“By converting red visible light into something like green visible light, this technology could make the invisible visible for color blind people,” Xue said.

Despite these promising advances, more work is needed before the lenses see the light of day. Currently, they only pick up light projected from LED sources, which are incredibly bright, so the scientists will need to boost the lenses’ sensitivity to pick up light of lower intensities.

The lenses’ proximity to the retinas also may prevent them from detecting finer details, so the researchers have developed a wearable glass system for viewing objects at higher resolutions.
