A latest method has been invented through which eyes testing can be done with the help of a mobile phone. For this, the user will have to simply download software, install in any mobile and get their eyes checked. This latest technology called NETRA (Near to Eye tool for refractive assessment) has a viewer that fits over the screen of the mobile and has software which runs of the cell phone. The device NETRA is designed by Massachusetts Institute of Technology (MIT). The invention of this device has been made possible with the help of MIT’s Media Lab Associate Indian born Professor called Ramesh Raskar, visting professor Manuel Oliveira, students Ankit Mohan and Vitor Pamplona and a post doctoral research associate.
In order to check the eyesight, the user will have to attach the plastic to the screen of the mobile phone and then look into the small lens. The arrow keys in the phone have to be then pressed till the set of parallel green and red lines overlap. This process is to be repeated 8 different times for each of the eye and within 2 minutes the software will provide the prescription data.
Great work...
