Abstract

The device for training the ciliary muscle comprises a drive element with which the screen (17) can be moved away (p +) and back (p -) from the viewer's eye. The movements can be uniform or non-uniform with regard to distance and the speed of movement can also be set.

Description

Description of the invention is a device for training the ciliary muscle when working on the screen or reading a book according to the preamble of claim 1.

By remaining in the same viewing distance, be it at work, reading a printed book or with an e-book or in the evening while watching TV, the ciliary muscle loses its contractility. In all these activities, the distances between the eye and the screen viewed by it only vary insignificantly over a long period of time. This object, which is always at the same distance from the eye, means that the ciliary muscle (musculus ciliaris) is gradually no longer able to contract accordingly, so that it gradually loses its contractility, which ultimately leads, among other things, to the generally known presbyopia. A visual aid in the form of glasses or lenses is required for working over short distances.

An object of the present invention is now to provide a device with which the ciliary muscle is forced to contract frequently during activities on the screen, reading a book or watching television, thereby promoting the ability to contract.

This object is achieved by a device according to the features of claim 1. Advantageous embodiments of the devices are described in the dependent claims 2 to 8.

By frequently changing the distance of the images captured by the eyes by moving the screen perpendicular to the screen surface, it is possible to activate the ciliary muscle, ie to increase its contractility. These changes in distance can advantageously take place aperiodically and at different speeds. In other words: by constantly varying the position of the screen by an amount p “to p ⁺ and the speed of the changes in which the distances are changed, the ciliary muscle is forced to contract accordingly frequently. Consequently, he will do this accordingly and be able to adapt the eye accordingly to the new circumstances.

1 of an eyeball 1, reference number 3 denotes the ciliary body (corpus ciliare). The ciliary body 3 encompasses the lens 5 of the eye. The vitreous 7 is surrounded by the retina 9, the choroid 11, and the dermis 13. The optic nerve 15 is indicated on the rear wall of the eyeball. The accommodation is brought about by the contraction of the ciliary muscle (musculus ciliaris) in the ciliary body 3. The inner circumference of the radiation body is narrowed, as a result of which the lens 5's own elasticity rounds it, thereby reducing its radius of curvature, which leads to close-up adjustment. When the ciliary muscle slackens, the lens 5 is pulled back into a flattened shape (remote setting) against its inherent elasticity.

In order to prevent or undo this slackening of the ciliary muscle, according to the invention the screen 17 of a laptop, as shown in FIG. 2, is connected to a transport carrier 19. The transport carrier 19, in the example shown there are 3 guide rods 21, causes the viewer to move in the direction p ⁺ and p by moving the guide rods 21 into and out of the laptop base body 23 or by moving the screen 17 along the guide rods 21. is moved or moved and thereby the distance between the eye and the image on the screen 17 changes. The guide rods 21 or a carriage seated thereon can be driven via a belt drive, a friction wheel, a gearwheel which meshes with the guide rods 21, a spindle drive or can be carried out with a pneumatically or hydraulically operating piston / cylinder arrangement. The drive means, not shown, from the technology of linear drives are accommodated in the base body of the laptop 23 or used in a separate drive element at the free end of the guide rods 21.

In the second embodiment of the device according to FIG. 3, the screen 17 is attached to a base 25 in which a guide means acting essentially perpendicular to the screen surface, such as a rail (rail not shown), is let in, on which a roller is guided on a screen support 26. With one too

CH 710 751 B1 drive means, not shown, such as a rack, a toothed belt, a spindle or a linear drive, the screen 17 can be moved on the base 25 in the direction of the arrows p ⁺ and p ".

In the third embodiment of the device according to FIG. 4, a guide profile 27, which is attached to the screen 17 at a substantially right angle on the back, is displaceably mounted in a fixed columnar guide carrier 29 on the screen 17. The drive in the direction p ⁺ and p “of the guide profile 27 can be arranged within the guide profile 27 or within the carrier 29. Again, the same drive elements, such as belts, spindles, friction wheels etc., can be used.

In the fourth embodiment of the device according to FIG. 5, the screen 17 of a television set or a computer is attached to two Nuremberg scissors 31, which in turn can move the screen 17 in the direction p ⁺ or p “by a drive member. The drive elements for the Nuremberg scissors 31 are not shown, but are known from other application examples, such as lifting platforms and the like, and are designed, for example, as linear drives.

In the fifth exemplary embodiment according to FIG. 6, a screen of an e-book 33 is fastened to a guide profile 27 which can be set up essentially vertically and can be displaced in the direction p ⁺ and p ". With adjustable and retractable supports 35, the guide profile 27 can be set up next to a bed or sofa, for example, and the e-book 33 or its screen 17 can be moved in the vertical direction, thus changing the distance from the viewer.

In the two representations a) and b) of the device and in the sixth embodiment in FIG. 7, the e-book 33 or its screen is in turn fastened movably on a guide profile 27. It can be moved along the guide profile 27 with the drive elements described in other examples.

The drive members, such as electric motors, in the guide profiles 27 or, as shown in Fig. 3, in the base 25 or, as shown in Fig. 2, in the laptop 23 are controlled electronically. Different motion sequences can be programmed in the electronics. In the simplest version, the screen 17 is guided back and forth in the direction p ⁺ and p “over a predetermined range, for example with a sinusoidal course. This movement can take place at a constant speed or the speed can be designed to be variable over the route, ie the screen moves faster or slower over a certain distance. Furthermore, the speed between the reversal points can be temporarily reduced to «0» or the direction of travel between the two end points can be reversed briefly one or more times. Either with or without a break. The distance between the reversal points can also be lengthened or shortened. Intermediate stops can be made at the ends of the movements and / or between the end points.

By this continuous or discontinuous back and forth of the screen 17, the ciliary muscle is constantly stimulated and consequently trained to focus on the subject.

The controller can e.g. also take place via the devices used such as e-book or PC
