Title:
VISION CORRECTION LENSES AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/016440
Kind Code:
A1
Abstract:
A preparation method for surrounding defocus-controllable aspherical vision correction lenses. The method comprises the following steps: calculating and judging conditions needed by the human eyes forming myopization defocus by examining shapes of human eye retinas, peripheral defocusing amounts of naked human eyes or peripheral defocusing amounts of human eyes with glasses; forming, according to the conditions obtained by myopization defocus, a distribution solution that the refractive power of each vision correction lens changes along with the change of an aperture; and manufacturing the vision correction lenses according to the obtained distribution solution of the refractive power of the vision correction lenses; after the refractive power of the vision correction lenses is attached to the human eyes, refractive power distribution, formed on the retinas by whole eye refractive power, is larger in a peripheral area than in a central area and is fallen in front of the retinas so as to form myopic defocus. Also disclosed are extra-ocular vision correction lenses, orthokeratology contact lenses and internal oculoscope which are prepared according to the method.
