The glasses and the training method of the utility model can provide very uniform and stable peripheral degrees and also avoid the degree change caused by the partition.

Description

Training glasses and training system thereof
Technical Field
The utility model relates to the field of vision correction training, in particular to training glasses and a training system thereof.
Background
When the eyes see the front sighting target, the peripheral sighting target images can be projected to the opposite peripheral retina at the same time, and the peripheral sighting target images and the peripheral retina are not focused on the retina at the same time. For example: when the central training optotype is clearly focused in the center of the macular region, the peripheral image is not focused on the peripheral retina, but is focused behind the retina, because the peripheral retina is relatively anterior and close to the crystalline lens. Clinically, when the peripheral optotype is focused on the posterior retina, it is called "peripheral retinal hyperopic defocus".
The damage of the hyperopic defocus phenomenon at the periphery of the retina to vision:
when a myopia person looks at a distant vision, the myopia person can wear a concave lens for correcting myopic ametropia in order to focus distant central vision, and the central vision mark and a peripheral vision mark are refracted through a cornea and a crystalline lens, so that the central vision mark and a nearby focusing point are moved backwards to be overlapped with a macular retina to obtain clear central vision, but the peripheral vision at a distant position is moved backwards, and the phenomenon of hyperopia defocusing at the periphery of the retina is aggravated.
More disadvantageously, when the myopic person continues to read and work at close distances while wearing concave glasses that correct myopic ametropia, the central and peripheral optotypes are brought closer to the eye and therefore focus more posteriorly away from the retina, causing an artificial hyperopic ametropia and more severe hyperopic defocus around the retina.
The unfocused central and peripheral targets in the above situation stimulate the center of vision of the brain, which activates the center of the midbrain's near reflex pathway to obtain a relatively sharp target view, causing contraction of the ciliary muscle (which may cause spasticity over time), increasing the lens surface curvature and anterior-posterior diameter (which persists when the ciliary muscle is spastic), and producing increased accommodation (which persists when the ciliary muscle is spastic) to focus the target view. Focusing of the central view is generally achieved only because the focusing of the peripheral visemes requires more adjustment, which in turn causes the focusing of the central view to move forward in front of the central retina, resulting in a new round of myopic ametropia. Therefore, the occurrence and development of pseudomyopia and true myopia can be easily caused and aggravated by wearing concave glasses with myopic ametropia to correct myopia, and the degree of myopia is rapidly increased, and is easily increased by one or two hundred degrees every year.
The mainstream brands for manufacturing lenses for coping with peripheral hyperopic defocus include Zeiss, EYELU and Haoya.
The traditional progressive addition lens only adds convex power gradually under the lens, and aims to resist presbyopia when the visual axis moves downwards for close reading. Originally the purpose was not to counteract peripheral hyperopic defocus.
The design of the "zeiss grown" lens is a peripheral 360 progressive slice design. The progressive representative power varies continuously so that it does not exactly match the distance vision defocus power of each range of the upper periphery. When the central axis of the eye moves, it is less likely to match the distance-dependent defocus values for each range of the upper periphery. In addition, the vertical gradient and the horizontal gradient are obviously different due to the manufacturing technology, so that additional image deformation is caused. It is not a good peripheral hyperopic defocus design.
The 'star interest control according to the visual path' lens is designed in a mode of peripheral concentric circles, the more the additional power is, the higher the additional power is, the intervals are formed among the concentric circles, and the spaced power is the same as the central power of the lens. The progressive design is discontinuous, the degree changes continuously and the fluctuation range is large, so that the image deforms continuously, and the progressive design is not good in peripheral hyperopia resistance. When the central power of the myopic lens appears in the periphery, the degree of peripheral hyperopic defocus is increased, which is not favorable for resisting the peripheral hyperopic defocus.
