VISION TRAINING GLASSES SET

Description

technical field

[0001] The present invention relates to the field of training devices for the recovery of optimal vision.

[0002] The invention relates more particularly to a set of vision rehabilitation glasses in which each pair of glasses covers a different part of the field of vision for dynamic training and holistic recovery of optimal vision. The invention also relates to a method of comprehensive vision training based on the use of this set of rehabilitation glasses. State of the art

[0003] The decline in vision is due both to the aging of the eyes, but also to the progressive loss of the brain's ability to instantly and continuously process information from the eyes to create images.

[0004] Correcting age-related eye defects falls within the medical domain, while exercising the visual cortex falls within the domain of learning and training.

[0005] To train the visual cortex to better process the visual information it receives and thus improve vision, it is known to wear pinhole glasses, also known as pinhole glasses or pinhole spectacles. These are opaque glasses with multiple tiny holes that allow a beam of light to pass through to the eye, eliminating light scattering and reducing the blurring of the retina. These tiny holes are about 1 millimeter in diameter, usually 1 to 1.2 millimeters, and their edges are generally spaced 3 to 4 millimeters apart. These glasses are usually worn gradually, for two to five minutes a day, to avoid eye strain.These pinhole glasses aim to strengthen and restore flexibility to the extraocular muscles, which are increasingly less used through their full range of motion, thus considerably improving the wearer's vision. Reactivating the muscles surrounding the eyes also stimulates blood flow throughout the entire orbit.

[0006] However, these glasses and their use only allow for the partial and static re-toning of the eye muscles and visual cortex. The inventor has discovered that it is possible to significantly improve this type of visual cortex training using a new set of specific glasses and a new method of using them.

[0007] US document 3705760 A describes protective goggles integrated into a face mask, designed to protect the wearer's eyes and face from splashes, impurities, intense light, cold, and wind. Description of the invention

[0008] The object of the present invention is therefore to overcome the drawbacks of the prior art by proposing a new set of vision training glasses that simultaneously stimulates vertical, horizontal, lateral, and peripheral vision while promoting the cooperative functioning of the different brain centers. Another object of the present invention is to propose a new method for training the visual cortex based on the use of the aforementioned set of glasses within a dynamic training framework aimed at the holistic recovery of optimal vision.

[0009] Since it is not possible to simultaneously retrain the different brain skills involved in vision, the new set of glasses of the invention and its associated training method make it possible to successively work each part of the brain involved in vision using different separate pairs of glasses.

[0010] Vision training using the invention is not only for people whose eyesight has declined with age, for those with myopia and astigmatism, and for anyone else with a visual impairment, but it can also be used preventively or to provide even better vision to people without any visual impairment.

[0011] The objects assigned to the invention are reached with the aid of a set of vision training glasses by occultation of a part of the visual field, characterized in that it comprises several glasses different from each other intended to be used successively and each comprising an opaque surface covering the whole field of vision and in which is provided at least one transparent part allowing vision, this at least one transparent part being different for each of the glasses, the at least one transparent part being in the form of a longitudinal transparent slit of at least 1.5 millimeters wide or in the form of a continuous transparent surface of at least 50 square millimeters.

[0012] This set of vision training glasses is preferably used in conjunction with pinhole glasses of the known type from which it differs, in particular in that the transparent parts of the glasses according to the invention are larger in size than those of known pinhole glasses.

