Quedtion about playstation vr from a legally blind gamer

Hi,

I'm just curious if retailers will have a demo unit like they do the vita and ps4?

I'm really interstellar in the vr but with being legally blind I worry about spending the money to only find out I can't really use it.  I current use a 60 ich tv but sit closer than most probably would

Are there accessibility features?  

How big does it seem to the players? 

How big is text if any in most games?

I gave a vita and played the crap out of my psp the only ussues with those was the text in some games.

Thanks

Bryce
