The embodiment of the application solves the problem that the crowd adaptation range of the existing myopia prevention and control lens is limited greatly by providing the optical lens.
The technical scheme in the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:
The myopia prevention and control lens is a special lens aiming at slowing down the development of myopia, and the lens focuses peripheral light in front of retina through special optical design such as peripheral defocus design to form a myopia defocus signal to stimulate the eye regulation function so as to inhibit the increase of the eye axis and realize the purpose of preventing and controlling myopia. Common types of myopia prevention and control lenses include defocus lenses, progressive addition lenses and point spread technology lenses. The progressive multi-focus lens can meet the requirements of objects at different distances through a plurality of focus areas on one lens, so as to further relieve the visual fatigue. However, due to the fact that the distribution characteristics of fundus oculi vision function cells of different people are different, the sensitivity of different people to various types of optical signal stimulus is different, the existing myopia prevention and control lens is generally only suitable for a small part of specific people, and the universality of the myopia prevention and control lens is insufficient.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
An optical lens according to an embodiment of the present application will be described first.
Referring to fig. 1-6, an optical lens provided in an embodiment of the application includes a lens body 1 and an optical module, wherein a side portion of the lens body 1 includes a convex surface a and a concave surface B opposite to each other, the optical module includes at least two of a first optical element 2, a second optical element 3 and a third optical element 4 connected to the side portion of the lens body 1, and a distribution characteristic corresponds to a distribution of fundus oculi vision function cells of a lens wearer to provide multiple optical signal stimuli.
Specifically, the first optical element 2 is an optical element with scattering effect, the second optical element 3 is a multi-point defocused optical element, the third optical element 4 is in a continuous cylindrical lens structure, and any one of the first optical element 2, the second optical element 3 and the third optical element 4 has a preset mapping relation with the defocusing amount of the microstructure thereof relative to the arrangement position of the lens body 1.
In the embodiment of the present application, it can be understood that the present application provides a specific optical module on the basis of the lens body 1, the optical module covers at least two of the first optical element 2, the second optical element 3 and the third optical element 4, that is, the first optical element 2, the second optical element 3 and the third optical element 4 can be used in different combinations according to cost and requirements, the first optical element 2, the second optical element 3 and the third optical element 4 are divided into corresponding scattering effects, a multi-point defocus technology and a cylindrical lens structure, and the optical module of the present application integrates optical devices with different functions.
In particular, in a first aspect, the first optical element 2 is capable of providing contrast control of the light to the fundus based on scattering effects, it being understood that, first, scattering can uniformly distribute the light, which can be scattered in the ocular medium after it has entered the eye. The scattering phenomenon causes the originally concentrated light to diverge in all directions, so that the light is more uniformly distributed on the fundus. For example, when ambient light enters the eye through the pupil, a portion of the light is scattered by refractive media in the eye, such as the lens, vitreous, etc. The scattering effect is like scattering a beam of concentrated light, so that the light is not limited to a specific propagation direction, but can illuminate various areas of the fundus more widely, and the areas with strong contrast, which may exist originally, reduce the contrast due to the uniform distribution of the light, so that the illumination of the whole fundus is more uniform.
Second, the light received by the fundus includes direct light and scattered light, the scattered light and the direct light interact, and the direct light is the light directly emitted from the object and transmitted to the fundus along a straight line, and carries clear image information of the object, but may be affected by absorption, refraction and the like of an intraocular medium in the transmission process, so that the light intensity of a part of the area is weakened. The scattered light is light which reaches the fundus after being scattered by the intraocular medium, and although the scattered light cannot directly form a clear image, the scattered light can serve as background light to supplement and enhance contrast of an image formed by direct light. When the direct light forms a darker image, the scattered light can provide additional illumination, so that details of the image are easier to distinguish, and when the direct light is stronger, the scattered light can play a certain buffering role, so that the situation that the details are lost due to the fact that the image is too bright is avoided, and the fundus ray contrast ratio is adjusted.
Further, the degree of scattering of light of different wavelengths within the eye is different, which also helps to control the contrast of fundus light. Generally, shorter wavelength light is more prone to scatter, while longer wavelength light is scattered relatively less. This scattering property allows the light received by the fundus to have a certain spectral distribution during normal vision. For example, when the external light includes multiple wavelengths, the scattering of blue light can make the surrounding environment of the fundus obtain a certain degree of background illumination, and the light with the same wavelength as the red light can more effectively transmit the detailed information of the object. After the first optical piece 2 is arranged, through the comprehensive effect of scattering and direct irradiation of light rays with different wavelengths, the eyeground can form an image with proper contrast, so that the detail of an object can be seen clearly, and the object can be set off by certain background illumination, so that the visual effect is clearer and more comfortable.
