Mice are gaining enhanced sight thanks to tellurium mesh implants, offering the tantalizing potential for restoring vision, and yes, even enabling infrared vision. Researchers have successfully tested these retinal implants in macaques, demonstrating they can perceive infrared light alongside their normal vision. While promising, obstacles remain. Fudan University’s team acknowledges the reduced light sensitivity of the tellurium meshes and the surgical risks.The macaques required an adaptation period to interpret the new signals, and shape recognition tests using lasers still need broader real-world daylight validation. Minimizing scarring and improving the retina-implant connection are key priorities. For a fresh perspective, News Directory 3 can share more science breakthroughs.

Retinal Implants Restore Vision, Including Infrared
Updated june 13, 2025
Researchers have successfully tested tellurium meshes in macaques, demonstrating the potential for restoring vision and even enabling infrared perception.The animal model, closely related to humans, showed that implanted macaques could perceive infrared light without changes to their normal vision.
Despite this progress in restoring vision, challenges remain before widespread use of these retinal implants becomes a reality. The Fudan team acknowledges that the tellurium meshes are less sensitive to light than natural photoreceptors, raising questions about their suitability for retinal prostheses. Determining what the macaques actually perceive with the infrared vision implants is challenging, as is understanding how electrical signals translate into perception.
Experiments showed that implanted animals reacted to light,though less effectively than those with healthy vision. An adaptation period was necessary, similar to humans using electrode arrays, where subjects needed to learn the meaning of new signals from their eyes. Shape recognition tests used lasers, making it unclear how the restored vision implant would perform under normal daylight conditions.
The implantation procedure itself carries risks. Eduardo Fernández, a bioengineer, noted that creating a local retinal detachment and incision to insert the implant could lead to fibrosis and scarring, especially in fragile retinas. However, Fernández still considers the implants promising. The Fudan team is focusing on long-term safety assessments in primates and improving the connection between the retina and the implant.
What’s next
Future research will concentrate on refining the sensitivity of the tellurium meshes and minimizing surgical risks to enhance the viability of retinal implants for widespread use.
