  • Patent number: 10649232
    Abstract: This invention relates to an ophthalmic lens with a low reflection both in the ultraviolet region and in the visible region, comprising a substrate provided on its rear main face with a multilayered antireflective coating (3-7 layers) comprising a stack of at least one layer with a high refractive index and at least one layer with a low refractive index, having a mean reflection factor on the rear face in the visible region Rm lower than or equal to 1.15%, a mean light reflection factor on the rear face in the visible region Rv lower than or equal to 1%, a mean reflection factor RUV on the rear face between 280 nm and 380 nm, weighted by the function W(?) defined in the ISO 13666:1998 standard, lower than 5%, for angles of incidence of 30° and 45°, the antireflective coating outer layer being a silica-based layer. The lens according to the invention does especially prevent the reflection of the UV radiation produced by light sources located behind the wearer.

  • Patent number: 8891072
    Abstract: An eyeglass support is adapted for pinch-holding the eyeglass (5) between three first contact portions (41-43) and three second contact portions (61-63). The first contact portions form a height reference for positioning the eyeglass whereas the second contact portions ensure application of the eyeglass against the first contact portions while conforming to any possible shape for the eyeglass. The support suits for being incorporated in a reflection measurement apparatus. In particular, it is useful for measuring reflection of eyeglasses provided with antireflecting coatings or for rating a protection against UV hazards which is provided by an eyeglass to a wearer of the eyeglass.
