Patent number: 11963868Abstract: A double-sided aspheric diffractive multifocal lens and methods of manufacturing and design of such lenses in the field of ophthalmology. The lens can include an optic comprising an aspheric anterior surface and an aspheric posterior surface. On one of the two surfaces a plurality of concentric diffractive multifocal zones can be designed. The other surface can include a toric component. The double-sided aspheric surface design results in improvement of the modulation transfer function (MTF) of the lens-eye combination by aberration reduction and vision contrast enhancement as compared to one-sided aspheric lens. The surface having a plurality of concentric diffractive multifocal zones produces a near focus, an intermediate focus, and a distance focus.Type: GrantFiled: May 27, 2021Date of Patent: April 23, 2024Assignee: AST Products, Inc.Inventors: Yi-Feng Chiu, Chuan-Hui Yang, Wen-Chu Tseng
