  • Patent number: 12724174
    Abstract: An optical lens structure includes an optical substrate, a predetermined processing area, an optical micro thin film and a micro thin film pattern. The optical substrate has a first surface and a second surface and rays of light passes through the optical substrate. The predetermined processing area is provided on the first surface or the second surface of the optical substrate. The micro thin optical film is formed on the predetermined processing area of the first surface or the second surface by non-contact processing with an ink liquid spot material via nozzles. The micro thin film pattern is formed from the micro thin optical film to thereby provide an optical characteristic.

  • Patent number: 12638617
    Abstract: An optical lens device includes an optical substrate layer, an optical polarization layer and a miniature surface structure. The optical substrate layer has a first surface and a second surface and rays of light passes through the optical substrate layer. The optical polarization layer is provided on the first surface or the second surface of the optical substrate layer. The miniature surface structure is physically processed to form the optical polarization layer and provides a characteristic of optical polarization in the optical polarization layer. The miniature surface structure of the optical polarization layer provides an optical polarization effect to the rays of light while passing through it.

  • Patent number: 12366689
    Abstract: An optical lens device includes an optical substrate layer, an etched miniature-structure polarization layer and an etched miniature surface structure. The optical substrate layer is provided with a first surface and a second surface and a ray of light passes through the optical substrate layer. The etched miniature-structure polarization layer is provided on the first surface or the second surface of the optical substrate layer. The etched miniature surface structure is etched to form the miniature-structure etched polarization layer and provides a characteristic of optical polarization in the etched miniature-structure polarization layer. The etched miniature surface structure of the etched miniature-structure polarization layer provides an effect of optical polarization to the ray of light while passing through it.

  • Publication number: 20040046929
    Abstract: An integrally formed pair of lenses has a curved body and a curved bridge formed on the middle portion to divide the body into two lens portions. The bridge has a radius of curvature different from that of the lens portions so a nose pad can be formed without any additional processes being necessary. Accordingly, the appearance of a pair of glasses with the integrally formed pair of lenses is versatile, and the cost of manufacturing the glasses is reduced.
