I THINK this was a typo. Why would you want to require that authors do something that can be more easily done by users.
I think it was meant to be “usable WITH a reduced field of vision.”
I may be wrong but that is something that SHOULD be there and isnt — and the other makes little sense as far as I can see. (For authors to try to do)
Usable zoomed to 200 % would do that — or moving a mask around the screen.

Whether it's limited field of vision due to a visual condition or because of notification/changes that happen outside of the field or content that must be compared such as table headers and a data cell become more difficult and is something that I believe the LV TF will be looking into.
