I think it is important for your Mum to be there to check they are correct for her.
For me at home here in Oz, they usually measure and check the central point of vision on the lens before they are made as this can vary from person to person.
By 'multi-focals' I assume you are talking about graduated lenses or bi-focals. They can not handle tri-focals.
