These 3D printed glasses could be the cure for color blind people, research shows

The 3D printing of glasses.

Color blindness is the absence or deficiency of a special pigment molecule in the visual center of a living thing. In either scenario, people are not able to distinguish various colors.

Three cone types exist on the eye’s retina; each can distinguish between blue, green, and red light. The ability to perceive the whole range of colors is achievable only when all three cones work together, but color vision deficiency (CVD), a hereditary eye illness, restricts this capacity.

Most people use wearables to see colors

The most common type of CVD is red-green color blindness, and most patients use wearables to manage the challenges they have doing daily chores. The most popular type of wearable 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 put all their efforts into making color blind people’s life much easier.

“Patient-specific customization of glasses for CVD remains a challenge, even though research has significantly advanced the properties and materials of CVD wearables available on the market,” Dr. Butt said.

The two dyes used to build the novel 3D glasses

As said in the statement, a type of CVD known as deuteranomaly and that primarily affects men causes the photoreceptor in charge of detecting green light to react to red light. Red-tinted glasses can help with this by enhancing the colors’ visibility.

Some of the wavelengths between green and red that confuse the photoreceptors can be absorbed and filtered out by certain dyes. The brain receives a sharper signal to aid in differentiating between the problematic colors when there is less color overlap. The other types of CVD can also be included in this idea. Thus, the team used two dyes.
