PURPOSE: A polarizing lens manufacturing method is provided to use a primer which does not include a solvent, thereby improving the stability and reliability of a polarizing lens. CONSTITUTION: A polarizing sheet is manufactured by adhering a triacetyl cellulose film to one side or both sides of an extended polyvinyl alcohol film (S101). Both sides of the polarizing sheet is coated with a primer using a micro gravure coating method (S103). The polarizing sheet which is coated is shaped into a lens shape (S105). After the polarizing sheet having the lens shape is inserted and fixed to a mold for casting, a CR-39 resin is bonded by injecting a mixture of the CR-39 resin and a thermosetting material (S107).
