    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.
