Handcrafted Mazzucchelli Zyl Acetate - These frames are handcrafted from Mazzucchelli Zyl acetate. This is high quality Italian material made of renewable wood pulp and natural cotton fibers.
CR-39 - CR-39 has been the tried and true method for eyeglass lenses for years. Why? They're lightweight, far less prone to shattering than glass and scratch resistant.
100% UVA/UVB Protection - These lenses come with 100% protection from the harsh rays of the sun.
Optics by Carl Zeiss Vision - Carl Zeiss Vision are the premiere lens manufacturers in the world, and you get to enjoy their renowned quality lenses in these shades.
AR5+ - The application of a "5 Layer Anti-Reflective" coating on the inside of a lens eliminates the blur, distortion, and reflection of light waves entering from the back of the lens. In conjunction with their standard polarization, internal and external reflections are then eradicated, leaving the clearest image possible. The plus refers to an added hard exterior coat, which makes these lenses extremely scratch resistant. It also means easy cleaning because these lenses repel skin oils, dust and other liquids thanks to a Ripel Oleophobic coat.
Polarized Lenses - Polarized lenses eliminate scattered, reflected light and drastically reduce glare to increase vision quality in bright conditions.
These measurements include the height of the lens, the width of the bridge, the width of the lens and the length of the arms measured in millimeters.
For example, a 56-17-45-144 frame:
1) Lens Height - 56mm
2) Bridge Width - 17mm
3) Lens Width - 45mm
4) Arm Length - 144mm
