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.

When the light imaging position deviates from the retina imaging area and the eyes cannot be adjusted in a self-adaptive manner, the eyes are stimulated by the deviating object image, the adjustment change trend with high intensity can be maintained, the eyes are subjected to large burden, and eye fatigue is easily caused. The light rays which are not imaged can not induce the backward adjustment of the eyes, thereby avoiding the deepening of the myopia degree

For a more particular understanding of the technical idea of the present application, exemplary embodiments are described below with reference to the accompanying drawings:

FIG. 1 is a schematic diagram of an implementable configuration of a myopic ophthalmic lens for protecting eye vision to which the present application relates; FIG. 2 is a schematic side sectional view of the embodiment of FIG. 1; FIG. 3 is a schematic diagram of the refraction path of light irradiated by parallel light after a myopic user wears the myopic spectacle lens for protecting the vision of the eyes provided by the application; fig. 4 shows the division of different areas of the corrective lens 1 for different physiological characteristics of each part of the eyeball. As shown in fig. 1-4: the application provides a myopia lens of protection eye vision, and correction lens 1 includes: a first refractive region that focuses light on the retina; and a second dioptric zone having a functional lens 2 (i.e. the zone covered by the functional lens 2 is the second dioptric zone), said functional lens 2 causing the light to form a discrete beam in front of the retina; the functional lens body 2 includes at least one annular lens, the at least one annular lens is disposed on the object-side surface of the corrective lens 1, and each annular lens protrudes toward the object-side direction.

The correcting lens 1 is a concave lens, before the light irradiates the eye, the correcting lens 1 diffuses the light, so that the light moves backwards at the convergence position of the eye of the wearer, the imaging position falls on the retina of the wearer, and a user with myopia can clearly see distant objects; the first dioptric zone exerts the characteristics of the corrective lens 1 itself, enabling the myopic user to see the distant objects clearly.

The parallel light rays are converged at one point by the convex lens, and the following conditions are required to be met: (1) all the light rays in the area have the tendency of deflecting towards a fixed point after being deflected by the convex lens; (2) the light rays passing through the same longitude line gradually increase in deflection angle from the center to the edge and finally converge at one point; (3) on the same latitude line, the deflection angles of all the parallel light rays are the same. As shown in fig. 3, the functional lens body 2 is an annular convex lens, the functional lens body 2 only converges incident light on the cross section thereof, so that light on the same cross section converges towards the center of the circle of the cross section, converges to the limit position and then diffuses to a distant place in a divergent manner, on the same functional lens body 2, parallel light incident on different cross sections do not converge together, that is, the light passing through the functional lens body 2 does not form an image on the retina, and the light not formed an image does not induce backward adjustment of the eye, thereby avoiding the deepening of the myopia degree.

As an optional embodiment of the present invention, the number of the functional lens bodies 2 is at least two, the functional lens bodies 2 are annular convex lenses, that is, the functional lens bodies 2 extend on an annular path, the extension radius of each functional lens body 2 increases uniformly, and the central axes of all the functional lens bodies 2 are overlapped with each other. A gap is arranged between two adjacent functional lens bodies 2, the center of the correcting lens 1 is taken as a diffusion center, and the first refraction area and the second refraction area alternately diffuse towards the edge of the lens.

The first dioptric area exerts the imaging characteristics of the corrective lens 1, and the wearer with myopia can see distant objects clearly; the second refraction area exerts the characteristic of no image formation per se, discrete light beams are provided at the retina, the discrete light beams are not imaged on the retina, the light rays which are not imaged cannot induce backward adjustment of eyes, and the myopia is prevented from being deepened. The user's eyes can automatically splice the object images formed by the two adjacent first refraction areas to form a complete picture. The center of the correcting lens 1 is taken as a diffusion center, the first refraction area and the second refraction area are diffused towards the edge of the lens alternately, and visual dead points cannot be caused by the existence of the second refraction area, namely, the imaging definition and the visual angle range cannot be influenced badly. Meanwhile, the first refraction areas and the second refraction areas are alternately arranged, so that the surface coverage rate of the second refraction areas on the correcting lenses 1 is large enough under the condition that the imaging function of the correcting lenses 1 is not affected, and the light rays passing through the second refraction areas are sufficient.

As an alternative embodiment of the invention, the width of the first dioptric region is not smaller than the width of the second dioptric region. The first refraction areas can enable a myopic eye user to see distant objects clearly, each first refraction area is an imaging unit, and the imaging units formed by the first refraction areas are overlapped with each other to form a clear and complete object image; and the light through the second refraction area does not form images, and the light which does not form images does not induce backward adjustment of eyes, so that the myopic degree is prevented from being deepened, the larger the surface coverage rate occupied by the second refraction area is, the stronger the light intensity of the non-imaging discrete light beams is, and because of the reason that the second refraction area does not form images, when the surface coverage rate of the second refraction area is too large, all the imaging units in the first refraction area can not be completely spliced into a complete picture, and the normal imaging function of the correcting lens 1 is influenced.

