    Around 100 million people around the world suffer from visual disorders that cannot be fully corrected with eyeglasses or contact lenses.

    Some of them are produced by high order aberrations (HOA) of the eye. These can have a significant effect on the quality of vision, producing disturbing glares, halos and trouble seeing in dim light, causing an overall reduction in patients’ independence and quality of life. There are currently no adequate treatments or devices to correct these optical defects of the eye.

    The project aims to develop the first smart glasses to correct HOAs.The researchers have developed a device based on spatial light modulators (devices used to modulate amplitude and phase of light waves) and powered by real-time pupil tracking. This approach can also help correct refractive errors and presbyopia, which affect more than 1.8 billion people worldwide. With the support of CaixaResearch, they will miniaturize their prototype and enhance computing performance, with the aim to reach the market within 4 years.
