In a #ScienceFiction story I once came up with, people wore contact lenses that acted like projectors/computer screens/VR glasses. They would wear nail polish or rings (for folks who preferred more easily removable tech) that would sense finger movements, so the user could type or manipulate the virtual world (as seen in their contact lenses). Sound and music were from earrings and jewelry around the neck (some people used bone-conduction sound in necklaces).
The contact lenses would be worn all the time, so you didn't have to take them on and off like VR goggles, and also allowed the user to see the real world-- they could be prescription, if the user needed contacts to see 20/20 anyway.
Admittedly, the ideas are #SciFi. But SciFi has often predicted future reality. I can see people wanting to use tech this way.
