We continue to make advancements in reflective material innovations and play a longstanding role in on-the-job safety. Our products are proven to be bright, durable and high quality, with worldwide technical, marketing and lab support.
Retroreflectivity helps the eye perceive objects in low-light conditions when illuminated by a light source. In more scientific terms, retroreflection occurs when light rays are returned in the direction from which they came. Retroreflective materials appear brightest to an observer located near the original light source. Since very little light is scattered when the light is returned, retroreflective materials enhance the contrast of the wearer for an observer located near the original light source.