[0013] The set of glasses includes at least two glasses chosen from the following: training glasses for aligning points on a horizontal line in each eye, these glasses having a single transparent part in the form of a continuous horizontal slit of vision located at the level of the horizontal axis of the pupils of a subject looking straight ahead; training glasses for aligning points on a vertical line in each eye, these glasses having only two transparent parts provided, each in the form of a continuous vertical slit of vision located at the level of the vertical axis of one of the pupils of a subject looking straight ahead; training glasses for vision in the medial field of each eye, these glasses having a single transparent part in the form of a central vertical slit of vision at least 10 millimeters wide and located medianally between the vertical axis of the two pupils of a subject looking straight ahead;vision training glasses in the lateral field of each eye, these glasses having only two transparent parts each in the form of a lateral vertical viewing slit at least 10 millimeters wide and offset laterally from the vertical axis of each of the pupils of a subject looking straight ahead;vision training glasses in the supero-external field of the right eye and the infero-external angle of the left eye, these glasses having only two transparent parts, the transparent part associated with the right eye being in the form of a transparent upper right lateral area offset to the right with respect to the vertical axis of the right pupil of a subject looking straight ahead and offset upwards with respect to the horizontal axis of that same pupil, and the transparent part associated with the left eye being in the form of a transparent lower left lateral area offset to the left with respect to the vertical axis of the left pupil of a subject looking straight ahead and offset downwards with respect to the horizontal axis of said left pupil;vision training glasses in the supero-external field of the left eye and the infero-external angle of the right eye, these glasses having only two transparent parts, the transparent part associated with the left eye being in the form of a transparent upper left lateral area offset to the left with respect to the vertical axis of the left pupil of a subject looking straight ahead and offset upwards with respect to the horizontal axis of that same pupil, and the transparent part associated with the right eye being in the form of a transparent lower right lateral area offset to the right with respect to the vertical axis of the right pupil of a subject looking straight ahead and offset downwards with respect to the horizontal axis of said right pupil;and converging vision training glasses for both eyes, these glasses having only two transparent parts, each centered on the pupils of a subject looking straight ahead, each of the two transparent parts being extended forwards by an opaque hollow tube attached to the glasses, these two opaque hollow tubes converging towards each other at their free ends.

[0014] According to one example of an implementation of the invention, the set of glasses comprises at least three, preferably four, more preferably five glasses chosen from the previous training glasses.

[0015] According to a further example of implementation of the invention, the set of glasses comprises at least six, preferably seven glasses chosen from the training glasses described above.

[0016] According to one example of an implementation of the invention, the horizontal viewing slit of the training glasses for aligning points on a horizontal line has a width L1 between 1 and 5 millimeters, preferably between 2 and 4 millimeters, and more preferably substantially equal to 3 millimeters.

[0017] According to another example of implementation of the invention, the vertical viewing slits of the training glasses for aligning points on a vertical line each have a width L2 of between 1.5 and 5 millimeters, preferably between 2 and 4 millimeters, and more preferably substantially equal to 3 millimeters.

[0018] According to a further example of an implementation of the invention, the central vertical viewing slit of the medial field vision training glasses is located at a distance L3 from the vertical axis of each of the two pupils, this distance L3 being between 5 and 30 millimeters, preferably between 10 and 20 millimeters, and more preferably substantially equal to 15 millimeters.

[0019] According to one exemplary implementation of the invention, each of the wide vertical lateral viewing slits of the lateral field vision training glasses is located at an external lateral distance L4 from the vertical axis of each of the two pupils, this distance L4 being between 1.5 and 10 millimeters, preferably between 3 and 7 millimeters, and more preferably substantially equal to 5 millimeters.

[0020] According to another example of an implementation of the invention, for vision training glasses in the supero-external and infero-external fields of the eyes: the transparent part forming a superior lateral transparent zone is located at a vertical distance L5' or L6' above the horizontal axis of the pupils, this vertical distance L5' or L6' being between 1.5 and 5 millimeters, preferably between 2 and 4 millimeters, and more preferably approximately equal to 3 millimeters, and located at a lateral distance L5" or L6" offset outwards with respect to the vertical axis of each of the two pupils, this lateral distance L5" or L6" being between 3 and 20 millimeters, preferably between 5 and 15 millimeters, and more preferably approximately equal to 10 millimeters;and the transparent part forming a lower lateral transparent zone is located at a vertical distance L5' or L6' below the horizontal axis of the pupils, this vertical distance L5' or L6' being between 1.5 and 5 millimeters, preferably between 2 and 4 millimeters, and more preferably approximately 3 millimeters, and located at a lateral distance L5" or L6" offset outwards from the vertical axis of each of the two pupils, this lateral distance L5" or L6" being between 3 and 20 millimeters, preferably between 5 and 15 millimeters, and more preferably approximately 10 millimeters.

