The Private Eye uses persistence of vision to create a 720x280 pixel monochrome screen. A vibrating mirror scans a column of 280 LEDs across the user’s eye, and the LEDs turn on and off rapidly to form each pixel of the screen. The display is surprisingly sharp, and it may be focused at different distances, relieving eyestrain. It is low power (0.5 W), provides a 22-degree field of view, and weighs 71 g without the head mount. While an opaque display might cover one eye, the user has the illusion that the display is see-through because the human visual system combines and shares the images received from both eyes.
