Israeli researchers invent contact lenses to correct colour blindness

Israeli researchers from Tel Aviv University have found a way to correct one of the most common forms of colour blindness, deuteranopia, (or red-green colour blindness).

They have done so by incorporating ultra-thin optical devices known as metasurfaces with the type of contact lenses you can buy off the shelf.

Test subjects reported that their colour perception improved to a factor of 10 with use of the customisable contact lenses.

This marks the first time tiny optical devices have successfully been fused to curved surfaces.

Although clinical testing is required before the contact lenses can be marketed, the researchers believe that manufacturers could embed the metasurface during the moulding stage of contact lens fabrication or thermally fuse them to a rigid contact lens.

The team plan to keep studying and improving their unique metasurface transfer process and see if they can expand this technology for helping with different types of colour blindness.
