The safety spectacles are made to work in dynamic and dusty environments. A soft eye seal with a large contact surface surrounds the eyes and hinders particles to enter. Thanks to indirect ventilation holes and a special coating on the inside of the lens, fogging is nearly impossible. By users choice the temples can be replaced by a headband allowing the SP1000™ to be worn together with hearing muffs without loss of attenuation and allowing the wearer to have a tight secure fit with high protection from liquid splashes. A hardcoat on the outside of the lenses ensures permanent and unobstructed vision even while working hard.
