We are going to make an appointment to get our geometry checked. Last time we we had this done, we were shown a computer screen and told it needed this, that and the other done and we stood there like a couple of numpties and ok'd whatever they suggested as we hadn't got a clue.
This time, we would like to understand more about the information produced by the equipment, what it means, what questions to ask and so forth. Can anyone help with this please?
