The light contains separate particles that spread in waves. Wavelength determines the color and energy of light.
The human eye can only consider a small portion of this spectrum, the range between about 400 and 700 nanometers.
Because of that, we humans are inaccessible to see infrared range, up to one millimeter of 750 nanometers of its long wavelength.
So to see infrared lights, we now need a comparatively huge night of the night-vision goggles or night-vision devices until our energy.
Infrared contact lens from China
Researchers at the University of Science and Technology at Hefei, Eastern China have now developed a contact lens that converts infrared light into visible light, which enables humans to see in the dark.
The Yukian MA and his team have paired the traditional soft contact lens with 45 nanometer particles consisting of gold, sodium gadolinium fluoride, yaterbium, and arbium ions.
Upconvervont Montact Lens (UCLS) Infrared Lite appears with wavelengths below 800 and 1.600 nanometers, the team has written in scientific magazine Chamber,
The nanops enriched long infrared light waves with energy. In doing so, they change the three primary colors infrared light interactions, showing them to the human eye.
One defect is that the resulting images are very blurred because the nanops up in the lenses scattered the light, which was able to partially compensate by adding the team alpine.
However, infrared contact lenses are still not as powerful as night vision goggles, which increase weak infrared signals, causing them to appear.
Even more better sight with eyes stopped
The team first injected the nanops up into the retina of mice and their behns showed that they could see in the dark.
Newly developed contact lenses are very practical because they are not non-invasive-econning that are no injections in our retina.
In trials, humans were able to identify patterns, letters and shining infrared signs in the dark. And infrared lenses work even better with closed eyes, as infrared lights can not easily disturb the eyelids and image generations with normal visible light.
Animal infrared capabilities
Many animal species are able to see infrared light, which are extremely helpful when hunting in the dark. They do not see infrared light in the sense of human vision as “light”. Instead they consider the heat radiation emitted by items.
It helps in searching some cold-blue reptiles as snakes (rattlesnakes and pit wipers), some fish (paranhas and cichlids), some amphibians (bulfrogs) and some blood-sucking insects (mosquitoes and bugs).
Hot-rich animals-like humans, in the form of infrared lights in the form of other mammals and birds that their eyes do not have proper receptors and their body’s own radiation will also interfere with the perception of infrared light.
Big question about benefits
Chinese is attractive as innovation, it remains to be seen how it can be used in everyday life.
According to developers, lenses can be used in surgical processes, in the field of encryption or cryptography, or for fake protection.
This is because infrared light is one that appears on documents invisible features or inks, for example.
The lens can be used to protect people in a state of poor visibility as they appear to heat emitting objects. However, many critics have this doubt, as the night vision device is very easy to use, and therefore important is more powerful.
