(Cl. 12S-25.1)
This invention is directed to a method of and
means for providing for eye treatments wherein
the conventional spherical lenses, as ordinarily
patient are in position relative tothe eyes for all
ordinary purposes, are slowly moved laterally
toward and from each other while the lenses are
employed by the patient in reading or the like,
5 are used and the treatment perfected while the
patient is using such lenses for their ordinary
and usual purpose.
It is well known in this particular art to treat
being employed by the patient for ordinary read
ing purposes.
This apparatus will be described in connection
with the accompanying drawings, in which:
the eyes of the patient for certain defects through
ment apparatus with the cover plate removed,

10 an increase or decrease of prism power and such
results have been attained by the employment of
special implements which are adjusted or changed
to suit the particular patient’s requirements
which are ordinarily costly and complicated and
15 requires the attendance of the patient at the
oiñce of the Optometrist. ,The costly and compli
cated nature of these implements materially re
stricts their use in general practice andat best
limits the number of patients who may be treated
2 O during working hours, and it is a serious en
croachment on the time »of the patient in waiting
for treatment and in making further visits for
additional treatments.
The primary object of the present invention- is
25 the provision of an apparatus of simple and corn
paratively inexpensive character in which the
treatment is provided through the use of the
spherical lenses peculiar to the patient for ordi
nary reading or'like purposes, and the apparatus
30 as a whole is designed for convenient support
upon the head of the patient, permitting the
treatments to be carried out while the patient is
using the particular lenses giving the treatment
for ordinary purposes, such as reading or the like.
It is well recognized that the ordinary spherical
lenses, when moved to the right or the left of the
optical point, increases the prism power, having
an increased stimulative effect in one direction
and an inhibitory prism effect when moved in the
40 opposite direction. The present invention is de
signed to take advantage of this well-known con
dition of spherical lenses, ordinarily employed as
eye-glasses, and to utilize, as a metho-d of treat
ment, a means for moving the lenses when in or
dinary position and function for their usual pur
pose to gain the desired prism power for treat
ment purposes.
The apparatus employed, therefore, as` an il
lustrative means of carrying out the method in
5 O volves the provision of a carrier to be removably
supported upon the head of the patient, on which
carrier ordinary spherical lenses in use by that
patient for reading purposes, or lenses similar
thereto, are mounted, with means by which the
55 lenses, which when adjusted to the head of the

The apparatus comprises a carrier including a
head band having a substantially rigid frontal
piece l to extend across the head of the patient 35
above the eyes, to the ends of which is connected
a flexible adjustable preferably elastic strap» 2 to
fit the rear portion of the head of the patient and
hold the carrier in proper position. The carrier
includes a plate 3 depending from the frontal 40
piece l and formed at appropriate points with
openings ¿l which of course, when the carrier is in
place, register with the eyes of the patient.
Extending transverse the forward face of the
plate 3 above the openings ‘i is a bar 5 formed 45
with a longitudinal guide channel 6. Rotatably
supported above the guide bar â about centrally
of the plate 3 is a gear pinion l, the shaft 8 of
which is rotatably supported in the plate and pro
vided on the rear side of the plate with a bevel - 0
pinion 9. Rotatably supported on opposite sides
of the gear pinion 'l are driving gear pinions IG
and il. These pinions i9 and Il are rotatably
supported in the plate 3 in the plane of the gear
pinion l and are in mesh with the gear pinion 1.

