Description

The present invention relates to a device for at least partial elimination of farsightedness, myopia, strabismus, astigmatism and / or other eye musculature weakness caused or sustaining or aggravated diseases of the human eye, according to the respective preamble of claim 1. Furthermore, the present invention relates to the use of a corresponding device according to the preamble of claim 10.

Eye training is based on the assumption that physical or emotional overexertion leads to blurred vision. Constant screen work puts a lot of strain on the eyes because some muscles are overused. The aim of the exercises is to reduce the stress of seeing. The techniques also aim to relax the neck and shoulders.

With targeted muscle exercises, the eye movements should become more dynamic and controlled. The aim is to consciously influence the position of the eyes and the width of the lens when seeing. For example in the process of accommodation. Doctors speak of accommodation when the eye focuses on an object. Well trained eyes can see objects more clearly after accepting many eye trainers by changing their position and angle.

Eye trainers also try to compensate for changes in the eyeball. This happens, for example, to people who stare at a screen for more than three hours a day. The eyeball elongates. This can lead to myopia.

Studies have shown that education and behavior have an even greater influence on myopia than genetic factors. Whether and to what extent sitting too close to the screen alone promotes the growth of the eyeball and thus promotes myopia is unclear.

In order to improve eyesight, patients need to do the exercises regularly and with concentration over a long period of time. This would make seeing easier and clearer. The promised effect is not always measurable in diopters, but many participants and eye trainers can confirm an adjustment or reduction of the blurring of vision.

Eye training can even be proven to correct existing visual damage. The exercises can also prevent a deterioration in eyesight, stimulate the visual muscles and relieve tension. For example, presbyopia can be postponed. The goal is always more relaxed vision. Basically, vision training always makes sense if the visual impairment is caused by stress or frequent staring at text or a screen.

According to the Verein für Gesundessehen e.V., the best results in eye training can be achieved with presbyopia, farsightedness and nearsightedness. In addition, eye exercises should also help with screen damage, strabismus and astigmatism. Which exercises help in each individual case must be clarified on an individual basis.

Devices for eye training of this type known in the prior art are not only cumbersome to handle, but also cost-intensive, and devices already known do not satisfy the need to be particularly individually adaptable to, for example, a head of the human body. Furthermore, previously known devices are not easily able to continue to pursue an eye training principle, which, among other things, consists in gradually moving the alignment and / or target point as part of a training plan in order to relax the eye muscles and / or even to exercise.

Based on this, it is therefore an object of the present invention to provide a device for at least partial elimination of farsightedness, myopia, strabismus, astigmatism and / or other weaknesses of the eye muscles caused or maintained or aggravated diseases of the human eye, which can be done in a particularly simple and inexpensive way and way enables to solve the above-mentioned problem.

In particular, the device described here comprises at least one alignment system comprising at least one alignment and / or target point, wherein the alignment system is arranged stationary and / or movable relative to the human eye, so that the alignment and / or target point is passed through the human eye at time intervals can be focused again and again.

In particular, the above-mentioned target alignment and / or target point can move along the optical axis or an axis that is otherwise freely selected relative to the optical axis. By wandering the alignment and / or target point, training of the eye muscles, in particular reinforcement and / or relaxation of individual or all eye muscles, can be generated.

Furthermore, the device described here comprises at least one holding system for positioning the alignment system relative to the human eye.

The holding system can be a holder or some other haptically perceptible and structural entity that is in particular mechanically connected to the alignment system and holds the alignment system during the learning process, i.e. while the alignment and / or target point is wandering. It can be held on the human head or on the floor or some other basic posture positioned away from the human body.

A concept that is essential to the invention of the present system is, inter alia, that the holding system and / or the alignment system has a displacement path along an optical axis of the eye for moving the alignment and / or target point along the optical axis.

According to at least one embodiment, the device for at least partial elimination of farsightedness, myopia, strabismus, astigmatism and / or other diseases of the human eye caused or sustaining or exacerbated by weaknesses in the eye muscles comprises at least one alignment system, comprising at least one alignment and / or target point, wherein the alignment system is arranged stationary and / or movable relative to the human eye, so that the alignment and / or target point can be focused again and again at time intervals by the human eye.

The device further comprises at least one holding system for positioning the alignment system relative to the human eye, the holding system and / or the alignment system having a displacement path along an optical axis of the eye for moving the alignment and / or target point along the optical axis.

