Color blindness is the absence or deficiency of a special pigment molecule in the visual center of a living being. In both cases, people are not able to distinguish between different colors.
Three types of cones exist on the retina of the eye; everyone can distinguish between blue, green and red light. The ability to perceive the full range of colors is only achievable when all three cones work together, but color vision deficiency (CVD), an inherited eye disease, limits this ability.
Most people use handheld devices to see colors
The most common type of CVD is red-green color blindness, and most patients use handheld devices to manage the challenges they face during daily tasks. The most popular type of laptop is tinted glass.
In this regard, Dr. Haider Butt, Associate Professor of Mechanical Engineering, Dr. Fahad Alam, Postdoctoral Fellow, Dr. Mohamed Elsherif, Postdoctoral Fellow, and Ahmed Salih have exerted all their efforts to facilitate the lives of color blind people.
“Customizing patient-specific eyewear for CVDs remains a challenge, even though research has greatly improved the properties and materials of commercially available CVD garments,” Dr. Butt said.
The two dyes used to make the new 3D glasses
As noted in the statement, a type of CVD known as deuteranomaly that primarily affects men causes the photoreceptor responsible for detecting green light to react to red light. Red-tinted glasses can help with this by improving color visibility.
Some of the wavelengths between green and red that confuse photoreceptors can be absorbed and filtered out by certain dyes. The brain receives a sharper signal to help differentiate between problematic colors when there is less color overlap. The other CVD types can also be included in this idea. So the team used two dyes.
