PROBLEM TO BE SOLVED: To provide a method for stably manufacturing a dyed optical lens for a long period of time, the lens having a silicone-based functional film on a surface of a plastic lens, suppressing an uneven dyed condition and having high scratch resistance.SOLUTION: The method for manufacturing a dyed optical lens comprises dying an optical lens having a silicone-based functional film on a surface of a plastic lens; and the method includes a step of dyeing the optical lens by immersing the optical lens in a water dispersion, which includes a dye insoluble or substantially insoluble with water dispersed therein, contains a buffer solution component and has a pH of 6.6 to 7.5. |
