Polarizing lens made of aromatic polycarbonate

A method for producing a polarizing lens, the method comprising:

• (a) bending a polarizing sheet onto a spherical or aspherical surface, wherein the polarizing sheet comprises (i) a polarizing film and (ii) two aromatic polycarbonate sheets comprising a first aromatic polycarbonate, wherein a first of the two aromatic polycarbonate sheets is bonded via an adhesive layer to a first surface of the polarizing film, and a second of the two aromatic polycarbonate sheets is bonded via an adhesive layer to a second surface of the polarizing film;
• (b) injecting a second aromatic polycarbonate onto one surface of the bent polarizing sheet;
• and then (c) heat treating the bent polarizing sheet at a temperature in a range from 15° C. less than to 40° C. less than a glass transition temperature of the first aromatic polycarbonate;
• to obtain a polarizing lens,
• wherein:
• a retardation value of the aromatic polycarbonate sheet disposed on an opposite surface to the surface where the second aromatic polycarbonate was injected is in a range from 2000 nm to 20000 nm.
