- spectacle frames and frames fitted with lenses whether or not the lenses are optically worked: sunglasses, protective glasses and corrective glasses.
- optical instruments such as binoculars, monoculars, other optical telescopes and their mountings; optical astronomical instruments.
- compound optical microscopes including those for photomicrography and micro-projection.
- other optical appliances and instruments (e.g. telescopic sights for fitting to arms, machines or appliances; lasers other than laser diodes; hand magnifying glasses and magnifiers; mounted, optically worked, glass mirrors, door eyes).
- still or cinematographic cameras; cameras of all types for all purposes including those used to prepare printing plates, for underwater or aerial photography, or for producing microfilm or microfiche; cinematographic sound cameras.
- image projectors, enlargers and reducers including microfilm, microfiche or other microfilm readers.
