Your rear view mirror turns blue due to an electrochromic auto-dimming feature. It reduces glare from headlights behind you.
To ensure the safety and comfort of drivers during night-time travel, rear view mirrors are equipped with an innovative technology commonly referred to as an auto-dimming or electrochromic mirror. This feature automatically adjusts to minimize the harsh glare from trailing vehicle headlights, which can be a significant distraction and potential hazard.
When the sensors on the mirror detect bright lights, they trigger an electrochromic reaction in the gel sandwiched between two layers of the mirror’s glass. This reaction darkens the mirror, which in turn appears blue, helping maintain the driver’s visibility and focus on the road. This technologically advanced system benefits drivers by enhancing their nighttime driving experience, promoting safety on the road, and it represents a leap forward in automotive design.
Understanding The Phenomenon
The rear view mirror turning blue is often a result of its auto-dimming feature, which is designed to reduce glare and improve visibility during nighttime driving. The auto-dimming function operates through a process where the mirror contains two layers of glass with a gel-like electrochromic material sandwiched in between. When exposed to electrical voltage, which is triggered by light sensors, the material changes opacity, creating a tinting effect that appears blue to the eye.
Additionally, temperature variations can affect the color and intensity of the blue tint. Colder temperatures can lead to a more pronounced blue hue as the electrochromic materials respond differently under various thermal conditions. Conversely, warmer temperatures might result in a lighter shade of blue or even a clear state if the dimming function is not activated.

Impact On Driving
The rear view mirror’s tendency to turn blue is a safety feature designed to enhance visibility and safety during nighttime driving. This color change happens due to a process called electrochromism, where the mirror dims to prevent the bright lights of trailing vehicles from causing a distraction. Improved visibility is crucial as it helps drivers maintain awareness of their surroundings and react to potential hazards more effectively.
Mirroring technologies also focus on light reflection control, ensuring that the driver’s vision remains unobstructed by intense light sources. With the onset of darkness, rear view mirrors employing auto-dimming capabilities alter reflectance, thus reducing the risk of temporary blindness caused by glare—a phenomenon known as the Troxler effect. Glare reduction provides a clear and comfortable view for the driver, reducing eye strain and enhancing overall road safety.
Prevention And Solutions
Rearview mirrors that turn blue are equipped with an anti-glare coating to reduce the glare from headlights behind you at night. This feature, known as auto-dimming, works through a process where the mirror darkens automatically to prevent bright light from reflecting in your eyes. To prevent the occurrence of an unusually blue tint, ensure the mirror’s surface is clean and free from dirt or residue. Regular cleaning with appropriate products is essential for maintaining the effectiveness of the anti-glare feature.
Advancements in improved mirror designs include the use of electrochromic materials which enable the transition between high reflectivity and dimmed states. These mirrors contain a gel sandwiched between two layers of glass that tints blue when an electric current is applied, triggered by sensors that detect bright light. To ensure optimal performance, it is important to avoid obstructing these sensors and to consult with a professional if the mirror does not return to its standard state in the absence of bright light.
