Abstract
A lens includes a light input surface and a light output surface. The light output surface is opposite to the light input surface. A central region of the light output surface has a plurality of cylindrical surface microstructures. A depth of the cylindrical surface microstructures in a direction parallel to an optical axis of the lens is within a range from 0.02 millimeter to 0.2 millimeter. A vehicle lamp module is also provided.
