Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of glasses, specifically is a vision delaying lens with microstructure. BACKGROUND

[0002] With the acceleration of modern life rhythm and the popularity of electronic equipment, myopia has become a widespread vision problem in the world, especially among teenagers. Myopia not only affects the quality of daily life, such as learning, work and entertainment, but also may lead to high myopia as the disease progresses, increasing the risk of serious eye diseases such as retinal detachment and glaucoma. Therefore, effectively controlling the development of myopia, especially the prevention and control of myopia in children and adolescents, has become an important issue in the field of public health.

[0003] Traditional myopia correction methods mainly include wearing frame glasses, contact lenses, and corneal molding lenses (OK lenses) that have emerged in recent years. Among them, frame glasses are still the preferred correction method for most myopia patients due to their convenience and high safety. However, although traditional glasses can make the patient's vision clear, they have limited effect on controlling the progression of myopia. Studies have shown that although the existing glasses focus on imaging on the retina, the peripheral imaging falls behind the retina, which can easily cause hyperopic defocus, stimulate the axial elongation of the eyeball, and may lead to deepening of myopia. SUMMARY

[0023] The following is further detailed by specific implementation:

[0024] The reference signs in the attached drawings of the specification include: correction center 1, annular treatment area 2, defocus structure 3, lens group 4, lens main body 5, ear lens 6, light micro-particle 7.

[0025] EMBODIMENT

[0026] A kind of vision delaying lenses with microstructure, as shown in the attached Figure 1 It includes lens main body, and lens main body is equipped with correction center 1, and annular treatment area 2 with correction center 1 as center.In this embodiment, correction center 1 is circular with diameter 6.9 millimeters, and annular treatment area 2 is circular ring with the circular as center.Correction center 1 is used to correct the vision of wearer, provides clear field of view, and annular treatment area 2 is used to defocus, delays myopia development.

[0027] As shown in the attached Figure 2 Annular treatment area 2 is equipped with several lens groups 4, and lens group 4 includes lens main body 5, and two ear lenses 6 that are circumscribed with lens main body 5.Ear lens 6 diameter is less than the diameter of lens main body 5 in the same lens group 4, and two ear lenses 6 in the same lens group 4 are apart.Ear lens 6 defocus amount is less than the defocus amount of lens main body 5 in the same lens group 4, and in this embodiment, the defocus amount of ear lens 6 is 3.5D, and the defocus amount of lens main body 5 is 4.5D.

[0028] Multiple lens groups 4 form defocus structure 3, and defocus structure 3 is annularly distributed with correction center 1 as center.Defocus structure 3 annular distribution forms multiple concentric defocus rings, and the number of defocus structure 3 of each defocus ring is same.Along the radial direction of lens main body, the circumference of initial defocus ring is less than the circumference of terminal defocus ring, and the number of lens group 4 of each defocus structure 3 in terminal defocus ring is greater than the number of lens group 4 of each defocus structure 3 in initial defocus ring, that is, the number of lens group 4 in defocus structure 3 of defocus ring away from correction center 1 is greater than the number of lens group 4 in defocus structure 3 of defocus ring adjacent to correction center 1.Defocus structure 3 of adjacent defocus ring is staggered arrangement.In this embodiment, the number of defocus ring is eleven, and along the radial direction of lens main body, from correction center 1 outward, the number of lens group 4 in defocus structure 3 of defocus ring is 1,2,2,2,3,3,3,4,4,4,5 in turn.

[0029] In other embodiments, there are seventeen defocus rings, arranged radially from the correction center 1 outwards along the lens body. The number of lens groups 4 in the defocus structure 3 of the defocus rings are 1, 1, 2, 2, 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 6 in sequence.

[0030] A straight line passing through the axis of the correction center 1 and the lens body 5, with two ear lenses 6 of the same lens group 4 as the lens body 5 located on the same side of the straight line. In other embodiments, the lens body 5 of the lens group 4 in the same defocusing ring is internally tangent to one ear lens 6 in a circle centered at the correction center 1, and the other ear lens 6 is located within the circle.

[0031] In this design, the lens group 4 alters the refractive power, thereby changing the refractive power of the lens body. This results in a difference in refractive power between the correction center 1 and the annular treatment area 2, causing the convergent image of the correction center 1 to fall onto the retina, while the peripheral image of the annular treatment area 2 also falls onto or in front of the retina. By controlling the imaging position of the lens, the elongation of the eye axis is effectively controlled, thus slowing down the progression of myopia. Simultaneously, the lens body 5 is relatively large, while the ear lens 6 is smaller. The lens body 5 and ear lens 6 together form a cartoon image, and multiple lens groups 4 form a defocus structure 3, distributed in a ring on the lens body. This cartoon-image lens group 4, distributed on the lens body, attracts the attention of buyers through its cartoon image, increasing sales, while reducing the resistance of teenagers with myopia to eyeglasses, thus contributing to the prevention and treatment of myopia in this population.

[0032] In this scheme, the setting of several light microparticles 7 changes the light intensity of light after passing through the annular treatment area 2, thereby reducing the light intensity of light after passing through the lens, thus reducing the contrast of the lens, thereby reducing the visual difference between the affected cone cells and normal cone cells, effectively reducing the stimulation of the axial length of the eye by controlling the light sensitivity of the cone cells, and further delaying the development of myopia.

[0033] Example 2

[0034] A vision-delaying lens with a microstructure, the difference between this embodiment and Embodiment 1 is as follows: as shown in the attached... Figure 3 As shown, a plurality of light microparticles 7 are also formed on the lens body, and the light microparticles 7 are evenly distributed. Specifically, the light microparticles 7 are located in the annular treatment area 2 and do not overlap with the lens body or the ear lens 6. In this embodiment, the axis of the light microparticles 7 is parallel to the optical axis of the lens, that is, a straight line passing through the optical center of the lens body and perpendicular to the front surface of the lens body is parallel to the axis of the light microparticles 7. In other embodiments, the axis of the light microparticles 7 is perpendicular to the side of the lens body.

[0035] The front surface of the lens body is the side of the lens away from the eye, which is usually convex or flat, so as to receive light from the outside and guide it to the inside of the eye. The back surface of the lens body is the other side of the lens, which is usually concave, so as to match the curvature of the eyeball.

[0036] In the scheme, the arrangement of a plurality of light micro-particles 7 changes the illumination intensity of the light passing through the annular treatment area 2 by the light micro-particles 7, thereby reducing the illumination intensity of the light passing through the lens, reducing the contrast of the lens, reducing the visual difference between the affected cone cells and the normal cone cells, effectively reducing the stimulation of the eye axis by controlling the photosensitive condition of the cone cells, and further delaying the development of myopia.
