PROBLEM TO BE SOLVED: To provide a lens polishing device and a lens polishing method for efficiently and precisely polishing an optical lens high in face precision. SOLUTION: The lens polishing device 1 is provided with a polishing plate (a polishing part) 3 having a spherical polishing face 3a brought into face contact with a lens 2 to be machined, a holding and pressing part 6 for pressing the lens 2 to be machined against the polishing face 3a while holding the lens 2 to be machined via a lens holder 5, a first oscillating mechanism 8 for oscillating the holding and pressing part 6 around a first oscillating axis C1 passing a spherical center 7 of the polishing face 3a to the polishing plate 3, a second oscillating mechanism 10 for oscillating the polishing plate 3 around a second oscillating axis C2 passing the spherical center 7 to the holding and pressing part 6, a control part 12, which drives the first oscillating mechanism 8 when the spherical center 7 is arranged on the polishing plate 3 side and drives the second oscillating mechanism 10 when the spherical center is arranged on the holding and pressing part 6 side, and a detection sensor (a detection part) 13 for recognizing on which side of the polishing plate 3 side or the holding and pressing part 6 side the spherical center 7 is arranged.
