MCR Safety Law OG1 OTG Series Safety Glasses

The MCR Safety Law OG1 OTG is purpose-built for workers who wear prescription eyeglasses on the job. Its widened frame cavity and extended temple arms fit over most standard prescription frames while maintaining ANSI/ISEA Z87.1+ compliance — no contact lenses, no prescription safety glasses, and no safety hazard from removing PPE to read labels or see fine detail. Both available variants include UV Anti-Fog coating, since fogging is amplified in OTG designs by the trapped air volume between the prescription lenses and the safety lens. For OTG with Hi-Vis frame options or additional coating tiers, see the Klondike OG2 OTG; for a non-OTG clear anti-fog option, see the BearKat BK1.

Key Features

• Fits over most standard prescription eyeglass frames: The Law OG1's extended interior cavity accommodates typical rectangular and oval prescription frames up to approximately 140mm wide — workers verify fit with their own frames before deployment in safety-critical tasks.
• UV Anti-Fog on both variants: OTG designs trap more air volume between the prescription lens and the safety lens than standard safety glasses, which amplifies fogging. Both OG1 variants ship with UV Anti-Fog coating to address this inherent OTG fogging tendency.
• ANSI/ISEA Z87.1+ High Impact: Certified for high-velocity impact over prescription frames — the entire assembly (OTG safety glasses over prescription eyewear) meets the impact standard required by OSHA 1910.133 for industrial eye protection.
• Economy $9.99 price point: The Law OG1 is MCR's entry OTG model, providing a compliant prescription-compatible solution without the cost of prescription safety glasses, which typically range from $150–$500 with a corrective prescription.
• Clear and Gray tint options: Clear for indoor/low-light environments; Gray for outdoor or bright overhead lighting conditions.
• Polycarbonate lens with UV400: Blocks 99.9% of UVA and UVB — relevant for outdoor workers whose prescription glasses may not provide UV protection depending on their lens material and coating.

Applications

• Prescription eyeglass wearers in manufacturing: Workers on assembly lines, CNC operations, or quality inspection who cannot interrupt work to switch between prescription glasses and safety glasses — the OG1 provides compliant impact protection over existing prescription eyewear.
• Construction and trades: Electricians, plumbers, and carpenters who wear prescription glasses and move between indoor rough-in work (clear lens) and outdoor material staging (gray lens) can carry both OG1 variants economically.
• Laboratory and chemical handling: Researchers and technicians with corrective lenses who need eye protection during chemical handling — the OG1's anti-fog coating reduces the lens fogging common in lab coat environments with temperature variation.
• Visitor and contractor programs: Safety managers stocking OTG glasses for visitor use — the $9.99 price allows maintaining inventory for guests who arrive with prescription eyewear.
• Maintenance and inspection roles: Workers who perform close visual inspection tasks requiring their prescription lenses for accuracy, but who handle tools, fasteners, or equipment that creates flying debris risk.

ANSI Z87.1 Compliance

The MCR Law OG1 OTG carries ANSI/ISEA Z87.1+ High Impact certification — the standard 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 or excessive deformation.

Polycarbonate inherently provides UV protection blocking 99.9% of UVA/UVB radiation. Employers must conduct a hazard assessment under OSHA 1910.132(d) and provide ANSI Z87.1-compliant eye protection when flying particles, chemical splash, dust, or radiation hazards are present. These glasses satisfy that requirement for impact, UV, and optical distortion across all Z87.1 categories.
