I/OX lens are the same as I/O?
They are interchangeable? I/O lens can be used in I/OX frames?
I did try ebay and I discarded them because I thought they are not interchangeable.
Ok, thanks for the info.
No, my bad - I missed the X in your original post. Pretty sure I have seen the IOX lenses on eBay as well, but right now it is only the complete Googles.
Keep an eBay search and also drop an email to Smith customer service.
