Frequently asked questions
Find clear answers about this product, from choosing it to putting it to use.
Which mask does this spectacle insert fit?
This listing is for the C21-specific spectacle kit. It should not be substituted for the separate CM-series inserts.
Do I need the C21 version for a C21 mask?
Yes. This insert is designed for the C21. The CM-6M, CM-7M and CM-8M use a separate spectacle-kit listing.
Are prescription lenses one-size-fits-all?
No. Prescription lenses are made for the wearer. Confirm the prescription, mask model and selected lens options with our team before ordering.
