Scientists Are Working On Bionic Contact Lenses That Stream Real-Time Information In Front Of The Eyes
Scientists announced that aÂ typeÂ of contact lenses thatÂ willÂ project of images in front of the eyesÂ could be soon available to the population.
Bionic contact lenses wereÂ a result ofÂ aÂ collaboration between researchers at the University of Washington and the University of Aalto, Finland. They announced that the lenses have obtained good resultsÂ during animal testing.
Technology will allow those who use contact lenses to read these texts and e-mails that “float” in front of their eyesÂ or to “improve” the 3D images generated by aÂ computer. Scientists workingÂ are now working on aÂ lensÂ designÂ that is safe to be implemented in humans. However, researchers stillÂ face some problems with the power supplyÂ of theÂ device. The prototype developed by researchersÂ is working only whenÂ the wirelessÂ battery is a few centimeters away from the device. Researchers are optimistic that they will be able to improve the device, now that tests on rabbits have shown that the lens does not have dangerousÂ adverse health effects.
Scientists say that these lenses could be used by drivers, allowing them to see their journey and moving speed projected on the car’sÂ windshield. Also, contact lenses could be used for virtual games, and connecting them to the biosensorsÂ inÂ the patient’s body may allow them toÂ display medical data such as blood pressure andÂ blood sugar levels.
Professor BabakÂ Praviz, research team leader, revealed his team’s next goal: “Now we are working to introduce a pre-programmed text in the lens”.
Designing the contact lens, researchers had to use metal layers with a thickness of only a few nanometers, or 1,000 times thinner than a human hair. They also used LEDs with a maximum diameter of 0.3 millimeters.
Researchers from doctor’s PravizÂ team are not the onlyÂ scientists working to develop this typeÂ technology. A Swiss company, Sensimed, already launched on the marketÂ so-called “smart contact lenses”, which uses a chip to monitor intraocular pressure, helping patients suffering from glaucoma.
Arnaud Bertsch, researcher at the ÃcoleÂ PolytechniqueÂ FÃ©dÃ©rale de LausanneÂ and one of the specialists who worked with the SensimedÂ Â company , commented thatÂ five years ago this type of technology seemedÂ detached from SF movies, but can become reality soon. BertschÂ believes that contact lenses, 10 years from nowÂ will be fully computerized displays,Â and huge stepsÂ have been alreadyÂ made in terms of miniaturization.
