EnChroma Altavista is our fitover wrap-around frame that delivers superior coverage and clear, vibrant color for those with most types of color blindness. Altavista fitover glasses are designed to be conveniently worn over prescription glasses. Wrap-around construction enables excellent coverage from stray light through the top and side of the frame. Ideal for those with sensitive eyes or medical concerns. To wear over prescription glasses, the total width of the prescription 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.
Case included. Frame size: Large 64-12-128.

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.
