Product Details
What is myopia prevention lens？
- PC myopia defocus lens is based on the principle of multi-point defocus control technology, which is equipped with 1339 continuous dot matrix distributed microlenses. Each microlens has the same diameter and the connected parts constitute the lenticular degree, generating stimulus and defocus signals that can slow axial growth and increase the effective defocus area independently and in series with each other, thus slowing the axial growth and thus slowing the degree of myopia deepening.
Are myopia prevention lenses effective？
- The use of the new technique reduces central blur and corrects not only clear central vision, but also clear peripheral vision images in front of the peripheral retina. As a result of edge blurring in myopia, it helps to slow the growth of the eye axis without affecting normal visual results, and to alleviate the progression of myopia. They've been tested in a lot of experiments, and they're very effective.
The defocus region wider, defocusing amount more stable
Multi-pointmyopia management defocal lens imaging
Clear imaging in the positive focal area
Multi-point myopia management defocal lens imaging
- + 3.5D~+4.5D Center to edge stable defocus compensation microlens, more close to the eyeball physiology and optical imaging form;
- φ10.2~φ63.492mm-Defocus area diameter, and the larger effective defocus area covers more peripheral retinal areas.
- Multi-point myopia management defocus lens is easy to wear, suitable for a wider range of frames, there is no unsuitable problem, high comfort.
More conducive to slow control of myopia deepening
- PC myopia defocus lens is based on the principle of multi-point defocus control technology, which is equipped with 1339 continuous dot matrix distributed microlenses. Each microlens has the same diameter and the connected parts constitute the lenticular degree, generating stimulus and defocus signals that can slow axial growth and increase the effective defocus area independently and in series with each other, thus slowing the axial growth and thus slowing the degree of myopia deepening.
Spherical design designed for clear view areas
- The aspheric design of the mother lens with bright visual areas reduces low-order peripheral aberrations and results in thinner lenses.
Improved the effect of inner ring peripheral blur
- The lens design has a gradient change in focus volume to improve the focus volume of the inner ring microstructure, taking into account the fact that the focus signal close to the center of the field of view has a more significant effect on inhibiting axial growth.
Point matrix propagation design
- The lens design has a gradient change in focus volume to improve the focus volume of the inner ring microstructure, taking into account the fact that the focus signal close to the center of the field of view has a more significant effect on inhibiting axial growth.
