Abstract translation: 一种注射成型热塑性透镜的模内涂覆的方法，所述注射成型热塑性透镜驻留在面向水平分型线（116）的注塑机中。 首先通过将熔融热塑性树脂注入到在主夹紧力下保持闭合的边缘门控透镜形成腔中来形成光学透镜（<1 <2）。 在镜片刚性足以保持其形状时，模具（10,12）打开。 将未加压的全部计量的涂层电荷（60f）施加到透镜的中心。 通过将夹紧力从零升高到小于主夹紧力的次级夹紧力将涂层压缩成均匀厚的无条纹层，将涂层共同模制。

Abstract: A process for making a temporary photochromic patch for an ophthalmic lens. A photochromic dye is dissolved in either a siloxane base or curing agent. The base and curing- agent are combined to initiate a polymerization reaction that will result in a polydimethylsiloxane (PDMS) polymer matrix having sufficiently low molecular weight to accommodate the photochromic dye's mobility. The polymerization reaction is completed in a form to create a viscoelastic patch. The resulting patch can be trimmed and temporarily applied to an ophthalmic lens without needing adhesive.

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: A method and apparatus for coating lenses within an injection molding machine having a concave optical insert with a perimeter edge that meets the receiver ring in an annular contact region. A channel is formed throughout the annular contact region. When molding a lens with the apparatus, and according to the method, a closed-loop coating containment lip is formed by the channel. After the lens has solidified and the mold is opened, a predetermined volume of coating solution is applied and the mold is re-clamped. A uniformly thin layer of coating is cured on to the convex lens surface by avoiding coating run off and preventing mold contamination.

Abstract: A method for in-mold coating of an injection molded thermoplastic lens that resides in an injection molding machine oriented to a horizontal parting line. An optical lens is initially formed by injecting molten thermoplastic resin into an edge-gated lens-forming cavity held closed under a primary clamp force. The mold is opened at a time when the lens is rigid enough to retain its shape. An unpressurized full metered charge of coating is applied onto the center of the lens. The coating is co-molded by ramping up the clamp force from zero to a secondary clamp force less than the primary clamp force to compress the coating into a uniformly thick, fringe-free layer.
