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

These are a few pics.

First off what you are asking about is a part number, not a serial number. Is that number under the rubber? Looks like an internal number for production. The numbers under the earsocks and not retail model numbers.

Just from the pics it looks like one of these.

I don't remember, but I suspect the parts number with "75-xxx" under the earsocks of Wires determines with earsock part to use or determine which the placement of the arm (ie. left or right arm, which model it corresponds to, etc.).

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?

They are definitely not SW 2.0. I posted up a link to the model that looks the closest to me already.

To me they look like New Square Wire with VR28 lenses. Maybe SKU 12-923? The SKU should be on the inside of the left stem unless it's been worn off.
