It’s the latter that piqued my interest, after hearing Jaguar Land Rover has embarked on a research project to discover whether the lens can improve car HUDs and, with it, road safety. Dr Ash Saulsbury, former technology VP at Microsoft and former Meta AR boss, joined late last year as chair, around the same time that the startup secured a $5.3m funding round. I don’t wear glasses, so the first demonstration—viewing digital text beamed from a laptop to an augmented reality headset—didn’t seem overly impressive. The augmented half of each line was a blurred mess. I experimented with focusing first on my hand just a few inches from my face, then on the other side of the room, yet the augmented text stayed in focus.
