Abstract: A method and coating used to prepare a photo chromically-enabled bifocal.ophthalmic lens. The method and equipment includes injection molding a single vision lens (10e), for example, from polycarbonate. The clamp opens vertically and the top insert (20) is exchanged for a bifocal mold (30) having a base curve similar to the single vision lens. The thermos et coating includes compounds from several acrylate classes, and is applied to the single vision lens. The coating may include a photochromic dye. The coating is also formulated to receive a photochromic solution through an imbibition process.
Abstract translation: 用于制备光致变色双焦点透镜的方法和涂层。 该方法和设备包括例如从聚碳酸酯注塑成型单视觉透镜（10e）。 夹具垂直打开，并且顶部插入件（20）被更换为具有类似于单视觉透镜的基本曲线的双焦模具（30）。 热水涂层包括来自几种丙烯酸酯类的化合物，并且被应用于单视透镜。 涂层可以包括光致变色染料。 涂层也被配制成通过吸收过程接收光致变色溶液。

Abstract: A composition adapted for use in an in-situ coating process for coating an optical surface for ophthalmic applications. A coating composition according to the present invention includes at least one multifunctional acrylate compound which is cured onto a heated surface with controlled coating distribution in an ophthalmic injection mold. For example, the composition may include an acrylic base cured with an initiator, e.g., t-butyl perbenzoate, and may further include at least one catalyst and at least one metal salt. An acrylic base according to the present invention may include a combination of monofunctional and/or multifunctional acrylate and/or methacrylate compounds.
