    Portable device for presbyopia correction with optoelectronic lenses driven by pupil response
    (Springer Nature, 2020-11-20) Mompeán, J.; Aragón, J.L.; Artal, P.; Aragón, J.L.; Artal, P.; Ingeniería y Tecnología de Computadores
    A novel portable device has been developed and built to dynamically, and automatically, correct presbyopia by means of a couple of opto-electronics lenses driven by pupil tracking. The system is completely portable providing with a high range of defocus correction up to 10 D. The glasses are controlled and powered by a smartphone. To achieve a truly real-time response, image processing algorithms have been implemented in OpenCL and ran on the GPU of the smartphone. To validate the system, different visual experiments were carried out in presbyopic subjects. Visual acuity was maintained nearly constant for a range of distances from 5 m to 20 cm.
