How to use

Allow the lenses time to adapt when moving between shaded and sunny areas; adaptation speed depends on ambient temperature and light intensity. Store the eyewear in a protective case when not in use and clean the lenses with a soft microfiber cloth and appropriate lens cleaner to preserve coating and clarity.