The design of the 'Haoyanxinle' lens is that the periphery is set to be hexagonal, 396 convex mirrors with +3.5D are added, and the separation power between the convex mirrors is the central lens power. This is an intermittent non-progressive design, where the peripheral power varies widely between +3.5D and the central power, resulting in constant distortion of the image, and furthermore, the hexagonal boundaries are not ideal or well resistant to peripheral hyperopic defocus relative to a 360 smooth and coherent peripheral field of view. When the central power of the myopic lens appears in the periphery, the degree of peripheral hyperopic defocus is increased, which is not favorable for resisting the peripheral hyperopic defocus.
The lenses do not solve the problem of the wearer's hyperopic defocus in the central range when looking near, which increases myopia.
SUMMERY OF THE UTILITY MODEL
In view of the above problems, the present invention provides special training glasses for canceling peripheral hyperopic defocus for near or far scenes, which are suitable for the trainees who do not wear or wear the glasses for near vision. The person to be trained who wears the myopia glasses needs to keep wearing the myopia glasses for training.
The utility model discloses a pair of training glasses, which comprises lenses and is characterized in that the lenses comprise a first refraction training area and a second refraction training area, the first refraction training area is formed into a closed area at the center position of the lenses, the second refraction training area is formed into an area except the first refraction training area, and the second refraction training area is one degree of +1.0D to + 4.5D.

and the transition region is positioned between the first refraction training region and the second refraction training region, the width of the transition region is 0-10mm, and the power is between the power of the first refraction training region and the power of the second refraction training region.

the screen isolation area comprises a front plate unit and a rear plate unit which are superposed, scales are arranged on the upper edges of the front plate unit and the rear plate unit, and the rear plate unit adjusts the width of the screen isolation area along with the sliding of the distance adjusting unit along the horizontal direction. The new design of the present invention also allows for maintaining the pairing of the peripheral hyperopic defocus over a greater range as the central eye axis moves, so that a more stable effect against the peripheral hyperopic defocus can be achieved.
Because the lens is non-progressive and has no power partition, very uniform and stable peripheral power can be provided, and the power change caused by the partition is avoided. Meanwhile, the central degree is prevented from appearing at the periphery, so that the adverse factor of peripheral hyperopic defocus is not increased, and the peripheral hyperopic defocus can be effectively resisted.

There are different definitions of the macula in medicine, and we adopt the definition commonly used in clinic, the macula is located in the central part of the retina, and occupies the central 0-25 ° range of the visual field (generally, the retina without cone photoreceptor cells when more than 25 °), and the peripheral retina and the opposite visual field are beyond 25 °. The peripheral retina has no cone photoreceptor cells and the columnar photoreceptor cell density drops significantly from 20 ° outward, which does not contribute to stereovision. Important functions of peripheral vision are: recognition of common structures and forms, distinguishing similar forms and actions, creates a sense of visual background. The perception of central vision plus the contribution of peripheral vision constitute a panoramic detailed field of view seen by the daily eye.
The peripheral retina, which contributes clinically significantly to overall vision, is referred to as the anterior-posterior range (about 25-60) of the equator (about 43), due to the spherical morphology of the eye, and the relationship between the size of the pupil and the relative positions of the lens and the peripheral retina in daily life. Since peripheral hyperopic defocus also causes and exacerbates the formation and progression of myopia, weakening or counteracting the peripheral hyperopic defocus can help inhibit the formation of pseudomyopia and true myopia.
Based on the above theoretical basis, the applicant has designed two training lenses for near-and far-view scenes, which are described in detail below.
Please refer to fig. 1, which is a schematic structural diagram of a first training lens 100 for near field use according to the present invention.
The first training lens 100 is suitable for use in a 360 ° bifocal lens for reading at near distances, and for use in operations at near distances, including reading (computers, books, etc.) and vision training.
The lens area of the first training lens 100 is divided into a first refractive training area 101 and a second refractive training area 102. Wherein the first refraction training area 101 is formed as a closed area of the lens center position, and the second refraction training area 102 is formed as an area other than the first refraction training area 101. Since the first refractive training area 101 is a closed area, i also refer to the first training lens 100 as a special 360 bifocal lens. In addition, the left and right width of the first training lens 100 is about 25 to 60mm (not limited to this range), and the up and down height is about 25 to 40mm (not limited to this range).
