  • Publication number: 20230004023
    Abstract: The invention provides a delamination-resistant embedded silicone hydrogel contact lens having an insert that is embedded in a silicone hydrogel bulk material. The insert is made of a crosslinked polymeric material having a refractive index higher than that of the silicone hydrogel bulk material by at least 0.07 and comprises a diffractive structure disposed on one of the front and back curve surfaces of the insert for providing a diffractive power that contributes to the overall optical power of the contact lens.

  • Publication number: 20220326412
    Abstract: The invention is directed to an embedded hydrogel contact lens, which comprises an insert sandwiched between two layers of hydrogel materials and can be produced according to a cast molding method including the procedures involving two females halves (FC1 and FC2) and two male halves (BC1 and BC2) and three consequential molding steps involving three molding assemblies: the 1st one formed between FC1 and BC1 for molding an insert; the 2nd one formed between FC1 and BC2 for molding a lens precursor having the molded insert embedded in a layer of a hydrogel material in a way that the front surface of the molded insert merges with the convex surface of the lens precursor; and the 3rd one formed between FC2 and BC2 for molding an embedded hydrogel contact of the invention.

  • Publication number: 20210191154
    Abstract: A hybrid diffractive and refractive contact lens, and methods of treatment of optical conditions using such a lens. A first lens portion is formed from a first lens material having a first index of refraction and includes at least one diffractive optical element. A second lens portion is formed from a second lens material having a second index of refraction different from the first index of refraction. The diffractive optical element may be embedded within the second lens portion to provide comfort, tear film stability, and optical performance.

  • Patent number: 9421831
    Abstract: A magnetic force transmission type tire pressure sensor device and related setting tool and setting method is disclosed. The invention uses a magnetic force sensor unit in the tire pressure sensor device to receive lines of magnetic flux being transmitted by a magnetic force transmitter unit in the setting tool, and then the received waveform is converted into a communication protocol and stored in the tire pressure sensor device. Therefore, the invention not only can achieve the purpose of wireless transmission but also can enhance the stability of signal transmission, eliminate wireless regulatory constraints and improve product quality.

  • Publication number: 20110153248
    Abstract: A method for automatically measuring and quantitatively evaluating the optical quality of an ophthalmic lens, such as, for example, a contact lens. The method measures an ophthalmic lens with an optical phase measurement instrument to derive measured data. The method creates a set of objective optical quality metrics within a computational software. And, the method applies the measured data to at least one of the objective optical quality metrics to determine lens quality.
