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.


I would be glad to. Pastuer suffered damage to his left (?) eye, it was
reported by all the matrons who were his hosts at very gala dinners. Person
after person has left the ranks of pathologists, cytololgists and other
trades after using poorly thought out binoculars. There are scores of early
pathologists who gave it up because it was to much of a strain. Nothing
could be done about it and people died earlier than now. I have seen the
damage done by poor design and thats modern poor design, not monoculars.
Problems like 2-3 cervical vertebrae, carpal tunnel problems and lower back
problems. I've seen at least 35 of these quit in my career, I knew them and
the problems they had.

Look, if you want to use a monocular, do it. Don't recommend monoculars to
any one covered by CLIA, its a big time violation. A lot of my friends and
colleagues in this craft wonder which company is going to get sued first,
were spared because no one who is an attorney even knows were out here.

As a physician I would recommend that you look into safety and health issues
in the lab, you'll be amazed and frightened. Monoculars are the least of
the problems.

Responding yet again to my own thread without anyone else actually
posting anything, one thing that I'm concerned about with stereo
microscopes is that we do already have a pair of Pentax
"Papilio" (spelling?) "extremely close focus" binoculars. So for
examining insects and the like, they do a good job. And if the purpose
of some low power stereo scopes was to do more or less the same thing,
there might be some duplication involved.

If I bought a higher powered monocular scope, then if preparation of
slides is a problem, it seems possible to buy prepared slide sets,
which might be enough in themselves.


Lets makei it clear, monoculars are a disaster. They can damage parts of
the eye. As a pro I've never actively sold a monocular since I deal with
colleges, health care and industry. Monoculars are yesterdays news, no
one
seriously uses them.

Now, don't buy new, buy used. For stereos try this web site
(www.capovani.com/dp/cat/107/63160/ilist.cfm?LCl=342&menuid=m_2_2_1) and
this one

(spectraservices2.american-data.net/Merchant2/merchant.mvc?Screen=CTGY&Categ
ory_Code=UMICSTEREO).
There are some very good dealers out there, pick one near you, these are
just suggestions. The real fun for a child is taking the stereo with him
as
he/she walks around your yard. The other problem with compound
instruments
is the distance between the eyes, its very small now and most 'scopes
don't
go down to that small size. But a stereo can be enjoyed at any age.
