Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1-5, in a first aspect, the embodiment of the present application provides an asymmetric defocusing lens, which includes a lens body 1, a plurality of microlenses 2 distributed in an annular shape are disposed on a light-entering side of the lens body 1, and the plurality of microlenses 2 together form an defocusing area 3; the out-of-focus zone 3 includes a distance zone 31, a near zone 32, a nasal zone 33, and a temporal zone 34; the far vision area 31 is distributed above the center of the light inlet surface 11 of the lens body 1, the near vision area 32 is distributed below the center of the light inlet surface 11 of the lens body 1, the nose area 33 is distributed on one side of the light inlet surface 11 of the lens body 1 close to the nose, and the temporal area 34 is distributed on one side of the light inlet surface 11 of the lens body 1 far away from the nose.
Based on the above technical solution, in the asymmetric defocus lens, a plurality of annularly distributed microlenses 2 are arranged on a light-entering side surface of the lens body 1, and each microlens 2 can change the refraction direction of light, so that the microlenses 2 together form an out-of-focus area 3, and parallel light rays which are about to enter the eye lens 52 can be focused in front of the retina 51, so that the light rays are discrete when reaching the retina 51 and cannot form an image on the retina 51 or behind the retina 51, thereby realizing the purpose of inhibiting the excessive increase of the eye axis 54 to correct myopia.
Generally, the eyeball is not a spherical structure but an asymmetric ellipsoidal structure, the horizontal-path refractive power and the vertical-path refractive power of the lens 52 to the incident light are different, and the asymmetric defocusing lens sets different defocusing amounts in all directions of the defocusing area 3 in order to be matched with the lens 52 and ensure that all directions of discrete light falling on the retina 51 are inconsistent. The out-of-focus area 3 comprises a far-vision area 31, a near-vision area 32, a nose side area 33 and a temporal side area 34, wherein the far-vision area 31 is distributed above the center of the light inlet surface 11 of the lens body 1, the near-vision area 32 is distributed below the center of the light inlet surface 11 of the lens body 1, the nose side area 33 is distributed on one side, close to the nose, of the light inlet surface 11 of the lens body 1, and the temporal side area 34 is distributed on one side, far away from the nose, of the light inlet surface 11 of the lens body 1.
It should be noted here that after the light reflected by the object is defocused by the asymmetric defocusing lens, the light is focused in front of the retina 51, and the light is discrete when reaching the retina 51 and cannot be imaged on the retina 51 or behind the retina 51, so that when a person looks at the object, the eye automatically adjusts and drives the eye axis 54 to shorten so that the retina 51 moves forward (the eye axis 54 is the distance from the cornea 53 to the crystalline lens 52 to the vitreous body to the retina 51, the eye axis 54 shortens, the retina 51 is closer to the cornea 53, and can be understood as the retina 51 moves forward), so that the eye axis 54 can be restrained from excessively increasing, and the eye axis 54 can also be shortened so as to correct myopia.
In some embodiments, the micro-lens 2 has a bottom surface 21 connected to the light inlet surface 11 of the lens body 1 and a circular arc surface 22 protruding from the light inlet surface 11 of the lens body 1; the inner diameter r1 of the bottom surface 21 is 800-1200 μm; the height h of the micro lens 2 protruding from the light inlet surface 11 of the lens body 1 is 0.5-1.5 μm; the radius r2 of the circular arc surface 22 is 1.5 x 10 ^ 5 μm-2.5 x 10 ^ 5 μm.
Parallel light rays are refracted when entering the arc surface 22 of the micro lens 2, then pass through the micro lens 2 and the lens body 1 in sequence, and exit from the light-exiting surface 12 on the light-exiting side of the lens body 1, when entering the lens 52, the incident angle of the light rays is changed apparently, and the light rays are refracted by the lens 52 and then focused in front of the retina 51, so that the light rays are discrete when reaching the retina 51, cannot be imaged on the retina 51 or behind the retina 51, and cannot drive the ocular axis 54 to be over expanded backwards, for teenagers, the ocular axis 54 is a key period of development, and the asymmetric defocused lens can inhibit the ocular axis 54 from being over expanded backwards, so that the teenager myopia can be corrected.
In the present application, the bottom surface 21 has an inner diameter r1 of 800 μm to 1200 μm; the height h of the micro lens 2 protruding from the light inlet surface 11 of the lens body 1 is 0.5-1.5 μm; the radius r2 of the circular arc surface 22 is 1.5 x 10 ^ 5 μm-2.5 x 10 ^ 5 μm, so that the defocus amount of the microlenses 2 is between +2.5D and +3.0D, or higher than +3.0D, and therefore, the present application can set the defocus amount of the defocus area 3 accordingly according to the degree of myopia of the patient. Generally, the defocus amounts of the far vision zone 31, near vision zone 32, nasal side zone 33, and temporal side zone 34 of the present application may each be set to +2.5D to +3.0D to fit the near vision power of most patients; the present application can also set the defocus amount of the far vision zone 31, the near vision zone 32, the nose side zone 33 or the temporal side zone 34 to +6.0D according to the myopia degree of a small part of patients, for example, when the myopia degree of a teenager patient is 600 °.
