Optical Question?


#1

Greetings, I am having an optical problem, one of my trainees can not
use the Optivisor due to needing her glasses to correct a sever
astigmatism. Does anyone have a suggestion on how I can get her a
way to get the magnification that she needs to do jewelry work? Thank
you, Jim Revells Sudden Service #5 Natick, MA

Hi Jim, I use an Optivisor over my prescription glasses. Is there
any reason why she can’t do this? Beth

Greetings, Well other than being about the thickness of Coke bottles
& having a sever astigmatism they are about the same as mine. She
has complained that the items are a blur with or without the glasses
when using the Optivisor (I use mine for everything at the shop).
She is having a problem though & I want to keep her (dependable
trustworthy people who want to learn, not being an asset that I like
to give up on), but if she can’t see she is not going to be able to
work a shift by herself. The Optiviser fits over her glasses, I have
#5, #7 & #10 plates & can order a couple of more from DRS next week
to try that possibility.

We are a jewelry & watch repair kiosk in a mall, that has lots of
high end watches come in. This really requires using a Optivisor or
equivalent to work effectively (ever try to see the battery hold down
screw on a ladies Longines?-SMALL). I will see if the clip on set
will work, but I am pulling my hair out over the problem.

Yes, this is Olaf’s Mundane World persona & it is Phlip from the SCA
EK Metalsmith’s list we are talking about. I have 3 trainees who are
all SCAdian (one of my apprentices is a Laurel in Blacksmithing),
guess which two weeks in August we all want for vacation? <;^}

We are looking to expand the locations up here in New England I am
having to train more people, so far all I have found have been
friends who are blacksmiths. I have a choice: I can either find
enough people to work 3-5 stores & be the relief/district
manager/fill in when no one else can person; sell the one location we
have up here & be unemployed while attending school; or close the
store when the lease runs out in 19 months, which is when I am
starting back to school at the Worcester Center for Crafts School for
Professional Crafts (Metals) again. I went one semester before my
previous co worker quit & I had to take a leave of absence from the
school. So if any of you know people who are looking for work in
Eastern MA or NH, send them my way.

Pax,

I wear my glasses with the optivisor. I have severe astigmatisms
and never even thought about not using my glasses.

Jim - I see what the problem is. You need either the #2 or #3 plate.
I’ll bet that she is using the higher numbers and still trying to
focus at arms length! The #5 focuses at about 12" or so, and #7 is
about 9" and the #10 is somewhere around 6" (I’ll post better numbers
on Monday when I can get to my files).

It’s not the astigmatism that giving her fits, it’s that she hasn’t
found the working distance focus point yet. Back off on the power
with a lower number plate and all will be well.

It should just be a matter of getting the right lens for the
optivisor. I would suggest consulting an optician and see what can be
done. And if this doesn’t work, then you may have to resort to one of
those magnifying lights; it can be adjusted to the right distance so
that she should be able to focus it to give a good picture. Or, even,
as a last resort, some special spctacles that she can use just for
this close work.

Hi Jim, My suggestion would be to have your employee take her
glasses and Optivisor with her to see an optometrist or (better)
ophthalmologist. I would guess that this is an idiosyncratic vision
problem which needs an expert to solve it.

    I have a few options to offer for your student. 

One consideration would be corrective surgery that can now correct
astigmatisim but would not help with her magnification needs. I use
Zeiss Lenses for my general work during the workday. These are the
equivelent of a # 7 optivisor or slightly better. With a wonderful
working distance of 11 " and are very lightweight. They correct both
my far sighted issues and need for reading magnification so nothing
else needed. I buy these from Miller Optical in Texas and have been
very happy with them.I believe they are also available in a lighter
power.

I also use surgical loupes from Design for vision in N.Y. These are
larger and heavier telescopes and I wear them for fine detail work
only but they also contain my needed script ( optional ), and the
combination of the two answers all of my needs.They also make the
smaller lenes @ lower magnification with or without script included…
It also seems to help to keep the " Pop " in the greater
magnification as I noticed a few years back that if I wore the
stronger magnification all day, my eyes would over time seem to
adjust and I would loose some of the power somehow. I can’t explain
this medically but this is what I found happened.

This is another area where our trade falls far short of
professional. To think that for the majority of the trade the typical
answer to this need is plastic lenes with a terrible working distance
and fixed pupilariy distance, as if all our eyes are the same
distance apart.This creates terrible strain on our eyes and over the
course of time I believe bigger trouble, and this in a trade where
our healthy vision is so critical . Sorry to ramble a bit but “your
eyes” are worth it. Peace Karl

The problem with the optivisor over glasses may be an issue of the
"sweet spot" of the glasses not matching up with the optivisor
lenses. I wear seamless trifocal glasses under an optivisor. I have
to look through the bottom third (close up section) of my glasses
with the optivisor lenses swung down low in order to do close work.

If your employee has to look through the center portion of her
glasses, it might mean that she has to tilt her chin down, slouch or
else slide her glasses down her nose to see out of the center while
working at a bench pin or down in her bench pan. None of these
options would be uncomfortable and all would be damaging in the long
run. She may need to figure out what her working position is and get
glasses with a specific “sweet spot” made. These glasses probably
wouldn’t do for regular wear since most of us don’t spend our lives
looking downward.

HTH shed some light on the problem.

Here are the plate numbers and magnification powers and working
distances:

Choices of Lens Plates

XX		working dist.		diopter power   Magnification
02		 20=94				  	+2D			1.50X
03		 14=94				  	+3D			1.75X
04	  	 10=94				  	+4D			2.00X
05		  8=94				  		+5D			2.50X
07		  6=94				  		+7D			2.75X

I have found that I am unable to wear “graduated” bi-focal lenses
while working, so instead, I had special lenses made up, they
consist of two different “close up” distances. The upper allows me
to see what is on my bench, the lower allows me to see things close
up. I can wear these with an optivisor and not worry about finding
that “sweet spot”

I wear seamless trifocals, and I use the Mag-eyes magnifier. I find
it to be very adjustable. I can look through any part of the
trifocals I need to and still use the magnifier. And its open design
means the top of the magnifier doesn’t press down on my glasses and
make a dent in my nose.

The makers of Optivisor have come up with a new product it is called
the Optisight. This is lighter with a slip on Head Band.

Optisight has an open front with no hood and comes with 3 lens &
costs the same

They may be a good solution for your problem about light & fitting
over the glasses

Two disadvantages are that the lens are made of Optical Acrylic as
oppose to glass. The Optisight is very light the head band does not
have the tightening knob.

From our sales experience it has been a good product but the actual
Optivisor still outsells all others by atleast 3:1
