Myopia deepening originates from "peripheral hyperopia defocus". Traditional myopia glasses only solve the problem of "seeing clearly", but do not interfere with the pathological process of eye growth. Defocus lenses rely on microlenses to make peripheral myopia defocus (the focus falls in front of the retina). This positive visual signal will send the order of "stop growth" to the eye, inhibit the elongation of the eye axis, and scientifically prevent and control juvenile myopia. Mingshi optometry department is equipped with defocus inspection equipment (MRT) to distinguish the defocus state of hyperopia and myopia, adapt more scientific functional frame glasses, and control the development of myopia in a personalized manner.

1、 Peripheral defocus Technology:

The optical microstructure specially arranged on the surface of defocus lenses actively builds a stable myopic defocus optical space in the peripheral region of the retina, so that the peripheral imaging focus accurately falls in front of the retina, on the premise of ensuring clear imaging of the central field of vision and meeting the needs of daily vision. This positive visual signal can inhibit the overgrowth of the eyeball and slow down the abnormal elongation of the ocular axis.

2、 Point diffusion dot technology:

Point diffusion dot technology is also known as contrast regulation theory. Through special optical design, this technology gently reduces the imaging contrast of peripheral retina, weakens the stimulus signal of peripheral blurred image on eye development, and accurately regulates the growth signal intensity received by the eye. By pre drying the visual perception feedback of the retina, the compensatory overgrowth of the eyeball can be suppressed from the root, and the elongation speed of the ocular axis can be effectively delayed.

3、 Ming Vision & Ophthalmology fitting service:

1. comprehensive eye examination:in addition to the basic visual acuity examination, it includes a full set of assessments of diopter, axial length, corneal curvature and binocular visual function to customize personalized prevention and control programs for adolescents.

2. accurate parameter measurement:professional equipment is used to accurately measure the distance and single eye pupil height, strictly control the measurement error, ensure that the optical center of the lens is aligned with the child's visual axis, and give full play to the role of prevention and control.

3. selection of suitable mirror frame:the selected mirror frame should be of appropriate size, strong stability, good fit between the nose bracket and the mirror leg, and at the same time, strictly control the eye distance and forward tilt angle of the mirror to reduce optical deviation.

4. regular follow-up review: professional review should be carried out every 3-6 months to monitor the changes of visual acuity, diopter and ocular axis, and the intervention plan should be dynamically adjusted according to the child's eye use and ocular axis development.
