  • Publication number: 20240288716
    Abstract: The invention is a virtual reality head-mounted display device with built-in strabismus treatment and operation method thereof. The head-mounted display device detects the motion of the user's eyes to get a compensated angle for strabismus. The processing module can generate a compensated image by a compensated angle for the user. While virtual reality devices are operating, our proposed head-mounted display device automatically detects the movement of the user's eyes and increases or decreases the correction effect of the simulated prism diopter lens. The user uses the device for a long time that can reduce the user's strabismus degree and achieve visual correction and treatment.

  • Publication number: 20230321138
    Abstract: The present invention provides methods of preventing or treating coronavirus infection and reducing coronavirus infection rate in vitro with antiviral composition comprising poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS), wherein the PEDOT:PSS is selected from PEDOT:PSS aqueous solutions in various formulas. Specifically, the molar ratio of PEDOT to PSS in the PEDOT:PSS aqueous solution in the antiviral composition may be 1:1.5 to 1:6 and the resistivity of the PEDOT:PSS aqueous solution in the antiviral composition may be 100 ?/sq to 5×107 ?/sq. The antiviral composition is used to inhibit the binding between the spike protein of the coronavirus and the host cells with angiotensin-converting enzyme 2 (ACE2) on surface. The coronavirus may be SARS-CoV-2.
