I would not risk buying spectacles without these essential checks. However, I suppose the cheap online ones would be fine if one only needs prescription reading glasses.
The Optician didn't mark your Pupil Distance down correctly or got the pupil vertical heights wrong and that's how the error happened. The lenses had prism induced in them because they would have been a millimetre or two the wrong way. The second optician did it correctly.
Every Optician who doesn't have a lens workshop in their store has to send off and get the lenses ground to prescription and, usually, cut to fit the frame. The finished product is returned to the store to be collected by the customer. It's no different to getting lenses online, really.
I used to run an optical lab where we ground and polished the lenses to prescription and fitted them to the frames, but not many companies can do this on site. Online companies merely save money by not having to pay for store premises and sales staff. They get their lenses like most other opticians do.
