I have been told that they are Square Wire 2.0 spring hinge but I still don’t know the sku number to confirm the lenses I need to order are the correct ones. Does anyone know where I can find this number?

These are a few pics.

Hi all

I have a pair of Square Wire (spring hinged) glasses which have the serial number 75-789NC and I am trying to get a set of replacement lenses for them but I cannot find them by searching for that number. I have found various glasses that look similar but as there seem to be a number of variations/versions I don't want to order up the wrong lenses. Any one able to help or point me in the right direction.
Thanks

Bought my first pair of Oakley sunglasses about 14 years ago on a trip to USA. Been back a few times and have picked up another couple of pairs. Not the biggest collector of Oakley's but I do like them and probably won't buy any other make now.
