Update: I went into Specsavers and there wasn't many affordable options available, also didn't like the vibe in there, there were too many people working there and were all staring at me or asking if I needed help so I just left after a few mins. I've decided to just get them online then go in to collect them I know how to enter my prescription it's just the size part at the end that I don't understand how to put in, it doesn't say on my prescription but the glasses I currently have has the size on it, there are 3 numbers options to put in, do I put the first two in that order? ie of what it could be 60 [] 12 - 146 [this is what it says on my glasses, I changed the numbers for here but you get what I mean. Do I put 60 and 12 on the form in that order or 12- 146? It also says on , on my glasses it also says IE 136W. What do I put on the form?
