As shown in the crash video, this caused the nodding joint of the dummy’s upper neck to break, and the head was detached from the body. Although this isn’t likely to happen to a human driver, it illustrates the extreme forces the dummy absorbed.

Here, PM_ME_UR_LIDAR uses the pronoun "their" referring to Ouster, the lidar company. But PM_ME_UR_LIDAR was working at Ouster, Inc. at the time the comment was written.
Note that if you use a projector or watch TV a lot in the dark, you won't get myopia/nearsightedness. AR glasses and VR headsets are also better w.r.t. myopia. It's worth switching to alternatives to computer monitors when using devices for long periods of time.
Smartphones should really be used for looking up information quickly at a glance. When you need to do something for longer periods of time, you should use different devices. To prevent nearsightedness/myopia, you can use AR glasses, VR headsets, projectors, TVs, etc. instead of using monitors or reading physical books. The aforementioned devices keep your eyes relaxed (accommodation-wise) over long periods of time.
It could be both. And focus distance may matter. Like, books may also cause myopia. Reading books outdoors may be a bit better than reading books indoors. Using screens at a distance could also be benign.
Not everyone gets motion sickness though. I can use my VR headset for hours without discomfort from VAC.
From that publication:
The results of the study indicated that the visual acuity of employees who work with data glasses generally did not change over the course of a shift and over a period of six months. Nevertheless, there were groups that had an increased chance of deterioration. Eye strain was frequently reported after working with the data glasses.
Our study pointed out that employees aged 40 years and older are at risk for deteriorations of visual acuity, which is consistent with the findings of Yeow et al. (1991), who examined computer users.
