Meet Altavista, a replacement for a successful but retiring Receptor fitover frame. 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. To wear over prescription glasses, the total width of the glasses should be 128 mm or less, and the height of the glasses 44 mm or less. To reduce internal reflections between the lenses, glasses that have an anti-reflection coating are recommended. EnChroma® Altavista. Outdoor colorblindness glasses for adults.
