My experience is that it helps with being able to look at screens, but not that it is better than not looking at screens while riding. I needed to occasionally leave the screen and close my eyes or look outside (depending position in the vehicle) for a bit to calm down. But otherwise I cannot look at screens on rides for more than a few minutes, so it is better in this sense.

So yeah, as somebody with (moderate) motion sickness, this advise resonates with me to some extent.
