3M SecureFit SF3701ASGAF-Blu OTG Safety Glasses (Over-the-Glasses, Scotchgard Anti-Fog)<\/h1>\n

The 3M SecureFit SF3701ASGAF-Blu<\/strong> are over-the-glasses (OTG) safety spectacles designed to be worn over prescription eyewear, certified to EN 166. With anti-scratch and 3M’s premium Scotchgard Anti-Fog coatings, they keep vision clear and durable for wearers who need their own glasses underneath.<\/p>\n

Product overview<\/h2>\n

The SecureFit 3700 OTG range fits comfortably over most prescription glasses, so spectacle-wearers get certified protection without separate prescription safety eyewear. Because the SF3701ASGAF-Blu carries the Scotchgard Anti-Fog and anti-scratch coatings, it resists misting and wear in busy, humid environments. The polycarbonate lens is impact-resistant to EN 166.<\/p>\n
