This company wants to give you smart contact lenses that could tell you if you really should have that second cup of coffee

Mobile World Congress 2024 saw its share of phones, laptops, and wearables, but bio-enhancement devices were few and far between. They were not, however, absent. Xpanceo unveiled this week four different smart contact lens prototypes that may someday become real products that you put in your eyes.

Smart contact lenses may be the holy grail of wearables. I blame The Six Million Dollar Man, a 1970s-era TV show featuring a biomechanically-enhanced former astronaut who had, among other things, a bionic eye that let him zoom in on and assess targets (there was even a data readout). That, I assume, is the dream of the smart contact lens, a wearable tech category that has thus far failed to get off the ground.
