    Electronic device for visual therapy Technical sector
    The invention falls within the technical field of Optometry, as a visual therapy device. State of the art
    Currently, various electronic devices are used to perform visual therapy and others that are simpler in their mechanism, with or without an optical system, to simulate different working distances and evaluate binocular or accommodative anomalies and their treatment. Vision therapy consists of changing incorrect parameters of ocular motility, foveolar fixation, monocular and binocular vergence of the eyes, stimulation and relaxation of accommodation, peripheral or central vision, flat and raised fusion and the sum of all of them. In short, visual therapy seeks to improve vision as a set of coordinated elements to allow the best performance and maximum visual acuity. There are many materials in paper, cardboard, wood, metals and plastic, very simple, with which this task is carried out. Other visual problems such as functional amblyopia, accommodative strabismus, aniseiconia, diplopia, suppression are also resolved, either partially
    or totally, using these additional devices and materials. Although, in many cases, a simple printed paper with the necessary elements is enough to solve a therapy, other devices have been developed. For example, WO2012 / 142104A1 describes an apparatus having optical elements with different optical characteristics; By rotating the device, the user has to focus on the different elements that appear, which improves their ability to focus and verify. In US2008 / 0191965A1, an apparatus for performing eye exercises using a set of glasses containing a screen is described so that the user can observe a set of LEDs which, when illuminated sequentially, cause the user to exercise the muscles of the eye. the eyes. Another example can be US4756305A where a device is described to treat one or more disorders in a patient (amblyopia, strabismus, accommodation); The device displays two images that are virtually superimposable in a single image and optically drives one of the images to the right and the other to the left. On the other hand, current research is oriented towards the development of applications for mobile devices such as the multiple ones developed for Smartphones and computers. An example of this is the invention published in US2011 / 0013138A1.
    Despite the variety of tools available, we have not found devices that work with simultaneous stimuli in two different and variable planes and that, moreover, can be manufactured in such a way that they are transportable. Description of the invention
    Electronic device for visual therapy. It is based on two light stimuli and the user's reflection in a mirrored sheet so that the light stimuli and the user's reflection are in two differentiated and variable planes. This device is specially designed to improve the coordination of both eyes and their vergences, accommodation and flat fusion.
    The device of the invention includes several elements: -A first hollow element (1) whose shape corresponds to that of a polyhedral or round geometric body, with an opening (1 A) made in one of its faces, or in a portion of one of the curved surfaces, of a width
    or minimum diameter of 12 centimeters. This first hollow element (1) can preferably have the shape of a parallelepiped or a cylinder and, in particular, with the base longer than the height.
    - Along the opening (1 A) made in one of the faces of the polyhedral geometric body, or in a portion of one of the curved surfaces of the round geometric body, of the first hollow element (1), the device has a rim (1 B). Said flange can have a width of between 5 and 10 cm. -A second hollow element (2), whose shape corresponds to that of a polyhedral or round geometric body, has the appropriate size to be inserted tightly through the edge (1B) of the opening (1A) made in one of the faces, or in a portion of one of the curved surfaces, of the first hollow element (1). This second hollow element (2) has a first opening (2A) on the face, or portion of the curved surface, which coincides with the opening (1 A) of the first hollow element (1) AND another opening on the opposite side (2B ) to the first opening of this second hollow element (2) in which a mirrored sheet (3) in the shape of a spherical cap is inserted. The spherical cap can have a variable diameter that must be at least 60 mm. The second hollow element (2) can preferably have the shape of a parallelepiped, a cube or a cylinder. -Inside the first hollow element (1) two light sources (8) are placed. To move them from right to left with respect to the user's eyes, bringing them closer and apart from each other, or moving both light sources (8) at the same time, each of them is inserted into a holding shaft (10) that, in turn, it can be moved horizontally, from left to right with respect to the mirrored sheet, by means of a motor (7). -The set of the two clamping shafts (10) with their corresponding motors
    (7) is coupled to a shaft (9) that moves by the action of a lateral motor
    (6). The movement of this axis is horizontal, from left to right with respect to the mirrored sheet (3), that is, from left to right with respect to the user. -So that the second hollow element (2) can slide in the paraxial plane along the edge (1B) of the opening (1A) of the first hollow element (1), rails (4) are placed on the surface of the second hollow element (2) that contacts the flange (1 B). At least two rails are placed (4). On the other hand, one or more stop pieces (5) are included to prevent, when sliding, the second hollow element (2) from contacting the set of two clamping shafts (10) where the light sources (8 ), with their corresponding motors (7). -A power and control system to electronically regulate the movement of the axes (9) and (10), as well as the switching on and off of the motors (6) and (7) and of the light sources (8). The power and control system obtains energy through an electricity input or with batteries and includes an electronic control unit (12) and a control knob (14).
