This is an amazing invention based on a reversed way of thinking.
Massachusetts Institute of Technology developed a digital monitor which displays an image automatically adjusted for a viewer who has vision defects.
MIT News: Vision-correcting displays
The principle of the monitor is as same as glasses. These two monitor displays each vision which is simulated to be compounded correctly on the retinas of the viewer. Recent development of the rapid calculation of computing and digital monitors with extremely high resolution have enabled such architecture. Different from glasses, this monitor can be adapted to several persons sequentially.
Glasses are essential for our daily life. However, we also have to gaze at a monitor for a long time in both private life and at work. This invention will release us from continuous equipment of glasses during watching the monitor. I think it is a fantastic perspective.
