Researchers are developing a new display technology that could let folks who wear glasses see a screen clearly without wearing their spectacles.
The technology uses your eyeglass prescription to adjust a filter in front of the display so that you see a sharp image even if you’re normally blind as a bat (or blinder, since bats aren’t actually blind).
Instead of using a lens right in front of your eyes to distort light, the idea is to distort it close to the screen so that folks with impaired eyesight can see a TV, laptop, or tablet screen without prescription lenses.
I imagine this sort of thing doesn’t make a lot of sense for folks like me who can’t see much of anything without glasses. While it’d let me plop down on the couch and watch TV or get some work done on a laptop, the moment I look away from the screen I’ll find myself surrounded by blurry shapes.
It’d also be useless if more than one person wants to look at the same screen.
On the other hand, this could be awesome for people who only need reading glasses.
In fact… I wouldn’t mind using this tech in an eReader. Sometimes it can be hard to concentrate on a book when there are too many other distractions around: literally not being able to focus on anything else could make for an interesting, distraction-free reading experience.
The technology is currently at the early prototype stage: it could be a few years before you see actual screens based on the concept. Researchers at at the University of California, Berkeley, MIT, and Microsoft are working on the idea.
