A two-side asymmetric light-shift illuminating lens body mainly projecting light from a light emitting device to two asymmetric relative outer directions includes a base having a receiving slot with a downwards opening for receiving a lighting device; a large non-spherical protrusion and a small a large non-spherical protrusion being arranged on two sides of a center light axis on a top surface of the base; a concave curved surface being formed to a border of the two non-spherical protrusions; a concave arc is formed above the receiving slot, outer edge of each non-spherical protrusion being formed with an awl lateral. The awl laterals are gradually narrowed along the projecting direction of the center light axis. An angle between a tangent line of the awl lateral and the center light axis is about 10 degrees.
