The Lost Art of
Eyeglass Adjustments |
 |
There is a commercial currently running on local TV which
is enough to make proud opticians of days gone by roll over
in their graves.
The voice in the commercial is informing
about the “…best value in eyeglasses…two pair for $99…”
while we view the action on screen.

Picture this: A young,
female patient/customer is sitting at a dispensing table,
awaiting delivery of her eyeglasses. The dispenser brings
the glasses to the table, hands them to the customer, who
places them on her head. The “optician” seems to ask a
question of the customer, who smiles, shakes her head yes,
stands up and makes her exit. That, apparently, is the end
of dispensing process. But should it be?
When my wife, Andrea, graduated from Opticianry School in
the 1980s, personalizing the fit and adjusting eyeglasses
was a huge part of the curriculum. Likewise, while I was
completing my three-year apprenticeship, more time was spent
teaching me the intricacies of adjusting eyeglass frames
than any other aspect of opticianry. Fast forward thirty
years later and I am afraid that the approach to adjustments
(in terms of schooling) has taken a back seat to nearly
every other aspect of opticianry. Apprentice sponsors gloss
over the topic. Saddest of all, before attempting any
adjustment whatsoever, many eye care professionals feel the
need to ask patients a question that no dentist,
chiropractor, or other caregiver would even think of: “Is
it okay if I touch you?”
I am also a big believer in giving credit where credit is
due, so I would be completely remiss if I did not inform you
of the inspiration for this article. It came from a
dedicated colleague for whom I have much respect – Hari
Bird, a proud, dispensing optician since 1958. The quote on
the website he created says it all: “It is how well the
eyewear makes contact with the patient that ultimately
defines ophthalmic dispensing, whether it be spectacles or
contact lenses." I would encourage everyone interested
in a good refresher course or for people who are studying
the profession to check out his website and the home-study
course he has created at www.opticianrytoday.com.
Unfortunately, an article of this nature cannot
adequately address the problem, nor effectively teach the
methods and techniques that must be mastered to be an
effective adjuster and dispenser; but we can point out the
various things that must be known and the problems that must
be addressed on a day-to-day basis in the dispensing world.
Ask yourself, are you and your staff members able to
adequately deal with some of the following issues? The
challenge/problem is listed and in parentheses are some
possible causes.
-
The glasses do not stay in place. (Temples spread too
widely; temple adjustment behind ears is too loose or
incorrect; pads spread too far; bridge too wide; doesn’t
fit nose; eyeglasses are too heavy.)
-
The frame sits too high. (Bridge is too narrow;
distance between nose pads too small; pad arms too low; poor
overall fitting.)
-
The frame sits too low. (Bridge is too wide; distance
between nose pads too far; pad arms adjusted incorrectly;
angle incorrect.)
-
The frame touches the eyebrows. (Temple angle is too
retroscopic; poor overall fit.)
-
The outer ear hurts. (Temple rides too high on ear;
temple touches ear cleft; temple touches lobe of upper ear;
temple tip touches outer lobe of ear at the bottom of the
lobe.)
-
The head hurts behind the ear. (Contact area is too
narrow or small; temple tips “dig in”; temples too
narrow or tight against head; temples are too short.)
-
Temples wobble or flop open. (Patient has a screw
loose {J}; rivets loose; rivets broken; internal spring
mechanism broken or about to break.)
-
The temples are too long or short. (Poor fit; lazy
fitter.)
-
Vision seems “off,” but was acceptable at initial
dispensing. (Prescription filled incorrectly; prescription
ordered incorrectly; error in vertex fitting in strong
prescriptions; base curve incorrect; defective and/or warped
lenses; pantoscopic tilt is incorrect; face form is
incorrect; unwanted waves present in lenses; scratches.)
-
Vision problems occur at near – especially with
progressives. (Prescription incorrect; frame too high or
low; O.C. placement incorrect vertically or horizontally;
reading area is too small; fitting height incorrect;
incorrect brand was chosen for patient; objects “swim”
or move when wearer turns head.
-
Wearer is having problems in adapting to the
prescription (Incorrect prescription; fit does not match old
eyewear.)
-
Wearer is having problems adapting to the
frame/adjustment. (Wearer is switching back and forth
between the new glasses and the old; not wearing the glasses
long enough to adapt; bifocals located in different place
than old pair.)
-
Vision is unclear at specific working distances.
(Patient needs bifocal, trifocal, or progressive lenses;
wearer’s visual needs have changed; glasses not being used
for prescribed purpose; segment or fitting height is
incorrect; the near addition power is incorrect.)
-
Wearer is experiencing unwanted reflections and/or
ghost images. (Glasses need more or less pantoscopic or
retroscopic tilt; base curve needs to be changed; lenses are
uncoated (AR), especially in polycarbonate and high-index
lenses.)
-
Wearer is experiencing “vague” problems and has
unclear complaints. (Optical cause; wearer has changed his
or her mind about frame selection; family members or friends
do not like glasses; after finally seeing the glasses, the
wearer does not like them anymore; patient is experiencing
buyer’s remorse because of the high cost of the eyewear.)
These are just some of the challenges that face
dispensers every day on the front lines of ophthalmic
dispensing. Ask yourself if you and all your dispensing
staff members possess the ability to professionally and
effectively “diagnose” the cause of these problems and
effectively and efficiently correct them. If not, there are
many resources that can help in “hands-on” training.
For example, Hilco and Vigor both offer videos and DVDs
that feature in-depth tutorials with many tools and their
purpose, showing how they are to be used in a close up,
hands-on fashion. While lenses evolve, and new frame and
lens materials become available, some things never change.
Many of the techniques needed with frame adjustments today
are the same ones used a hundred years ago. System for
Ophthalmic Dispensing by Clifford W. Brooks and Irvin M.
Borish is still a great resource, as is the website I
mentioned earlier.
