Abstract: Described herein is a method for producing photochromic silicone hydrogel contact lenses in a relatively efficient and consistent manner from a polymerizable composition under a controlled thermal curing scheme. The main polymerizable components in the polymerizable composition are a high radical-reactive hydrophilic (meth)acrylamido monomer, a high radical-reactive siloxane-containing (meth)acrylamido monomer, and a polysiloxane vinylic crosslinker(s) free of low-reactive ethylenically unsaturated group as the main crosslinker. The thermal free radical initiator having a 10 hour half-life temperature (T10hλ) of from about 50° C. to about 90° C. The controlled thermal curing scheme includes maintaining a first curing temperature of from about (T10hλ−20)° C. to about T10hλ° C. for a first curing time and maintaining a second curing temperature of from about (T10hλ+10)° C. to about (T10hλ+35)° C. for a second curing time.

Abstract: Described herein is a method for producing photochromic contact lenses, in particular, photochromic silicone hydrogel contact lenses. The method comprises a step of cast molding of a lens-forming composition including an iniferter to form an unprocessed contact lens having iniferter moieties covalently incorporated into its polymer matrix and a step of iniferter-induced graft-polymerization of a photochromic vinylic monomer to the polymer matrix only in its central region which is circular and concentric with the central axis of the unprocessed contact lens. The obtained photochromic contact lens has a central pupillary region that only can undergo a reversible color change upon exposure to UV/HEVL-radiation.

Abstract: An electrochromic element suppresses reflection at an interface between an electrode layer and a substrate and does not impair a wearing feeling and the like, and a spectacle lens using the electrochromic element. An electrochromic element includes a substrate and an electrochromic film disposed to be superimposed on the substrate, the electrochromic film includes an electrode layer and an electrochromic layer, and a luminous reflectance of an interface between the electrode layer and the substrate side is 1.0% or less. It is preferable that the electrode layer be a transparent electrode layer made of ITO, and a luminous reflectance of an interface between ITO and the substrate side be 1.0% or less.
