Front surface mirrors are more expensive to manufacture than second surface mirrors, but they offer a number of advantages, including:

• Superior image quality: Front surface mirrors produce a sharper, more accurate reflection than second surface mirrors. This is because there is no secondary reflection from the back surface of the substrate to interfere with the image.
• Increased durability: Front surface mirrors are more durable than second surface mirrors because the reflective coating is protected by the substrate. This makes them less susceptible to scratching and damage.
• Reduced glare: Front surface mirrors produce less glare than second surface mirrors. This is because the reflective coating is applied directly to the substrate, which eliminates the air gap between the coating and the substrate.
