The research team behind the novel invention said their upconverter can be used in eyeglasses to improve human vision and for augmented reality (AR) applications. Attempts to Convert Infrared to Full Color Face LimitationsIn a published study detailing the novel, full-color IR glasses, the human eye is “inherently blind” to infrared radiation. Other studies have also evaluated wearable lenses with nonlinear upconversion projecting infrared-transformed visible light onto the cornea and photovoltaic nanowire networks. To test their material’s IR upconversion ability, the researchers designed a pair of lightweight (23 grams) semi-transparent wearable eyeglasses. The study “Multispectral infrared-to-full-color upconversion expanding human vision” was published in Science Advances.