In a second aspect, the second optical element 3 is capable of forming a plurality of defocus regions on the lens to effect control of the defocus state of the eye, and it is understood that light is focused on the retina to form a clear image when the normal eye is looking at an object. However, for myopes, the parallel rays are focused in front of the retina and imaging on the retina becomes blurred due to the excessive length of the eye axis or the excessive power of the refractive system of the cornea, lens, etc. Since the growth and development of the eye is closely related to the visual signals received by the retina, when the peripheral area of the retina is in a hyperopic defocus state, the eye axis is stimulated to further increase, resulting in the development of myopia. The second optical member 3 based on multi-point defocus forms near vision defocus in the peripheral area of the retina by a special optical design to suppress the increase of the eye axis and thereby control the development of near vision. Referring to fig. 2 and 4 together, the second optical element 3 is provided with a plurality of micro-second microstructures 31, and when light passes through the micro-second microstructures 31, the light is refracted and scattered to different degrees by the micro-second microstructures 31, so as to form a plurality of discrete myopic defocus regions on the retina. In addition, the degree of defocus control required by the eye at different gaze distances and angles is also different, and the second optic 3 has some dynamic defocus adjustment capability based on multi-point defocus control.
In the third aspect, the third optical element 4 can perform phase difference control based on the refractive characteristics of the cylindrical lens structure for light rays in different directions and the optimization effect for the spherical lens optical system, and it is understood that, first, astigmatism of eyes can cause light rays not to be focused on the same point, but form front and rear focal lines, so that phase difference is generated, and vision definition is affected. The cylinder has the ability to change the refraction of light in a specific direction, and when the axis of the cylinder corresponds to the astigmatism axis, the optical power can be increased or decreased in the direction, so that the light in different directions can be refocused on the retina, and the phase difference caused by astigmatism is reduced. Secondly, the cylindrical lens structure can adjust the whole refraction state of the eyeball by changing the propagation path of light, and then the phase difference is controlled. Finally, in addition to the phase differences caused by astigmatism and conventional refractive errors, there may be some higher order aberrations of the eye, such as coma, spherical aberration, etc., which may be compensated and corrected to some extent by the cylinder structure through special design and optimization.
Based on the above, the scattering effect, the defocusing control and the cylindrical lens structure have different directivities when in use, and the optical signal stimulus provided by the scattering effect, the defocusing control and the cylindrical lens structure have different effects on different people, and the optical lens can be used for combining at least two of the scattering effect, the defocusing control and the cylindrical lens structure, can correspond to fundus vision function cells of various people, adapt to different people, provide multiple optical signal stimulus for lens wearers on the premise of ensuring vision quality, and can still provide ideal myopia prevention and control effects when facing different specific people.
In some embodiments, the first optical element 2 is located at the concave surface B of the lens body 1 in case that the defocus amount of the microstructure of the first optical element 2 itself is positive, and the first optical element 2 is located at the convex surface a of the lens body 1 in case that the defocus amount of the microstructure of the first optical element 2 itself is negative.
In the embodiment of the present application, it is understood that the first optical member 2, the second optical member 3, and the third optical member 4 are arranged in a reasonable position with respect to the lens body based on the defocus amount of the own microstructure at the time of selection, and the mapping relationship between the arrangement positions of the second optical member 3 and the third optical member 4 with respect to the lens body 1 and the defocus amount of the own microstructure coincides with the first optical member 2. Namely, when different optical devices are arranged on the lens body 1, the lens is arranged on the concave surface B when the defocus amount of the microstructure of the optical device is positive, and is arranged on the convex surface A when the defocus amount of the microstructure of the optical device is negative.
It should be noted that, the defocus amount having a negative value means that light needs to be dispersed to achieve a specific optical effect, such as simulating myopia defocus to control myopia progression, etc. The convex surface a is more conducive to initial light divergence than if the negative defocus microstructure were located at the concave surface B or other locations. In addition, the negative defocus microstructure is arranged on the convex surface A, so that the propagation direction and angle of light rays can be better controlled, and aberration and distortion are reduced. When light is incident from the convex surface A and passes through the negative defocusing microstructure, the light can be converged or diverged more regularly, so that imaging is clearer and more accurate, and the problems of blurring, deformation and the like caused by irregular refraction of the light are avoided.