In view of increasing the visual comfort of the visual axis as it transitions from the inner zone to the outer zone, the configuration shown in figure 1 adds a transition zone 103 between the first and second refractive training zones 101 and 102 to buffer the difference in power between the inner and outer zones. The transition zone 103 satisfies: width: 0-10 mm; the power range is such that the minimum power is equal to or greater than the power of the first dioptric training region 101 and the maximum power is equal to or less than the power of the second dioptric training region 102.
In the preferred embodiment shown, the first refractive training area 101 is a circular shape, i.e., a closed area with a diameter of 13mm (not limited thereto, in the range of 5-20 mm), and has a central power of +1.50D, in the range of +0.75D to + 3.00D. The first refractive training area 101 is a colorless lens, and the second refractive training area 102 is a lens area other than the first refractive training area 101, which is purple and has a depth of 25% (not limited thereto, in the range of 10% to 50%).
In the preferred embodiment, the second refractive training area 102 is purple for reasons and benefits of: the non-glare, shortest wavelength in visible light, approximately equal to the effect of adding +0.15D to red light, with a peripheral power of +3.50D, ranging from +1.5D to +4.50D, with a base-in prism.
The ideal distance for near viewing should be maintained at 35cm, and myopia is likely to be induced by too close viewing. The size and speed of the adjusting ability of people are different from person to person and need assistance. Clinically, the degree of +1.5D can meet the needs of most people, and meanwhile, the myopia is prevented from being caused or increased by excessively using the adjustment of the nearsighted person, and the nearsighted person can be clearly seen by lowering the head of the nearsighted person or pulling the book close. Therefore, the first refraction training area 101 is usually designed to have a starting power of + 1.5D.
For the second refractive training region 102, to counteract the peripheral hyperopic defocus, a +2.0D is superimposed over the +1.5D range, i.e., starting at +3.5D, which is the starting point for the patient to respond more comfortably in the clinic. Depending on the degree of accommodation and the response after training, the power of the second refractive training area 102 may be increased or decreased to between +1.5D and + 4.5D.
In the near distance work, for the person to be trained who does not wear or wears the myopia glasses, the first training lens 100 with the structure is directly worn by the person to be trained who does not wear the myopia glasses, and the person to be trained who wears the myopia glasses can be directly sleeved (two sets of lenses in this time) or the current myopia and astigmatism degrees can be added to the first dioptric training area of the first training lens 100 (one set of lenses in this time).
For example: if a person to be trained has-3.0D myopia, he has two ways to use the first training lens 100:
the first method is as follows:
the first training lens 100 in the form of a power +1.5D, range +0.75D to +3.00D convex lens may be directly fitted over the first refractive training area 101.
The second method comprises the following steps:
the first dioptric training area 101 degrees of the first training lens 100 is made to be-3.0D + (+1.5D) — 1.5D, and the person to be trained only needs to wear one set of lenses. Both approaches achieve the desired objectives and effects.
With the first training lens 100 of the above-described structure, the hyperopic defocus phenomenon caused by the central and peripheral images closer to the eye and the focus of the central and peripheral images moving further backward is avoided, so that activation of the near reflex pathway center, contraction of ciliary muscle, expansion of the anterior and posterior diameters of the crystalline lens, and increase of accommodation can be avoided.
Please refer to fig. 2, which is a schematic structural diagram of a second training lens 200 for remote use according to the present invention.
The second training lens 200 for long-distance use is suitable for long-distance work, and is suitable for daily activities such as watching a blackboard at a distance, watching a movie, watching a distance, walking, indoor and outdoor, and the like.
The second training lens 200 has three designs, which are described below:
as shown in fig. 2(1), the second training lens 200 is also divided into a first dioptric training area 201 of the lens, a second dioptric training area 202 of the lens and a transition area 204 between the two areas.