    As light sources, preferably, LED lights are used and, especially, tricolor LEDs, which allow not only changes in the intensity of the light, but also in its color.
    The device of the invention can be manufactured with light materials in cases where it is desired to obtain a device that is easy to transport. In particular, light materials can be used for the first hollow element (1), the second hollow element (2) and the flange (1B). By light materials, in this invention, plastic materials are understood, such as: polyvinyl chloride (PVC), polypropylene, polyethylene, polystyrene, etc., and metals and / or alloys with a density equal to or less than 4.5 g / cm3, such as titanium
    or aluminum.
    By means of the 3 motors (6 and 7) contained in the device of the invention, the light sources (8) can be moved by modifying the distance between them and moving them horizontally to the right and left with respect to the mirrored sheet (3), forcing the patient to chase them with his eyes, in the positions desired by the examiner. The lateral motor (6) allows the lateral displacement of the light sources (8) by moving them together with their motors (7) en bloc to the right and left with respect to the patient's eyes. The motors (7) of each light source (8) allow that, individually, a light source (8) can be moved simply to bring it closer to the first or away from it. These movements, in combination with the image of the patient himself in the mirrored sheet (3) of the second hollow element (2), allow us variations in the vergences or movement of approach and distance between eyes and the flat fusion or the ability to maintain a Simple image despite zooming in or zooming out close to the outer limits, reinforcing the desired visual parameters for better vision. By using this electronic device, visual coordination, vergences, accommodation, and flat fusion can be improved.
    Therefore, another aspect of the invention refers to a vision improvement method that includes the use of the device described in this specification, by means of the horizontal movement of the light sources (8), from right to left with with respect to the mirrored sheet (3), and the movement of the second hollow element (2) in the paraxial plane.
    The device is controlled with a command (14) that can be wireless or be connected by a cable (13) to the electronic control unit that allows the movements of the light sources (8), the intensity and color changes of the the three-color LEOs when they are incorporated into the device, and the activity of the motors (6 and 7) through the corresponding wiring (11).

    The accompanying drawings, which are not intended to limit the scope of the invention, show the main characteristics of the invention:
    Figure 1. Scheme of the device of the invention.
    Figure 2. Device of the invention with the two hollow elements (1 and 2) separated.
    Figure 3. Three consecutive figures of the front of the device of the invention with reflections of the user's face (15) that are seen simultaneously with the LEOs used as light sources (8) that move in different positions approaching each other, moving away from each other or simultaneously moving to the right or left relative to the user. 5 Mode of carrying out the invention
    The present invention is further illustrated by the following example, which is not intended to be limiting of its scope.
    The first hollow element (1) with a parallelepiped shape was built, with a depth of 150 mm, width of 300 mm and height of 300 mm, made of PVC. A square-shaped opening (1A) of 12 cm on a side was made, around which a rim (1 B) of 12.5 cm on a side, 8 cm deep and 5 mm thick was inserted. The second hollow element (2) was designed with
    15 a size of 12x12 cm (height x base) and 10 cm deep, to fit it in the opening (1A) of the first hollow element (1). The mirrored sheet (3) on the front of the second hollow element (2) was manufactured with a radius of 60 mm in plastic material. This mirrored sheet was mounted in a circle drilled in one of the faces of the second hollow element (2). For displacement
    20 sagittal of the second hollow element (2), two rails (4) of approximately 0.3 cm thick were included on the surface of the same that contacts the edge (1B) of the opening (1A) of the first hollow element (1 ), in which grooves of depth equivalent to that of the rails were made to guide their sliding, thus achieving an additional movement
    25 from front to back with respect to the tricolor LEOs that, in this example, were used as light sources (8), and that allows a differentiated targeting according to the observed stimulus. Two stop pieces (5) were embedded in the sides of the second hollow element (2) to prevent the second hollow element from
    (2) rubbing with the clamping shafts (10) and with the LEOs. In the first element
    In the gap (1), a lateral motor (6) was arranged to allow the lateral displacement of the set of LEOs and the individualized LEO motors (7). These LEO motors (7) move each LEO separately to join or separate them. Any of these motors (6 and 7) allows the shafts to rotate
    clamping (9 and 10) to perform the movements described here. All motors carry the wiring (11) necessary to provide them with energy through the electronic control unit (12). Finally, this unit was connected, on the one hand, to the electricity or battery input and, on the other, in this example by wiring (13), to the control knob (14) where on and off buttons are included, of independent movements of the LEOs and of the set formed by the two clamping shafts (10) with their corresponding motors (7), as well as the lateral motor (6) with which the shaft (9) moves; in addition, by means of the control knob (14) the changes are regulated
    10 of the color and intensity of the LEOs themselves.
