Zusammenfassung:	Embodiments disclose an optical lens and a light emitting module having the same. The disclosed light emitting module includes: an optical lens including a light-transmitting first body, an incident part including an incident surface and a pattern on a periphery of the incident surface under the first body, and an emitting part protruding from an upper surface of the first body; a light emitting device having a second body having a cavity in which the incident part of the optical lens is disposed, a light emitting diode in the cavity, and a recess in which an outer lower surface of the first body faces a periphery of the cavity; and an adhesive for bonding the outer lower surface of the first body of the optical lens to the recess of the light emitting device, wherein a lower portion of the first body is disposed in the recess.
