  • Polarizing lens constituted of aromatic polycarbonate
    Patent number: 9063276
    Abstract: Provided is a polarizing lens which is excellent especially in terms of impact resistance, appearance, and prevention of eye strain and which has high precision of the surface shape. The polarizing lens is formed by laminating a sheet of an aromatic polycarbonate through an adhesive layer to each surface of a film having polarizing properties, curving the resultant laminate so as to impart spherical or aspherical surfaces thereto to obtain a polarizing sheet, inserting the polarizing sheet into a mold, and injecting an aromatic polycarbonate, wherein the polarizing sheet is obtained through the laminating so that the stretch axis of one of the aromatic-polycarbonate sheets is perpendicular to the absorption axis of the film having the polarizing properties.