As the lenses 2i are ordinarily the lenses em
ployed by the particular person for reading pur
poses, it is quite apparent that when the appa
ratus is in place on the head of the patient, the
lenses are in position to serve their usual func
60 tion for reading or other purposes and that with
or his use of the lenses for ordinary purposes dur
The primary purpose of the method and ap
paratus is to build a new and comfortable reflex 35
action between the functions of sight, that is
clearness and singleness of vision. Clearness of
vision is controlled by the ciliary body including
the muscles and nerves inside the eye-ball and _
singleness of vision is controlled by the extra 40
ocular muscles outside the eyeball. There must
be a reñex action between the functions to bring
about clearness and singleness of vision at one
and the same time. This reflex action becomes
very fixed in association between the two func
tions and when lenses are placed before the eyes,
there is required an alternation in the reflex ac
tion to meet the requirements of each function.
If plus lenses are placed before the eyes, they
inhibit a given amount of stimulation that has
been flowing for clearness of vision so naturally 50
through the reflex action singleness of vision
would be less stimulated and vision would be
doubled. Immediately the brain, which is in oon
trol of all nervous energy, attempts to set up a
new reflex action between the two functions but 55
in those cases where this is not secured, that is
the alteration in the reflex action is not success
ful, outside assistance to secure the result has to
be provided.
Through the apparatus and method described, 60
the pinion 'I in motion, these lenses are moved
toward and from each other in order that the
the lenses are brought closer together and moved
prismatic effect or influence on the vision may
farther apart alternately. Thus, when plus
be varied from the normal optical point of the
lenses are used, the closer together the lenses
may be, the greater the base in prism power, giv
ing rest toV singleness of vision, but the farther 65
separated the lenses are, the greater the stimulus
to singleness of vision. When minus lenses are
used, the closer together such lenses may be, the
greater the stimulus to singleness of vision and
the farther separated the lenses may be, the
greater the rest effect.
VIn the modification shown in Figures 8 to 11,
inclusive, the instrument includes a head band
31, similar to the head band of the preferred
65 lens.
In order to provide foi` appropriate movement
of the pinion 'I, the shaft 22 is rotatably sup
ported on the rear surface of the plate 3, termi
nating at its inner end in a bevel pinion 23 in
70 driving cooperation with the bevel pinion 9 and
extending outwardly beyond one edge of the plate
3 and there provided through a universal joint 24
for driving connection with an extensible member
25, the end of which, remote from the shaft 22, is
connected through a universal joint 26 with the
form, on which is removably secured a casing 38,
preferably cylindrical. The casing is divided by
a transverse partition 39 into a rear chamber llß
and a forward chamber 4I, the latter being pref
erably of shallow depth and the former being of
a depth to appropriately receive a motor ¿i2 of a
type designed to carry out the function of the ap
paratus. The motor is conventional, forms no
part of the present invention and needs no fur
10 ther detailed description.
The motor shaft 43 extends through and is
mounted in the partition 39 and carries a gear
wheel 44 immediately in advance of the partition
39. This gear wheel (i4 cooperates with gear pin
ions 45 and 46 of identical diameter and rotat
ably supported in the partition 39 below the gear
44. Secured to the outside of the casing 38 in
vertical line with the partition 35i is a trans
versely extending plate «il which, as shown in Fig
ure 10, is of angle form.
Slidably supported on the plate @l are slides
‘i8 and 49, which slides, while mounted for slid
ing cooperation with the plate 4l, extend below
the plate and are interiorly formed with threads
25 50 which cooperate with an adjusting rod 5i hav
ing oppositely threaded portions 52 and 53 and
provided immediately beyond the ends of the
plate 4l! with knurled projections 54 through the
medium of which the rod 5i may be turned at
30 will and the slides 43 and @le caused to move to
ward or from each other in accordance with the
direction of rotation of the adjusting rod.
The respective slides d5 and 49 carry fixed
angle supports, indicated at 55 and 55, which sup
35 ports depend from the slides and are then pro
jected outwardly relative to each other in sub
stantial parallelism with the plate fl'l. The free
terminals of the supports 55 and 56 carry pins
5l on which are rotatably supported sleeves 58.
40 ’I‘he pins 5l' extend in parallelism with the axis
of the casing 48, are disposed below the casing and
project inwardly toward the head band 31.
Fixed to the inner ends of the sleeves 58 are
socket extensions 59 in which are slidably sup
45 ported bars 5B carrying appropriate lenses 6l.
The outer end of each of the sleeves 5S is rigidly
connected to one end of an angle lever £52, the
opposite end of which angle lever is connected
through a link 63 with a pin tt eccentrically
50 connected to the respective pinions :i5 and ¿56.
The eccentric connection of the respective links
63 is, of course, in diametric opposite relation
with respect to the two pinions and to provide
for adjustable throw, the pinions ¿i5 and' d6 are
55 provided with a series of radially aligned open
ings 65 for receiving the pin Sli.
The motor is energized conventionally through
flexible conductors 66 designed to be connected to
any convenient outlet box.
While the motor is
60 operating, the angle levers, through the links
allow the patient perfect freedom, within limits,
while wearing the instrument.
Through the shifting of the lenses provided, an
increased play or tolerance between the functions
of stimulation and relaxation is created, allowing
for a greater tolerance of the two functions, that
is clearness and singleness, to act in accordance
with one another while at the same time main
taining enough play between the functions to in
sure comfort and clear and single vision.
Of course, the invention contemplates, if neces
sary in a particular case, the use of an appro
priate spherical lens or the use of any combination
of spherical and cylinder lenses according to the
needs of the particular patient. Stronger lenses
may be used if necessary and the throw of the
lenses may be increased or decreased according
to the requirements of the particular patient in
maintaining the functions of clearness and
singleness of vision created during such adjust 20
The instrument as a whole is used for treat
ment while the lenses are being used by the
patient in reading or other ordinary purposes.
Thus, under the direction of the Optometrist, the ,
treatments may be taken at home during the
time the patient ordinarily employs in reading
and, therefore, no particular loss of time on the
part of the patient is occasioned for the treat
ment, such, for example, as would be the case 30
where the patient was compelled to visit the
oflice of the Optometrist by special engagement.
Furthermore, the apparatus »as a whole is so
simple and inexpensive as compared with instru
ments for similar treatments, that the Optometrist 35
may readily have a number of such instruments
and thus treat a number of patients at the same
time without discomfort to the patient and while
permitting him to employ the time of treatment
in reading, for example.
It is, of course, to be understood that the
present apparatus 'is designed for the handling
of spherical lenses employed for reading and like
purposes and thus to be clearly and carefully dis
tinguished from testing lenses which are only em 45
ployed for the purpose of testing the eyes to de
termine what spherical lenses will be later con
structed for use. Therefore, in the following
claims, the term “ordinary” is intended to mean
those lenses which would ordinarily be employed 50
in eyeglass frames for the use of the particular
person in reading, and to this extent the inclusion
of the term “ordinary” in the claims is intended
to limit the type of lenses with which the con
struction and operation dei-ined in the claims is 55
particularly concerned.
What is claimed to be new is:

In the form of the invention shown in Fig
ures 8 to l1, inclusive, as well as in the preferred
form, the apparatus as a whole is designed to be

nary reading purposes during treatment. Of
75 course, the conductor 66 is of such a length to
the lenses on the head of the user in a position
the lenses relative to each other to insure maxi
mum prismatic effect for reading purposes, and
increase the prismatic effect of the lenses while at
all times maintaining the lenses in that position
relative to the eyes of the user as will permit the 70

such as to avoid interference with the reading
function of the lenses during such movement.
