  • Publication number: 20250018667
    Abstract: A moisturized contact lens and a method of manufacturing the same are provided. A lens of at least one quasi-contact lens is placed on a pallet of a modification processing machine for contact lenses. Then an electric arc generating unit is driven by a feed unit of the modification processing machine for contact lenses to remove impurities clogged pores of a lens of the quasi-contact lens and form circular grooves on surface of the lens of the quasi-contact lens. Thereby breathability, oxygen permeability, and hydrophilicity of the contact lens are restored. The circular grooves are for storage of tears so that wettability between eyeballs and the contact lens can be maintained for a long time and tear circulation is improved. Users won't have discomfort and dry eyes caused by insufficient moisture even wearing the contact lens for a long time and eye drops or artificial tears are not used.

  • Patent number: 12092901
    Abstract: An eyeglasses assembly structure is revealed. A pivot member which is pivotally connected to a first assembly portion of a frame is inserted and mounted in a switch member. A first rib and a second rib are opposite to each other and disposed on a second assembly portion at a front side of a temple. The first rib is mounted into a first mounting groove at one end of the pivot member. A positioning flange is formed on the second rib and inserted through an opening of the switch member to be mounted in a second mounting groove on the other end of the pivot member. When the switch member is rotated an angle to be staggered or aligned with respect to the positioning flange of the second rib, the temple is firmly fixed to or separated from the frame. Thereby parts are assembled and replaced easily and conveniently.
