Chinese scientists have created new infrared contact lenses that expand the capabilities of the human eye. According to research published in "Cell" magazine, these lenses allow seeing even in darkness.
The scientific team succeeded in converting previously invisible infrared rays into visible light by combining nanoparticles with contact lenses. With the help of this technology, a person can perceive rays in the range of 800-1600 nanometers.
The experiment was initially conducted on mice: they could move even in darkness after nanoparticles were injected into the retina. Later, the lenses were adapted for the human eye. Those who participated in the tests were able to recognize light signals even in the dark with closed eyes.
According to scientists, these lenses can be of great benefit in the areas of rescue services, military operations, or night surveillance. They do not require an external power source and are worn like regular contact lenses.
However, the research is still in its infancy. Lenses can sometimes blur the image or work inefficiently in weak light sources. Therefore, scientists are working on further improving the technology.
Experts note that this discovery marks the beginning of a new era in human vision, and in the near future, "night vision lenses" will become a common reality in our lives.
