Quick answer
Danyang District in China has integrated lithography equipment into eyeglass lens production, enabling the creation of ultra-thin nanostructured lenses measuring just 2 mm in thickness, even for high diopters up to 1500.
Danyang District in China, recognized as the global leader in eyeglass lens production, has integrated lithography equipment into its manufacturing processes. This technology, previously used primarily in the semiconductor industry, enables the creation of nanostructured lenses with exceptional precision.
With this new approach, lens thickness has been significantly reduced to just 2 mm, even for prescriptions as high as 1500 diopters. This breakthrough offers new possibilities for the optical industry, as these lenses combine lightweight durability with high image quality.
Danyang accounts for nearly half of the world's eyeglass lens production, and the adoption of lithography could further strengthen its market position. The technology also optimizes production processes, reducing costs and enhancing product competitiveness.
