American researchers at MIT suggest that screens will soon be able to adapt to sight, and thus correct vision problems depending on the user. The end of prescription glasses?
“Wait before putting on the film, I’ll get my glasses” is a phrase that may soon be a thing of the past. Indeed, American researchers of the famous MIT (Massachusetts Institute of Technology) predict that new television screens will replace prescription glasses soon.
A light filter placed in front of the screen
In a report published in the MIT Technology Review, these scientists suggest that people who have to wear glasses to watch their computer screen or television will soon be able to put them away in their cases for good, because the screens could adapt to the sight and thus correct the problems of vision according to the user. How? ‘Or’ What ?
By transforming prescription data for eyeglasses into computer algorithms. Then they used a light filter placed in front of the screen.
As a result, the algorithm changed the brightness of each pixel on the screen, creating a sharper image when it reached the retina.
The screen plays its role of regulator
To achieve this, the researchers developed this technology in a study in which they began by choosing images of hot air balloons with very vivid colors before distorting them using different algorithms.
But people who suffered from minor vision problems did not find these images distorted. On the contrary, they were perfectly clear on their iPod Touch equipped with the previously mentioned plastic light filter. Logical, because according to them, it is the screen that regulates the way in which each ray of light emanates from the display.
A solution for more serious eye disorders
Subsequently, the researchers also tested their technology using a Canon digital SLR camera and came up with an equally sharp image without affecting the contrast. Although this technology could prove promising for people with minor vision disorders, the professor in charge of this study and his team hope that it can also offer solutions for people with more serious eye disorders who cannot be corrected with glasses or lenses.
The only downside in this story, with a major obstacle to the development of this technology. According to the designers, the technology will not be able to be adapted so that several people can watch the same screen simultaneously.
One of the co-authors, however, believes that high resolution could facilitate simultaneous viewing, but more work on the subject is still needed before large-scale commercialization, he concludes.
