A lens is provided in an asymmetric shape including at least two curved surfaces with different light distribution angles. Therefore, uniformity ratio of illuminance and coefficient of utilization (CU) may be increased while reducing dazzle. When a lighting apparatus including the lens is used as a street light, light directly incident to a driver is minimized, thereby reducing dazzle to the driver. During a night drive, brightness at a far forward position of the driver may be increased. In addition, light emitted toward a street may be increased while reducing light emitted toward a sidewalk. As a result, uniformity ratio of illuminance and coefficient of utilization (CU) may be increased. Also, light pollution may be reduced.