[0021] According to a further example of implementation of the invention, the two transparent parts of the convergence vision training glasses have respective horizontal dimensions L7a and vertical dimensions L7b between 5 and 40 millimeters, preferably between 10 and 30 millimeters, and more preferably substantially equal to 22 millimeters.

[0022] According to one example of an implementation of the invention, the two transparent parts of the convergence vision training glasses are circular in shape with a diameter L7a equal to L7b and between 5 and 40 millimeters, preferably between 10 and 30 millimeters, and more preferably substantially equal to 22 millimeters, and in that the opaque hollow tubes have a round section of the same internal diameter L7a.

[0023] According to one example of an implementation of the invention, the two transparent parts (30) of the convergence vision training glasses (1, 17) are oval, square or otherwise polygonal in shape and the opaque hollow tubes (18) have a cross-section of the same shape.

[0024] According to another example of implementation of the invention, the opaque hollow tubes of the convergence vision training glasses have an average length L7' of between 20 and 100 millimeters, preferably between 40 and 80 millimeters, and more preferably between 55 and 65 millimeters.

[0025] According to another additional implementation of the invention, the opaque hollow tubes of the convergence vision training glasses converge towards each other at their free end so that their axes of revolution intersect at a convergence distance L7" from the vertical plane passing through the two pupils of the subject, this distance L7" being between 50 and 300 millimeters, preferably between 100 and 200 millimeters, and more preferably between 140 and 160 millimeters.

[0026] According to one embodiment of the invention, the opaque surface is obtained by adding vision-blocking patches attached to transparent lenses. Thus, it is possible, for example, to convert existing glasses into glasses according to the invention.

[0027] According to another embodiment of the invention, the at least one transparent part is a transparent material or an absence of material provided within the opaque surface. Thus, in the case where the transparent part is an absence of material provided within the opaque surface, it is possible to manufacture the glasses according to the invention from an opaque material, with recesses provided in the material to form the at least one transparent part.

[0028] The objects assigned to the invention are also achieved using a vision training method, characterized in that it consists of successively wearing each of the glasses from the set of glasses as described above for a limited time.

[0029] According to one example of implementation of the method of the invention, each of the glasses in the set of glasses is worn for a minimum period of one minute, preferably for a minimum period of two minutes.

[0030] According to another embodiment of the invention, the method consists of successively wearing each of the glasses from the set, as well as conventional pinhole glasses, for a limited time. Indeed, for greater effectiveness, the vision training method of the invention is preferably carried out in conjunction with regular use of conventional pinhole glasses for a similar duration.

[0031] The advantages of the present invention are particularly numerous. Indeed, this set of glasses and its use advantageously enhances vertical, horizontal, lateral and peripheral vision while promoting the cooperative functioning of the brain's centers.

[0032] Whereas conventional methods merely re-tonify the eye muscles and / or the cooperative brain systems associated with sight in a static manner, the glasses set of the invention and its method of use enable dynamic training for a holistic recovery of optimal vision. Through the glasses set of the invention and its method of use, it is possible to successively re-educate the different skills involved in vision by exercising each system involved in vision using distinct and specific glasses.

[0033] Inexpensive, requiring no medical prescription and simple and undemanding to use, the set of glasses of the invention thus makes it possible not only to improve one's vision at low cost, but also to eventually do without corrective glasses or eye surgery. Brief description of the drawings

[0034] Other features and advantages of the present invention will become more apparent upon reading the following description, made with reference to the accompanying drawings, given by way of non-limiting examples, in which: there figure 1 is a schematic front view of training glasses for aligning points on a horizontal line for each eye according to the invention; the figure 2 is a schematic front view of training glasses for aligning points on a vertical line for each eye according to the invention. figure 3 is a schematic front view of vision training glasses in the medial field of each eye according to the invention; the figure 4 is a schematic front view of vision training glasses in the lateral field of each eye according to the invention; the figure 5is a schematic front view of vision training glasses in the supero-external field of the right eye and the infero-external angle of the left eye according to the invention; the figure 6 is a schematic front view of vision training glasses in the supero-external field of the left eye and the infero-external angle of the right eye according to the invention; the figure 7 is a schematic front view of convergence training glasses for both eyes according to the invention; and the figure 8 is a schematic top view of the training goggles of the figure 7 in which the opaque hollow tubes are shown in cross-section. Method(s) of embodiment of the invention

[0035] Structurally and functionally identical elements present on several distinct figures are assigned the same numerical or alphanumeric reference.

