Description
Technical Field
The invention relates to the technical field of eye disease treatment equipment, in particular to a lens for improving peripheral vision and assisting in improving vision and an application method of the lens for improving peripheral vision and assisting in improving vision.
Background
Myopia, which is a problem of blurred distance vision caused by focusing of a distant target image in front of the retina, is a global visual problem, and occurs in all people of all ages and all nationalities.
Research has proved that the progressive increase of myopia degree is related to the following factors: 1. when the far-looking glasses see close, the central visual field object image falls behind the retina to gradually lengthen the length of the central area ocular axis, which is closely related; 2. even if the far-looking glasses are used for far-looking, the object image of the central visual field is fallen on the retina, and the object image of the peripheral visual field of the posterior segment of the eyeball is fallen behind the retina due to the spherical shape of the eyeball, so that the axial length of the peripheral visual field is gradually lengthened; 3. because modern people rarely use peripheral vision near the equator, the self-repairing process of using peripheral vision by wild animals and using large-angle peripheral vision stimulation to make object image fall outside the equator of retina is lost, and in order to clearly see the object image, the brain and eyeball can expand the diameter of equator of eyeball and shorten the length of front and back of axis of eye by regulating eyeball.
Traditional vision solutions have focused on controlling central vision with the goal of providing good central vision. However, although the conventional single vision lens can correct central vision and has negative effect on peripheral vision, the principle is shown in detail in fig. 1 and 2. FIG. 1 shows that after correction, the periretinal portion of the myopic group exhibits relative hyperopic defocus in the horizontal direction; the peripheral part of retina of the hyperopia group shows relative myopic defocus in the horizontal direction. Fig. 2 shows that the periphery of retina of the myopia population is absolute hyperopic defocus when wearing glasses, and the hyperopic defocus ratio is more obvious when wearing glasses than when not wearing glasses in the moderate myopia population.
For myopia, its periphery is projected behind the retina. This causes the retina to elongate backwards, accelerating the rate at which the axis of the eye lengthens. For hyperopia, its periphery is projected in front of the retina. This prevents the sclera and retina from growing normally.
The related patent technology comprises the following steps:
the application numbers are: 200710128970.X, the invention name is: can be used for treating and assisting in treating eye diseases such as myopia.
The application is based on the common visual window area, and is added with visual training device and detachable massage device for treating and assisting in treating asthenopia, myopia, hypermetropia, amblyopia and presbyopia. The common window area of the glasses is arranged in the center area of the visual field of the glasses, and the length of the axis of the eyes is gradually guided to be normal through defocusing of each glasses in the emmetropic direction in the degree decreasing glasses group. In the degree decreasing glasses group: the degressive glasses group consists of one, a plurality of or even dozens of glasses, or consists of glasses with replaceable lenses and a plurality of or even dozens of glasses.
In the above patent, "the degressive glasses group is composed of one, several, or even tens of glasses", which is relatively complex in structure and high in cost, and is difficult to implement, popularize and apply.
The method is natural:
xuguangdi old mr, given on page 57 of ophthalmology refractometry, almost all birds and beasts on land are not near sighted.
The present investigators believe that this can be done by wild animals for two reasons:
① the wild animal needs frequent vision around eyes to defend natural enemies, the process can promote blood circulation, remove blood stasis and improve eyeball blood circulation, the eyeball has good blood circulation, no asthenopia, no pseudomyopia, no true myopia, and myopia can be prevented and treated.
② the peripheral visual field of wild animals is well utilized, the peripheral visual field is irradiated to the outside of retina of the equator part through the pupil, the diameter of the equator of the eyeball must be enlarged to clearly see the peripheral visual field, and the length of the front and back of the axis of the eye is shortened.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The invention provides a lens for improving vision by peripheral vision and assisting in improving vision, which consists of three areas: a central lens field, a near lens peripheral field, and an equatorial lens peripheral field.
The invention is used for improving and assisting in improving the eyesight of asthenopia, myopia, hypermetropia, astigmatism, amblyopia and presbyopia. Wherein,
the lens central visual field area is arranged in the lens visual field central area, and the length of the eye axis is gradually guided to be normal through slight defocusing of an object image in the lens central visual field area in the front view direction.
The near peripheral visual field area of the lens is arranged between the central visual field area and the equatorial peripheral visual field area of the lens, the object image is positioned at the periphery of the back section of an eyeball, the object image at the peripheral visual field area near the lens is defocused in the emmetropic direction, a force that the peripheral visual field tends to emmetropic is formed, and the length of the induced eye axis tends to be normal.
The lens equatorial peripheral vision zone is arranged in the peripheral outermost region of the visual field, the object image is located in the vicinity of the eyeball equator and defocuses in the opposite direction with respect to the lens central vision zone and the lens near peripheral vision zone: 1. the power for enlarging the diameter of the equator of the eyeball is formed for myopia; 2. the force for reducing the diameter of the equator is formed for far vision, and the force for forming emmetropization in the central visual field area and the near peripheral visual field area is further assisted, so that the axial length of the eye is gradually induced to be normal.
The Fresnel lens mainly comprises a convex lens, a concave lens, a meniscus lens, a Fresnel mirror and/or a Fresnel film.
The following are defined herein: the optical centers of the lens central visual field area, the lens near peripheral visual field area and the lens equator peripheral visual field area are superposed;
lens central field of view: the degree of slight defocusing in the front view direction is 0-200 degrees, more preferably 25-100 degrees, and most preferably 50-75 degrees, so that the object image can fall in the range of 0.00-0.66 mm inside the retina in the central visual field area.
