The Skullerz MODI Over-the-Glasses (OTG) Anti-Scratch and Enhanced Anti-Fog Safety Goggles feature an oversized, wrap-around lens for a wide field of vision and seamless fit over prescription frames. The lens features Fog-Off+ technology for durable scratch-resistance and enhanced permanent anti-fog performance that won't wash or rub off for clear viewing no matter the job—particularly useful for those working with dust masks or around extreme changes in temperature. The soft gasket lining forms to the wearer's face for a comfortable, customized fit while sealing out dust, debris and particles. The vented frame allows for airflow and improved anti-fog performance. The soft, woven elastic strap is adjustable and comfortably secures on heads, hard hats or caps.