According to at least one embodiment, the alignment system is formed in the form of glasses frames or comprises one, the glasses frames of at least one connecting element being mechanically connected to one another, in particular wherein a field of view of the glasses frames relative to the optical axis of the eye from the side by means of at least one restriction means at least partially is restricted, so that an edge of the restriction means that can be recognized by the eye can be focused within the still remaining field of view of the eye within the edge of the spectacle frame.

According to at least one embodiment, the restricting means is formed with a covering element which is inserted into the spectacle frames in a detachable or non-detachable manner.

According to at least one embodiment, the covering element is formed with paper, cardboard and / or plastic.

According to at least one embodiment, the alignment system is in the form of at least one orientation plate or an orientation marker arranged on the holding system away from the human eye and at a distance from the user, in particular, with a main extension plane of the orientation plate oriented perpendicular, parallel or at an angle relative to the optical axis is.

According to at least one embodiment, the alignment system is designed in the form of virtual glasses, which are haptically arranged on the holding system, so that these virtual glasses can be placed on a person's head via the holding system, the orientation and / or target point on a display of the virtual glasses can be displayed within the field of view of the human eye.

According to at least one embodiment, the device is characterized in that, by means of at least one computer system of the virtual glasses, the alignment and / or target point can be predefined in terms of time and / or location.

According to at least one embodiment, the alignment system is at least partially formed with a carbon fiber reinforced plastic, also carbon fiber reinforced plastic (CFRP) and / or a glass fiber reinforced plastic (GFRP).

According to at least one embodiment, the alignment and / or target point can be adjusted along the optical axis by means of an internet-based control.

Furthermore, the present invention relates to a use of the corresponding above-mentioned device, with all advantages of an advantageous embodiment, as described in relation to the device, being disclosed for the use claim described here, in particular also the method claim described here, and vice versa.

According to at least one embodiment, the holding system and / or the alignment system can be controlled and / or enabled by means of the 2D and / or 3D gesture and / or face recognition system (hereinafter also referred to as gesture recognition system). For this purpose, the gesture recognition system can be installed in the holding system and / or in the alignment system. In at least one embodiment, to recognize the gestures and / or the face, the gesture and / or face recognition system comprises at least one detection means, for example a camera and / or a sensor, such as an infrared sensor. Once a user has been stored in the system, it is conceivable that, after activation, the user-specific training data (pattern sequence, brightness, color, etc.) will be loaded and played.

According to at least one embodiment, the 2D and / or 3D gesture recognition system first carries out a pre-user gesture recognition and / or a pre-control recognition, only after a CPU compares the corresponding gesture with control gestures stored in the database of the CPU and the corresponding gesture of a group of control gestures assigned, the sensor has made a fine selection of a gesture from the group of preselected gestures, so that the gesture then obtained through the fine selection essentially corresponds to that made by the user, so that the object of use can be controlled via this gesture that is then selected.

The individual gestures can be combined to form one or more data clusters and / or data blocks. For this purpose, it is conceivable that each individual or a group of gestures are recorded by the gesture recognition system from the image data recorded in this way are classified into one or more gesture classes, that is, grouped, the comparison of this data with the gesture data stored in the database is a classification comparison of data classes of the Comprises gesture data with data classes of the database gesture data, wherein a classification of the respective gesture on the basis of movement vectors of a body part, for example the eye, in particular the eyeball, of the user is carried out in such a way that a movement profile is first created from the temporal movement of the body part, whereby the Movement profile of the body part includes movement vectors of the same, and further wherein the CPU combines the individual gestures, which were collected over a predetermined period of time, into so-called data blocks or data clusters, which are then classified in terms of their shape and / or extent be ized.

According to at least one embodiment, at least one data class of the gesture data corresponds to at least one data type of a gesture stored in the CPU.

In the context of the invention, a group of data objects with similar properties is referred to as a data cluster. The set of clusters found in a data set is called clustering, a method for calculating such a grouping as cluster analysis. Data objects that do not belong to a cluster are called outliers, or noise.

The core idea of a cluster is that data objects in the same cluster have “similar” properties and thereby differ from objects that are not in the same cluster.

In the case of only one gesture, that is to say when a single gesture is sufficient to (control) a usage object, this can also be assigned to one, preferably exactly one, blop or cluster.

