Abstract: A lens and a bulb-type light emitting device lamp employing the lens are disclosed. The lens for changing light distribution of incident illumination light and emitting the illumination light includes a light incident surface that is curved, a top surface that is planar and via which at least a portion of light incident via the light incident surface is emitted, and a side surface that is uneven and via which at least a portion of light incident via the light incident surface is emitted. The bulb-type light emitting device lamp includes the lens and a light emitting device package including one or more light emitting devices.
