Glass microspheres are added in order to improve the identification of lines at night, to improve the brightness and durability of the marking. Glass beads, usually 0.1-1.4 mm in diameter, are colourless and transparent; they reflect light from vehicle's headlights back toward the driver and foremost protect the road marking from abrasion.
They are also used as a material to increase the scanning range of barcodes in factory settings. The sheeting consists of retroreflective glass beads, microprisms, or encapsulated lenses sealed onto a fabric or plastic substrate. Many different colors and degrees of reflection intensity are provided by numerous manufacturers for various ...
Glass beads composed of soda lime glass are essential for providing retroreflectivity in many kinds of road surface markings. [1] Retroreflectivity occurs when incident light from vehicles is refracted within glass beads that are imbedded in road surface markings and then reflected back into the driver's field of view.

Commercial retroreflective beads thus vary in index from around 1.5 (common forms of glass) up to around 1.9 (commonly barium titanate glass). The spherical aberration problem with the spherical cat's eye can be solved in various ways, one being a spherically symmetrical index gradient within the sphere, such as in the Luneburg lens design.
Raised reflective markers, such as plastic, ceramic, or metal ones, include a lens or sheeting that enhances their visibility by retroreflecting automotive headlights, while glass road studs gather automotive headlights with a dome shape and reflect the lights with a reflective layer within.
Cat's eye glass body and principle of operation; back (left) face is mirror-coated. The cat's eye design originated in the UK in 1934 and is today used all over the world. [1] The original form consisted of two pairs of retroreflectors set into a white rubber dome, mounted in a cast iron housing. This is the kind that marks the centre of the ...
