Altavista Fitover | Lx1 Light Amber

New Altavista improves on the ability to be worn over your prescription glasses by increasing its size where it was needed most, along the horizontal. The wrap-around design provides the right kind of protection and coverage from stray light along the top or side of the frame. This rectangular lens shape and superior coverage ensures that EnChroma lenses deliver exactly the filtering intended without top or side glare for those most bothered by excess light. That means that those with sensitive eyes or problems with glare, contrast and color vibrancy should use this frame for its excellent protection.

Case included. Frame size: Large 64-12-128.

Fitting Guide
Low vision glasses Altavista fitting size

To wear over prescription glasses, the total width of the glasses should be 135 mm or less (5 3/8ths inches), and the height of the glasses 42 mm or less (1 5/8th inches). To reduce internal reflections between the lenses, glasses that have an anti-reflection coating are recommended.

How does this warning relate to EnChroma glasses?

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.
