If your eyesight is bad, there are things YOU can do for YOURSELF to fix that problem, without asking anyone to change what THEY are doing.
The "quiet office" is something that only some people prefer. Many of us (I'm one of them) prefer noise - music playing, background noise, etc ... I find it hard to concentrate in silence, and I know more people like me.
To ask others to be silent to ask them to change how they comfortably work to suit you. Let everyone work how they work best.
