I can switch the camera in my car to replace the normal mirror. This is useful when the trunk is full. I hate it, though, because it forces your eyes to quickly and repeatedly adapt to short vision (the image is close to you), then again on the road etc. There is no such a problem with the normal mirror which shows objects far away so you you don't need to adapt when switching between forward and back view

Reading https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2908311/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2908311/, it can take half a second (for the oldest age group, in the dark) before an eye even starts to accommodate and, if I’m interpreting RTI correctly, easily another half a second to accommodate. Makes me wonder how sharp an image one needs to see in the rear view mirror to drive. Or do drivers really look to such a screen for over a second while driving? And of course, getting rid of the front window, too, would get rid of the accommodation issue, but I do not see that being accepted by car drivers soon.

  I would be fine with switching to a closed cockpit, provided I get augmented information, removal of distractions etc. We are I guess 30 years short of such features so that driving with such a cockpit is safer and more efficient

> it forces your eyes to quickly and repeatedly adapt to short vision Sounds like a big nono for "older" people. I'm having difficulty focusing on the dashboard nowadays. Progressive glasses could fix it, but the short distance area is at the bottom, so you would have to tilt your head alot to see the mirror.

I bought one of those well reviewed mirror dash cameras and it replaced the center rear view mirror. I hated it and returned it because this extra visual burden and couldn't understand why anyone liked these. When backing up out of a parking space I much prefer the turnaround method since I lose all my periphery vision that keeps from backing up into the path of other vehicles or people, etc. My back up camera even has a warning for that basically saying "be aware of your surroundings while backing up, because this tiny cone of vision on the screen definitely won't help you with that". Of course modern cars are so high up I can't see anything directly behind me without the camera.

  I use the side mirrors and the camera to park. Taken how our parking spaces are narrow in France, this was for me the best combination.

Is it physically possible to mitigate this issue by placing some sort of lens on the screen, so you would need to actually focus "to far" in order to see it?
