MCR Safety BearKat BK3 Series Safety Glasses

The MCR Safety BearKat BK3 makes two improvements over the base BearKat BK1: a soft nose bridge that cushions the nose contact point for workers who experience pressure or soreness from rigid nose pieces during full-shift wear, and UV Anti-Fog options on both Clear and Gray tints — the only BearKat model with anti-fog on both primary lens colors. Eight variants cover Clear, Gray, Light Blue, Silver Mirror, Blue Mirror, and I/O Mirror tints. Notably, the BK3 does not include Amber (which remains a BK1 exclusive in the BearKat line) — if Amber is required, see the BearKat BK1.

Key Features

• Soft nose bridge: Cushioned nose contact area reduces pressure on the bridge of the nose during extended wear — a meaningful comfort feature for workers who experience nose bridge soreness, skin irritation, or pressure marks from rigid plastic nose pieces during full-shift use.
• Anti-fog on both Clear and Gray (BK310AF, BK312AF): The BK3 is the only BearKat model offering anti-fog treatment on both the most common tints — giving workers the fog-resistant coating on both their indoor (clear) and outdoor (gray) lens selections.
• Six tints at $9.99: Clear, Gray, Light Blue, Silver Mirror, Blue Mirror, and I/O Mirror — broad selection covering indoor, outdoor, overcast, and intense-sun conditions without the Amber variant of the BK1.
• Silver Mirror (BK317) and Blue Mirror (BK318): Same mirror options as the BK1 for intense-sun and high-glare outdoor environments — both with Duramass scratch-resistant hard coat.
• Classic BearKat wraparound frame: The BK3 uses the same full BearKat wrap geometry as the BK1, not the slimmer BK2 profile — full lateral coverage, familiar fit, broad face size compatibility.
• Duramass on non-AF variants: All non-anti-fog BK3 variants include Duramass scratch-resistant hard coat — no uncoated base-option default in this model.

Available Tints & Coatings

Applications

• Full-shift manufacturing wear: The soft nose bridge reduces the cumulative pressure and soreness that workers experience during 8–12 hour shifts — particularly relevant for workers who wear safety glasses continuously rather than intermittently.
• Outdoor construction in variable conditions: Anti-fog Gray (BK312AF) for morning outdoor work in humid conditions; Duramass Gray (BK312) for dry afternoon outdoor work — same frame, two coating choices.
• Cold storage and food processing: Clear UV Anti-Fog (BK310AF) for workers moving between refrigerated environments and ambient temperature production areas — anti-fog prevents vision impairment during thermal transitions.
• General outdoor maintenance: Silver Mirror (BK317) or Blue Mirror (BK318) for sustained outdoor work in direct sun; Light Blue (BK313) for overcast high-latitude work or workers sensitive to the darkness of standard gray tint.
• Workers with nose bridge sensitivity: Workers who previously avoided wearing safety glasses consistently because of nose bridge pressure or soreness will find the BK3 significantly more comfortable — improving compliance in PPE programs.

ANSI Z87.1 Compliance

The MCR BearKat BK3 carries ANSI/ISEA Z87.1+ High Impact certification — required for occupational eye protection under OSHA 29 CFR 1910.133 (general industry) and OSHA 29 CFR 1926.102 (construction). The Z87.1+ high-velocity rating confirms the polycarbonate lens withstands a 1/4-inch steel ball at 150 fps without fracture.

Polycarbonate inherently blocks 99.9% of UVA/UVB radiation. Employers must conduct a hazard assessment per OSHA 1910.132(d) and provide ANSI Z87.1-compliant eye protection when flying particles, chemical splash, dust, or radiation hazards exist.
