Like most eyewear frames, EnChroma frames may contain stainless steel hardware components such as wire, hinges and screws. Stainless steel is an alloy of iron, chromium and nickel. Metallic nickel has been classified as a possible carcinogen and is on the Prop 65 warning list.
What testing does EnChroma perform on its frames?EnChroma uses an independent third party laboratory to test its frames and lenses for compliance with international standards including EN 16128:2015. EnChroma frames are compliant with the requirement for upper limit of nickel migration as specified in paragraph 1(b) and (c) of entry 27 of Annex XVII to the REACH. REACH is a European Union regulation concerning the Registration, Evaluation, Authorisation and restriction of Chemicals. However, the REACH is not recognized by the State of California.