The first refraction training area 201 is a round flat area with a diameter of 15mm (not limited to this, range 5-20 mm) or a hollowed area, the central power is 0, the second refraction training area 202 is a lens with a certain power, and the power adjustment of the second refraction training area 202 is based on the comfort of the person to be trained. The hyperopic defocus just beyond the macula edge is corrected to +0.5D and the peripheral hyperopic defocus of 45 deg. is +4.5D, so the average of the degrees of the second refractive training region 202 is taken as the starting point, i.e. +2.50D, ranging from +1.00D to + 4.00D. For a wearer with myopia plus astigmatism, the peripheral power is +2.50D, ranging from +2.00D to + 3.00D. The width of the lens 200 is about 25 to 60mm (not limited to this range), and the height thereof is about 25 to 40mm (not limited to this range). The transition zone 204 satisfies: width: 0-10 mm; the power range is such that the minimum power is equal to or greater than the power of the first dioptric training region 201 and the maximum power is equal to or less than the power of the second dioptric training region 202.
The first method is as follows:
for the person who is not wearing the glasses for myopia, the person directly wears the second training lens 200 with the central power of 0 and the second dioptric training area 202 with the power range from +1.00D to + 4.00D.
The second method comprises the following steps:
the person to be trained who has worn myopic lenses can either directly fit the lenses (this time, two sets of lenses) or add the current myopic and astigmatic power to the first dioptric training zone of the second training lens 200 (this time, one set of lenses).
For example, if the person to be trained has myopia of-3.0D, the second training lens 200 is made to have a first dioptric training area 201 with degrees of-3.0D, a second dioptric training area 202 with degrees of +2.50D, and a peripheral range of degrees of +1.00D to +4.00D, and the person to be trained only needs to wear one set of lenses.
The third method comprises the following steps:
in addition to the above example of fig. 2(1), the structure of fig. 2(2) may also be adopted:
the second training lens 200 is also divided into a first refractive training area 201 of the lens, a second refractive training area 202 of the lens, a third refractive training area 203, and a transition zone 204 between the first and second refractive training areas 201 and 202.
The third refractive training area 203 is drawn from the second refractive training area 202 and is located above the first refractive training area 201 in the lens.
The first refraction training area 201 is a circular plain area with a diameter of 15mm (not limited thereto, in the range of 5-20 mm) or a hollowed area, and the central degree is 0. The third refractive training area 203 has the same power as the first refractive training area 201, and the second refractive training area 202 is a lens having a power, and the peripheral power is +2.50D, ranging from +1.00D to + 4.00D. For a wearer with myopia plus astigmatism, the peripheral power is +2.50D, ranging from +2.00D to + 3.00D. The second training glasses lens 200 has a left-right width of about 25 to 60mm (not limited thereto), and an upper-lower height of about 25 to 40mm (not limited thereto). Width of the transition area 204: 0-10 mm; the power range is such that the minimum power is equal to or greater than the power of the first dioptric training region 201 and the maximum power is equal to or less than the power of the second dioptric training region 202.
For example, if a person to be trained has-3.0D myopia, he may use the second training lens 200 in FIG. 2(2) in two ways:
the first method is as follows: directly fitting a second training lens 200;
the second method comprises the following steps: the second training lens 200 is made into a first dioptric training area power and a third dioptric training area power which are both-3.0D, the peripheral power is +2.50D, the peripheral power range is +1.00D to +4.00D, and a trainee only needs to wear one set of lenses. Both approaches achieve the desired objectives and effects. The second refractive training area 202 other than the first refractive training area 201 and the third refractive training area 203 of the second training lens 200 is purple in a depth of 25% (not limited thereto, in a range of 10% to 50%). The reasons and benefits of selecting purple are: the non-glare effect is that the shortest wavelength in the visible light is about equal to the effect of adding +0.15D to the red light, so that the hyperopic defocus phenomenon of the peripheral retina can be simultaneously inhibited in the long-distance operation.
