Would be 'a thing' :

• A usable and reliable AR lense exist that most people can wear as contact lense to experience AR , even with a bad autonomy.

• A convicing prototype, even expensive, featuring all aspect of reasonnable quality AR, tried by trustable sources would count.

• A valid AR lense would feature at least a functionnal overlay display with a minimum of 1Hz refresh rate, some interactions like navigating a menu, allow movement of the user during use, keep track of some elements of surrounding.

• Spacial mapping capability of the contact lense can be helped by external device.

• General public must be at least aware of it.

Would not be 'a thing' :

• Barely usable lense or prototype would not count.

• Creating heavy motion sickness to a majority of people would not count.

• Creating systematic pain to average healthy user would not count.

• Creating constant heavy disorientation or preventing space awarness would not count.

• An hypothetical leaked military secret would not count.
