Hybrid refractive holographic single vision spectacle lenses

Abstract

In this contribution, we investigate hybrid single vision spectacle lenses (SVSLs) consisting of holographic optical elements (HOEs) embedded into a refractive lens. We evaluate the performance of two examples of hybrid SVSLs in terms of their distributions of spherical error (SPH error), astigmatic error (AST error) and transverse chromatic error (CE) over the lens surface, simulating the optical performance for the patient's rotating eye. We find that, particularly for high prescription values, hybrid SVSLs outperform their purely refractive counterparts in terms of CE with the additional benefit of reducing the lens thickness. As such, we show that hybrid refractive, holographic designs can be a viable alternative to purely refractive SVSLs for high prescription SVSLs.

Achromatic polymer-dispersed liquid crystal lens with diffractive–refractive hybrid structure

“…The imaging quality of the visual optical system is very sensitive to the change of wavelength, so the chromatic aberration of Fresnel lens as a binary diffraction system is well worth studying. The diffractive-refractive hybrid achromatic design method has received a lot of attention from researchers due to its high performance and small size characteristics [20][21][22][23]. However, because of the limitation of materials and complex fabrication processes, these studies can only fabricate lenses with fixed focal length.…”
