It is currently used to monitor blood sugar levels in diabetic patients and to look for glaucoma (so the "picture" it displays does not have special rice grains).

Although this screen is a few millimeters away from your retina, you can still see a clear picture as long as the focus is chosen correctly. When the LED effect is turned off, it is a normal contact lens. And its power and data will be transmitted wirelessly.
By the way, this thing is designed to be a daily throw.
