WP 3.1: Wearable opto-electronic devices for automatic correction of ocular aberrations

Standard spectacles provide good correction for a single optical condition but cannot adapt to changing visual demands or address higher‑order aberrations. This work package develops a compact binocular eyewear that applies electronically controlled optical correction of ocular aberrations dynamically in real time. The project has two complementary aims to deliver both everyday usability and clinical utility: (a) a device intended for everyday use, similar to spectacles but with adaptive, programmable correction; and (b) a device tailored for specific scenarios in research and clinical studies, where rapid reconfiguration and precise control are essential.

The initial part of the project has concentrated on developing a compact low weight device starting from optical design and system integration through bench alignment and laboratory testing. A prototype has been designed, built, optically aligned, and evaluated in the laboratory, demonstrating stable image formation while applying programmable corrections that passive lenses cannot provide (Zheng, Paniagua‑Diaz, Artal: “A compact wearable device for correcting ocular aberrations,” Digital Optical Technologies, SPIE, 2025). Current work focuses on refining optical quality and control electronics, reducing size and weight, and preparing early usability studies to assess comfort, stability, and perceived visual benefits in presbyopia and other aberration profiles.
