Artificial Iris Inside Smart Contacts Corrects Vision Disorders
Artificial Iris Inside Smart Contacts electronic-eye.jpgThe pupil of the eye allows light to reach the retina, and a number of Vision Disorders are related to irregularities in the Iris that surrounds the pupil. People with aniridia, for example, have some or all of the Iris missing, exhibiting a large pupil that results in unfocused vision.

Now, a collaboration between Imec, a Belgian research institution, Ghent University, Spain’s Instituto de Investigaci´on Sanitaria Fundaci´on Jiménez D´iaz, and Holst Centre in The Netherlands, has led to the development of an Artificial Iris integrated Inside a contact lens that can automatically set the proper pupil size to achieve optimal focus and depth of field.

The Artificial Iris sports a liquid crystal display (LCD) that’s composed of concentric circles that can be made transparent or opaque, depending on the desired pupil size. It’s a very low power prototype, allowing it to work for an entire day on a tiny battery.

This way, our approach can surpass current solutions to combat human eye Iris deficiencies. Its beneficial optical effects will be further clinically validated and developed into a medical device.”

A spin-off company has already been formed, called Azalea Vision, to validate and translate the technology into a real medical device.