[0036] The invention relates to a set of vision training glasses in which each lens (1) of said set of glasses covers a different part of the field of vision for dynamic training and holistic recovery of optimal vision. Thus, these are not corrective glasses of a medical nature but vision training glasses (1) that can be purchased and marketed by anyone without contraindication.

[0037] Indeed, the inventor discovered that pinhole vision training glasses only allow for partial and static training of the eye muscles and visual cortex. Through extensive studies, the inventor discovered that it was possible to significantly improve this type of visual cortex training using a new set of specialized glasses and a new method of using them.

[0038] This set of glasses comprises various vision training glasses (1), each having at least one opaque part (2) that blocks vision and at least one transparent part (3) that allows vision. These glasses (1) are not pinhole glasses; the transparent part is not in the form of a hole, but rather either in the form of a longitudinal transparent slit (4) or in the form of at least one large continuous transparent surface (5).

[0039] The at least one longitudinal transparent slit (4) has a width of at least 1.5 millimeters, preferably approximately 3 millimeters wide, while the at least one large continuous transparent surface (5) has an area of ​​at least 50 square millimeters. A large transparent surface is understood to be a continuous, single-piece surface, distinct from a collection of small unit surfaces.

[0040] At least one longitudinal transparent slit (4) preferentially crosses the opaque part (2) from one edge to another.

[0041] Each of the vision training glasses (1) of the invention allows the eye muscles and visual cortex to be trained in different ways, each time different, so that all the eye muscles and all parts of the visual cortex and brain involved in vision are stimulated, trained and strengthened.

[0042] As will be explained later, each of the vision training glasses (1) of the invention must be worn successively for a given duration for optimal training. It is, of course, possible to use only some of the glasses in the set of glasses of the invention, but the result is consequently much less effective. Indeed, this invention relates to a set of glasses composed of several different vision training glasses (1) which must all be worn successively, and not to individual glasses intended for use on their own.

[0043] The set of glasses of the invention comprises at least three, preferably four, more preferably five different vision training glasses (1). For optimal vision training and improvement, the set of glasses of the invention comprises at least six, preferably seven different vision training glasses (1).

[0044] Thus, the vision training glasses set (1) according to the invention preferably comprises seven vision training glasses (1), which are all different.

[0045] The vision training glasses set (1) according to the invention comprises several different vision training glasses (1) which are described below with reference to figures 1 to 8 .

[0046] In these figures the vertical axis (6) and the horizontal axis (7) of each of the pupils of a subject looking straight ahead are represented by a broken line, the position of each pupil being symbolized by a black circle (8).

[0047] Indeed, for better efficiency, each of the vision training glasses (1) of the invention must be sized to fit the position of the subject's eyes so that the opaque parts (2) and the transparent parts (3) are correctly positioned in relation to his pupils.

[0048] The lenses (9) of the vision training glasses (1) are for example made of plastic or mineral material, while the frame (10) is for example made of plastic or metal material.

[0049] The lenses (9) of the glasses (1) of the invention are preferably joined so as to form a single mask-type lens (9).

[0050] To form the opaque parts (2) that block vision, the lenses (9) of the spectacles (1) can, for example, be coated with an opaque material, such as paint or film. This material must block vision. It can, for example, be black.

[0051] According to one variant of the invention, the opaque parts (2) can be made up of removable covers which are attached to completely transparent glasses.

[0052] The first training glasses (1, 11) according to the invention are represented schematically and in a simplified manner on the figure 1 .

[0053] These glasses (1, 11) have a single transparent part (3) in the form of a single continuous horizontal viewing slit (21) located at the horizontal axis (7) of the two pupils of a subject looking straight ahead.

