CONVEX MIRROR

A road safety convex mirror (also known as a diverging or traffic mirror) is a curved outdoor mirror that bulges outward to provide a wide, 130-degree fish-eye view. By expanding the field of vision, these mirrors eliminate dangerous blind spots at sharp curves, intersections, driveways, and parking areas to prevent vehicle and pedestrian collisions.

Key Specifications & Materials

• Lens Material: Modern outdoor traffic mirrors primarily use unbreakable polycarbonate (PC). Polycarbonate is highly shatter-resistant, lightweight, and coated with a protective film to stay scratch-resistant and weatherproof. High-end public roads may sometimes use premium polished stainless steel.
• Backing & Frame: Typically structured with a heavy-duty ABS plastic back or fiberglass shell, usually finished in a high-visibility orange or red casing.
• Built-in Sun Shade: Most outdoor units feature an overhanging top visor/hood to block glare from the sun and shield the lens from rain.

Mirror Size vs. Viewing Distance

Choosing the correct mirror diameter is critical. The general rule is that the total viewing distance equals the distance from the target object to the mirror, plus the distance from the mirror to the driver.
