If you are at risk for an eye injury at work, you should wear appropriate protection. Safety glasses should be individually assigned and fitted. Eye size, bridge size, and temple length all vary. Wear safety glasses so that the temples fit comfortably over the ears. The frame should be as close to the face as possible and adequately supported by the bridge of the nose. NeoVision’s opticians will ensure that your safety glasses fit properly.
Clean your safety glasses daily. Keep your glasses in a case when not in use. Always store your safety glasses in a clean, dry place so that they cannot fall or be stepped on. Avoid rough handling that can scratch lenses. Scratches not only impair vision but can also weaken lenses. Replace scratched, pitted, broken, bent or improperly-fitting glasses. Damaged glasses interfere with vision and do not provide protection. Replace damaged parts only with identical parts from the original manufacturer to ensure the same safety rating.
Lenses: Certified safety glasses have polycarbonate lenses. They are stronger than the regular CR-39 lenses, are impact-resistant, and come in prescription and non-prescription (plano) forms. These lenses are the most impact resistant lenses available and are the lenses of choice in young people, sports glasses, and safety glasses for eye protection. Polycarbonate lenses are sometimes referred to as featherweight lenses. They also absorb all harmful UV light.
Markings on safety glasses: The manufacturer or supplier logo is marked (or etched) on all approved safety lenses, frames (front and temple), removable side shields, and other parts of the glasses or goggles.
Frames: Safety frames are stronger than everyday frames and are often heat resistant. They are also designed to prevent lenses from being pushed into the eyes.
