  • Publication number: 20240111178
    Abstract: A contact lens comprises an optical zone and a peripheral zone. The optical zone is used for vision correction. The peripheral zone surrounds the optical zone. The optical zone and the peripheral zone jointly define a geometric center and a horizontal axis passing through the geometric center. Two stabilization zones symmetrically arranged relative to the geometric center are formed in the peripheral zone. These stabilization zones gradually thicken relative to a base curved surface of the peripheral zone.

  • Publication number: 20240114207
    Abstract: A media docking device includes an input module, an output module and a processing module. The input module is electrically connected to a media source device for receiving media data. The output module is electrically connected to a media play device. The processing module determines if an instruction is received from the media source device or a remote device. If the instruction is not received, the processing module transfers the media data to the output module to transmit to the media play device. If the instruction is received, the processing module limits a transmission of the media data according to the instruction, such that the media data will not be completely played by the media play device.
