Manufacturing Technique
Myopia
Above image points out the move oval or prolate shape of the myopic retina -- it's stretched horizontally longer. So when light focuses clearly on that elongated central retina, it is now by default being focused behind the retina in the periphery. This is called peripheral hyperopic defocus, and it's our culprit for myopes worsening and worsening.
(1) How do the YOULI myopia control lenses that can help slow or prevent myopia progression?
*Myopia defocus control technology is the answer.
Well from the pictures above you can find -- it can change the way light focuses on the retina between the central and peripheral retinal areas. Peripheral defocus theory suggests that this designs work at controlling myopia because they create that all important peripheral myopic defocus, interrupting the feedback loop for the eye to continue lengthening that is our bane in glasses and single vision lens wear.
(2) Central refractive correction technology
According to the imaging theory of emmetropia, the core optical zone of the YOULI myopia control lens is around 12mm, and the luminosity is basically not reduced. The retina forms a clear object image to achieve the refractive correction effect.
(3) Does YOULI myopia control lens block blue light?
The answer is YES.
Blue light is divided into two parts: harmful blue light and beneficial blue light according to different wave bands. YOULI myopia control lens has intelligent blue light protection. It uses a substrate absorption technology to add a UV420 blue light absorption factor to the substrate to filter harmful blue light and retain beneficial blue light