[0054] The horizontal viewing slit (21) extends preferentially over the entire width of the lenses (9) and / or the opaque part (2).

[0055] The horizontal viewing slit (21) has a width L1 between 1.5 and 5 millimeters, preferably between 2 and 4 millimeters, and more preferably substantially equal to 3 millimeters.

[0056] These first training glasses (1, 11) are intended to stimulate and exercise the cooperative brain systems responsible for aligning points on a horizontal line in each eye in order to make the systems managing horizontal lines cooperate intensively with all other vision centers.

[0057] The second pair of training glasses (12) according to the invention are shown schematically and in a simplified manner on the figure 2 .

[0058] These glasses (12) have only two transparent parts (3) each provided in the form of a continuous vertical viewing slit (22) each located at the level of the vertical axis (6) of one of the pupils of a subject who is looking straight ahead.

[0059] Each vertical viewing slit (22) extends preferentially over the entire height of the lenses (9) and / or the opaque part (2).

[0060] Each vertical viewing slit (22) has a width L2 between 1.5 and 5 millimeters, preferably between 2 and 4 millimeters, and more preferably substantially equal to 3 millimeters.

[0061] These second training glasses (12) are intended to stimulate and work the cooperative brain systems responsible for aligning points on a vertical line in each eye in order to make the vertical line management systems cooperate intensively with all other vision centers.

[0062] The third training glasses (13) according to the invention are represented schematically and in a simplified manner on the figure 3 .

[0063] These glasses (13) have a single transparent section (3) in the form of a wide, central, vertical viewing slit (23) located centrally between the vertical axis (6) of the two pupils of a subject looking straight ahead. Thus, this wide, central, vertical viewing slit (23) is provided in the middle section of the glasses (13), along the vertical axis of the nose, and also obscures the area in front of the pupils, forcing the subject to squint.

[0064] This central vertical viewing slit (23) is considered wide because it has a width of at least 10 millimeters, which differentiates it from the thin transparent horizontal (21) and vertical (22) slits which have a width preferably less than or equal to 5 millimeters.

[0065] The wide central vertical viewing slit (23) extends preferentially over the entire height of the lenses (9) and / or the opaque part (2). It is located at a distance L3 from the vertical axis (6) of each of the two pupils, this distance L3 being between 5 and 30 millimeters, preferably between 10 and 20 millimeters, and more preferably approximately equal to 15 millimeters.

[0066] These third training glasses (13) are designed to force the subject to use alternately the medial field of each eye to form a complete image so that the two hemispheres of the brain actively collaborate to form a complete image of the environment.

[0067] The fourth training glasses (14) according to the invention are represented schematically and in a simplified manner on the figure 4 .

[0068] These glasses (14) have only two transparent parts (3) each in the form of a wide lateral vertical viewing slit (24) located laterally offset outwards from the vertical axis (6) of each of the pupils of a subject looking straight ahead.

[0069] These glasses (14) therefore have a configuration that is substantially the opposite of those of the third glasses (13), with an opaque median band (25) which also obscures the part located in front of the pupils.

[0070] Each large lateral vertical viewing slit (24) is located at an external lateral distance L4 from the vertical axis of each of the two pupils, this distance L4 being between 1.5 and 10 millimeters, preferably between 3 and 7 millimeters, and more preferably substantially equal to 5 millimeters

[0071] These fourth training glasses (14) are designed to force the subject to use alternately the lateral field of each eye to form a complete image so that the two hemispheres of the brain actively collaborate to form a complete image of the environment.

[0072] The fifth training glasses (15) according to the invention are represented schematically and in a simplified manner on the figure 5 .

[0073] These glasses (15) have only two transparent parts (3), namely an upper right transparent part (26) and a lower left transparent part (27). Thus, these glasses (15) almost completely obstruct both visual fields except for the upper outer corner of the right eye and the lower outer corner of the left eye.

