What this means for you
Your glasses are safe
The filter material, UV/IR blocking, and visible-light transmission are identical to the correctly-labelled batch. There is no performance difference whatsoever.
Same filter, corrected print
When your replacement arrives you can hold both pairs up. You will see the same filter — the only difference is the printed reference text now reads ISO 12312-2.
If you feel uneasy
Simply set the affected printed pair aside and use the replacement when it arrives. We completely understand and support that choice.
