Section 12 of the Copyright Act allows certain acts of reproduction to be done without permission. 'Fair Dealing' in Section 12, allows reproduction for the following purposes:-
The fair use / dealing copyright section allows a user to copy, for their own study or research or private use, as much of the work as they need to meet their reasonable needs, without seeking permission from the copyright owner or paying compensation.
The South African copyright law doesn't specify how much you may copy within the bounds of fair use / dealing, but it is clear that it must only be for your own use. So, multiple copies are outside of fair dealing.
There are no Copyright limitations and exceptions for blind or visually impaired persons at this stage.