[0074] In these fifth training glasses (15), the transparent part (3) associated with the right eye is in the form of a transparent upper right lateral area (26) shifted to the right with respect to the vertical axis (6) of the right pupil of a subject looking straight ahead and shifted upwards with respect to the horizontal axis of that same pupil, and the transparent part (3) associated with the left eye is in the form of a transparent lower left lateral area (27) shifted to the left with respect to the vertical axis (6) of the left pupil of a subject looking straight ahead and shifted downwards with respect to the horizontal axis of said left pupil.

[0075] The transparent portion (3) forming the upper right lateral transparent zone (26) is located at a vertical distance L5' above the horizontal axis (7) of the pupils, with L5' being between 1.5 and 5 millimeters, preferably between 2 and 4 millimeters, and more preferably approximately 3 millimeters. This upper right lateral transparent portion (26) is located at a lateral distance L5" offset outwards (i.e., to the right) from the vertical axis (6) of each of the two pupils, with L5" being between 3 and 20 millimeters, preferably between 5 and 15 millimeters, and more preferably approximately 10 millimeters.

[0076] The transparent portion (3) forming the lower left lateral transparent zone (27) is located at a vertical distance L5' below the horizontal axis (7) of the pupils, with L5' being between 1.5 and 5 millimeters, preferably between 2 and 4 millimeters, and more preferably approximately 3 millimeters. This lower left lateral transparent portion (27) is located at a lateral distance L5" offset outwards (i.e., to the left) from the vertical axis (6) of each of the two pupils, with L5" being between 3 and 20 millimeters, preferably between 5 and 15 millimeters, and more preferably approximately 10 millimeters.

[0077] These fifth training glasses (15) are designed to force the subject to move their head and body dynamically, allowing the brain to reconstruct a complete image of the environment. With these glasses (15), the unusual fragmentation of the image induces novel stimulation of numerous centers and areas in both cerebral hemispheres to reconstruct a coherent image. One of the unique features of these glasses (15) is that they require the cooperation of both cerebral hemispheres and the corpus callosum, the only neural pathway between the two cerebral hemispheres.

[0078] The sixth training glasses (16) according to the invention are represented schematically and in a simplified manner on the figure 6 .

[0079] These glasses (16) have only two transparent parts (3), namely a lower right transparent part (28) and an upper left transparent part (29). Thus, these glasses (16) almost completely obstruct both visual fields except for the upper outer corner of the right eye and the lower outer corner of the left eye.

[0080] These sixth training glasses (16) are close to the fifth glasses (15) because they are their mirror image.

[0081] In these sixth training glasses (16) the transparent part (3) associated with the right eye is in the form of a lower right lateral transparent area (28) shifted to the right with respect to the vertical axis (6) of the right pupil of a subject looking straight ahead and shifted downwards with respect to the horizontal axis (7) of said right pupil and the transparent part (3) associated with the left eye is in the form of a upper left lateral transparent area (29) shifted to the left with respect to the vertical axis (6) of the left pupil of a subject looking straight ahead and shifted upwards with respect to the horizontal axis (7) of said same pupil.

[0082] The transparent portion (3) forming the lower right lateral transparent zone (28) is located at a vertical distance L6' below the horizontal axis (7) of the pupils, with L6' being between 1.5 and 5 millimeters, preferably between 2 and 4 millimeters, and more preferably approximately 3 millimeters. This lower right lateral transparent portion (3) (28) is located at a lateral distance L6" offset outwards (i.e., to the right) relative to the vertical axis (6) of each of the two pupils, with L6" being between 3 and 20 millimeters, preferably between 5 and 15 millimeters, and more preferably approximately 10 millimeters.

[0083] The transparent portion (3) forming the upper left lateral transparent zone (29) is located at a vertical distance L6' above the horizontal axis (7) of the pupils, with L6' being between 1.5 and 5 millimeters, preferably between 2 and 4 millimeters, and more preferably approximately 3 millimeters. This upper left lateral transparent portion (29) is located at a lateral distance L6" offset outwards (i.e., to the left) from the vertical axis (6) of each of the two pupils, with L6" being between 3 and 20 millimeters, preferably between 5 and 15 millimeters, and more preferably approximately 10 millimeters.

