ESS CDI Lenses
These are lenses only, not a pair of glasses. They mount onto a CDI frame you already own.
Please note: CDI and CDI MAX lenses are not interchangeable
The two series share almost the same name and the same lateral exchange system, but their lenses are not interchangeable:
CDI - 2.2 mm lenses.
CDI MAX - 2.4 mm lenses, wider and more curved.
Check the exact marking engraved on your frame before ordering.
Six shades available
Clear - night, indoors, overcast. Protection without loss of brightness.
Smoke - full daylight. A neutral grey that doesn't shift colors.
Yellow - low light. A contrast-enhancing lens, not a sun lens.
Copper - warm tint, increased separation in greens and browns.
Bronze - a second warm tint, offered as an alternative to copper.
Mirror Silver - mirror finish: some light is reflected on the surface before entering the lens, and the wearer's eyes are not visible from the outside.
The price varies significantly depending on the tint: mirror and polarized finishes cost considerably more than simple tints.
Lateral exchange
The lenses can be changed from the side, without tools. This is the mechanism that has defined the CDI series from the start: you adapt the tint to the light rather than changing glasses.
Material
High-strength 2.2 mm polycarbonate, specific to the CDI series.
