I'm having a bit of an argument with Boots at the moment: I went and got an eye test there a few months ago. Recently, I went and got some new glasses, based on the prescription that came out of said eye test.
Whilst at home one day, I noticed my new glasses weren't as sharp as my old ones. In order to be sure, I went back to the opticians where I got the glasses from to check they were accurate to the prescription: They were.
I then went back to Boots and told them what the situation was: The rather conceited manager explained all the ins and outs and ended up by saying "this is the prescription YOU and the optician came up with". Now, I know I have a role in the eye test, but it seems a bit haphazard to rely on someone's subjective view. Is there not a more precise way of doing it?