[0084] The sixth training glasses (16) have the same purpose as the fifth glasses (15) and work in the same way, but by reversing the way each eye and therefore each cerebral hemisphere works.

[0085] The seventh training glasses (17) according to the invention are represented schematically and in a simplified manner on the figures 7 and 8 .

[0086] These glasses (17) have only two transparent parts (30) each centered on the pupils of a subject who is looking straight ahead.

[0087] Each of the two transparent parts (30) is extended forward by an opaque hollow tube (18) attached to the glasses, these two opaque hollow tubes (18) converging towards each other at their free end.

[0088] Each of the two transparent parts (30) of the convergence vision training glasses (1) has a width L7a and a height L7b each between 5 and 40 millimeters, preferably between 10 and 30 millimeters, and more preferably approximately equal to 22 millimeters. They are preferably circular in shape with a diameter L7a equal to L7b and between 5 and 40 millimeters, preferably between 10 and 30 millimeters, and more preferably approximately equal to 22 millimeters.

[0089] Preferably the opaque hollow tubes (18) have a round section of the same internal diameter L7a as that of the two circular transparent parts (30).

[0090] The opaque hollow tubes (18) have an average length L7' of between 20 and 100 millimeters, preferably between 40 and 80 millimeters, and more preferably between 55 and 65 millimeters.

[0091] The opaque hollow tubes (18) converge towards each other at their free end so that their axes of revolution (19) intersect at a convergence distance L7" from the vertical plane (20) passing through the two pupils of the subject, this distance L7" being between 50 and 300 millimeters, preferably between 100 and 200 millimeters, and more preferably between 140 and 160 millimeters.

[0092] These seventh training glasses (17) guide the gaze along the axis of each pupil and force the subject to look through the opaque hollow tubes (18). These opaque hollow tubes (18) are oriented so as to allow only the points seen by the two eyes in convergence to be seen.

[0093] These seventh training glasses (17) are designed to improve the subject's convergence and require them to perform significant tilting movements of the head and upper body in all planes of space. The goal is to perceive the environment in order to recreate a coherent image. Thus, these training glasses (17) intensely re-engage the visual system, the balance system, the body's spatial proprioception (primarily of the head), and oculocephalogyry, that is, the coupling of eye and head movement control in relation to vision. Indeed, in modern urban life, these different systems are hardly ever used together, even though they play an important role, among other things, in vision.

[0094] It should be noted that the invention relates to a set of glasses (1) comprising several glasses (1) different from each other intended to be used successively, this set preferably comprising at least glasses such as the first training glasses (11) shown in the figure 1 This set of glasses (1) may also preferentially include glasses such as the second training glasses (12) shown on the figure 2 , glasses such as the third training glasses (13) shown on the figure 3 , glasses such as the fourth training glasses (14) shown on the figure 4 , glasses such as the fifth training glasses (15) shown on the figure 5 , glasses such as the sixth training glasses (16) shown on the figure 6, and / or glasses such as the seventh training glasses (17) shown on the figures 7 and 8 .

[0095] Thus, the set of glasses (1) of the invention is characterized in that it preferably comprises at least one of the glasses such as those described above and represented on the figures 1 to 8 , and at least one other pair of vision training glasses (1). Since all the glasses (1) in the set of glasses (1) of the invention are different, these other glasses may be glasses such as those described above and shown in the figures 1 to 8 , or other training glasses of a different type.

[0096] According to one embodiment of the invention, the opaque surface can be obtained by adding vision-blocking panels that are attached to transparent lenses. Conventional eyeglasses can thus be converted into eyeglasses according to the invention by gluing, clipping, or attaching opaque sections to the lenses or frame in any manner.

[0097] However, this solution is not recommended for prescription glasses.

[0098] It should be noted that the at least one transparent portion may be made of transparent material, for example, glass or transparent plastic. It may also be formed by the absence of material in the opaque surface, particularly when this opaque surface is a single piece of opaque material. Indeed, it is easy and inexpensive to manufacture the glasses according to the invention from opaque plastic, with recesses provided in said plastic to form the at least one transparent portion.

