Who hasn’t dreamed of having heads-up display screens directly embedded into their eyes? I guess years of playing Cyberpunk 2020 and reading science-fiction novels have made this a fixture in most settings. While it won’t make readable contact lens displays feasible any time soon, it looks like scientists have actually been able to make contact lenses with embedded LCDs.
Belgian researchers at IMEC were able to create an LCD-embedded contact lens in a working prototype. This LCD display is curved so that it fits the eye. For now, the lens can display rudimentary monochrome graphics, and their images can only be viewed by others, not by the wearer due to the eyes inability to focus on objects so close. However, there are applications where these could be useful. They could work like sunglasses by automatically darkening, as cosmetic enhancements by changing colors, or as an artificial iris.
Now, if they could only figure out the focusing issue, we could someday be walking around like human Terminators.
