A method of determining outdoor characteristics of a photochromic optical article includes: determining environmental conditions for an area; positioning the optical article to face a first direction; determining a first incident irradiance on the optical article; determining a first surface temperature and first spectrum of the optical article; rotating the optical article to face a second direction; determining a second surface temperature and Full Characterization of Lens second spectrum of the optical article; determining a second incident irradiance on the optical article; and generating a prediction model of spectral transmission of the optical article. Further using environmental and climate conditions and to select a photochromic article most appropriate for an area.
