EnChroma® Derby Cx3 Sun is an iconic browline frame prescription glasses with lens technology engineered to deliver clear, bright color and 100% UV protection for those with mild, moderate and strong Deutan color blindness. Features a combination of cellulose acetate and stainless steel materials with adjustable nose pads. The sophisticated silhouette offers trend-forward stylings for all face shapes. Durability qualities inherent in the premium acetate and stainless steel spring hinges provide a more flexible fit that contours to the face over time.
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.

NOTICE: EnChroma glasses are an optical assistive device for enhancement of color discrimination in persons with color blindness; they are not a cure for color blindness. Results vary depending on the type and extent of color vision deficiency per individual. EnChroma does not endorse the use of the glasses to pass occupational screening tests such as the Ishihara test: these tests may be required in occupations where public safety is at risk such as public transport operators, electricians and first responders. Wearing of any filtering lens including colored contact lenses during test administration is prohibited and may invalidate the accuracy of the results.
