1.61 Photogrey (Spin Coating) Photochromic Finished Lens

● Spin coating is a thin film preparation technology that can realize uniform coating of materials on the substrate surface by high-speed rotation.

● The spin coating technique places the color-change film on the surface of the lens, so the color only changes on the surface of the lens.

● The color changes faster, the color is deeper, and the fading is more uniform.

● Owing to its rapid and uniform photochromic properties, spin coating helps the lens better adapt to changes in ambient light, reducing visual discrepancies and providing a more comfortable and natural visual experience.
