New Display Technology Corrects For Vision Defects 28
rtoz (2530056) writes Researchers at the MIT Media Lab have developed a new display technology that automatically corrects for vision defects without requiring glasses or contact lenses. This 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. The display is a variation on a glasses-free 3-D technology: a 3-D display projects slightly different images to the viewer's left and right eyes. Similarly, this vision-correcting display projects slightly different images to different parts of the viewer's pupil.

I barely need glasses to drive, for distance. I can read books held in my hands without glasses. Laptops and desktops are every so slightly too far away to usually be able to do that. I would love to be able to ditch the glasses when at my desk at work.

I would love this for my phone.
I am nearsighted. I have no problem reading my phone but I have problems seeing things that are far away. So I wear my glasses when I drive, bike, or go to movies. It's not too bad--I have driven without my glasses by mistake before with no major collisions. I've seen movies without my glasses and I can tell what's happening on the screen. But having glasses on definitely helps.
So if I'm nearsighted, why would I need this?
Because, with my glasses on, I have a hard time fo

It won't ajust automaticaly. According to the video the solution has a hardware component and a software component. The software is configurable and can be setup to different prescriptions (or the lack off), but the hardware (a lensing film to be placed on top of the screen) is specific to one prescription.
But, even withtout the flexibility to ajust to other people's sights, I think this technology has a huge potential in very personal devices like mobile phones. I believe many people would gladly give up t

What about people who need "reading glasses". Those people navigate the rest of reality very well without their glasses (actually puting their glasses limits their reality navigation ability), those need their glasses only to read and I bet many would apreciate a phone that you can just pull out of the pocket and read instead of also pulling the glasses from the other pocket.

This would be great for HMD's too. You could design them to be worn without having to accommodate glasses.

Yep. I have different degrees of long-sightedness in each eye plus varying amounts of astigmatism. How is a gadget like this going to show each eye what it needs?
Since I'm already wearing glasses to drive with, my eyes would have to adapt again to view whatever this gadget is displaying. They're already doing that without spending money on the gadget. FAIL.

I'm still not quite sure how it is they've solved this issue they claim, however the ability to selectively transmit information to make the image seem to appear between the eye and the screen is the wrong solution. For those over 40, the problem isn't moving the screen closer but rather needing it further away. I have this happen if I put my phone too close in the car - I can't effectively see the GPS prompts or warnings without a second or so of re-focusing effort, and even then it's a challenge with my

Puting your glasses also don't change the distance from your eyes to the objects. Instead the lenses bend light so it is indistinguishble from light coming from another distance, and that is exactly what this solution does, in simple terms it is like putting the glasses on the device instead of on your face.

Slashdot reminds me of just how ignorant and yet unjustifiably arrogant and egotistical most tech nerds are. It sickens me to see so many people without the slightest degree of empathy or ability to understand that their limited experience is not (can not) be the be-all-end-all of reality.
There are a large variety of vision problems. Many make it difficult to change focus quickly or at all. How something as basic as this can escape so many people would be funny if it weren't so indicative of a general trend
