You said the lense system is very similar on the I/O and I/Ox, but are lenses the same? (even though the goggle part may be a bit different)
Basically what I'm wondering, if these days i don't find replacement lenses for the I/Ox online, but do find some for the I/O, can I just get an I/O lense and put it in my old I/Ox?
That is a great question! Unfortunately, the lenses are different. The I/O and I/OX have unique lens shapes and can not be swapped. If you ever have any questions, do not hesitate to reach out to our friendly, knowledgeable opticians at (877) 289-2999!
