  • Patent number: 11248011
    Abstract: Embodiments relate to a polymerizable composition comprising a phosphorus-based mold releasing agent for an optical use whose preparation process is improved, and a process for preparing the phosphorus-based mold releasing agent. The phosphorus-based mold releasing agents can be prepared more easily and conveniently by using phosphorous pentoxide, which can easily react with a monoalcohol and/or water at room temperature in the absence of a catalyst or a solvent. In addition, byproducts are not generated during the reaction. Thus, when a lens is produced by using the mold release agent obtained therefrom, it is possible to prevent a defective appearance of the lens that may be caused by byproducts, thereby further enhancing the appearance properties thereof. Further, since separate steps for removing byproducts, specifically, such steps as washing and filtration, are not required, wastewater is not generated.

  • Patent number: 11207854
    Abstract: A method of manufacturing of an astigmatic contact lens having a toric portion and a thickness differential feature to provide lens orientation on eye portion such that said thickness differential causes the toric portion of the contact lens to properly orient in the eye of the wearer. The toric lenses are manufactured by an effective process control method for cylinder power in toric lens production by determining an amount of a mold cylinder compensation which is caused by processes in a toric lens manufacturing system including tool making, injection molding, casting and curing, wherein the mold cylinder is defined as the difference in measured radius of curvature at two orthogonal directions. A control metric is established by using the amount of a mold cylinder compensation and tolerance range and reject mold out of the control limits and improve the production yield for toric lens manufacturing.
