Most MCR economy safety glasses use translucent, brightly colored, or two-tone frames that look overtly casual or industrial. The BlackKat BL's solid black frame is appropriate for client-facing work environments, professional trades, and any situation where the worker's appearance reflects on the employer. If tint selection or frame coverage is the priority, the BearKat BK1 or Swagger SR1 offer more options at the same price.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border-bottom:1px solid #2a2a2a;margin-bottom:2px\"\u003e\u003csummary style=\"cursor:pointer;padding:12px 0;color:#e0e0e0;font-weight:600;list-style:none\"\u003eDoes the BlackKat BL come in anti-fog?\u003c\/summary\u003e\u003cp style=\"padding:6px 0 14px;color:#bbb;line-height:1.7;margin:0\"\u003eYes — the BL110AF (Clear lens with UV Anti-Fog coating) is the anti-fog option in this series. The UV Anti-Fog treatment is MCR's basic anti-fog tier, suitable for moderate fogging conditions.

It is not photochromic (does not chemically darken) — the shift in perceived tint is based on the reflective properties of the mirror coating interacting with ambient light levels.

The all-black pigmentation does absorb slightly more UV and heat in direct sunlight, but at the exposure levels and durations typical of safety glasses use, this has no measurable impact on frame life.