For the eyeball of a myopic user:
the power difference between the near peripheral visual field area and the central visual field area of the lens can be selected from +100 to +2000 degrees, more preferably from +200 to +1500 degrees, and most preferably from +300 to +1000 degrees, so that the object image can be positioned at the inner side of retina of the near peripheral visual field area by 0.1 to 3 mm.
The diopter range of the lens equatorial peripheral vision zone is: 0 to the degree of the central visual field area of the lens, so that the object image can fall 0.1 to 3mm outside the retina of the peripheral visual field area of the equator. Based on the structure design, the diameter of the equator of the eyeball is enlarged by a user in order to clearly see the object image brain and the eyeball, and the length of the axis of the eye in the central visual field area and the near peripheral visual field area can be gradually shortened to be in the orthographic view.
For the eyeball of a hyperopic user:
the degree difference formed by the near peripheral visual field area and the central visual field area of the lens is-25 to-1000 degrees, more preferably-50 to-800 degrees, and most preferably-100 to-600 degrees; thus, the object image can be located 0.1-3 mm outside the retina in the near peripheral visual field area, and the length of the eye axis in the near peripheral visual field area gradually tends to the emmetropization direction.
The degree difference formed between the peripheral visual field area and the central visual field area of the lens equator can be selected from +300 to +2500 degrees; more preferably +800 to +2000 degrees. Thus, the object image can fall on the inner side of the retina of the equator by 0.1-3 mm, and the length of the axis of the eye in the central visual field area and the near peripheral visual field area can be gradually prolonged and tends to be emmetropic due to the reduction of the diameter of the equator of the eyeball.
The absolute value of the corresponding power of the near peripheral visual field area and the near central visual field area of the lens is smaller than that of the corresponding power of the near equatorial visual field area of the lens, the power of the whole near peripheral visual field area is gradually changed, and the image type of the quadratic function is enlarged from inside to outside.
In one embodiment of the invention, the distance between the eyes is calculated as 12 mm: the diameter range of the central vision field of the lens is 8-28 mm; the diameter range of the visual field area near the periphery of the lens is 10-48 mm; the diameter range of the peripheral vision area of the equator of the lens is 40-60 mm.
The power profiles for the lens central, near lens peripheral and equatorial lens peripheral vision zones are as follows:
1. the method is realized by setting different powers in different areas of a convex lens, a concave lens, a meniscus lens, a Fresnel lens and/or a Fresnel film;
2. on the basis of a normal correcting lens, the correction is realized by bonding a convex lens, a concave lens, a Fresnel lens or a Fresnel film in a peripheral visual field area near the lens and a peripheral visual field area at the equator of the lens;
3. on the basis that a near peripheral visual field area of the lens, a peripheral visual field area of the equator of the lens are Fresnel lenses and a central visual field area of the lens is a flat lens, the adjustment of the spectacle power of the central area is completed by bonding convex lenses and concave lenses with different powers at the flat lens of the central visual field area;

The lens equator peripheral visual field area 1 is arranged in the peripheral outermost area of the visual field, the object image is positioned at the position near the equator of the eyeball and defocuses reversely through the lens central visual field area 3 and the lens near distance peripheral visual field area 2; wherein, the object image of the near equator peripheral visual field area 1 is set to fall on the outer side of retina to form a force for enlarging the diameter of the equator of the eyeball, and the volume of the eyeball is a certain amount and can smoothly shorten the length of the axis of the eye only by enlarging the diameter of the equator; for the object image of the visual field area 1 around the equator of the hyperopic lens, the object image is set to fall on the inner side of the retina to form a force for reducing the diameter of the equator, and similarly, the development of the axial length of the eye to the emmetropic direction can be smoothly promoted only by reducing the diameter of the equator; thereby helping the central visual field area and the near-distance peripheral visual field area to form the orthographic vision force and gradually inducing the length of the eye axis to be normal;
the eyeball of a user with myopia is shown in fig. 3 and 4.
The degree difference formed between the near peripheral visual field area 2 of the lens and the central visual field area 3 of the lens is selected from +100 to +2000 ℃; more preferably +200 to +1500 degrees; the most preferred is +300 to +1000 ℃; the object image is located 0.1-3 mm inside the retina in the near peripheral visual field area.
The diopter of the lens in the peripheral visual field area 1 at the equator is selected to be 0-the diopter of the lens in the central visual field area, so that the object image falls on the outer side of the retina in the peripheral visual field area at the equator by 0.1-3 mm; in order to make clear the brain and eyeball of the object image, the diameter of the equator of the eyeball is enlarged, and the power for shortening the axis of the eye is formed.
The eyeball for a hyperopic user is shown in fig. 5 and 6.
The degree difference formed by the near peripheral visual field area and the central visual field area of the lens is-25 to-1000 degrees, more preferably-50 to-800 degrees, and most preferably-100 to-600 degrees; thus, the object image can be located 0.1-3 mm outside the retina in the near peripheral visual field area, and the length of the eye axis in the near peripheral visual field area gradually tends to the emmetropization direction.
The degree difference formed between the peripheral visual field area and the central visual field area of the lens equator can be selected from +300 to +2500 degrees; more preferably +800 to +2000 degrees. Thus, the object image can fall on the inner side of the retina of the equator by 0.1-3 mm, and the length of the axis of the eye in the central visual field area and the near peripheral visual field area can be gradually prolonged and tends to be emmetropic due to the reduction of the diameter of the equator of the eyeball.
