We propose a novel concept of presbyopia-correcting adaptive eyeglasses for people who do not accept current corrective solutions. Our eyeglasses provide clear vision at all distances automatically and feature enhanced field of vision and high optical quality. The adaptive technology relies on an original fluid-filled lens whose focusing power is set by a low-power microfluidic pump inserted in the eyeglass temples. We present our prototype and demonstrate the viability of our technology through its characterization.
We report pupillometry results corresponding to three studies. A first study aims at measuring 2D pupil geometry with high precision (below 2 microns) at high frequency (more than 450Hz). The two other studies aim at measuring 3D pupil movements, with and without a chin rest. Results of measurements over 42 subjects are presented.
More cost effective and robust designs of ocular adaptive optics systems could probably be derived from a thorough knowledge of ocular time-varying aberrations. This would in particular benefit to therapeutic systems where the problem of robustness is critical. Unfortunately, high frequency temporal statistical behavior of ocular aberrations remains poorly characterized. We set up an original high resolution custom-built Shack-Hartmann aberrometer running at a frequency of 236Hz additionally featuring pupil tracking and performedmeasurements on a 50-eye population. First analyses are carried out over 20 eyes. Qualitative correlation between dynamic aberrations and saccadic pupil movements is highlighted.
