Which code does this activity belong in?
NAICS 333314 covers the manufacture of optical instruments and lenses used for viewing and magnification, including binoculars, microscopes, telescopes, and prisms, as well as lens coating, polishing, and mounting activities. The boundary distinguishes this code from photographic and photocopying equipment manufacturing, which covers cameras, projectors, and film developing machinery; optical instruments are distinct optical viewing devices rather than equipment designed to capture or reproduce images. Ophthalmic lenses and related eyewear manufacturing fall outside this scope.