Wearing the second training lens 200 does not affect the central vision of looking away and watching tv, etc., and the wearer can also move about freely.
It should be noted that, in the above embodiments, the first refraction training areas 101 and 201 are both circular, and may be replaced by other closed shapes such as an oval, a square, a rectangle, and a polygon.
Fig. 3 shows a schematic structural diagram of a pair of training glasses 5 formed by applying the first training lens or the second training lens to a frame 51.
It should be noted that, for the person to be trained who does not wear glasses, the size and shape of the frame 5 are normal, and the person can directly wear the frame during training; for the person who is trained and wears the glasses with myopia or myopia and astigmatism, the spectacle frame 5 is slightly larger in size and is sleeved on the original spectacle frame of the person who is trained during use.
The special lens for counteracting the peripheral hyperopic defocus phenomenon is properly used for dealing with the scenes of near or far vision, and can be used by the trained person who does not wear or wears the myopia glasses, so that the peripheral retinal hyperopic defocus phenomenon can be continuously resisted, and the occurrence and the development of the pseudomyopia and the true myopia can be inhibited.
In order to enhance the training effect, the present invention further provides a training device in cooperation with the training glasses, and please refer to the following description.
Fig. 4(1) and 4(2) show a front view and a side view, respectively, of the training device 300 of the present invention, which will be described in detail in conjunction with the two figures.
The present training device comprises a base 308, a stand 309 and a vertical training screen unit 301. The base 308 is typically a non-slip structure that functions to support the bracket 309 and the training screen unit 301.
The training screen unit 301 is a rectangular plate and is divided into three areas longitudinally, which are a screen first area 305, a screen isolation area 306 and a screen second area 307.
The bracket 309 is vertically disposed relative to the base 308 and is located right in front of the center of the training screen unit 301. In order to adapt to the height and face shape difference of the person to be trained, an adjustable head support 302 and an adjustable chin support 303 are further arranged on the support 309.
In addition, the apparatus further includes a distance adjustment unit 304 for adjusting the width of the screen isolation area 306, or the horizontal spacing of the first and second screen areas 305 and 307, which is generally disposed above the training screen unit 301 for convenient operation.
The above-described training screen unit 301 is made of a lightweight, sturdy material in which the screen isolation region 306 is opaque carbon black, the right screen first region 305 is red transparent (but not limited to red), and the left screen second region 307 is green transparent (not limited to green), so that the opaque carbon black screen isolation region 306 divides the screen into left and right views, while avoiding the action of binocular cohesive viewing that would cause near-reflective pathways.
In a preferred embodiment, the first region 305 of the red transparent screen has a width of 7-15 cm, a height of 25-30 cm and a thickness of 0.2-0.5 cm.
The width of the second area 307 of the green transparent screen is 7-15 cm, the height is 25-30 cm, and the thickness is 0.2-0.5 cm.
The opaque carbon black screen isolation region 306 has a height of 25-30 cm and a thickness of 0.2-0.5 cm, and is adjusted to a uniform width according to the first eye pupil distance of an observer.
Fig. 5(1) and 5(2) are schematic diagrams further illustrating the distance adjusting unit 304 and the adjustment of the screen isolation area 306.
The screen isolation region 306 is composed of a front plate unit 3061 and a rear plate unit 3062 which are superposed, the upper edges of the two units are provided with scales, the maximum length of the front plate unit 3061 is 45mm, and the maximum length of the rear plate unit 3062 superposed behind the front plate unit 3061 is 25 mm. The rear plate unit 3062 may be pulled out with the pulling of the distance adjusting unit 304 in the arrow direction, gradually increasing the width of the screen isolation region 306 from 45mm of the front plate unit 3061 to the maximum, thereby adjusting the width of the screen isolation region 306 by the pulling of the distance adjusting unit 304.
