ALSEYE EnChroma Altavista Deutan Color Blind Glasses 2 in 1 Accessories

EnChroma Altavista Deutan Glasses

These EnChroma Altavista glasses are designed for outdoor use by people with Deutan colour blindness. The wrap-around frame fits comfortably over most prescription eyewear and blocks stray light from the top and sides. They are supplied new as a 2-in-1 accessory for computer users who need enhanced colour vision outdoors.

Outdoor Deutan lens for red-green correction

The Outdoor Deutan lens boosts greens and normalises the red-green ratio so that hundreds of hues become visible and distinguishable. Patented lens technology developed over more than a decade enhances colour distinction, improves contrast and renders whites and neutral tones naturally. The optics filter out 100% of harmful UVA and UVB light while providing impact protection.

Suits Deutan users with smaller prescription frames

Buyers with Deutan colour blindness who wear prescription frames up to 135 mm wide and 42 mm high can wear these over their existing glasses. People with Protan colour blindness cannot use this Deutan lens and should look for a Protan-specific model instead. Anyone whose prescription frames exceed the stated width or height limits will not achieve a comfortable fit.