In some embodiments, referring to fig. 1-6, the lens body 1 is made of a polymer material including resin, and a part of the structure of any one of the first optical element 2, the second optical element 3 and the third optical element 4 is embedded in the lens body 1, and the other part of the structure protrudes out of the side of the lens body 1. It will be appreciated that the first, second and third optical elements 2,3 and 4 need to be embedded in the convex or concave surface a, B of the lens body 1 to be formed as a structurally stable whole, but that part of the structure of the first, second and third optical elements 2,3 and 4 need to protrude beyond the convex or concave surface a, B of the lens body 1 to adjust light propagation.
In some embodiments, referring to fig. 1-6, the optical module is composed of a first optical element 2, a second optical element 3 and a third optical element 4, and the first optical element 2, the second optical element 3 and the third optical element 4 are all arranged in multiple circles. At least two of the first 2, second 3 and third 4 optical elements on the same side of the lens body 1 partially overlap in the web of the lens body 1.
In the embodiment of the present application, it is understood that the first optical element 2 includes a plurality of first microstructures 21, the second optical element 3 includes a plurality of second microstructures 31, the third optical element 4 includes a plurality of third microstructures 41, and one third microstructure 41 corresponds to one cylinder structure, where diopters of the second microstructures 31 and the third microstructures 41 may be positive or negative.
It should be noted that, the first optical element 2, the second optical element 3, and the third optical element 4 are all reasonably selected according to the positive and negative conditions of the defocus amount of the first optical element 2, the second optical element 3, and the third optical element 4, when at least two of the first optical element 2, the second optical element 3, and the third optical element 4 are located on the same side of the lens body 1, the first microstructure 21, the second microstructure 31, and the third microstructure 41 are integrally formed with the lens body 1, and when the first microstructure 21, the second microstructure 31, and the third microstructure 41 are located on the same side of the lens body 1, the structures may be overlapped to superimpose different optical stimulus signals.
In one example, referring to fig. 4, the first microstructures 21 and the second microstructures 31 may be spherical, ellipsoidal, or polygonal, and it is understood that, since the human eye cells are polygonal, the first microstructures 21 and the second microstructures 31 may be polygonal to enhance the effect of the lens on the multiple optical signal superposition stimulation of the human eye cells.
In some embodiments, referring to fig. 1,3, 5 and 6, the lens body includes a central region C and a peripheral region D outside the central region C, and the first optical member 2, the second optical member 3 and the third optical member 4 are located in the peripheral region D, and the central region C corresponds to the macular region of the eye of the lens wearer. It will be appreciated that the peripheral region D and the central region C are contiguous with each other, and that the central region C is not provided with additional optics to ensure a clear view of the lens wearer, i.e. the first 2, second 3 and third 4 optical elements are all provided in the peripheral region D when provided.
In one example, the first optical element 2 and the second optical element 3 are both located on the convex surface a of the lens body 1 and the third optical element 4 is located on the concave surface B of the lens body 1. It will be appreciated that the lens structures shown in fig. 1 to 6 correspond to the case where the micro-structure defocus amount of the first optical member 2 and the second optical member 3 themselves is negative, and the third optical member 4 is positive.
In some embodiments, referring to fig. 1-4 together, the plurality of micro-structures in the first optical element 2 are distributed in an array, the first optical element 2 is adjacent to the central area C and has a radial width ranging from 3mm to 30mm, and the radial dimensions of the individual micro-structures in the first optical element 2 and the second optical element 3 are each ranging from 0.01mm to 0.4mm. The plurality of microstructure arrays in the second optical member 3 are distributed with a radial width ranging from 5mm to 45mm, and a part of the microstructures in the second optical member 3 and a part of the microstructures in the first optical member 2 overlap each other in space.
In the embodiment of the present application, it is understood that the microstructure in the first optical member 2 corresponds to the aforementioned first microstructure 21, and the microstructure in the second optical member 3 corresponds to the aforementioned second microstructure 31.
It should be noted that, the first optical element 2 based on the scattering effect is disposed adjacent to the central area C, and can form a scattering functional area near the central area C, so as to quickly compensate for the peripheral hyperopic defocus, when the eye is in different fixation states, especially when looking at near objects or performing eyeball rotation, the imaging condition of the peripheral visual field has an important influence on vision and eye health, and the scattering functional area is close to the central area C, so that the peripheral retinal hyperopic defocus can be compensated more quickly, because under these conditions, the peripheral retinal hyperopic defocus phenomenon is more likely to occur, and the scattering functional area can focus the peripheral light on the retina or in front of the retina more accurately by scattering light, thereby effectively reducing the peripheral hyperopic defocus, helping to control the increase of the eye axis, and having a positive effect on myopia prevention and control.
