A camera lens for decreasing aberration is provided to correct the aberration of transmitted light efficiently by having a plurality of thin films which has reflectivity different depending on a bend radius of a lens body, thereby having advantages of both a spherical lens and an aspheric lens. A camera lens for decreasing aberration includes a lens body(1). A plurality of thin film layers(2) are attached on a surface of the lens body. The thin film layers have various refractive indexes to compensate aberration of transmitted light. The thin film layers are attached on a surface of the lens body by arranging with a concentric circle shape. Each refractive index of the thin film layers attached at a center portion of the lens body is higher than that of thin film layers attached at a periphery portion of the lens body. |
