SURFACE TREATMENT DEVICE FOR SPECTACLE LENS AND METHOD FOR MANUFACTURING SPECTACLE LENS

摘要

PROBLEM TO BE SOLVED: To reduce both of generation of failures such as color irregularity due to uneven temperature of a process liquid and generation of failures such as a color void caused by deposition of bubbles induced by use of a stirrer.SOLUTION: A dyeing treatment device for a spectacle lens includes: a dyeing tank 2 for reserving a dyeing solution to be used for the dyeing process of a spectacle lens L; a heater 3 for heating a bottom plate 4 of the dyeing tank 2; and a convection promoting member 10 which has a partition 11 segmenting the inside of the dyeing tank 2 into a first region E1 to be used for immersing the spectacle lens L and a second region E2 nearer to the bottom plate 4 of the dyeing tank 2 than the first region E1, and which promotes a heating convection of the dyeing solution by the heater 3.
