Abstract:
This invention provides a container for a contact lens, comprising: a central recess; a peripheral groove surrounding the central recess; and a rim surrounding the peripheral groove; wherein the central recess is a curved surface having one or a plurality of continuous R values less than an R value of the contact lens in its natural state, and wherein the R value is a radius of curvature of a curved surface.
Abstract:
The present invention discloses a solderable aluminum-based material, wherein electron donors combine with the non-bonded atoms on the surface of an aluminum-based material. The bonding between the electron donors and the aluminum atoms on the surface generates a protective film to prevent from the formation of an aluminum oxide layer on the surface of the aluminum-based material. The present invention improves the conventional aluminum-based material, and has lightweightness, a low price, a high economic value, a high electric conductivity, a high thermal conductivity and a superior solderability. Thereby, a normal soldering, a total-face soldering or a double-side soldering can be easily performed on the solderable aluminum-based material of the present invention with a common soldering technology.
Abstract:
Contact lenses with pores having high oxygen permeability and a manufacturing method thereof. The manufacturing method comprises the steps of uniformly mixing water-soluble salts and the formula of contact lenses having hydrophilic monomers to form a mixed formula; molding and forming the mixed formula to obtain contact lenses; dissolving and dialyzing the water-soluble salts by a water solution so as to form a plurality of pores with a predetermined diameter on a surface and in the interior of the contact lenses. The diameter of pore size has an allowable range between 0.03 μm and 0.05 μm such that the contact lenses with high oxygen permeability can be obtained.
