Ophthalmic optics. Contact lenses and contact lens care products. Determination of preservative uptake and release Ingestion-build-58863 Maximum sample length: 3 2001 Scope This document provides general procedures for the selection of methods, preparation of samples, and the conduct of testing for the uptake and release of preservatives from contact lenses. NOTE 1 Due to the manifest difficulties of reproducibility when coating contact lenses with mineral and organic deposits encountered during lens wear, these methods are only applicable to new and unused contact lenses. NOTE 2 Preservative depletion by a
