Description

Technical Field

[0001] The invention belongs to the technical field of glasses, in particular to a pair of defocus glasses for treating hyperopia. Background Art

[0002] When the eye does not use its accommodative power, parallel light rays focus on a point behind the retina after passing through the eye's refractive system instead of focusing on the retina. This is called hyperopia. Hyperopia requires a certain amount of accommodative power when looking at distant objects, and a greater amount of accommodative power when looking at near objects. This can easily lead to visual fatigue and accommodative esotropia. Some children even cannot form a clear image on the retina when looking at distant or near objects due to insufficient accommodative power, which eventually leads to amblyopia. Hyperopia seriously endangers the eye health of children and adolescents, and requires active treatment.

[0003] Studies have confirmed that the peripheral retina plays a more important role in the development of the eyeball than the central retina. The peripheral retina has more neurons than the central retina and is more sensitive to defocus signals. The retina can accurately identify the defocus direction. When a negative lens is attached in front of the eye, the peripheral retina will recognize the hyperopic defocus signal. In order to form a clear image on the retina, the brain will activate the compensatory mechanism of the sclera and choroid, causing abnormal growth of the eyeball.

[0004] Currently, peripheral retinal myopia defocus lenses are widely used in clinical practice to control the development of myopia. The treatment theory is that myopic defocus signals inhibit axial growth and delay the development of myopia; on the contrary, hyperopic defocus signals promote axial growth and reduce hyperopia, so hyperopic defocus lenses can be used to reduce hyperopia.

[0005] At present, the treatment of hyperopia relies on hyperopia glasses when needed. Such glasses can only make the external image form on the retina, but cannot promote the growth of the eye axis. Some patients with high hyperopia cannot achieve a rapid reduction in hyperopia by relying solely on the physiological growth of the eye axis, resulting in the need to wear hyperopia glasses in adulthood. Therefore, we propose a defocus glasses for treating hyperopia. Summary of the invention

[0006] In order to solve the problem raised in the above background technology that the current treatment of hyperopia relies on hyperopia glasses when needed, which can only form external images on the retina but cannot promote the growth of the eye axis, and some high hyperopia patients cannot achieve a rapid reduction in hyperopia by relying solely on the physiological growth of the eye axis, resulting in the need to wear hyperopia glasses after adulthood, the present invention provides a defocus glasses for treating hyperopia.

[0007] To achieve the above object, the present invention provides the following technical solution: a defocus glasses for treating hyperopia, comprising: A hyperopic defocused spectacle lens, wherein the hyperopic defocused spectacle lens is a convex lens, a central telescopic optical zone is arranged at the center of the convex lens, and hyperopic defocused micro lenses are evenly distributed around the circumference of the central telescopic optical zone.

[0008] Preferably, the diameter of the central telescopic optical zone is 10 mm.

[0009] Preferably, the hyperopic defocus microlenses are micro-concave lenses with a diameter of 1.0 mm and an additional diopter of -3.0D, and the hyperopic defocus microlenses are distributed in a circular ring with an inner diameter of 10 mm and an outer diameter of 30 mm.

[0010] Preferably, the number of the hyperopic defocus microlenses is 761, and the 761 hyperopic defocus microlenses are distributed in a circular ring with an inner diameter of 10 mm and an outer diameter of 30 mm.

[0011] Preferably, the 761 hyperopic defocused microlenses are arranged in 12 circular rings, and the diameter of the hyperopic defocused microlenses is 1.0 mm, and adjacent hyperopic defocused microlenses are tangent to each other.

[0012] Preferably, each of the hyperopic defocus microlenses can form hyperopic defocus, and can simultaneously obtain clear central vision and peripheral retinal hyperopic defocus.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention adds a peripheral negative defocus lens to the previous hyperopia glasses, causing the object image to form hyperopic defocus on the peripheral retina. After the peripheral retina recognizes the hyperopic defocus signal, the brain will activate the compensatory mechanism of the sclera and choroid in order to form a clear object image on the retina, causing abnormal growth of the eyeball, thereby increasing the speed of reducing the hyperopia degree.

[0016] The following is combined with Figure 1-2 The present invention is described in further detail.

[0017] In this embodiment, a defocused eyeglass for treating hyperopia is provided. At present, hyperopia treatment relies on hyperopia glasses when necessary. Such glasses can only make the external image form on the retina, but cannot promote the growth of the eye axis. Some high hyperopia patients cannot achieve a rapid reduction in hyperopia by relying solely on the physiological growth of the eye axis, resulting in the need to wear hyperopia glasses after adulthood. The problems include: The hyperopic defocused glasses lens 1 is a convex lens, a central telescopic optical zone 2 is arranged at the center of the convex lens, and hyperopic defocused micro lenses 3 are evenly distributed around the circumference of the central telescopic optical zone 2.

