Sounds like smart glasses might do it, if you normally wear glasses. Don't know how visible the display is from the outside, but I imagine if it isn't already they'd eventually be made invisible for privacy.
For now smart glasses all still look strange (e.g. chunky in places normal glasses never are) which acts as a tell and displays remain at least somewhat visible. Hiding screens entirely would likely entail also blocking the light bouncing back from the user’s face in the screen areas which would look odd.
