[0002] A myopia treatment instrument refers to a special glasses or instrument with the function of "defocusing" for hyperopia. The myopia treatment instrument is developed under the influence of the form deprivation theory and the defocus theory. For the phenomenon of "near vision", devices such as a far-sightedness mirror and an automatic far-sightedness mirror can be used to provide a hyperopic prism or a zoom hyperopic lens, virtualize near vision into far vision for rest, so as to prevent the occurrence and development of myopia. Blocking "posterior defocus" is the key link. The forward defocus effect generated by a hyperopic lens or an automatic zoom lens in the hyperopic lens can be used to block the posterior defocus during the approach process, thereby promoting the development of the eye axis forward (i.e., in the shortening direction) and preventing myopia. Such as various far-sightedness mirrors or eye sensitivity training instruments, etc. When the existing equipment treats myopia, the light source is usually fixed, resulting in a reduction in the myopia treatment effect.

[0003] When the existing equipment treats myopia patients, the light source is usually fixedly installed, which is not convenient to adjust the position of the light source for treatment. Moreover, the existing equipment cannot conveniently replace the lens structure, and it is not convenient for the lens structure to adapt to different myopia patients for myopia treatment, affecting the treatment effect and practicality of the equipment for myopia treatment. Therefore, the technical personnel in this field provide a myopia treatment instrument with improved clarity to solve the problems raised in the above background technique.

At this time, the placement member 6 drives the fixing rod 17 to insert into the fixing groove 18. Then, the sliding portion 27 at the bottom of the fixing rod 17 squeezes and pushes the locking block 23. Then, the locking block 23 squeezes the spring 21 through the sliding plate 22. At the same time, the sliding plate 22 slides on the outside of the guiding rod 20. When the thrust received by the locking block 23 disappears, the spring 21 squeezes and pushes the sliding plate 22. Then, the sliding plate 22 slides on the outside of the guiding rod 20. Then, the sliding plate 22 drives the locking block 23 to embed into the locking groove 24 to lock and fix the fixing rod 17. Then, rotate the rotating rod 9. At this time, the rotating rod 9 drives the first bevel gear 10 to rotate. Then, the first bevel gear 10 drives the screw rod 12 to rotate through the second bevel gear 13. Then, the screw rod 12 drives the lamp holder 4 on one side of the insulating seat 16 to change its position through the driving block 15. At the same time, the insulating seat 16 drives the guiding block 25 to slide in the guiding groove 26.
