Aspherical wide visual design, soft gentle degree of change, and fully buffered eye fatigue.
From far to near due to Add role, there is a continuous diopter, so that we will look at different distances of objects are ideal clarity, avoiding the look-for-mirror distance nearly frequent trouble.
Coordinated regulation of the human eye, reducing visual fatigue, progressive multifocal glasses light as a result of consecutive increases, the distance of different objects to apply a different refraction, it can serve as the regulating role to help bring them into line with the human eye and normal physical, reduce asthenopia.
Co***red with the double optical lens shape eyesores created, such as jumping obvious defects, the appearance of a progressive piece of ordinary photo film, but also increase the wear of aesthetics.
Targeting young people with eye habits and physiological characteristics of the eye, especially the design of progressive young people delay the progression of effective control in recent films deepening degrees
