ISO 18369-2:2017 specifies the tolerance limits of the principal optical and physical parameters of rigid corneal, rigid scleral and soft contact lenses at the time of manufacture. These tolerances might not apply to other purposes, for example, shelf-life studies.
Abstract
Overview
EN (Ophthalmic optics - Contact lenses - Part 2: Tolerances) is a CEN-adopted ISO standard that defines the for the principal optical and physical parameters of rigid corneal, rigid scleral and soft contact lenses. The standard specifies how dimensional, optical and some material property tolerances are to be interpreted and tested at the time of manufacture. It also clarifies that these tolerance limits might not apply for other purposes (for example, shelf‑life studies).
