Anti-reflective coatings are thin layers applied to lenses, screens, and other surfaces to reduce glare and reflections. These coatings work by minimizing the amount of light that bounces off the surface, allowing more light to pass through. This enhances visibility and improves the clarity of images, making them particularly useful for glasses, camera lenses, and electronic displays. The technology behind anti-reflective coatings involves multiple layers of materials, each designed to interfere with specific wavelengths of light. By carefully controlling the thickness and composition of these layers, manufacturers can create coatings that effectively reduce reflections while maintaining durability and scratch resistance.
