In this article product developments for ophthalmic lenses are discussed: new materials, designs and coatings. High-index plastic substrates allow to offer corrections which are simultaneously light and thin and for the first time there are high performant plastic photochromic lenses. Head and eye movements with latest generation's progressives are very similar to natural vision behaviour. Special aspheric designs have been developed for comfortable vision for near and intermediate distances. Finally there are new coatings which protect the high quality surfaces of plastic lenses distinctly longer than before.
新材料、设计和涂层。高折射率塑料镜片能够提供轻薄的矫正镜片，并且首次出现了高性能的塑料光致变色镜片。最新一代渐进多焦点镜片的头部和眼睛运动与自然视觉行为非常相似。已经开发出特殊的非球面设计，以实现近、中距离的舒适视觉。最后，有了新的涂层，能比以往更有效地保护塑料镜片的高质量表面。
