An eye glass lens processing apparatus is provided to improve durability and allow for ease of curvature measurement by arranging a lens curvature measuring unit to the apparatus. An eye glass lens processing apparatus comprises a carriage moving together with a lens fixing shaft, a lens rotating motor for rotating the lens fixing shaft; carriage driving units for driving a carriage; and a lens curvature measuring unit(40). The lens curvature measuring unit includes a curvature sensing part(41), a curvature sensing part rotating member(44), and a slider base(43). The curvature sensing part contact one surface of a lens(50), and senses curvature of the lens by moving in left and right directions by the curvature of the lens. The curvature sensing part rotating member moves the curvature sensing part to a curvature measuring position. One end of the curvature sensing part is fitted to the curvature sensing part rotating member. The slider base provides left and right motion trajectories of the curvature sensing part, and provides restoring force in the direction opposite to the movement direction of the curvature sensing part when the curvature sensing part moves in left and right directions by the curvature of the lens, so that the lens and the curvature sensing part tightly contact each other. The curvature sensing part rotating member has a pair of slot forming protrusions(443) and a curvature sensing part rotating motor(440).
