A method of manufacturing a colored lens comprising:
(i) applying a coating liquid for forming a dyeable hard coat layer onto a lens substrate, or indirectly onto the lens substrate by interposing another layer therebetween;
(ii) heating the lens substrate coated with the coating liquid in a first heating step at a temperature of T 1 °C for t 1 hours to form a semi-cured hard coat layer formed on the lens substrate;
(iii) dyeing the semi-cured hard coat layer by dipping it in a dyeing liquid; and
(iv) heating the lens substrate on which the dyed, semi-cured hard coat layer is formed in a second heating step at a temperature of T 2 °C for t 2 hours to form a completely cured hard coat layer,
wherein the following expression is satisfied when the product of the temperature T 1 (°C) and the time t 1 (hours) is a first management value Q1 and the product of the temperature T 2 (°C) and the time t 2 (hours) is a second management value Q2: 0.2 < Q �¢ 1 / Q �¢ 1 + Q �¢ 2 ‰¤ 0.5.
