EYE-EXERCISTNG DEVICE.

Application filed August 18, 1922. Serial No. 532,650.

To all whom it may concern:

Be it known that I, NELsoN YoUNo HULL, a citizen of the United States, and a resident of Plainfield, intthe county of Union and State of New Jersey, have invented certain new and useful Improvements in Eye-Exercising Devices, of which the following is a specification.

The purpose of the invention is to provide an efficient device with the use of which a person may subject the ocular muscles of the eyes (four recti and two obliques) to proper exercising motions or-"exerciseswhereby to maintain them in condition to perform their proper functions and thus avoid defects in vision due to one or more of the muscles failing to properly or fully coact with the other muscles, and also, whereby the ocular muscles may be stren thened and restored to normal condition and properly perform their functions should one or more of them fail to respond to or coact with the other muscles.

The more especial object of the invention is to provide a device with the use of WhlCh the ocular muscles may be so exercised as to. efi'ectually correct, in the eyes, the conditions known as myopia and myopic astigmia, and, also, hypermetropia and hypermetroplc astigmia.

A further object of the invention is to provide a very simple, light, inexpensive and eflicient device capable of use with slight instruction, adapted for effecting the exercise of the ocular muscles in accordance with the main purpose ofmy invention.

The device of my invention, in one form thereof, comprises an angularly bent plain' wire rod having on its outer or free end a fixation object, as a small Wooden ball or the like, and atits other-end portion-having a plain straight section to be held in one hand and an ofiset section or crank member to be held in the other hand and from which the'tree end of the rod is *given its movements to carry the fixation object back and forth laterally on ahorizontal plane, as often as necessary, on the 180 meridian, or up and down perpendicularly on the 90 meridian, or back and forth angularly on any angle between the 180 meridian and O meridian, or to the right or left on the line of a complete circle, as. the nature of the correction sought may require. The aforesaid plain straight section of the device has on it a loose sleeve or handle to be normally held stationary and in the left hand and Within which said section may have rotary motion, this section represent ing the axis of motion of the device, and the said offset or crank section has on it a loose sleeve or handle to be grasped by the right hand operating the device, said crank section being loose in its handle so that the operator may actuate the device while maintaining a fixed hold on said handle. Of course either hand may be used for holding the device at said straight section while the right or left, on a complete circle;

Fig. ,3 is a front elevation illustrating the device or my invention in use and as being actuated to move the fixation object up and down perpendicularly on the 90 meridian;

Fig. dis a side elevation, partly in section, of the device, and v Fig. is an edge view of the same.

lln the drawings 10 designates the device as a whole, said device comprising an'outstanding body portion 11, a free end portion or arm 12 bent angularly in one direction from one end of said body portion and carrying a fixation object 13 on its outer end, a straight axial section 14: bent angularlyin the opposite direction from the other end of said body portion and an ofiset or'right angular cranksection 15 extending from the said axial section, said body portion 11, arm 12, axial section 14 and crank 15 being formed from a single plain rod of metal, as stifi' wire, and hence being in one integral piece. The fixation object 13 may be of any suitable character and I prefer to make the same of wood and of somewhat spheribal form and l provide therein a socket to tightly receive the outer extremity of the arm 12. On the axial section It and crank arm 15 ll preferably provide loose fitting wooden handles 16, 17-, respectively, for con of the operator an the section 14 and crank -arm 15 being adapted to rotate or turn freely within said handles. The upper portion of the body 11 is preferably bent inwardly over the section 14 and crank arm 15 at the point 18 for several reasons, one being for convenience in holding and operating the device with the fixation object efficiently positioned with relation to the eyes, as will be-understood on reference to Figs. 1 and 3, and another reason being to permit the device to be enclosed in a flat stifi' oblong paper envelope or container having a width slightly greater than the length of arm 12 or the combined length of the sections 14, 15.

In the normal use of the device the handle 16 will be held stationary in one-hand and the handle 17 will be grasped in the other hand and by which the crank arm 15 will be swung back and forth on the arc of a circle or on the line of a complete circle, as may berequired, with the result .that the axial section'14 will turn correspondingly in the stationary handle 16 and communicate corresponding motion to the body 11, arm 12 and fixation object 13, the movement of the crank arm 15 being exactly reproduced, on a longer radius, inthe arm 12 and object 13 and under the steady control of the operator.

.A less convenient manner of employing the device would be to hold the handle 17 stationary in one hand and with the other hand on the handle 16 efiect the rotary or rocking motion of the body 11 with its arm 12, the crank arm 15 then being the axis of motion, andthe section 14 a crank member. The device may also be operated with the bare hands on the axle and crank sections, said sections then being allowed to slip, while turning, in the hands. The axle and crank sections of the device should, however, in the interests of convenience and completerligssl pe equipped with loose fitting handles The nature of the correction desired will determine the movements to be imparted to the fixation object 13, and in all cases the actuating end of the device will be held in near relation to the body of the operator so that the handles 16, 17 may be conveniently asped in the hands and the arms steadied y being in a natural position against the body. or the correction of myopia and myopic astigmia, the ocular muscles should be subjected to several exercises, and in Fig. 1 I illustrate one of said exercises consistmg 1n operating the device to swing the fixatlon object back and forth horizontally and.

about on a level with the eyes on the 180 meridian, the eyes intently following said object, and the muscles then exercised being the external and internal recti muscles and the exercise being chiefly for the correction of myopia and myopic astigmia. For the correction of myopia and myopic astigmia the superior and inferior recti muscles should also be brought into condition to function normally, and I accomplish this result by the exercise illustrated in Fig. 3, wherein it may be seen that I operate the device to move the fixation object up and down perpendicularly at the front of the eyes on the 90 meridian, the eyes closely following said object and being alternately elevated and depressed. A further aid to the correction of myopia and myopic astigmia, is to exercise the superior and inferior recti muscles by. causing the fixation object to move 'on slanting or angular lines, at the right and left, between the 180 meridian and 0 meridian, theeyes closely following said object.

For the correction of hypermetropia and hypermetropic astigmia, it is necessary that the inferior and superior oblique muscles should be strengthened and brought to nor mal condition, and this result may be accomplished by the proper exercise of said muscles with the use of my device operated as indicated in Fig. 2, the device then being actuated to carry the fixationobject on the line of a comp ete circle, both right and left, with the eyes intently following said object.

The exercises described above properly energize the ocular muscles and result in other corrections than those I have specially noted, as, for instance, a defect in the conjugate mobility of the eyes may be corrected by energizing the ocular muscles with the use of my device.

If the eyes should apparently be normal, they may be improved and kept in ood normal condition by the exercise of t e ocular muscles with the use of my device, such exercise bringing all the ocular muscles into normal action and keeping them in condition to function properly, and if defects should exist and are subject to correction by causing the muscles to properly function, such defects may be remedied with the use of my device.

It will be understood that 'in the use of my device, the movement of the, fixation object is under the control of the person handling the device, and said object should be moved somewhat slowly, especially at the beginning of the treatment. so that the eyes may closely follow said object without placing sudden strains on the ocular muscles or other parts of the eye.

The form of the device of my invention is subject to modification and my invention is not therefore confined to the form of that device shown; said form is however one that I have found to be the most efiicient and convenient for all practical purposes;
