Description

Technical Field

[0001] The present invention relates to the technical field of eyeglass lenses, in particular to a lens for treating eye patients and a use method thereof. Background Art

[0002] The most basic function of eyeglass lenses is to correct vision and improve vision problems such as myopia, hyperopia, astigmatism, etc. Different types of eyeglass lenses can be selected according to personal needs, such as myopia eyeglass lenses, hyperopia eyeglass lenses, progressive multifocal eyeglass lenses, etc.

[0003] Many people in life suffer from diseases related to eye length, such as myopia. Myopia refers to blurred vision caused by parallel light rays focusing in front of the retina after passing through the eye's refractive system. It is a type of refractive error. The cause of its formation is not yet clear, but it is often related to genetic factors, bad eye habits and other reasons. Myopia is manifested as parallel light entering the eye and failing to form an image on the retina, resulting in unclear vision at a distance. The eye structure is manifested as an axial length exceeding the normal range or excessive curvature of the cornea and lens. Myopic patients usually wear glasses to correct their vision and improve vision problems such as myopia and astigmatism. The degree of myopia of eye patients will inevitably change after a long time. When the lens degree does not match the patient's myopia degree, since the lens degree cannot be changed, if you want to increase the degree again, you must replace the lens with a new one. Therefore, the cost of changing the lens degree is relatively high. Summary of the invention

[0010] As a preferred solution of the present invention, the central visible optical area of ​​the microlens is 9mm-10mm.

[0011] As a preferred solution of the present invention, the diameter of the microlens is 1 mm, and the distance between two adjacent groups of microlenses is 0.5 mm.

[0012] As a preferred solution of the present invention, the microlens is made of transparent material and is not colored.

[0013] As a preferred solution of the present invention, the microlens is a spherical protrusion, and the microlens and the second lens have the same refractive index.

[0015] As a preferred solution of the present invention, the positioning frame is made of nylon material, and the positioning frame is initially tilted upward. After the positioning frame is assembled with the lens frame, the lens frame will squeeze the positioning frame and drive the card slot to engage with the second lens.

[0016] As a preferred solution of the present invention, the thickness of the second hardened anti-flowering film is 3-5 um, the thickness of the second anti-reflection film is 0.3 um, and the thickness of the second anti-fouling film is 0.005-0.01 um.

[0017] As a preferred solution of the present invention, the second anti-fouling film has the same thickness as the first anti-fouling film, the first hardened anti-flowering film has the same thickness as the second hardened anti-flowering film, and the first anti-reflection film has the same thickness as the second anti-reflection film.

[0018] As a preferred solution of the present invention, the following steps are included:

[0019] S1. Test the degree of myopia of patients and measure the degree of myopia of patients through professional tools and instruments;

[0020] S2. Remove the lens, remove the positioning frame from the frame, and lift the positioning frame outward through the groove to separate the card slot from the second lens, and remove the second lens, and then use a cleaning tool to clean and wipe the second lens;

[0021] S3. Lens assembly: Wear disposable rubber gloves, embed the second lens into the inner side of the slot of the corresponding degree, and assemble the positioning frame into the glasses frame, so that the glasses frame squeezes the positioning frame and drives the slot to position the second lens, completing the assembly and degree adjustment of the second lens.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention can adjust the position of the second lens by the cooperation between the second lens and the slots through the plurality of slots arranged on the inner side of the positioning frame, thereby changing the distance between the second lens and the first lens. When the distance between the second lens and the first lens changes, the propagation of light will be deflected, thereby changing the refractive power to adapt to the different degrees of the patient's eyes, without the need to replace the lens, thereby reducing the cost of replacing the lens degree.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figure 1-7 As shown, the present invention provides a lens for treating an eye patient and a method of using the lens, comprising a positioning frame 1, and further comprising:

[0037] An adjustable lens, which is arranged on the positioning frame 1 and is used to adjust the diopter of the lens according to the patient's degree;

[0038] Among them, the adjustable lens includes a first lens 2, the first lens 2 is embedded in the inner wall of the positioning frame 1, the inner wall of the positioning frame 1 is provided with a plurality of card slots 3, the inner wall of the card slot 3 is embedded with a second lens 4, a groove 6 is provided on the inner side of the positioning frame 1, and a plurality of micro lenses 5 are distributed on the surface of the second lens 4.

[0039] By means of a plurality of card slots 3 arranged on the inner side of the positioning frame 1, the position of the second lens 4 can be adjusted through the cooperation between the card slots 3, so that the distance between the second lens 4 and the first lens 2 can be changed. When the distance between the second lens 4 and the first lens 2 changes, the propagation of light will be deflected, thereby changing the refractive power to adapt to the different degrees of the patient's eyes, without the need to replace the lenses, thereby reducing the cost of replacing the lens degree.

[0040] like Figure 5As shown, the second lens 4 includes a second lens base 41, a second hardened anti-spot film 42, a second anti-reflection film 43 and a second anti-fouling film 44. The second hardened anti-spot film 42 covers the outer wall of the second lens base 41, the second anti-reflection film 43 covers the outer wall of the second hardened anti-spot film 42, and the second anti-fouling film 44 covers the outer wall of the second anti-reflection film 43.

[0041] Through the design of the second anti-reflection film 43, due to the different curvatures of the front and back surfaces of the lens and a certain amount of reflection, internal reflection will occur between them, and the internal reflection will produce a virtual image near the far point spherical surface. When two related wave sources with the same frequency, the same vibration direction and a constant phase difference are superimposed, interference will occur, and the interference will either enhance each other or cancel each other out. Utilizing this principle, a film layer of a certain thickness is plated on the lens, so that the reflected light generated by the front and back surfaces of the film layer interferes and cancels each other out, thereby achieving an anti-reflection effect.

