Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ophthalmic lens where the contact boundary between a transparent lens and a lens for hypermetropia is smoothly curved to eliminate a difference in thickness like a step. SOLUTION: This ophthalmic lens 1 is provided with a transparent lens 11 and a lens 12 for hypermetropia, and the lens 12 is connected to the lower end of the transparent lens 11, and the lens 12 is smoothly curved from the lower end of the transparent lens 11 and is extended downward, and a contact boundary 13 between the transparent lens 11 and the lens 12 is inclined and connected not to form a difference in thickness like a step, and therefore, a trouble of sight doesn't occur.
