What sort of extreme environment would exclude other ways of having a hud?
In you eye is an extreme way to do it, considering divers, pilots, drivers, astronauts etc. already wear or are surrounded by equipment this would be more easily integrated into.
If you want to integrate a HUD into a visor you have to figure out a way to make it appear to be farther away than it actually is. With this it looks like those optics could be integrated into the contact lens itself. This actually looks to me like the makings of a fairly robust solution, one that won't require tearing apart existing equipment when something goes wrong with it.
Did you read the article?
The contact lens is just the display, it still requires inductive power and external display source to really do anything. Plenty to "tear apart" and fit into existing equipment.
The lens itself becoming a complete device in its entirety is something I think we are decades, potentially centuries from tech which is that minituarized. Smart rings exist, but they're still orders of magnitude simpler devices.
If you're gonna be wearing a computer and battery on your temple anyway, why is sticking the display in your eyeball, the simplest solution here?
I did read the article. I think having the contact display plus the external unit might prove to be more elegant in implementation than a purpose-built integrated HUD. It doesn't have to be magic tech to compete with reflecting a small LCD off a visor, which takes up space and probably won't work for e.g. underwater welding.
