Revised British Standards for Terminology

The third editions of two British standards have recently been published, ISO 13666:2019, Ophthalmic optics – Spectacle lenses – Vocabulary and ISO 4007:2018, Personal protective equipment – Eye and face protection – Vocabulary. Because of some common membership of the groups revising these two documents, the wording for terms that are common to both are very similar, if not identical apart from the reference to lenses for 13666 and lenses or filters for 4007. Obviously, ISO 13666 is much more important for optometrists and dispensing opticians.

Thirty-one new terms have been added, while over 50% of terms and definitions have been revised. In some cases, this is as little as changing the order of synonyms for the term, to significant changes in the wording of definitions or notes to entry, but without change of meaning.
