Vision problems are a result of the eye's lens being unable to focus
an image on the retina.
There is nothing that can be done about that other than to put a
corrective lens (called glasses) in the system.
Arm waving about "apparent distance" is babble unless there is a
separate lens involved.

"Near-sighted" refers to the ocular defect where there is trouble in
distance viewing, however I think what the earlier poster was pointing
out is that having a 3D model would be no different than the normal
flat screen, "2D screen" that we have of today. For example, using a
3D model to mitigate the effect of distance bluriness would be no more
effective than simply bringing one's face closer to the conventional
type screen in order to see objects clearly. The thing I am curious
about here though is precisely what kind of 3D technology the original
poster was hypothesizing should be utilized for this idea?

Beg pardon? I am "nearsighted". Guess what the term means.

I don't think so... People who need glasses don't have a problem seeing
things at the wrong distance - so correcting the apparent distance using a
3D effect doesn't help.

Imagine using a laptop without having to wear corrective
eyeglasses.
I know that 3D displays exist that don't require special glasses.
So maybe this is possible as well?
