AI Technical Summary
Technical Problem
In existing technologies, the sandwich process increases the thickness of colored contact lenses, leading to poor wearing comfort, while the coating process causes distortion of patterns and colors and complicates production control.
Method used
A colored soft hydrophilic contact lens was prepared by using an inner coating process, employing long-chain polymers to improve the flexibility of the coating material, and using highly volatile solvents for printing, combined with molding, thermosetting and turning processes.
Benefits of technology
This solved the problem of increased lens thickness, improved wearing comfort, reduced pattern and color distortion, and simplified production control.

Abstract
本发明公开了本申请公开了一种内覆膜工艺的全模压彩色软性亲水接触镜及其制备方法，其中，内覆膜工艺的全模压彩色软性亲水接触镜包括覆膜层和镜片基层，其中，使用印色机在覆膜层上印染上颜料，经加温固色阶段后形成色素层，将所述镜片基层与覆膜层和色素层经模压、热固、车削工艺后，得到所述内覆膜工艺的全模压彩色软性亲水接触镜。其主要改进覆膜材料的制作方法，添加长链的聚合物，使覆膜层更加柔软，解决弹性模量偏大的问题；同时使用挥发性较高的溶剂，油墨在印刷过程中更容易干燥，花纹颜色也不容易失真。
