Retroreflective materials are designed to reflect light back to its source, making them highly visible in low-light conditions. They work by using tiny glass beads or prisms that redirect light, ensuring that it travels back in the direction it came from. This property is especially useful for safety applications, such as road signs and clothing worn by construction workers. These materials are commonly found in traffic signs, safety vests, and bicycle reflectors. By enhancing visibility, retroreflective materials help prevent accidents and improve safety for pedestrians and drivers alike, especially at night or in poor weather conditions.
