I found it took me months to get used to them but sore eyes is an odd one. Eye strain and sort of headachy and tired yes but not really sore as in you have hay fever or something.
The reason it took me so long and actually I am still not really comfortable is because I wear contacts as well so swap backwards and forwards. So the glasses dont really become part of me
I still tend to take mine off to talk to people ! I know its daft but I become aware of my glasses and then cant concentrate.
I would have another word with the optician.
