Abstract
An optical image lens assembly includes at least one optical lens element which is made of a plastic material and includes at least one short-wavelength light absorbing agent. The short-wavelength light absorbing agent is homogeneously mixed with the plastic material. The optical lens element including the short-wavelength light absorbing agent has refractive power, and at least one of the object-side surface and the image-side surface of the optical lens element including the short-wavelength light absorbing agent is aspheric.
