Abstract

Spectacle lens are used to compensate refractive errors of the eyes. Therefore, the properties of human eyes were taken into consideration in our research. We not only designed and optimized the lens with the required optical performance in ZEMAX based on the eye-lens system, but also calculated the sag of the aspherical surface according to the optimized parameters. The back surface of the lens was aspherical surface for the better clinical effects than other types of aspherical lens. The results data were subsequently imported into the freeform verifier software (FFV) for analysis and the optical properties of the lens were calculated. It was found that the power distribution has been improved. The thickness of aspherical lens was much thinner than the spherical lens. Therefore, our research found a balance between thickness and optical performance.