It should be noted that, the central area C is a key area for the eye to obtain clear visual information, and the scattering function area is disposed near the central area C, so that the scattering function area can be better cooperated with the visual function of the central area C. In daily vision activities, eyes frequently switch the fixation point between a central area C and a peripheral area D, and a scattering function area is closer to the central area C, so that light rays can be scattered more timely when different fixation points are switched, phenomena of blurring, ghosting and the like caused by inaccurate light ray focusing are reduced, the overall vision quality is improved, and a wearer can obtain clearer and comfortable vision experience in various vision scenes.
It is emphasized that the radial extent of the scattering-function region formed by the first optical element 2 is in the range of 3mm-30mm, the radial extent of the multi-point defocus-function region formed by the second optical element 3 is in the range of 5mm-45mm, i.e. the multi-point defocus-function region may be larger than the extent of the scattering-function region and may be located further from the central region C than the scattering-function region when arranged, in other words the scattering-function region is located closer to the central region C than the multi-point defocus-function region. This arrangement helps to create a smoother optical transition between the central region C and the multi-point defocus functional region, and the refraction and scattering changes of the light are more continuous and natural due to the fact that the scattering functional region has some buffering and tuning effect from the central region C to the peripheral multi-point defocus functional region. In contrast, if the scattering function region is far from the central region C, a significant optical difference may occur between the different function regions, affecting visual continuity, and the scattering function region is disposed near the central region C, which can be effectively avoided. Based on the above, the first optical piece 2 and the second optical piece 3 are reasonably arranged in the application, so that the vision conversion of eyes in different areas is smoother, and the visual fatigue and discomfort are reduced.
In some embodiments, referring to fig. 5 and fig. 6 together, the third optical element 4 includes a plurality of rings of microstructures, each ring of microstructures is arranged in a closed ring shape, the curvature of any position of each ring of microstructures along the circumferential direction is consistent, the radial width of the third optical element 4 ranges from 6mm to 60mm, and the width of each ring of microstructures ranges from 0.01mm to 0.4mm.
In the embodiment of the application, it can be understood that part of the population is sensitive to the third microstructure 41 which is continuous and annular, referring to fig. 4, and the other part of the population is sensitive to the first microstructure 21 and the second microstructure 31 which are discontinuous and lattice, and the optical module of the application can simultaneously comprise the first optical element 2, the second optical element 3 and the third optical element 4, and integrate the scattering effect, the multi-point defocusing technology and the cylindrical lens structure, thereby covering the eyeground vision function cell distribution rule of various populations, providing multiple optical signal stimulus in the high-density vision function cell area near the center of the light spot as much as possible, and improving the myopia prevention and control effect.
In summary, compared with the prior art, the application has the following beneficial effects:
1. The application is provided with a specific optical module on the basis of a lens body, the optical module can cover a first optical piece 2, a second optical piece 3 and a third optical piece 4, the first optical piece 2, the second optical piece 3 and the third optical piece 4 are divided into corresponding scattering effects, a multi-point defocusing technology and a cylindrical lens structure, when in use, the scattering effects, the defocusing control and the cylindrical lens structure have different directivities, the effects of optical signal stimulus provided by the three are different for different crowds, and the optical lens can be corresponding to the eyeground vision function cell distribution rules of various crowds by integrating different optical devices, adapt to different crowds and provide multiple optical signal stimulus for lens wearers.
2. The optical module integrates optical devices with different functions, the first optical piece 2 can provide contrast control for fundus rays, the second optical piece 3 can perform defocus control, the third optical piece 4 performs phase difference control, and the first optical piece 2, the second optical piece 3 and the third optical piece 4 are reasonably arranged relative to the lens body based on defocus amount of self microstructure during selection, so that the combination addition of the optical devices can achieve ideal effects.
3. According to the application, the first optical piece 2 and the second optical piece 3 are reasonably arranged, and compared with a multi-point defocus functional area formed by the second optical piece 3, a scattering functional area formed by the first optical piece 2 is closer to the central area C, so that smooth optical transition can be formed between the central area C and the multi-point defocus functional area, the scattering functional area plays a certain role in buffering and adjusting, and refraction and scattering changes of light rays are more continuous and natural from the central area C to the peripheral multi-point defocus functional area, so that visual transition of eyes in different areas is smoother, and visual fatigue and uncomfortable feeling are reduced.
The foregoing embodiments are merely for illustrating the technical solution of the present invention, but not for limiting the same, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that modifications may be made to the technical solution described in the foregoing embodiments or equivalents may be substituted for parts of the technical features thereof, and that such modifications or substitutions do not depart from the spirit and scope of the technical solution of the embodiments of the present invention in essence.
