Compact Models of Presbyopia Accommodative Errors for Wearable Adaptive-Optics Vision Correction Devices

Subjective accommodation refractive error models are essential for implementing adaptive vision correction devices that utilize varifocal optics. This article describes compact empirical of subjective accommodative errors in subjects with advanced presbyopia. The based on measurements from fifteen presbyopes over the age 45 using commercially available focus-tunable eyeglasses under three different illumination conditions a 3.08D stimulus range. resulting average residual root-mean-squared (RMS) values best fitting 8-parameter model was 0.25D compared to an RMS 0.4D conventional DDF and HHG models. best-fitting is below human eye.
