Are you squinting at your phone? I am, and I’m tired of it. Fortunately new technology could solve the issue not just with bigger fonts, but with an overlay screen that could tailor every device to your own individual optical prescription.
MIT Media Laboratory and the University of California at Berkeley have developed a new display technology that automatically corrects for vision defects — no glasses (or contact lenses) required, MIT reports. “The technique could lead to dashboard-mounted GPS displays that farsighted drivers can consult without putting their glasses on, or electronic readers that eliminate the need for reading glasses, among other applications.”
The solution “basically puts the glasses on the display, rather than on your head,” the chief scientist behind it says. “It will not be able to help you see the rest of the world more sharply, but today, we spend a huge portion of our time interacting with the digital world.”
The display is a variation on a glasses-free 3D technology, and projects slightly different images to different parts of the viewer’s pupil. “A vision defect is a mismatch between the eye’s focal distance — the range at which it can actually bring objects into focus — and the distance of the object it’s trying to focus on,” MIT says. “Essentially, the new display simulates an image at the correct focal distance — somewhere between the display and the viewer’s eye.”