[0099] As mentioned previously, the invention also relates to a complete vision training method based on the use of the training glasses set of the invention.

[0100] This vision training method is based on wearing each of the glasses (1) from the set of glasses as described above for a limited time.

[0101] Preferably, wearing each pair of glasses (1) is combined with body and head movements of the subject to perform dynamic vision training, which has proven to be much more effective than static training. It is therefore advisable to use the set of glasses of the invention while walking and focusing on distinct points in space.

[0102] Similarly, wearing each of the glasses (1) is preferentially associated with an environment rich in visual stimuli and obstacles.

[0103] When using the set of glasses of the invention to regain optimal vision, each pair of glasses (1) is worn successively at least three times a week, preferably once a day, until optimal vision is regained. Each pair of glasses (1) is worn for a minimum of one minute, preferably for a minimum of two minutes. Thus, a daily training session preferably takes about fifteen minutes, i.e., 2 x 7 minutes, plus a few seconds to change glasses (1) each time.

[0104] Preferably, at the beginning of the training period, each pair of glasses (1) is worn daily for two to five minutes a day in order to respect the feeling of eye fatigue, this duration can then be extended when the user has trained well, for example up to a duration of five to ten minutes a day.

[0105] Once optimal vision has been restored, the glasses can be used less frequently for maintenance purposes. Similarly, if the individual already has optimal vision, the glasses can be used preventively, particularly from the age of forty onwards. In both cases, the glasses (1) of the glasses set of the invention are worn at least once a week, preferably twice a week.

[0106] It should be noted that this training method is primarily intended for people whose vision has declined with age, suffering from presbyopia, but also myopia and / or astigmatism. It is also suitable for people with any other impairment, including visual impairment, as it will improve the overall performance of the visual system. Finally, this training method is also suitable for anyone with good vision who wishes to further improve it, which notably allows them to try to achieve better than 20 / 20 vision in each eye.

[0107] Depending on the subject's initial visual impairment, the training process may eventually allow a subject to recover sufficient vision so that they no longer need to wear corrective glasses.

[0108] It should be noted that the invention relates to a training method that is not intended to cure any disease, but rather to improve an individual's vision through regular training, even if they already have good eyesight. The training method of the invention relies solely on the use of special glasses and does not involve any essentially biological methods, such as using a weight bench or an exercise book designed to improve memory.

[0109] This vision training method is not intended to correct physiological defects of the eye, such as a geometric defect causing myopia, astigmatism, or hyperopia, which would have a therapeutic purpose. Rather, the vision training method of the invention aims to train the user's brain to improve the visual cortex's ability to generate a good-quality image, for example, to improve the eyesight of a user without vision problems, or to compensate for any physiological defects of the eye, without attempting to correct these defects.

[0110] The training glasses of the invention must also be distinguished from therapeutic glasses, which are corrective glasses. Indeed, the training glasses of the invention have no corrective purpose.

[0111] The glasses system of the invention advantageously trains the visual cortex to better process the visual information it receives, thereby improving vision. By successively using different training glasses, the invention allows for the stimulation of vertical, horizontal, lateral, and peripheral vision while promoting the cooperative functioning of the various brain centers. The invention thus offers dynamic training for a holistic recovery of optimal vision, which may, for example, eventually eliminate the need for glasses, contact lenses, or any other similar device, without any medical or biological treatment or surgery.

[0112] It should be noted that the training method of the invention should preferably be used in conjunction with the wearing of conventional pinhole glasses. The user should therefore regularly wear both pinhole glasses and glasses from the set of glasses of the invention, preferably for two to five minutes per exercise session at the beginning of training, and then for five to ten minutes per exercise session once the user experiences less fatigue from wearing the glasses of the invention. This exercise is preferably performed daily for vision rehabilitation, and then weekly, preferably twice a week, for maintenance or preventative use.

[0113] The glasses can be worn in any order, the important thing being to wear successively and regularly all the glasses from the set of glasses of the invention and the pinhole glasses for a preferably similar duration.