This can be advantageous because incorrect analyzes due to disruptive external influences such as sudden exposure from the sun, for example, or internally by regulating the optical components can be largely ruled out. Tracking the objects (that is, tracking a part of the body such as the user's hand) also allows a statement to be made about the direction of movement and thus also about the length of time in a specific virtual segment area in front of the camera.

It should be noted that instead of or in addition to the gesture control and gesture classification described above, the same can also be done via the sensor of the device described above.

According to at least one embodiment, the alignment system comprises at least one display for displaying various training patterns, the screen having a width, length and / or diagonal cross-section in a direction perpendicular to the optical axis, which is at least 2m and at most 4m, preferably at least 2.5m and at most 3 , 5m, for example 3m. The distance between the display and the eye can be at least 2 m and at most 5 m, preferably at least 2.5 m and at most 4 m, for example 3.6 m.

In at least one embodiment, a ratio of 3 m (distance) to 3.60 m (width) has proven to be advantageous.

According to at least one embodiment, the display is formed with at least two partial displays, the two partial displays being plugged together virtually or haptically and coordinated with one another. This “coordination” can result in the partial displays, after being put together, producing respective partial areas of an overall image, for example an overall pattern.

According to at least one embodiment, the alignment system presented here or the virtual glasses presented here comprise at least one display which can show at least one image pattern, for example a training pattern.

This can be achieved in that the virtual glasses comprise at least one display, with the virtual glasses being able to be stretched over the head of the user, for example. It is conceivable that a screen centering deviating from the optical axis, i. H. thus shifted in parallel can be shifted in a direction perpendicular to the optical axis. This can be based on the fact that a multifacetedness present relative to the optical axis is formed asymmetrically relative to the optical axis.

It is also conceivable that a screen centering moves back and forth in the direction perpendicular to the optical axis from left to right or from right to left during a period of use.

It is therefore also conceivable that an astigmatism of the eye, that is to say a varying thickness of the cornea, can be compensated for.

In the 1 a first exemplary embodiment of a device 1000 described here is shown in a schematic perspective view, it again being recognizable that this device 1000 is an alignment system 1 has, which is in the form of glasses frames 10 is formed so that an alignment and / or target point 11 is adjustable and / or changeable relative to the human eye.

This can in particular be achieved in that along an optical axis A10 which is defined by the eye, but preferably which is perpendicular to a glasses frame plane generated by the glasses frames, can be displaced.

The device 1000 comprises a holding system 2 for positioning the alignment system 1 , wherein in the present embodiment the holding system 2 by eyeglass temples and a connecting element 12th is formed.

Can be seen from the 1 that a restraining agent 3 with a cover element 31 is formed, in the present case the alignment system 1 , ie the glasses frames, each have a, preferably a single, covering element 31 each have.

In the 2 is a schematic perspective view of virtual glasses 1 shown, which can be placed on a human head of a person.

In the 3 Corresponding training paths are shown (in the direction of the arrow) which can be trained within an at least partially covered field of view.

In the 4A is a relative to the optical axis A10 back and forth hike shown (arrow direction left and right), which allows an asymmetrical training of the eye muscles. A screen centering to the left and right, viewed from the optical axis, assumes a maximum angle α in each case. The angle α can be between at least +30 degrees and at most -30 degrees relative to the optical axis A10 wander back and forth. For example, the angle α can be set at an angle of at least 20 and at most 80 degrees relative to the optical axis.

In the 4B a thickness D of the cornea is described relative to the angle α. As can be seen, based on the curve 410 decreases relative to the optical axis A10 the thickness of the cornea its minimum at the intersection with the optical axis A10 and assumes its maximum toward the outer sides, ie toward the sides which, for example, assume the maximum absolute values of the angle α.

This different thickness relative to the angular dimension in relation to the optical axis A10 can be compensated by a correspondingly shifted centering by the angle α or by an angle that is smaller within the absolute limits.

It is conceivable that a displacement of the frame centering of the screen frame by the angle α corresponds to the angular degree α, at which left and right viewed from the optical axis A10 , the cornea assumes a maximum thickness.

In other words, the eye is trained in those places which, measured in terms of the corneal thickness, have the largest point, but the reverse is also conceivable, so that precisely the angle of the displacement angle α is one at which the cornea assumes the smallest thickness.

According to at least one embodiment, the display can be aligned on a tripod. The tripod can therefore have various adjustment methods, such as screws, eyelets or measuring elements, which make it possible to enable manual, semi-manual or fully automatic alignment. This can be coupled with the face recognition described above.
