Many of us would have to face that embarrassing situation where we had to say “Man, I forgot my glasses. Would you please help me read what’s on the screen?” or lamented that “I am not eligible for that job because of my eyesight”. In this digital era, a digital display is the first thing we look-at once we wake up, the last thing we see before we sleep, and something we stare at most of the time in-between. Though it is a necessity, it is not easy for many with a condition with their eyesight. All the screens in this world may not adjust as per your eyesight, so we use a pair of lenses before our eyes to adjust our self. After all “I can’t change the direction of the wind, but I can adjust my sails to always reach my destination”
However, that situation is about to change. Clever Brains of MIT and Berkeley have devised a display technology that makes the screens adjust as per your eyesight so that you see a clear image without the need of wearing glasses. Wouldn’t it be great if you can use your devices without the hassle of your spectacles?
In this digital era, where displays are ubiquitous, the ability to interact with displays is an everyday necessity. In some cases, it becomes part of your job and being unable to do so may cost you a living. Especially when it becomes difficult to have a contact lens that fits, say, for people with higher order aberrations and thus irregularities in the shape of the cornea. The research team is positive and passionate about the possibility that this research could help millions of people with eyesight disorder and can increase employability.
How it Works?
The technology works using a combination of software and hardware. The software alters the image based on the viewer’s eyesight condition where as the hardware is a specialized filter set in front of the display. The technology predicts how the users’ eyes will distort whatever is on screen and correct it beforehand by altering the light from each individual pixel and passes it through a small hole in the filter, so when each ray of light hits the cornea of the user it accounts for the distortion and creates a sharper image on the retina.
