Can your vision adjust somewhat to the subject...???

I know I probably worded that ass backwards wrong or something but
here is my question. If you are used to working with something, ie...
a 16" monitor as an example.. and you then have to use a much smaller
one... say 9 or 10".

At first, it's like, whoa... very small. But can your eyes, or more
aptly your visual "system" as a whole kinda get used to the smaller
screen to some degree?

Now.. I know your eyes themselves are not going to physically change
but the will the visual system make some adjustments that will enable
you to see the small screen more efficiently?

I know I've read instances where someone loses their sight and they
"claim" that their hearing got better. Whether this is just "mind
over matter" or something that can be measured I have no idea.

So.. in closing, does the mind (or brain) have a major effect on how
well we can see or is most of it because of the refractive errors of
the eyes themselves.

Have a nice night guys.

Thanks Mike... But I do have another question. I do realize that
your visual system cannot modify itself because of conditions.... ie
lighting, subject size etc...

But isn't part of the seeing/reading process sort of like a habit. If
you use the same size screen over and over and over again can't you
get used to it to a degree?

Thanks again
