Researchers Say New Contact Lenses Let You See in the Dark

Scientists have created adhesive lenses claiming to allow people to see them in the dark with the help of infrared light, a invention that can allow people to see colors again, or spies that transmit secret information through a flash of infrared light.

As detailed in a paper published in the magazine cellThe contacts do not require an external energy source to convert infrared light into a visible light.

Experiments that involve both mice and humans have shown that the lenses allow the wealth to perceive multiple infrared wavelengths – even when the participants close their eyes.

“Our research opens the possibility of non -invasive wearable devices to give people the superior drawing,” said China Xiu, a great author of the University of Science and Technology.

Besides allowing the resolve to see in the dark, contacts can be used to receive data wirelessly.

Xue added: “There are many possible applications immediately for this article.” “For example, the infrared light can be used to transfer information in safety, rescue, encryption, or fight against forgery.”

The invention uses nanoparticles to convert parts of infrared light spectrum, which exceeds what the human eye can discover, into visible wavelengths.

In tests, human participants who wear communications can discover infrared signals similar to MORSE.

“It is completely clear: without contact lenses, the topic cannot see anything, but when they put it, they can see an infrared light flash,” I explained Xue. “We have also found that when the topic closes their eyes, they are more able to receive these palpitations, because the light of infrared rays penetrate the eyelid more effectively than visible light, so there is less interference than visible light.”

Based on their invention, the researchers activated the nanoparticles to make the lengths of different infrared waves appear as different colors, allowing participants to distinguish between them.

As a result, researchers suggest that contact lenses can help people who strengthen colors distinguish between different colors.

Xue said: “By converting red visible light into something like visible green light, this technique can make invisible visible to the blind in color,” Xue said.

Communication is not perfect yet, and you have not been able to capture precise details. It is also a fogy whether the lenses allow the younger to see anything lit by infrared lighting, or simply the light source itself; We have contacted the team with questions, and we will update if we hear.

However, by relying on glasses that sit out of the retina, the team hopes to improve their performance.

Xue said in the statement: “In the future, by working with material scientists and visual experts, we hope to make a more accurate and more accurate communication lens,” Xue said in the statement.