[0042] like Figure 7 As shown, the first lens 2 includes a first lens base 21, a first hardened anti-spot film 22, a first anti-reflection film 23 and a first anti-fouling film 24. The first hardened anti-spot film 22 covers the inner wall of the first lens base 21, the first anti-reflection film 23 covers the inner wall of the first hardened anti-spot film 22, and the first anti-fouling film 24 covers the inner wall of the first anti-reflection film 23.

[0043] Through the design of the first anti-fouling film 24 and the second anti-fouling film 44, the parts of the lens exposed to the outside world can be protected. Since the second anti-reflection film 43 and the first anti-reflection film 23 are microporous structures, oil and dirt can easily penetrate and cause stains on the lens. This problem can be solved by coating a layer of the second anti-fouling film 44 or the first anti-fouling film 24, while also having water-resistant properties.

[0044] like Figure 1 As shown, the central visible optical area of ​​the microlens 5 is 9 mm-10 mm, the diameter of the microlens 5 is 1 mm, and the spacing between two adjacent groups of microlenses 5 is 0.5 mm.

[0045] Through the design of the microlens 5, when the wearer looks far away, part of the light passes through the central single light area, and the other part passes through the lens area, forming a circular defocus state, reducing hyperopic defocus, thereby controlling the development of the eye axis and delaying the development of myopia.

[0046] like Figure 1 , 2 As shown, the microlens 5 is made of transparent material and is not colored. The microlens 5 is a spherical protrusion. The microlens 5 and the second lens 4 have the same refractive index.

[0047] The second lens 4 has many tiny protrusions distributed on its surface. These designs change the focusing position of the light, so that the light forms a focus in front of or behind the retina instead of only on the retina, which helps to reduce the risk of myopia.

[0048] like Figure 3 As shown, the distance between two adjacent groups of card slots 3 is 0.3 mm.

[0049] Through the design of the card slot 3, by changing the position where the second lens 4 is fixed to one group of the card slots 3, the distance between the second lens 4 and the first lens 2 can be changed, and the refractive power of the light passing through the second lens 4 and the first lens 2 will change.

[0050] like Figure 3 As shown, the positioning frame 1 is made of nylon material. The positioning frame 1 is initially tilted upward. After the positioning frame 1 is assembled with the lens frame, the lens frame will squeeze the positioning frame 1 and drive the card slot 3 to engage with the second lens 4.

[0051] Through the design of the positioning frame 1, it has a certain toughness and flexibility, and through the design of the groove 6, the positioning frame 1 has a certain compression space, so that after it is assembled with the frame, the positioning frame 1 drives the card slot 3 to squeeze the periphery of the second lens 4. At this time, the card slot 3 can be firmly fixed on the outer surface of the second lens 4, avoiding the movement of the second lens 4 and avoiding its position displacement to cause a change in degree, thereby improving stability.

[0052] like Figure 6 As shown, the thickness of the second hardened anti-flowering film 42 is 3-5 um, the thickness of the second anti-reflection film 43 is 0.3 um, and the thickness of the second anti-fouling film 44 is 0.005-0.01 um.

[0053] Through the design of the second anti-fouling film 44, it is made as thin as possible to avoid affecting the optical performance of the second anti-reflection film 43. The material of the second anti-fouling film 44 is fluoride, and it is made by immersion method or vacuum coating method.

[0054] like Figure 6 , 7 As shown, the second anti-fouling film 44 and the first anti-fouling film 24 have the same thickness, the first hardened anti-flowering film 22 and the second hardened anti-flowering film 42 have the same thickness, and the first anti-reflection film 23 and the second anti-reflection film 43 have the same thickness.

[0055] Through the design of the second lens 4 and the first lens 2 , the composition structure of both sides of the lens can be the same, ensuring its optical quality and appearance, and the second anti-fouling film 44 and the first anti-fouling film 24 can protect both sides of the lens.

[0056] like Figure 1-7 The following steps are shown:

[0057] S1. Test the degree of myopia of patients and measure the degree of myopia of patients through professional tools and instruments;

[0058] S2. Remove the lens, remove the positioning frame 1 from the frame, and lift the positioning frame 1 outward through the groove 6 to separate the card slot 3 from the second lens 4, and remove the second lens 4, and then use a cleaning tool to clean and wipe the second lens 4;

[0059] S3. Assemble the lenses. Wear disposable rubber gloves, embed the second lens 4 into the inner side of the card slot 3 of the corresponding degree, and assemble the positioning frame 1 into the glasses frame. Make the glasses frame squeeze the positioning frame 1, and drive the card slot 3 to position the second lens 4, and complete the assembly of the second lens 4 and degree adjustment.

[0060] Working principle:

[0061] Through the toughness and flexibility of the positioning frame 1 and the groove 6 opened on the inner side of the positioning frame 1, the positioning frame 1 has a certain compression or expansion space, so that the second lens 4 can move along the inner side of the positioning frame 1, and the second lens 4 is initially limited by the card slot 3. When the distance between the second lens 4 and the first lens 2 changes, the propagation of light will be deflected, thereby changing the refractive power to adapt to the different degrees of the patient's eyes. There is no need to replace the lens, saving the cost of lens replacement. Thereafter, the positioning frame 1 is assembled with the frame, and the frame drives the positioning frame 1 and the card slot 3 to squeeze the periphery of the second lens 4. At this time, the card slot 3 can be firmly fixed on the outer surface of the second lens 4, thereby completing the adjustment of the lens degree.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
