Abstract: A coating composition capable of forming a hard coat layer having excellent adhesion and scratch resistance; a spectacle lens; and a method for producing a spectacle lens. A coating composition containing hydrophobic inorganic oxide particles; a silane coupling agent; and a cationic photopolymerization initiator. A spectacle lens including a hard coat layer obtained by curing the coating composition; and a substrate and a method for producing a spectacle lens, including a step of applying the coating composition onto a substrate; and a step of curing the applied coating composition by irradiating the coating composition with light.
