Optical-inspired Reading Glasses with Multi Focus Lenses for Multitasking. This is a progressive multifocas reading glasses. Here is the instruction about the magnification strengths. 1.0x=up 0 down 1.0 1.5x=up 0.5 down 1.5 2.0x=up 0.5 down 2.0 2.5x=up 1.0 down 2.5 3.0x=up 1.0 down 3.0 3.5x=up 1.5 down 3.5
Asymptotic multifocal glasses are the upper optical area of the lens used to look far and the lower optical area used to look near. The degree of the middle gradually change, which used to look at the intermediate area.
We change the curvature of the lens surface from top to bottom, adding positive diopter, which result in the effect of visual correction. Because the degree is gradual, the substitution of the regulation is also based on the shortening of the distance, there is no fluctuation in regulation. As a result, the glasses won
