UAE: Khalifa University researchers develop 3D-printed glasses to treat colour blindness

Team find their spectacles having better optical performance than commercially available options

Researchers at Khalifa University of Science and Technology have developed a new method to manufacture customised glasses using 3D printing that could help people with colour blindness.

Colour Vision Deficiency (CVD) is an inherited ocular disorder that manifests itself in limiting the retina cones’ ability to transmit the whole spectrum of colours. With red-green colour blindness being the most prevalent form of CVD, the most common way of dealing with everyday difficulties is in wearing tinted glasses.

Now, a team of researchers from Khalifa University has developed lenses using transparent resin mixed with two wavelength-filtering dyes to provide a tinting effect. To customize the lenses and make them as similar as possible to commercially available products, the team used two dyes – one blocked the undesired wavelengths for red-green patients, while the other filtered unwanted wavelengths for yellow-blue patients, with volunteers for both groups attesting to the lenses’ efficacy.

Even though glasses based on this method are commercially available at present, they are not comfortable for wearing, nor optimizable. However, the research team developed its own frames for lenses, using 3D printing to optimize them for
