  • Publication number: 20150227877
    Abstract: Systems and methods for processing jobs in a Laboratory Management System (LMS) are disclosed. In some embodiments, a method may include identifying, by a user operating an LMS interface provided via one or more computer systems, an electronic record related to one of a plurality of manufacturing orders, determining, by the user, that the identified manufacturing order is being temporarily suspended from production, and adding the electronic record to a hot jobs queue in the LMS interface.

  • Publication number: 20140247423
    Abstract: An optical system having a transmission pattern comprising at least a first zone Z1 extending from at or about 380 nm to a first limit L1 between Z1, and a second zone Z2. A third zone Z3 extends from a second limit L2 between Z2 and Z3 to about 780 nm. L1 may be greater than or equal to or about 436 nm. Second limit L2 may be greater than L1 and smaller than or equal to or about 487 nm. The average transmission values T1, T2, T3, in each zone Z1, Z2, Z3 may be: T2>5*(T1+T3)/2, with T1 the average transmission over Z1, T2 the average transmission over Z2, T3 the average transmission over Z3. T1 and T3 may be greater than or equal to or about 3% and smaller than or equal to or about 70%. T2 may be greater than or equal to or about 75%.

  • Publication number: 20140247424
    Abstract: Methods for optimizing postural prism to be added to a pair of ophthalmic multifocal lenses (lenses) adapted to a wearer and to slow down myopia progression are described. The method includes an initial pair of lenses in a providing step S1. In a postural prism adding step S2, a same postural prism is added to each lens. In a gazing step S3, the wearer gazes at a first distance target through the lenses with the added postural prism. A gazing direction determining step S4 determines the wearer's gazing direction during S3. Steps S2 to S4 may be repeated while changing the added postural prism, wherein the added postural prism is smaller than or equal to a maximum prism value. Steps S2 to S4 may be repeated to determine the smallest added postural prism for which the wearer's gazing direction in step S4 passes through the first vision zone.

  • Patent number: 4062627
    Abstract: An improved flexible contact lens is provided having hydrophilic and lipophobic properties which allow extended duration of wear by eliminating or greatly reducing the risk of rupture of the natural tear film produced by the cornea. These properties are achieved by crosslinking a selected water soluble polymer which has been grafted onto a pre-formed substrate, for example crosslinking polyvinyl pyrrolidone which has been previously grafted onto a silicone substrate. The grafting and the crosslinking are accomplished in separate stages.
