1 Scope

This document specifies the technical requirements, marking, packaging, transportation and storage requirements for photochromic lenses, and describes the corresponding test methods. This document is applicable to uncut lenses with photochromic properties and provides test methods and inspection basis for the production of photochromic lenses. This document does not apply to sunglasses.

2 Normative reference documents

The contents of the following documents constitute essential provisions of this document through normative references in the text. Among them, the dated quotations For undated referenced documents, only the version corresponding to that date applies to this document; for undated referenced documents, the latest version (including all amendments) applies to this document. GB 10810.1 Spectacle lenses Part 1.Single vision and multifocal lenses GB 10810.2 Spectacle lenses Part 2.Gradient focal length lenses GB/T 26397 Ophthalmic optical terminology GB/T 38005 Basic requirements for uncut spectacle lenses QB/T 2506 Glasses Lenses Optical Resin Lenses

3 Terms and definitions

The terms and definitions defined in GB/T 26397 and the following apply to this document. 3.1 τV0 Under specified conditions, when the lens is in a faded state, the light transmittance of the wavelength is 380nm~780nm. Note. The specified conditions are the contents of 5.3.1.4. 3.2 τV1 Under specified conditions, the lens is in a discolored state and has a light transmittance with a wavelength of 380nm~780nm. Note 1.The specified conditions are the contents of 5.3.1.4. Note 2.If the manufacturer declares the transmittance of the sample at other temperatures (5°C or 35°C) than 23°C, then keep the sample at the specified temperature of 5°C or 35°C. Under the temperature condition of 35℃, the temperature fluctuation is controlled within ±2℃. They are represented by τVw and τVs respectively, where τVw is the low temperature and τVs is the high temperature. Note 3.If the manufacturer declares medium illuminance, measure under the conditions of 15000lx±1500lx, and multiply the irradiance value in Table 3 by 0.3.Pass The intensity attenuation of the irradiation light source is achieved by placing a colorless filter at an appropriate position in the light path. 3.3 Darkening range darkenedrange ΔτD The difference between the light transmittance τV0 of the lens in the faded state and the light transmittance τV1 of the discolored state. The calculation formula is shown in formula (1). ΔτD=τV0-τV1 (1)
