A new generation of contact lenses is being developed by researchers at Washington University, which could one day project up-to-date medical information in front of the wearer’s eyes.
The scientists, working with colleagues at Aalto University in Finland, have adapted lenses to shorten the focal distance so wearers can see images at short distance. They envisage hundreds more pixels could be embedded in the flexible lens to produce complex holographic images.
Initial safety tests of the lenses in rabbits have gone well with no side effects, and the researchers say it is a safe and feasible project.
However, currently their crude prototype device can only work if it is within centimetres of the wireless battery. Lead researcher Professor Babak Praviz said: "Our next goal is to incorporate some predetermined text in the contact lens."
If the technology proves successful, wearers could one day read floating tests and emails in front of their eyes.
This could be an exciting development for the medical industry, since the lenses could provide up to date medical information like blood sugar levels by linking to biosensors in the wearer’s body.
Scientists have already developed a smart contact lens called Triggerfish that uses inbuilt computer technology to monitor pressure inside the eye to diagnose and monitor the eye condition glaucoma. Triggerfish is currently being used in private hospital the London Eye Hospital.
Patients with private medical insurance have access to revolutionary treatments like Triggerfish. If this new lens proves useful in the medical world, they might also be some of the first to try it out.
