UFRGS researchers in partnership with MIT Media Lab and the University of Purdue have created a new kind of display that compensate for vision problems. The invention was validated with nearsightedness, farsightedness, astigmatism, age-related vision loss, other higher-order aberrations and cataracts. This is the first display that removes the need of eyeglasses.
This new system, called Tailored Displays, is a project of the computer graphics group at UFRGS. The hardware is the same of glasses-free 3D displays (dual stack of LCDs, like the one found on the Nitendo 3DS and some phones), but in higher resolution. To use it, simply insert your prescription data and take out your glasses. The device uses measurements of refractive error from NETRA and CATRA to distort the image being displayed, compensating for refractive errors and deviating from cataract sites. The display works in real-time and can be built with currently available LCDs.
The new display is ideal for daily tasks where using eyeglasses are unfeasible or inconvenient (e.g., on head-mounted displays, e-readers, as well as for games); when a multi-focus function is required but undoable (e.g., driving for farsighted individuals, checking a portable device while doing physical activities for presbyopic); or for correcting the visual distortions produced by high-order aberrations that mere eyeglasses are not able to.

Figure 1: Comparison of the view of a presbyopic individual (need strong reading glasses) in a regular display (top-left) and a tailored display (bottom-right). These are actual images of our prototypes.
Figure 2: Demonstration on how the letter G (a) is projected on the retina of a 2D-coma, +5D-myopia (c), and cataract affected (d) subject. The letter G is placed at many depths from the subject's eye (16cm < j < 25cm). (b) shows how the image reaches the subject’s retina. (e) and (f) shows our computations for the image that will be displayed by the device.