The width may vary from the starting position shown in fig. 5(1) to 45mm until the rear plate unit 3062 is fully pulled out to a maximum width of 70 mm. This design aims at adjusting the width of screen isolation region 306 according to the first eye pupil distance of the observer when using the present training device.
Referring to fig. 6, there is shown an exemplary diagram of training glasses, training device and training system using the training glasses and training device of the present invention.
The person to be trained sits on the table and wears the first training lens 100 used at a short distance, the training device 300 and the display unit 400 are placed on the table top facing the person to be trained in sequence, the distance between the training device 300 and the display unit 400 is not less than 45cm, and the training device 300 is arranged between the person to be trained and the display unit 400.
Before training, the interpupillary distance width of the person to be trained is first measured. Based on the width, the relative positions of the front and rear plate units 3061 and 3062 of the screen isolation region 306 are slidably adjusted so that the width of the screen isolation region 306 is equal to the pupil distance width.
The chin and head of the person to be trained are tightened and fixed to the adjustable chin rest 303 and the adjustable head rest 302 of the training apparatus 300.
The present invention adopts a method of binocular training, so that by dividing the training screen unit 301 into three areas, the central visual field area of both eyes is divided into a screen first area 305 and a screen second area 307 which are relatively independent of each other for one eye because the screen isolation area 306 in the middle is carbon black. Thus, the right eye sees the red first central training optotype 4011 and the green second central training optotype 4012 through the red transparent screen first region 305, and the left eye sees the red first central training optotype 4011 and the green second central training optotype 4012 through the green transparent screen second region 307.
The peripheral retina is insensitive to color because of the lack of cone photoreceptor cells, and is trained using black peripheral optotypes, at which time the black effect is seen or is unchanged when the eye views the black peripheral optotypes on the same side or opposite side through a red or green transparent screen.
The utility model adopts two training visual targets to play different roles.
Wherein, when the central training sighting mark makes the left and right eyes generate reverse fusion, the two eyes are locked at a fixed position, thus avoiding influencing the training effect due to the movement of the eyes when training the peripheral vision field.
The consideration factors of using the black peripheral training optotypes are as follows: the red filter is in front of the right eye, the green filter is in front of the left eye, and at this time, the east and west of whatever color is used can generate the condition that one eye has stronger acceptance, the other eye has lower acceptance, and the two eyes obtain different things. In addition, the peripheral retina has a very small number of photoreceptor cells which are very color-responsive, and mainly senses the contrast between black and white and the contrast between brightness, so that the peripheral training optotype with other colors has little or no meaning. Therefore, the applicant selects a black peripheral training optotype (e.g., black horse), and the optotype is black regardless of the color of red, green or other colors, so that the observer does not have a binocular disparity and a disordered feeling is not generated.
In the above embodiment, the right red screen first region 305 and the left green screen second region 307 may be reversed, i.e., the screen first region 305 is green and the screen second region 307 is red. However, it is necessary to ensure that the first central training optotypes corresponding to the first zone are consistent in color and the second central training optotypes corresponding to the second zone are consistent in color.
The training optotypes of the display unit 400 are further described below.
In the training process, the display unit 400 provides the visual targets used by two single eyes at the same time, the distance between the two visual targets is not less than the distance of the pupils of the first eye, the visual processing center of the brain senses the visual targets respectively collected by the two single eyes, and then the two visual targets are fused together to obtain the binocular single vision effect, so that the activation of the near reflex pathway center can be inhibited, the ciliary muscle is relaxed from the contraction and spasm state, the front and back diameters of the crystalline lens are recovered to be normal from the enlargement state, the abduction extraocular muscle is strengthened and the cohesion extraocular muscle is weakened.
Fig. 8 shows that different central training optotypes 4041 and 4042 are seen by the left and right eyes, and the effect of single vision of both eyes is obtained after the brain vision center is reversely fused, that is, two central training optotypes are combined into a fused image 4013 to achieve the effect of locking two eyeballs, and then the training of the peripheral optotypes can be started. Fig. 9 is a schematic diagram showing a positional relationship between the central training optotypes 4011 and 4012 and the peripheral training optotypes 4021 and 4022 on the display unit 400.
