摘要： The present disclosure includes optical articles comprising a lens having first and second lens surfaces and a protective layer having first and second protective surfaces that is coupled to the lens such that the first protective surface is disposed on the second lens surface. The optical article can comprise a plurality of convex or concave optical elements defined on the second lens surface or the first protective surface. The protective layer can have a maximum thickness larger than a maximum height of each of the optical elements such that the protective layer encapsulates the optical elements.

摘要： Optical polymeric sheets with specific ranges of optical retardation, elastic modulus, and Shore A hardness were used to construct flexible polar patches. The polar patches conform to non-polarizing lenses of various diopter bases and provide polarizing efficiency that is comparable to regular polarizing lenses.

摘要： Disclosed are methods for preparing partially polarized optical articles. A polarizing element is used to cover at least a portion of the front surface of an optical article to form a polarizing zone and a non-polarizing zone on the optical article. The optical article is then tinted to produce a gradual color transition between the polarizing zone and non-polarizing zone of the optical article.

摘要： A method for injection molding of a weld line free minus power lens element comprises injecting a melt of thermoplastic material at a temperature higher than a glass transition temperature (Tg) of the thermoplastic material in an initial molding cavity delimited by two facing mold inserts, wherein the melt of thermoplastic material comprises at least one UV absorber. During the injecting, the two facing mold inserts are moved toward one another to define a final molding cavity whose volume is less than that of the initial molding cavity. After cooling and disassembling of the two facing mold inserts, the weld line free minus power lens element is recovered. One of the two facing mold inserts comprises a flat surface facing the initial molding cavity, thereby to form a flat surface on one side of the weld line free minus power lens element. The other of the two facing mold inserts comprises a convex surface facing the initial molding cavity, thereby to form a concave surface on an opposite side of the weld line free minus power lens element.

摘要： A method for injection molding of a plus power lens element comprises injecting a melt of thermoplastic material comprising at least one UV absorber at a temperature higher than a glass transition temperature (Tg) of the thermoplastic material in an initial molding cavity delimited by two facing mold inserts. During the injecting, the two facing mold inserts are moved toward one another to define a final molding cavity whose volume is less than that of the initial molding cavity. After cooling and opening of the mold cavity, the plus power lens element is recovered. One of the two facing mold inserts comprises a flat surface facing the initial molding cavity, thereby to form a flat surface on one side of the plus power lens element, and the other of the two facing mold inserts comprises a concave surface facing the initial molding cavity, thereby to form a convex surface on an opposite side of the plus power lens element.

摘要： Disclosed are systems and processes for generating a finished or semi-finished lens, such as a spectacle lens, from a lens blank that includes an intermediate functional layer. Some embodiments of the process involve locating the functional layer and positioning the lens blank according to the location of the functional layer. The location of the functional layer can be ascertained by measuring the thickness of one or more layers of the lens blank. The lens blank can be surfaced on one or both sides to form a finished or semi-finished lens. Other embodiments are also described.
