Description

Technical Field

[0002] In recent years, the myopia rate among young people in my country has been increasing year by year. In order to improve their myopia symptoms, myopia prevention and control products with different functions have appeared on the market. Optical modules are installed on them, which can irradiate therapeutic light to the fundus of the human eye, thereby playing a therapeutic role.

[0003] In order to adapt to the pupil distance of different users, existing myopia prevention and control products need to frequently adjust the positions of the two optical modules on the myopia prevention and control products during use so that the optical modules are aligned with the pupils. Figure 1 As shown, when the myopia prevention and control product adjusts the position of the optical module 6, the movement path of the two optical modules 6 is "V"-shaped, that is, while the distance between the two optical modules 6 is increased, the two optical modules 6 will simultaneously move to the side away from the pupil 8, so that the distance between the optical module 6 and the pupil 8 becomes larger, resulting in the light spot formed by the therapeutic light on the pupil 8 becoming larger, thereby changing the eye-entering power of the therapeutic light. Correspondingly, when the distance between the two optical modules 6 is reduced, the two optical modules 6 will simultaneously move to the side close to the pupil 8, so that the distance between the optical module 6 and the pupil 8 becomes smaller, and the light spot formed by the therapeutic light on the pupil 8 becomes smaller, thereby also changing the eye-entering power of the therapeutic light.

[0004] Therefore, when the above-mentioned myopia prevention and control products adjust the positions of the two optical modules, the light spot size and the power entering the eye generated by the optical modules will become unstable, thereby affecting the treatment effect. Utility Model Content
