EYE'IECES - STAFF STUDY 02127
To develop a device which will permit a photo interpreter to set
his own opthalmic correction on a stereoscope eyepiece, thereby opti-
cally optimizing the microscope for his personal use and making it un-
necessary for him to wear glasses while looking through the instrument.

In Au st of 1964 the Imagery Analysis Staff received a recommenda-
tion from of the Optics Panel Scientific Advisory
Board, that an opthalmic correction device be developed and tested for
use by photo interpreters. He believes that interpreters using this
device would not only see better but-would experience considerably less
eye fatigue than if they were to wear their own glasses as they now do.
Following this recommendation CIA/IAS requested that the Technical De-
velopment Staff investigate the possibility of providing the type of
adapters suggested by
a. Current Procedures. Photo interpreters who require opthalmic
corrective devices must wear eyeglasses when using a microstereoscope.
b. Origin of Concept. This concept of individual adjustable eye-
pieces containing integral opthalmic corrective prescriptions, origi-
nally suggested byl in his capacity as a member of the Optics
Panel Scientific Advisory Board, is based on theoretical and empirical
findings that eyestrain and fatigue are materially lessened when opti-
mum optical aids are employed by individuals doing visually exacting tasks
such as those involved in the photointerpretation process.
c. Proposed Program. The proposed program will provide five sep-
arate matched sets of acuity adapters, each uniquely designed for an
individual within the photo interpretation group. The initial'five
photointerpreters were selected to provide a test sample and will rep-
resent a cross section of the visual anomalies found among a represent-

ative group of. individuals, e..g. astigmatism and myopia. These five
sets are to be tested operationally to prove the feasibility of the
concept.
d. Selection of the contractor. This contract is to be awarded
on a sole source basis because it is too small to solicit on a broad
participation basis. has been selected on the premise
that the acuity adapters are to be designed for a Q viewing instru-
ment and on the acknowledged technical competence of the firm itself.
Should the initial five sets serve to prove hypothesis,
competitive bids will be solicited to procure a larger quantity.
e. Contract Period. The acuity adapters are estimated to be de-'
liverable within two or three months from initiation of the contract.
f. Coordination. Internal.and external coordination has been
part of the project since its inception. The appropriate technical
personnel of PAG, CIA/IAS and TID have been briefed on this project.
This project has been coordinated with DDS&T/ORD and presented to the
Committee on Photographic Exploitation and representatives of Army,
Navy and Air Force.
g. Alternative. There. are two obvious alternatives to the de-
velopment of acuity adapters:
1. Use of contact lenses.
2. Continuation-of present procedures.
? The use of contact lenses poses a problem of inducing the photo
interpreter to accept them. Indications are that many photo in-
terpreters would probably not accept the use of contact lenses as
readily as acuity adapters, and they cannot legally be forced to
use them. The expense of contact lenses would probably be about
equal to acuity adapters. As explained above, the second alterna-
..tive is unacceptable.
5. RECOMMENDATIONS:
It is recommended that approval to contract with
Co. for of FY-67 funds for a three-month effort.

normally wear standard corrective eyeglasses, to remove them and still be able to
properly utilize stereoscopes. There is reason to believe that this can be done
by adding the proper corrective opthalmic prescription to the stereoscope eye-
pieces themselves. There is some medical opinion that indicates that this would
not only enable the PI to see better but would also serve to lessen overall eye
fatigue.

DEVELOPMENT OBJECTIVES
-ACUITY ADAPTERS FOR
These development objectives describe the requirements to be met
in the design and fabrication of acuity adapters (Opthalmic corrective
devices) for the = Standard lOX eyepieces as currently used with the
Zoom 70 Stereoscope.
2. CONCEPT.
1A device is needed which will permit photo interpreters, who nor-
mal* wear standard corrective eyeglasses, to remove them and still be
able to properly utilize microstere'oscopes. It appears that this can
be done by adding the proper corrective opthalmic prescription to the
stereoscope eyepieces themselves. There is some medical opinion which
indicates that this would not only enable the PI to see better but would
also serve to lessen overall eye fatigue.
3.1. Configuration. The prototype holders for the corrective optics
must clip or clamp onto the standard 10X eyepiece as
used with the zoom 70 Stereoscope, and must be easily interchangeable
from one e n is to another. The present color filter holder pro-
duced by is an example of a device which might be suitably mod-
ified for this particular application.
3.2. Lenses. Each set of two acuity adapters must have lenses
ground to the prescriptions to be provided by the sponsor. The
lenses shall be firmly and positively affixed to the holders to
avoid the possibility of accidently becoming separated from them.
The optical performance of the lenses must equal or exceed that of
a standard eye glass configurations of the same prescription.
3.3. Index Marks. Each acuity adapter must be individually marked
L (for Left) or R (for Right) as appropriate and have anotber mark
to indicate the top of the eyepiece. In addition each set of acuity
adapters must have matched serial numbers engraved upon them to per-
mit easy identification and to prevent, inadvertent separation of sets.

3.l.. Carrying Case. Each acuity adapter set must be provided
with a fitted carrying case to provide proper protection and
storage when the adapters are not in use.
3.5. General Design. The acuity adapter should be as light
and compact as possible without being fragile.
3.6. A total of 5 sets of two adapters each shall be provided
as part of this contract.
3.7. At the time of delivery of the adapters the contractor
shall also provide 10'copies of simple Users Instructions.
3.8: A carrying case shall be provided for each set of adapters.
