By Sharon GaudinJuly 31, 2014 06:43 AM ET Computerworld - What would it be like if you didn't need your eyeglasses to clearly see your laptop screen or a text message on your smartphone?
Scientists at the University of California Berkeley are working on computer screens that would adjust their images to accommodate individual user's visual needs. Think of it as a display that wears the glasses so users don't have to.
"For people with just near sightedness or far sightedness, life isn't so bad," said Fu-Chung Huang, the lead author of the research paper on the display project at Berkeley. "But as you get older, your lenses lose elasticity and you cannot read things close to you, like a cell phone or tablet. You need another pair of reading glasses, which can be quite inconvenient.
 
The researchers have been working on the technology for three years.

If a user who needs one pair of glasses to see things at a distance and another pair for reading, would not need to put on reading glasses to read her emails or Facebook posts if the display could adjust itself for her near-vision needs.
The displays, according to Berkeley, also could be used for people whose vision cannot be corrected with eyeglasses or contacts.
