MCR designs OTG glasses with anti-fog standard because the enclosed air space between prescription lenses and the safety lens creates significantly more fogging than standard safety glasses.

OSHA 29 CFR 1910.133(b)(2) and 1926.102 permit the use of safety glasses worn over prescription frames as a compliant method of providing eye protection, provided the safety eyewear carries ANSI Z87.1 certification. The Law OG1 OTG is ANSI\/ISEA Z87.1+ certified and satisfies this requirement.