[0018] The diameter of the central telescopic zone 2 is 10 mm.

[0019] The hyperopic defocused microlenses 3 are microconcave lenses 3 with a diameter of 1.0 mm and an additional diopter of -3.0 D, and the microconcave lenses 3 are distributed in a circular ring with an inner diameter of 10 mm and an outer diameter of 30 mm.

[0020] Embodiment 1: There are 761 hyperopic defocus microlenses 3, and the 761 hyperopic defocus microlenses 3 are distributed in a circular ring with an inner diameter of 10 mm and an outer diameter of 30 mm, and the diameter of the central visual hyperopic zone 2 is 10 mm, the 761 hyperopic defocus microlenses 3 are arranged in 12 rings, and the diameter of the hyperopic defocus microlenses 3 is 1.0 mm, and the refractive power of the defocus microlenses is -3.0D, each hyperopic defocus microlens 3 can form hyperopic defocus, and clear central vision and peripheral retinal hyperopic defocus can be obtained at the same time, and adjacent hyperopic defocus microlenses are tangent to each other.

[0021] Using the above solution: Figure 1 The lens 1 for farsightedness defocused glasses is placed in front of the eyes. The lens is a convex lens. Figure 2 The figure shows the planar structure of the hyperopic defocus glasses. In the center of the lens is a 10mm central hyperopic optical zone 2. The diopter of this optical zone is the basic diopter. Around the circular area with an inner diameter of 10mm and an outer diameter of 30mm, 761 hyperopic defocus microlenses 3 with a diameter of 1.0mm and a diopter of -3D are distributed. Each lens can form hyperopic defocus, and the microlenses are closely arranged to form about 12 rings, as shown in FIG. Figure 2 As shown: The image is refracted by the peripheral defocus area of ​​the lens and the light of the intraocular refractive system and formed behind the retina, so that clear central vision and peripheral retinal hyperopic defocus can be obtained at the same time.

[0022] The patent of this invention can increase the peripheral negative defocus area on the basis of ordinary hyperopia glasses, causing the object image to form hyperopic defocus on the peripheral retina. After the peripheral retina recognizes the hyperopic defocus signal, the brain will activate the compensatory mechanism of the sclera and choroid in order to form a clear image on the retina, causing abnormal growth of the eyeball, thereby increasing the speed of reducing hyperopia.

[0023] Adding negative defocus lenses to the periphery causes hyperopic defocus in the peripheral retina. The amount of hyperopic defocus is very critical, because children's eyes have a large adjustment function. Small defocus can be automatically adjusted by the human eye, which cannot achieve the effect of hyperopic defocus in the peripheral retina. The consensus on children's refractive correction points out that hyperopia greater than +3.00D must be corrected, because it is difficult for children to achieve clear vision through adjustment for hyperopia greater than +3D. Even if they can adjust, it will cause binocular vision dysfunction or other functional visual disorders. Therefore, the peripheral hyperopic defocus is set to 3D, that is, a -3D negative lens is added to the peripheral area in the lens design.

[0024] It should be supplemented that, in addition to being circular, the hyperopic defocused microlens 3 can also be a polygon, such as a pentagon, a hexagon, etc., and two adjacent polygons share a common side.

[0025] The glasses of the present invention can effectively correct hyperopia through special design, so that patients can obtain clearer visual experience, which is particularly important for children with high hyperopia. The hyperopia defocus technology promotes the rapid growth of the patient's eye axis, thereby accelerating the reduction of hyperopia. Hyperopic children are in a critical period of visual development. Timely treatment of hyperopia can intervene in amblyopia, strabismus, and visual fatigue. The present invention adopts microlens technology, and the microlenses are closely arranged in a circular shape. Any two adjacent microlenses are tangent to each other. This personalized design not only improves the correction effect, but also improves the comfort of wearing.

[0026] The present invention combines conventional hyperopia glasses with micro-concave lens peripheral hyperopia defocusing technology, which can simultaneously obtain clear central vision and peripheral retinal hyperopia defocusing, thereby accelerating the reduction of hyperopia.

[0027] The present invention adopts microlens technology, the microlenses are closely arranged in a circular shape, and any two adjacent microlenses are tangent to each other. This personalized design not only improves the correction effect, but also improves the wearing comfort.
