  • Patent number: 11933941
    Abstract: The invention is related to contact lenses that not only comprise the much desired water gradient structural configurations, but also have a minimized uptakes of polycationic antimicrobials and a long-lasting surface hydrophilicity and wettability even after going through a 30-days lens care regime. Because of the water gradient structural configuration and a relatively-thick, extremely-soft and water-rich hydrogel surface layer, a contact lens of the invention can provide superior wearing comfort. Further, a contact lens of the invention is compatible with multipurpose lens care solutions present in the market and can endure the harsh lens care handling conditions (e.g., digital rubbings, accidental inversion of contact lenses, etc.) encountered in a daily lens care regime. As such, they are suitable to be used as weekly- or monthly-disposable water gradient contact lenses.

  • Publication number: 20240085322
    Abstract: The present invention relates to an optical system for triglyceride inspection partially integrated into a toilet seat and comprising a plurality of optical sensor modules and a controlling and processing module, wherein each said optical sensor module comprises a first light source, a second light source and an optical sensor. The optical sensor receives light signals generated by the first and second light sources respectively on the skin of the person (especially the skin of the thighs) to be tested and thereby generates a sensing signal of an adaptive calibration function. The sensing signal is then converted by the controlling and processing module into an inspection value of triglyceride, which is transmitted to a display unit. With the above optical system for triglyceride inspection, triglycerides can be inspected automatically without invasive blood sampling, making the system a convenient home health monitoring device.
