Scientists Develop Contact Lenses to See Invisible Light

A team of scientists in China has recently made a groundbreaking discovery in the field of vision technology. They have successfully developed contact lenses that enable wearers to see light that is normally invisible to the human eye. What’s even more fascinating is that these lenses work even better when your eyes are closed, and future versions could potentially help individuals with color blindness.

The human eye is capable of perceiving a limited range of colors, typically between wavelengths of about 400 and 700 nanometers. This range is commonly referred to as the ‘visible’ spectrum, although some animals can see beyond these boundaries.

In a recent study, researchers have extended human vision into the infrared spectrum, allowing individuals to see light between 800 and 1,600 nanometers in length. This range, known as infrared, is typically invisible to the naked eye. The secret lies in wearing contact lenses embedded with nanoparticles that convert infrared wavelengths into visible light.

These specialized lenses do not interfere with a wearer’s ability to see visible light; instead, they add infrared sources to the visual mix. Test subjects were able to identify flashing signals emitted by infrared LEDs and determine the direction from which the light was originating.

According to neuroscientist Tian Xue from the University of Science and Technology of China, individuals wearing these contact lenses could see the flickering of infrared light clearly, even with their eyes closed. In fact, the lenses seemed to function even better when the eyes were shut, as infrared light penetrates deeper into the skin than visible light, allowing the eyelids to filter out intense glare.

It’s important to note that wearers are not perceiving new colors with these lenses. Instead, the nanoparticles absorb infrared light and convert it into familiar visible colors. This technology could potentially provide new insights into our surroundings, with potential applications in security and encryption.

In further experiments, the researchers demonstrated that an enhanced version of the contact lenses could enable users to differentiate between various parts of the infrared spectrum. By color-coding the infrared wavelengths, light at 808 nanometers appeared green, 980 nanometers was blue, and 1,532 nanometers appeared red.

The team envisions adapting this technology to assist individuals with color blindness in perceiving things they wouldn’t typically see. While it won’t restore missing colors, it can convert those wavelengths into ones detectable by the individual’s eye.

One drawback of contact lenses is that they are in close proximity to the retina, causing the converted light to scatter and result in slightly blurry vision. Wearable glasses incorporating the same nanoparticles offer a higher resolution for perceiving infrared light.

In subsequent tests with these glasses, the researchers demonstrated how infrared light reflecting off objects can encode information that is invisible to the naked eye. Just as objects appear in specific colors due to visible light patterns, the same principle applies to infrared light, which is typically unseen.

During tests, participants wearing the glasses observed that seemingly bland black or white letters transformed into vibrant colors when viewed through the specialized lenses. This transformation occurred because the glasses converted the infrared wavelengths bouncing off the letters into specific visible colors.

While the idea of detecting heat signatures in the dark may sound intriguing, the current technology is limited to picking up infrared light from strong LED sources. The research team aims to enhance the sensitivity of the nanoparticles in future studies.

The findings of this study were published in the journal Cell.
