ESS 5B Mirrored Gray
The mirror works before the tint. It reflects part of the incident light on the surface of the lens before it penetrates it – the filtering is therefore done in two steps instead of one.
What it changes
On a simply tinted lens, all light reduction relies on the mass of the glass. With a mirror finish, part is reflected immediately and only the rest is absorbed.
A often sought-after side effect: from the outside, the eyes are not visible.
Mirrored Gray vs. Smoke Gray
The 5B Smoke Gray offers the same tint family without the mirrored finish, at a slightly lower price. If the discretion of the eyes is not important to you, there is no other justification for the difference.
Construction
Frame injected in high-resistance polymer, with wider temples that close the peripheral protection instead of leaving a gap on the sides.
The temple tips are low profile: fewer contact points under a cap, hat, or helmet.
Unbreakable polycarbonate lenses extruded, cut, then thermoformed, covered with a hard anti-scratch and anti-reflective coating.
The 5B Range
Smoke Gray - Hi Vis Orange or Tan frames.
Hi-Def Bronze - Olive or Camo frames.
Mirrored Gray - Black frame.
Copper - Black frame.
Polarized Mirror Green - Grey frame.
The price depends on the tint and the frame: two frames with the same lens may not be the same price.
5B or Credence
Both ranges share the construction, coating, and standards. The difference is morphological: the manufacturer explicitly destines the Credence for faces above average. If a standard frame compresses your temples, the Credence is what you should look at.
Standards declared by the manufacturer
Lenses classified as ballistic according to MIL-PRF-32432 and ANSI Z87.1-2015, with 100% UVA and UVB filtration and distortion-free optical clarity.
