Colors can be easily differentiated using the naked eye is what is normally thought. However, there is a certain range of wavelength that is difficult to differentiate by the naked eyes. In order to help differentiate the colors that are slightly different or camouflaged, the scientists have come up with a new pair of spectacles that can help spot the distinct colors.
A research team from the University of Wisconsin-Madison has developed a pair of spectacles that has the capability to improve the user’s color vision by differentiating between the metamers of those colors that look similar but have only a slight difference in their wavelengths.
The humans have three types of cone cells that help them react to short (blue), medium (green), and long (red) wavelengths, which in turn help their vision differentiate colors easily and with accuracy. The researchers are putting this concept into being and trying to trick the human eyes and also help them understand colors. Though humans belong to the group of trichromatics, there are certain cases where they belong to the tetrachromats.
The spectacles are made of two color filters, that is, one for each eye that can help distinguish the parts of the blue spectrum of light. Using this glass, the slightest of the difference could be observed. When the metamers were portrayed on any screen or surroundings, they tend to look exactly the same but when seen through the glasses, the distinction could be made out.
Earlier, the concept of filters had been tried but the use of different filters for both the eyes made its usage difficult. Hence, the use of subtle difference filters has helped improve the color vision of the humans. Currently, the researchers have explored the blue light spectrum and intend to look into the green light spectrum next.
These glasses can prove to be exciting when worn during an evening walk. It can help see the world in a more colorful way.