The functional lens bodies 2 are annular convex lenses, the number of the functional lens bodies 2 is multiple, the central axes of the functional lens bodies 2 are superposed with each other, and the central axis of each functional lens body 2 penetrates through the center of the correcting lens 1; a gap is arranged between two adjacent functional lens bodies 2, the region of the gap is a first dioptric region, the first dioptric region positioned at the most center is circular, and the first dioptric regions at other positions except the first dioptric region at the center are annular. The central axes of the first refraction areas coincide with each other and coincide with the central axes of the eyes of the wearer, so that the imaging units formed by the first refraction areas can be perfectly superposed in the eyes of the wearer to form a complete picture.

Function mirror body 2 with correct 1 integrated into one piece of lens, guarantee function mirror body 2 and correct 1 seamless connection of lens, avoid correcting the lens 1 and correct the lens between the air appears, influence the light irradiation route.

Specifically, the functional lens body 2 can adopt and is not limited to the following values, the cross section of the functional lens body 2 is a tangent circle, the diameter of the tangent circle is 1mm, and the height of the protrusion of the functional lens body 2 is 0.015 mm. The first dioptric zone and the second dioptric zone alternately diffuse towards the lens edge, taking the center of the corrective lens 1 as the diffusion center, the surface coverage of the second dioptric zone being 20%.

As an optional implementation mode of the invention, due to the unique physiological mechanism of the eyeballs, the refraction of the eyes has asymmetry in the upper, lower, left and right directions, and the asymmetry amount of each eyeball is different, and researches show that aiming at different physiological characteristics of each area of the eyeballs, the matched lenses are selected, which is beneficial to relieving eye fatigue. In the present embodiment, the corrective lens 1 includes a central area 31, a first sector area 32, a second sector area 33, a third sector area 34 and a fourth sector area 35, each of which is arranged around the central area 31; the refractive power of each first refraction area in the same area is the same, and the refractive power of each first refraction area in different areas is matched with the myopia degree of the corresponding area of the eye; the cross sections of the functional lens bodies 2 in the same area have the same shape and size, and the cross sections of the functional lens bodies 2 in different areas have the same shape and size or different sizes. The optional implementation rule is that the eyeball area with higher myopia degree is matched with stronger light, that is, the eyeball area with higher myopia degree is the area with higher myopia degree, the cross section diameter of the corresponding functional lens body 2 is smaller (the refractive power is larger), and/or the height of the corresponding functional lens body 2 is larger, and/or the width of the corresponding second refraction area is wider.

Specifically, the functional lens body 2 can adopt and is not limited to the following values, the cross section of the functional lens body 2 is a tangent circle, the diameter range is 0.5mm-1.5mm, and the protruding height of the functional lens body 2 is 0.015mm-0.05 mm. The center of the correcting lens 1 is taken as a diffusion center, the first refraction area and the second refraction area alternately diffuse to the edge of the lens, and the surface coverage rate of the second refraction area is 5-30%.

In addition, since the functional lens body 2 is small in size, in view of the limitations of detection technology and processing technology, the central lens region 31, the first fan-shaped region 32, the second fan-shaped region 33, the third fan-shaped region 34 and the fourth fan-shaped region 35 are processed respectively according to the physiological characteristics of each eyeball region, and the manufacturing cost is high, which is not favorable for mass production. The cross section of all the functional lens bodies 2 can be produced and manufactured according to the same specification, and the scattered light beams can be formed in front of the retina, cannot form images on the retina, cannot burden the eyes of a wearer, cannot induce backward adjustment of the eyes due to light rays which are not formed images, and avoids the deepening of the myopia degree.

As an alternative embodiment of the invention, the smaller the cross-sectional diameter of each functional lens body 2 (the larger the refractive power) from the center of the correction lens 1 to the edge of the correction lens 1, and/or the larger the height of each functional lens body 2, and/or the wider the width of each second refractive area. Because the light sensitivity of eyes is different, the light sensitivity of the middle position of the eyes is higher, the light sensitivity of the edge area of the eyes is lower, the edge area of the correcting lens 1 is corrected, and the effect of the light beam with stronger matched light is better.

In summary, the invention provides a pair of myopia glasses lens for protecting the vision of the eyes, through the way of adding the annular convex lens on the correcting lens 1, a discrete light beam which is not imaged is formed in front of the retina, the light ray which is not imaged can not induce the eyes to adjust backwards, and the myopia degree is prevented from being deepened. The quantity of the functional lens bodies 2 is a plurality of, the lantern ring form that increases progressively is moved and is arranged on the correction lens 1, and a clearance (clearance area is the first refraction area) is left between each functional lens body 2, and the function of the vision is corrected to ordinary myopia spectacle lens can be perfectly realized in the clearance area, and the wearer can see clearly articles at a distance through the interval area. The myopia patient wears the myopia spectacle lens for protecting the eyesight, which can normally see the far and near pictures clearly and can keep wearing at any time; and discrete light beams provided by the functional lens body 2 can be received in real time, so that the myopia degree deepening can be effectively slowed down.
