Twain is a versatile smaller frame style designed for children ages 5 to 10 years old and teens needing smaller frames. Engineered to improve colour vision, EnChroma Twain glasses are available with our 100% UV absorbing outdoor and indoor lenses. These Italian-crafted classic frames are constructed with TR-90, a lightweight nylon-based material known for its comfort and shape retaining qualities. Case included. Available in Smooth Black or Night Sky (non-rubberized). 

About Smooth Black Frames

The EnChroma Smooth Black surface finish is a rubberized material designed to retain its shape and resist tearing and abrasion. This soft, flexible texture provides easy handling for children. 


Features
  • PROPRIETARY SPECTRAL LENS TECHNOLOGY FOR COLOR BLINDNESS: Our award-winning glasses are uniquely engineered to improve color vision and deliver a more vibrant spectrum of color.
  • “BEST-IN-CLASS” TRIVEX® LENS MATERIAL: Trivex is an optical-grade resin that delivers a superior combination of lightness, clarity, and impact protection. Trivex exceeds FDA impact resistance standards by more than 50x and is recommended by eye doctors for use in safety glasses and children’s eyewear products. Learn more about Trivex lens material.
  • LIGHTWEIGHT, DURABLE FRAME: Perfect for all-day wear, EnChroma classic style frames are made with TR-90, a lightweight, yet sturdy material often used in sportswear and known for retaining its shape. Light frames are particularly important for children given their sensitive skin on their developing nose bridge.
  • 100% UV ABSORBING: Kids generally receive three times the annual sun exposure of adults, and are at risk for developing serious vision damage later in life without regular UV-eye protection (see thevisioncouncil.org). All EnChroma lenses are 100% UV absorbing.
  • CLARITY-ENHANCING, DUAL SURFACE, ANTI-REFLECTIVE LENSES: EnChroma lenses are anti-reflective on both the concave and convex sides of the lens to maximize clarity and reduce haze. This virtually eliminates lens surface reflections to see the world the way it truly is.
  • ANTI-SCRATCH and EASY TO CLEAN: Advanced oleophobic and hydrophobic lenses repel water, dust, and sweat, making the lens easy to clean and KEEP CLEAN!
  • EXTRAS: Premium case, cleaning cloth and drawstring bag included.
  • 100% SATISFACTION GUARANTEE with every pair.
    No Risk, 60-Day Money Back Guarantee. See Return Policy.
    Comprehensive 2-year Warranty included.
    100% Quality Inspection on every pair.
  • FREE 2-DAY SHIPPING in the U.S.; World-wide shipping available.

NOTICE: EnChroma glasses are an optical assistive device for enhancement of colour discrimination in persons with colour blindness; they are not a cure for colour blindness. Results vary depending on the type and extent of colour 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 coloured contact lenses during test administration is prohibited and may invalidate the accuracy of the results.
