Description

Technical Field

[0001] This utility model relates to the field of lens technology, and in particular to a spherical-cylindrical dual-control fusion lens. Background Technology

[0002] With the continuous advancement of technology and the increasing demand for visual health, eyeglass lens technology is also constantly innovating and developing. Against this backdrop, a spherical-cylindrical dual-control fusion lens has emerged, representing a significant breakthrough in the field of modern ophthalmic optics.

[0003] A dual-control fusion lens combining spherical and cylindrical lenses integrates multiple advanced technologies, aiming to provide users with a clearer and more comfortable visual experience.

[0004] The human eye is adaptive. Wearing static defocus lenses for a long time will cause the retina to develop defocus tolerance, that is, static defocus saturation, which weakens the myopia control effect. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a spherical-cylindrical dual-control fusion lens.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a spherical-cylindrical dual-control fusion lens, comprising a lens body, characterized in that: the lens body includes a base layer, and the surface of the lens body is further provided with an anti-reflective layer, an anti-ultraviolet layer, an impact-resistant layer, a photochromic layer, and a stain-resistant layer; one side of the base layer is fixedly bonded to the anti-reflective layer with resin adhesive, the other side of the anti-reflective layer is fixedly bonded to the anti-ultraviolet layer with resin adhesive, the other side of the anti-ultraviolet layer is fixedly bonded to the impact-resistant layer with resin adhesive, the other side of the impact-resistant layer is coated with a photochromic layer, and the other end of the photochromic layer is fixedly bonded to the stain-resistant layer with resin adhesive;

[0008] The surface of the base layer is provided with a plurality of microlenses, the center-to-center distance between the plurality of microlenses is 7.98 mm, the defocus area formed by the plurality of microlenses is 49.79 mm in diameter, and the plurality of microlenses are arranged in a ring from the inside to the outside in eighteen layers.

[0009] Through a unique dual-lens design (base layer 1 and base layer 2) combined with a multi-layered microlens distribution structure (microlens 1 and microlens 2), dynamic defocus intervention is achieved. Specifically, the microlens distribution angles of the two lenses differ by 30 degrees, and patients alternate wearing them every 2-4 weeks. This allows retinal cells to receive stimulation from different defocus patterns at different times. Microlens 1 is arranged in 18 rings with a center-to-center spacing of 7.98 mm, forming a defocus area with a diameter of 49.79 mm. Microlens 2 further differentiates the defocus signal through rotational distribution. This design avoids fatigue of visual cells due to long-term fixed-intensity stimulation through alternating stimulation over time. At the same time, the density and position of the defocus pattern contacted by the retina dynamically change when the eye moves or scans, forming a "gradual dynamic defocus." This maintains the myopia control effect while promoting the recovery of visual cells during the alternation, thereby improving the sustainability and physiological adaptability of the intervention.

[0010] In detail, the lens body also includes a base layer II, and a plurality of microlenses II are disposed on the surface of the base layer II. The distribution of the microlenses II is the same as that of the microlenses I, rotated by 30 degrees. The defocusing amount of the microlenses I and the microlenses II is +3.00D to +6.00D.

[0011] In detail, both the first and second base layers are made of synthetic resin materials.

[0012] In detail, the anti-reflective layer is made of zirconium dioxide material.

[0013] In detail, the UV-protective layer is made of zinc oxide.

[0014] In detail, the impact-resistant layer is made of polycarbonate material.

[0015] In detail, the photochromic layer is made of silver halide coating material.

[0016] In detail, the stain-resistant layer is made of perfluoropolyether material.

[0017] The design scheme proposed in this utility model has the following beneficial effects in application:

[0018] 1. This solution significantly enhances functionality through a multi-layered composite structure design (anti-reflective layer, UV protection layer, impact-resistant layer, etc.). The zirconium dioxide anti-reflective layer achieves a light transmittance of over 98% and reduces glare. The zinc oxide UV protection layer effectively blocks UV damage. The polycarbonate impact-resistant layer enhances safety. The photochromic layer enables adaptive adjustment between indoor and outdoor environments. The stain-resistant layer reduces cleaning difficulty. In addition, the microlenses in the first and second base layers are distributed with a 30-degree rotation. Combined with a two-lens-per-person alternating wearing mechanism (alternating every 2-4 weeks), dynamic defocus stimulation avoids fatigue of retinal cells caused by fixed stimulation and promotes their rotation and recovery, thereby more scientifically intervening in the development of myopia.

