[0002] Glasses are optical devices used to improve vision, protect the eyes, or serve as decoration. They consist of two parts: lenses and frames. Lenses are typically prismatic lenses. The convex lens portion of a prismatic lens allows the eyes to relax and adjust when looking at close objects, while the prism portion of a prismatic lens resolves the conflict between accommodation and convergence. Together, these two components can more effectively meet the physiological needs of the eye, preventing eye fatigue and worsening of myopia caused by prolonged close-up use.

[0003] In order to prevent the lenses from falling off easily, especially in the event of an accidental fall, to avoid damage or loss, glasses in the prior art are usually rigidly clamped to the frame. However, during long-term use, dust and dirt will appear between the frame and the lenses. Dust and dirt are difficult to clean, affecting wearing comfort and lens clarity. In addition, it is inconvenient to remove the lenses because the clamping force is too tight.

[0004] Therefore, those skilled in the art have proposed a pair of anti-fatigue eye protection glasses that can prevent myopia from getting worse, so as to solve the problems raised in the background art. Utility Model Content

[0028] The upper half of the prism combination lens 1 is constructed with a defocusing area, which is composed of a ring area composed of several concentric circles. The lower half is constructed with a combination area, which is a combination of prisms and lenses, and the thickness gradually decreases from the base to the top.

[0029] refer to Figure 5 and Figure 6 The outer side of the frame 2 is provided with an L-shaped groove 8, and a groove 9 is provided on the horizontal section of the L-shaped groove 8. The hinge 4 is embedded in the L-shaped groove 8, and its horizontal section is provided with a fixing seat 10 facing the groove 9.

[0030] refer to Figure 5 and Figure 6 The frame 2 is provided with a fixing hole 12 communicating with the groove 9 , and a threaded pin 20 is inserted into the fixing hole 12 , and one end of the threaded pin 20 is threadedly connected to the fixing seat 10 .

[0031] During the specific installation, the hinge 4 is embedded in the side wall of the frame 2 through the L-shaped groove 8, the fixing seat 10 on the hinge 4 is inserted into the inner side of the groove 9 and aligned with the fixing hole 12, and then the threaded pin 20 is inserted from the other side of the fixing hole 12 until its bottom end contacts the fixing seat 10 and then the threaded pin 20 is rotated so that it is screwed into the fixing seat 10, thereby completing the installation of the hinge 4.

[0032] refer to Figure 1 A through slot 11 is transversely formed on the inner side of the fixing seat 10 , and one end of the through slot 11 is communicated with the fixing hole 12 .

[0033] refer to Figure 1 The positioning assembly includes a slider 13, a latch 14 and a return spring 15. The slider 13 is slidably arranged in the through groove 11, and one side of the slider is connected to the latch 14 and the return spring 15. One end of the return spring 15 abuts against the end groove wall of the through groove 11. The return spring 15 is sleeved on the latch 14, and one end of the latch 14 extends to the range of the frame 2. A positioning hole 16 for inserting the latch 14 is opened on the side of the inner retaining ring 7.

[0034] Among them, the slider 13 will enter the range of the fixing hole 12 under the support force of the return spring 15 when there is no external force. Therefore, when the threaded pin 20 is inserted, the end of the threaded pin 20 will squeeze the slider 13, causing the slider 13 to move into the through groove 11. During the movement, the through groove 11 will squeeze the return spring 15 and drive the pin 14 to insert into the positioning hole 16 of the inner retaining ring 7, thereby realizing the positioning and installation of the inner retaining ring 7.

[0035] refer to Figure 7 The side of the slider 13 is provided with an inclined surface 17, which is used to make way and slide in the through groove 11 when the threaded pin 20 is inserted.

[0036] During installation, when one end of the threaded pin 20 is inserted into the fixing hole 12 , the end thereof will press the slider 13 along the inclined surface 17 . When the slider 13 is subjected to the squeezing force, it will give way and displace, and then slide laterally along the through slot 11 .

[0037] refer to Figure 2 and Figure 5 A conical plate 18 is provided at one end of the hinge 4, and a pressing groove 19 is provided on the outer side of the connection portion between the leg 5 and the hinge 4, which is used for limiting the conical plate 18 when the leg 5 is opened.

[0038] The cooperation between the pressing groove 19 and the conical plate 18 limits the rotation angle of the supporting leg 5 to ensure its stability when worn.

[0039] Working principle: The defocus area of ​​the prismatic combination lens 1 is mainly used for looking at distant objects, while the convex lens part in the combination area can relax the eyes when looking at nearby targets. The prism part is responsible for resolving the contradiction between accommodation and convergence, so that during use, the eye axes of the two eyes in the triple movement of the endophthalmos and ectophthalmos will be excessively abducted to form a negative convergence, which is driven by the negative convergence to form a negative accommodation, so that the refractive power of the eye is reduced, thereby preventing the occurrence and development of myopia. When installing the prismatic combination lens 1, first fit the hinge 4 on the frame 2, then fit the prismatic combination lens 1 on the inner side of the outer retaining ring 6, and then align the inner retaining ring 7 and insert it into the frame 2, and finally insert the threaded pin 20 from one side of the fixing hole 12. During the insertion of the threaded pin 20, its end will squeeze the slider 1 3, so that the slider 13 moves into the through groove 11. During the movement, the through groove 11 will squeeze the return spring 15 and drive the pin 14 to insert into the positioning hole 16 of the inner retaining ring 7, thereby realizing the positioning and installation of the inner retaining ring 7. At the same time, one end of the threaded pin 20 contacts the fixing seat 10 and then the threaded pin 20 is rotated so that it is screwed to the fixing seat 10, that is, the installation of the hinge 4 is completed. When it is necessary to remove the inner retaining ring 7 to deal with the dirt in the gap of the prism-transparent combination lens 1, by unscrewing the threaded pin 20, the slider 13 will enter the range of the fixing hole 12 under the support force of the return spring 15 without external force, thereby driving the pin 14 to disengage from the positioning hole 16, and the inner retaining ring 7 can be removed to deal with the dirt between the lens and the frame 2.
