Smartphone displays that will eliminate the need to see through prescription glasses or contact lenses, is possible through a new technology, claims a team of researchers at the Massachusetts Institute of Technology.
The new display would be able to project sharp images to give the user a clearer image even without them using their eyeglasses.
Brian Barsky, Professor of Computer science and vision science at the University of California said that this could be the solution for people with complex vision problems that cannot be corrected by prescription lenses. Some eye conditions such as the high order aberrations make it impossible to make lenses that will help them as the cornea of the eye has irregularities in such cases.
The display developed with the technology invented by the team could help even people affected by such conditions. People who can’t take up jobs involving looking at a computer screen or other digital devices can also be benefit from the technology.
The prototype has a pinhole screen placed between two sheets of clear plastic with the pinholes measuring 75 micrometers and spaced 390 micrometers from one another. The tool works with an algorithm, which determines the course of action based on the light rays emerging from the screen of every pixel and is adjusted to suit the user’s degree of vision.
The deconvolution process employed lets the light rays pass through the pinholes and makes the images sharper than normal making it clearly visible for the user.
Lead author of the study, Fu-Chung said that the prototype can be developed into a thin screen protector which can be applied on the screens of digital devices and with the help of eye-tracking technology, the displays can adapt to the head position of the user.
