What Is a Blue-Tinted Rear View Mirror?
A blue-tinted rear view mirror isn’t just a stylistic choice—it’s a functional feature designed to improve your driving experience. This tint is usually applied to reduce glare from headlights at night, thereby enhancing safety on the road.
Why Do Rearview Mirrors Sometimes Appear Blue?
- Anti-Glare Coating: The most common reason is an anti-glare or “auto-dimming” feature. This coating helps prevent blinding lights from behind from disturbing your vision.
- Blue Reflection or Tint: The blue hue results from a special film or coating that filters light, which reduces eye strain and improves clarity.
- Electrochromic Technology: Modern mirrors often have a built-in electric system that automatically dims based on light intensity, giving that bluish appearance when activated.
Understanding the Functionality of Blue-Tinted Rearview Mirrors
How Does Anti-Glare Coating Work?
- Electrochromic Process: When bright headlights hit the mirror, a tiny electrical current activates a chemical layer that darkens the mirror.
- Light Reduction: This process reduces the amount of light reflected into your eyes, preventing glare during night driving.
- Self-Adjusting: Most modern mirrors automatically adjust brightness, giving off a blue hue when in dimming mode.
Types of Rear View Mirrors with Blue Tinting
| Type | Features | Price Range | Notes |
|---|---|---|---|
| Manual Dimming | Uses a lever to manually reduce glare | $50 – $150 | Simple, no power needed |
| Auto-Dimming (Electrochromic) | Dims automatically based on light | $200 – $800 | Luxury or higher-end vehicles |
| Smart Mirrors | Combines auto-dimming with additional features | $500+ | Includes features like cameras, sensors |
