AI Technical Summary
Existing lens manufacturing processes face challenges in producing complex corrective lenses for myopia and hyperopia due to high complexity and the need to comply with surfacing, coating, and edging processes, while conventional lenses often fail to correct near vision inaccuracies.
A manufacturing method involving additive manufacturing to create a functional diffusive structure with securing elements, which is embedded in the lens element, allowing it to withstand subsequent surfacing, coating, and edging processes, and includes features like color filters and light diffusion patterns.
The method enables the production of versatile lenses with complex diffusive structures that can correct myopia and hyperopia, reduce progression, and enhance near vision accuracy, while maintaining compatibility with standard manufacturing processes.
