摘要:
The instant invention pertains to a method and a fluid composition for producing contact lenses with improved lens quality and with increased product yield. The method of the invention involves adding a phospholipid into a fluid composition including a lens-forming material in an amount sufficient to reduce an averaged mold separation force by at least about 40% in comparison with that without the phospholipids.
摘要(中):
本发明涉及一种用于制造具有改善的镜片质量和增加的产品产量的隐形眼镜的方法和流体组合物。 本发明的方法包括将磷脂添加到包含透镜形成材料的流体组合物中,其量足以将平均的模具分离力与没有磷脂的模具分离力相比降低至少约40%。