[0019] 2. As described in point 1, the lens adopts dual control of spherical and cylindrical lenses and nano-lithography technology. It achieves multi-point defocusing through 18 layers of ring-distributed microlenses (center spacing 7.98mm, defocus area 49.79mm) to precisely control the light path. The design of microlens 2 rotating 30 degrees relative to microlens 1, combined with the gradual dynamic defocusing generated by eye movement and saccades, allows the retina to receive light signals of different densities and patterns, avoiding adaptive fatigue of visual cells. The synthetic resin base layer is both lightweight and impact-resistant, combined with photochromic and stain-resistant properties, to meet the needs of multiple usage scenarios and comprehensively improve visual comfort and myopia control.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-4 A spherical-cylindrical dual-control fusion lens includes a lens body, which comprises a base layer 1. The surface of the lens body is further provided with an anti-reflective layer 3, an anti-ultraviolet layer 31, an impact-resistant layer 32, a photochromic layer 33, and a stain-resistant layer 34. The anti-reflective layer 3 is bonded to one side of the base layer 1 with resin adhesive. The anti-ultraviolet layer 31 is bonded to the other side of the anti-reflective layer 3 with resin adhesive. The impact-resistant layer 32 is bonded to the other side of the anti-ultraviolet layer 31 with resin adhesive. The photochromic layer 33 is coated on the other side of the impact-resistant layer 32. The stain-resistant layer 34 is bonded to the other end of the photochromic layer 33 with resin adhesive.

[0027] The surface of the base layer 1 is provided with a number of microlenses 11. The center-to-center distance between the microlenses 11 is 7.98 mm, the defocus area formed by the microlenses 11 is 49.79 mm in diameter, and the microlenses 11 are distributed in eighteen layers in a ring from the inside to the outside.

[0028] It should be further explained that the lens body also includes a base layer 2, and the surface of the base layer 2 is provided with several microlenses 21. The distribution of the microlenses 21 is the same as that of the microlenses 11, rotated by 30 degrees. The lens body containing either the base layer 1 or the base layer 2 is a two-lens system, where two pairs of glasses are sold to myopic patients at once, and they are worn alternately every 2-4 weeks to achieve dynamic defocus intervention. This allows retinal cells to receive defocus stimulation at different times, and to rest and recover in turn. It adopts a gradual dynamic defocus design, so that when the eyeball rotates / sagittates, the retina can always receive different defocus patterns and microlens stimulation of different densities, avoiding the fatigue of photoreceptor cells from being stimulated by the same intensity for a long time. The defocus amount of the microlenses 11 and the microlenses 21 is +3.00D to +6.00D.

[0029] It should be further noted that both base layer 1 and base layer 2 are made of synthetic resin material, which has good anti-drop and non-breakable effect.

[0030] It should be further noted that the anti-reflective layer 3 is made of zirconium dioxide, which reduces the light reflected from the lens, increases the light transmittance (up to 98% or more), reduces glare, and improves night vision.

[0031] It should be further noted that the UV protection layer 31 is made of zinc oxide material, which protects the eyes from UV damage.

[0032] It should be further noted that the impact-resistant layer 32 is made of polycarbonate material, which enhances the lens's impact resistance and is suitable for sports or industrial protection.

[0033] It should be further noted that the photochromic layer 33 is made of silver halide coating material, which darkens when exposed to ultraviolet light and becomes transparent indoors, making it suitable for use both outdoors and indoors.

[0034] It should be further noted that the stain-resistant layer 34 is made of perfluoropolyether material, which reduces oil and fingerprint adhesion and makes it easy to clean.

[0035] Working Method: This solution utilizes a unique one-person, two-lens design (base layer 1 and base layer 2), combined with a multi-layered microlens distribution structure (microlens 11 and microlens 21), to achieve dynamic defocus intervention. Specifically, the microlens distribution angles of the two lenses differ by 30 degrees, and patients alternate wearing them every 2-4 weeks. This allows retinal cells to receive stimulation from different defocus patterns at different times. Microlens 11 is arranged in 18 layers in a ring with a center-to-center spacing of 7.98 mm, forming a defocus area with a diameter of 49.79 mm. Microlens 21 further differentiates the defocus signal through rotational distribution. This design avoids fatigue of visual cells due to long-term fixed-intensity stimulation through alternating stimulation over time. At the same time, the density and position of the defocus pattern contacted by the retina dynamically change when the eye rotates or scans, forming a "gradual dynamic defocus." This maintains the myopia control effect while promoting the recovery of visual cells during the alternation, thereby improving the sustainability and physiological adaptability of the intervention.

[0036] By employing a multi-layered composite material (anti-reflective layer 3, UV protection layer 31, impact-resistant layer 32, photochromic layer 33, and stain-resistant layer 34), the optical performance and protective functions are synergistically optimized. The anti-reflective layer 3 (zirconia) increases the light transmittance to over 98% and reduces glare. The UV protection layer 31 (zinc oxide) shields against ultraviolet radiation. The impact-resistant layer 32 (polycarbonate) enhances mechanical strength, making it suitable for high-intensity use scenarios. The photochromic layer 33 (silver halide) automatically adjusts the light transmittance according to the UV intensity, achieving seamless switching between indoor and outdoor environments. The stain-resistant layer 34 (perfluoropolyether) reduces the cleaning frequency through its oleophobic and hydrophobic properties. The layers are bonded together with resin adhesive to form a stable structure. The synthetic resin substrates of base layer 1 and base layer 2 further ensure lightweight and shatter resistance. This layered design not only meets the defocusing requirements of myopia control but also, through the integration of materials science, takes into account visual comfort, environmental adaptability, and service life, forming a multi-dimensional comprehensive solution.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
