An exemplary composite lens includes a main body and an embedding member. The main body has a first surface and an opposite second surface. The main body has an optical axis associated therewith. The embedding member is disposed in the main body between the first surface and the second surface. A main plane of the embedding member is perpendicular to the optical axis of the main body. A refractive index of a material of the embedding member is higher than that of the main body. The composite lenses can be made thinner. A method for manufacturing the composite lens is also provided.
