Application July 25, 1944, Serial No. 546,536

2 Claims.

The invention relates to a device to aid vision particularly adapted to assist those with poor sight or those with normal sight in blinding light.

The device is in the nature of the so-called snow goggles of the Eskimo and it is an object of the invention to provide such a device adapted for use under many conditions of civilized life.

It is an object of the invention to provide a device of the character referred to having slits, preferably horizontally placed and means to largely prevent the access of light to the eyes from other directions than through the slit.

Further objects will appear when read in connection with the drawin showing illustrative embodiments of the invention and, wherein:

Figure 1 is a perspective view of a device of the invention constructed from a blank.

Fig. 2 is a plan view on a somewhat reduced scale of a blank to provide the structure shown in Figure 1.

In Figure 1 is shown a device including bows, formed from a single sheet of material 46 provided with a nose recess 41 and bows 48, 49 formed of hook shape to go behind the ears. The slits in this form of the device are formed by producing substantially vertical cuts 50, 5| and a horizontal cut 52 allowing the material thus released to be forced forwardly as far as desired to provide the width of slit needed, the upper portion serving as a shade for the slit.

As shown in this figure the nose recess is provided by forming vertical crease lines 66 and horizontal slits 61, the slits passing clear through the material. By this provision and the form of bows to be described the user may secure the device in the flat and form it to his requirements. By the crease line 66 the depth to pass over the nose may be determined and the slits 61 will permit the nose piece to conform itself to the conformation of the nose as well as providing some ventilation. The bows are shown as also formed with crease lines 68 which by the depth of the folds produced between the lines determine the length of the bows from the front to the ears. The ear portions are shown as formed with a plurality of lines of perforation 69 which the user will tear loose and fold back as shown at 10 which operation will assist in determining the effective length of the bows as well as providing 2. rolled edge to the comfort of the user. The structure shown also provides side blinders ll, 12 to prevent leakage of light from the side to annoy the user. It is contemplated that this form of the device may be die cut in large numbers and sold at beaches, ball games and the like in the flat, at a price which will make it possible to use them once and throw them away if desired. At the same time, the device will be more effective and comfortable than many of the smoked glasses now used in such locations. This form of the device will be 2 seen to provide the shading from rays from above the level of sight and also to provide adjustment for length of bow and for tension against the front of the face.

A device of the invention may be formed of a wide range of materials chosen for the desired haracter, as strength, cheapness,1ightness, translucency or sanitary qualities. Such materials as paper, card, press board, synthetic plastic, and metal among others are envisioned.

Minor changes in details of the invention may be made within the scope of the appended claims without departing from the spirit of the invention.

I claim:

1. An integral blank comprising: a central body formed with slits to free portions to be pushed outwardly to provide sight openings and with scored portions radiating from a common point to provide a nose receiving recess and also with score lines to provide blinder portion hinges; bow shaped portions extending from said blinder portions; said bow portions formed with score lines to permit deformation into length adjusting zig zag portions; said bow portions terminating in curved ear engaging hooks, their inner edges formed with perforation lines to enable the bending away of ear engaging tabs.

2'. Means to assist vision comprising: an integral structure including a frontal member formed with scores radiating from the upper cen-' tral portion thereof with the material between the scores zigzagged to form a nose receiving deformation; said frontal member also formed with slits for vision and having its opposite ends bent rearwardly at hinge scores to form blinders; bow portions forming rear extensions of said blinders through a portion of the height of each; said bow portions formed with score lines and with the material therebetween deformed out of the plane of the blinders to provide for length adjustment; the material at the free ends of said bows extending into ear engaging hooks.