The display unit 400 has a display space 403 in the center, the width of the display space 403 is the same as the width of the screen separation area 306 on the training device 300, when the person is sitting and training, the display space 403 of the display unit 400 is just behind the screen separation area 306 of the training device 300, i.e. the right and left eye sight of the person is just separated by the display space 403 and the two sides of the screen separation area 306.
Fig. 10(a) to 10(g) show schematic diagrams of the training process of the central training optotype on the display unit 400.
The states of the first and second peripheral training optotypes 4021 and 4022 include both static and dynamic states.
When the first and second central training optotypes 4011 and 4012 are at the initial positions of the first eye position pupil distance plus 2-30 mm and the person to be trained is in a non-moving binocular single vision state, the first and second peripheral training optotypes 4021 and 4022 are used as necessary conditions for training. Next, the action process of the two peripheral training optotypes 4021 and 4022 is described in detail as follows:
fig. 10(a) illustrates a static mode of the first and second peripheral training targets 4021 and 4022, i.e., both training targets are in a starting position, stationary. Position 25 ° on the temporal side of the visual field;
fig. 10(b) to 10(g) illustrate the dynamic modes of the lower two peripheral training optotypes 4021 and 4022 indicated by arrows, specifically:
fig. 10(b) shows a case where the first peripheral training visual target 4021 moves in the direction of the second peripheral training visual target 4022, as indicated by a right arrow;
fig. 10(c) shows the first peripheral training visual target 4021 being closer to the second training visual target 4022;
FIG. 10(d) is a schematic diagram of the complete overlap of two peripheral training optotypes 4021, 4022;
then, as indicated by the arrow, the first peripheral training visual target 4021 moves in the opposite direction away from the second peripheral training visual target 4022, returning to the starting position, as shown in fig. 10(e) to 10 (g).
The training steps are repeated at least twice.
In the above embodiment, the example pattern used by the peripheral training optotypes is a cartoon pattern of a galloping horse, and other patterns may be selected.
The length range of the first and second central training sighting marks 4011 and 4012 is 5 mm-60 mm, and the aspect ratio or width-to-length ratio is 1: 5, or more.
The moving speed of the central training sighting marks 4011 and 4012 is 0.1-3 DEG/second.
The first and second central training optotypes 4011 and 4012 include any one of a 3D optotype, a pattern optotype, a character optotype, a pattern and character combination optotype, and a pattern and color combination optotype.
The backgrounds of the first and second central training optotypes 4011 and 4012 are gray, and usually comprise two backgrounds, which are respectively displayed on the screens corresponding to the visual fields of the left and right eyes, and the colors of the optotypes of the left and right eyes are different but must be consistent with the colors of the corresponding first and second areas of the transparent screen. For example: the right eye sees the red central training optotype through the area of the red transparent screen, and the left eye sees the green central training optotype through the area of the green transparent screen; the right eye sees the blue central training optotype through the area of the blue transparent screen, and the left eye sees the yellow central training optotype through the area of the yellow transparent screen.

(1) background color of peripheral training optotypes: grayish.
(2) Color of peripheral training optotypes: matte black patterns, such as: cartoon of horse.
(3) Position of peripheral training optotype: on the temporal side of the visual field at a position of 25 to 60 degrees.

(6) The peripheral training optotypes can be independently appeared on the left or right temporal side visual field for training, and the side is not limited during unilateral training each time.
The utility model can be realized by a complete set of application software. The software can be installed on a computer, a mobile phone or a tablet personal computer, a trainee can freely select required training contents through direct operation on the interaction ends, training is carried out by watching training sighting marks on a computer screen, a television screen or a projection screen, and the sighting marks, background music and the like can be changed according to actual requirements in the training process.
The application program has two versions of an online APP and an offline APP.
