In an era where eyewear is as much a fashion statement as it is a functional necessity, photochromic lenses have undergone a remarkable transformation. At the forefront of this innovation is spin-coating technology—a advanced manufacturing process that applies photochromic dyes onto lens surfaces through high-speed rotation. This method ensures unparalleled uniformity, exceptional durability, and consistently high performance.
Unlike traditional methods such as In-mass or dip-coating, spin-coating allows for precise control of the photochromic layer’s thickness and distribution. The result is a lens that offers faster response to UV light, more complete fading indoors, richer options of different indexes, and longer service life. These advantages make spin-coated photochromic lenses increasingly popular among users who seek both aesthetic appeal and optical excellence.
Building on this cutting-edge technology, UNIVERSE OPTICAL is proud to introduce the U8+ Full Series Spincoat Photochromic Lenses—a product line designed to exceed market expectations and cater to diverse consumer needs.
Exceptional Performance Redefined
The U8+ series delivers outstanding visual performance through several key improvements:
- Ultra-Fast Transition: The lenses darken rapidly upon UV exposure and revert to a remarkably clear state indoors, with up to 95% light transmittance, ensuring seamless adaptation in varying light conditions.
- Enhanced Darkness under Sunlight: Thanks to optimized dye performance and spin-coating precision, the U8+ lenses achieve deeper and more beautiful pure colors in bright sunlight compared to conventional photochromic lenses.
- Excellent Thermal Stability: Even in high-temperature environments, the lenses maintain stable darkening performance.
- True Color Representation: With over 96% color similarity to leading international brands, the U8+ series offers classic pure grey and brown colors, along with fashionable tints including Sapphire Blue, Emerald Green, Amethyst Purple, and Ruby Red.
Comprehensive Product Range
Understanding that every wearer has unique needs, UNIVERSE OPTICAL offers the U8+ series in a complete range of options:
