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. Read More
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.
This is the 3rd pair of CX Sun SPs, and I have to say that I absolutely stand by them. My first time putting them on I was skeptical but it has changed my entire life. I never even knew that such a drastic color variety existed in the world! I would highly recommend these to anybody who is strong protan. One thing to keep in mind is FOLLOW THE DIRECTIONS! Do not flip them on and off, it will give you a splitting headache and make the initial experience much less satisfying. Also having my prescription in them is a must have, as my non script pair have become my spare shades. Why wouldn't you want to see all these new colors in crisp detail? Thank you to Enchroma for changing my life for the better.
PS:
If the CX3 Sun Sps work for you and you want to try an indoor pair, wear the shades for a few months to let your eyes adjust to the new color. at first the CX1s did nothing, but after several months of continuous wear, the indoor lenses started to have a comparable effect. I even wore them to an eye doctor when I got my script updated and out of curiosity the doctor gave me a colorblind test, and I scored better with the CX1s than without. Not a drastic difference by any means, but proof enough that they work for strong protan color blindness.