Generally, based on a structure specific to an eyeball, a fundus approximates a sphere, and a position of a macula of the retina 51 belongs to an imaging region, whereby a distance to an anterior apex of a cornea 53 toward a periphery is gradually changed; therefore, in the present application, the microlenses 2 are distributed in a plurality of rows and circular rings from the center to the outside around the center of the light inlet surface 11 of the lens body 1. Based on the movement track of the eyeball sight, the track rotates from the central orthographic state to the periphery, therefore, the micro lenses 2 are diffused from the center of the lens body 1 to the periphery, so as to ensure that the complete defocusing effect can be achieved in the effective visual field area of the glasses.
Further, the distance b1 between two adjacent rows of microlenses 2 is 1.5 times to 2.5 times the inner diameter r1 of the bottom surface 21; the distance b2 between two adjacent microlenses 2 in a row of microlenses 2 is 1.5 times to 2.5 times the inner diameter r1 of the bottom surface 21, so that interference between two adjacent microlenses 2 can be prevented, and discrete light rays are mutually interwoven to influence the defocusing effect.
In this application, lens body 1 has orthophoria 4, and orthophoria 4 distributes in the center department of focus area 3, and orthophoria 4 is used for correcting eyesight, and the light through orthophoria 4 can be clear formation of image on retina 51 to make the patient can see clearly, so that the patient can carry out daily activity.
In the application, the normal vision zone 4 is distributed at the center of the out-of-focus zone 3, based on the object viewing habit of human eyes, in daily life, people are used to look at objects normally, namely, light reflected by the objects is directly projected into the crystalline lens 52, and is focused and imaged on the retina 51 after being refracted by the crystalline lens 52; therefore, when the patient wears the lens, the front vision area 4 can meet the requirement that the light reflected by the object directly enters the crystalline lens 52, so that people can clearly see objects, and the defocusing area 3 can enable the light obliquely entering the crystalline lens 52 to be defocused so as to correct myopia.
Here, to correct vision, it means that light rays can be clearly imaged on the retina 51 of a patient through refraction of the lens, and when the lens is removed, the patient still cannot see objects clearly; myopia is corrected by focusing parallel rays of light that are about to enter the lens 52 of the eye in front of the retina 51 so that the rays are discrete when they reach the retina 51 and cannot be imaged on the retina 51 or behind the retina 51 to inhibit the expansion of the eye axis 54, and simultaneously, the eye axis 54 is driven to shorten so that out-of-focus rays of light can be focused on the retina 51 to correct myopia, and the myopic eye of the patient can be cured later without wearing glasses and also can be clear.
The method can reasonably divide the light zone of the defocusing zone 3 according to the visual field of human eyes, and the far vision zone 31 is a fan-shaped zone alpha 1 with the horizontal radial line 41 of the front vision zone 4 in the anticlockwise direction of 30-150 degrees; the temporal area 34 is a sector area alpha 4 of the horizontal radial line 41 of the frontal area 4 in the counterclockwise direction of 150-225 degrees; the near vision zone 32 is a sector area alpha 2 of the horizontal radial line 41 of the front vision zone 4 along the counter-clockwise direction of 225-315 degrees; the nose area 33 is a sector area alpha 3 of a horizontal radial line 41 of the front view area 4 from 30 degrees in the counterclockwise direction to 45 degrees in the clockwise direction; wherein, the horizontal radial line 41 of the front viewing zone 4 passes through the center of the light inlet surface 11 of the lens body 1.
Generally, when the eye is near, the eyeball will generate two motions of pronation and pronation, therefore, the out-of-focus area 3 is divided into a far vision area 31, a temporal area 34, a near vision area 32 and a nasal area 33, so that the out-of-focus area 3 can generate inconsistent defocus amounts in various directions, thus, the defocus effect can be more effectively achieved, the asthenopia caused by over-adjustment can not be generated, the increase of the eye axis 54 can be effectively inhibited, and the myopia can be corrected.
In some embodiments, the microlens 2 and the lens body 1 are integrally formed, or the microlens 2 is arranged on the lens body 1 by pressing, and can adopt an injection molding mode to directly injection mold the asymmetric defocused lens, so as to shorten the construction period, and can also adopt a pressing mode to press the microlens 2 on the lens body 1, and when the pressing mode is adopted, the microlens 2 can be simultaneously processed with the lens body 1, so that the construction period can also be shortened.
In the present application, the lens body 1 includes a PC lens, also called space film or space film, and has the advantages of strong impact resistance, light weight, etc.
In the application, the micro lens 2 is made of PMMA, PET or PC, PMMA, the Chinese name is polymethyl methacrylate, and the micro lens has the advantages of high transparency, low price, easy machining and the like; PET, the Chinese name is polyethylene terephthalate resin, the characteristics are: the material is hard, strong in rigidity, high in strength, tough and small in friction coefficient; PC, the name polycarbonate, is a tough thermoplastic resin. PMMA, PET and PC are used for the microlens 2, so that the refraction of light can be realized, and the structural stability of the microlens 2 can be ensured.
As illustrated in fig. 5, in a second aspect, the present application also proposes an eyeglass comprising a frame and at least one asymmetric out-of-focus lens according to the first aspect; the asymmetric out-of-focus lens is arranged on the mirror frame.
The glasses of this application include picture frame and at least one foretell asymmetric out of focus lens, and the picture frame can be fixed in the unsettled preceding in patient's eyes with asymmetric out of focus lens to guarantee that this asymmetric out of focus lens can carry out of focus to the light steadily.
