A contact lens and a manufacturing method thereof are proposed. The contact lens may include a resin composition containing an acrylic-based monomer and a Boswellia extract. By containing a Boswellia extract, the contact lens can prevent adherence of bacteria when worn on the user's eye and serve as an antibacterial agent to prevent bacterial infection, so it can secure a good contact fit and high antibacterial performance.
