    Patent number: 9370906
    Abstract: Methods, devices, and systems for manufacturing ophthalmic lenses using direct injection molding are described. The present methods, devices, and systems include a mold block having a first mold insert and a second mold insert defining a lens-shaped cavity between them. A raised non-uniform region that projects into the lens-shaped cavity is incorporated in a peripheral zone of the molding surface of at least one of the mold inserts. When an ophthalmic lens is formed using the described mold block, at least one depression is produced in the lens. A gate placed at the non-uniform region allows the depression to hide any gate witness that may form when the mold is closed or separated.

  • METHODS AND SYSTEMS FOR REPLENISHING SUPPLIES IN A PRODUCT ARRAY
    Publication number: 20160042138
    Abstract: The present disclosure provides systems and methods to aid in the resupply of product arrays, such as contact lenses. In an aspect, this is accomplished by providing a physical product array to a reseller. Additionally, a computer-operated application is provided that displays a virtual representation of the physical product array. The reseller can then manipulate the virtual storage array to more easily identify the specific product slots in the array that need to be restocked, and the application can interact directly with an ordering system for the product manufacturer to submit orders for fulfillment. In an aspect, the application stores the product attributes for each slot of the product array, so that a simple visual inspection of the physical array can be translated into the proper product without a reseller having to determine product attributes for the specific array slots.
