All of our safety glasses comply with standards set by ANSI (American National Standard Institute). Safety glasses fulfilling this standard will bear the marking Z87, Z87+ or Z87-2.

Z87- Basic Impact indication

To determine the basic impact properties of a material, a steel ball is dropped from a relatively high position onto the object. Safety lenses must not break, crack or chip to pass the test and Safety frames must be able to hold the safety lenses in place without any detachment or displacement of the lenses. Lenses must not be thinner than 2mm thick in diameter.

Z87+ - High Impact indication / Ballistic

To qualify, Lenses and Frames are tested together as a whole. During the test, steel projectiles will be shot at them at a speed of about 45m per second, directed at different angles and positions. Safety lenses must not break, crack or chip to pass the test and Safety frames must be able to hold the safety lenses in place without any detachment or displacement of the lenses. Lenses must not be thinner than 3mm thick in diameter.

Z87-2 - Prescription Safety Frames.

Side shields are available to provide a bigger coverage of protection. Side Shields will have to pass the high velocity impact test and will also bear the marking Z87.

Frames and lenses that do not fulfill these requirements should never be used as safety glasses. Are your precious eyes protected from the many potential dangers present at your workplace?

Thank you very much. Have a great evening.
