Traditional myopia treatment devices such as various eye massage, magnetic therapy, electrotherapy, vibration instrument, eye patch, progressive multifocal mirror and drug patch, etc., its principle of action is based on the mechanism of myopia pathogenesis “regulation theory”. Since there is no direct effect on the two key aspects of myopia onset in students, such as the deprivation of focus and hyperopia, the effect is symptomatic and can help improve visual acuity, but the long-term effect of controlling myopia is almost 100% bad. Modern myopia treatment devices such as virtual focus hyperopia, focusing hyperopia, automatic focus shifting hyperopia, etc., are based on myopia pathogenesis “1 main cause 2 key links”. They can provide virtual or defocused hyperopia and improve the adjustment sensitivity, thus offsetting the “nearness”, blocking the two key links of hyperopic defocus and form deprivation, and promoting the transformation of myopia to hyperopia. Therefore, the modern myopia treatment instrument belongs to the myopia treatment instrument, clinical observation, its long-term effect of controlling myopia can reach more than 80%. The main feature of modern myopia treatment devices is the effect of farsightedness. Traditional myopia treatment instruments do not have this function. Therefore, modern myopia treatment instruments are also called farsighted myopia treatment instruments, which are mainly composed of various farsighted mirrors. The first generation: non-farsighted mirrors (instruments): have a certain indirect farsightedness (loosening adjustment), characterized by not directly providing farsightedness or blocking farsightedness out of focus or form deprivation, but only indirectly affecting adjustment and improving visual symptoms. Such as various eye massagers,, magnetic therapy, electrotherapy, vibration instrument, eye patch, progressive multifocal lens and drug patch, etc. The second generation: virtual focal distance lenses (belonging to the static base type of distance lenses): (1) can be virtualized by prismatic convex mirror to look at the near refractive focus to 5 meters away from the far side to offset the “look at the near” and its cause of form deprivation of myopia; (2) can provide virtual farsightedness, producing myopic defocus, thereby offsetting the adjustment lag caused by farsightedness defocus (2) can provide virtual hyperopia, producing myopic defocus, thereby offsetting the hyperopic defocus caused by accommodation lag. Such as patch type, table or frame type defocusing telephoto lenses. The third generation: the focus of the distant lens class (i.e. eye sensitivity distant lens, belongs to the dynamic reinforced distant lens): can guide the refractive system of the eye to see far – see near focusing movement, so as to offset the adjustment lag caused by out-of-focus myopia; can guide the eye to expand the 360-degree field of vision sensitive movement, so as to offset the near-visual deprivation myopia. Such as wearing myopic sensitivity telecine or resonance sensitivity telecine. The fourth generation: shift the focus of the distance (i.e., automatic distance lenses, etc., belong to the dynamic reinforcement of distance lenses): can look at the near refractive focus to 5 meters away from the far side to offset the “look at the near” and its resulting form of deprivation of myopia; can offset look at the near 300 ~ 500 degrees of regulatory myopia, so as to immediately reduce the mixed myopia. Virtual focal distance lenses are basic distance lenses that can be used to prevent myopia from occurring or to prevent any degree of myopia from developing. Since its effect is static and virtual, if the stubborn myopia cannot be well controlled, you can add a focusing or shifting focus telephoto lens with dynamic telephoto effect to strengthen the telephoto effect to obtain better telephoto effect.
