Abstract
The virtual vision correction technique described herein pertains to a technique for determining a user's vision characteristics and/or adjusting a display to a user's vision characteristics. The virtual vision correction technique described herein provides vision correction for people with vision problems by making the video displayed adapt to the person's vision correction needs. In one embodiment of the technique, the user can state their vision prescription needs and the video displayed is processed to appear “20/20” to that person. Alternatively, the video display, for example, video display glasses, can “auto-tune” a representative image (such as an eye chart) to determine the appropriate video processing for that person.
