as a "twitchy
left eye". I get a strange feeling in my left eye sometimes, which I
can feel now, like a very small muscle is in spasm underneath the
eyelid. It comes and goes. I haven't worked in a lab or anything,
though I had a monocular microscope as a toy when younger and did do
an undergraduate degree in Cellular and Molecular Biology (though I
moved to another subject for my graduate degrees), so did spend quite
some time looking through microscopes. I've always considered the eye
thing to be my indicator of when I'm experiencing stress, and have
sometimes felt a similar thing in my thigh muscles.

Hence I'm now much more interested in finding references on this than
I was before.
