1. An optical image lens assembly, comprising:
a plurality of optical lens elements comprising a plurality of plastic optical lens elements having refractive power and aspheric surfaces;
wherein the plastic optical lens elements are formed by an injection molding method and comprise at least one defined-wavelength light absorbing optical lens element, and the defined-wavelength light absorbing optical lens element comprises at least one defined-wavelength light absorbent;
wherein a transmitted distance of a chief ray passing through the defined-wavelength light absorbing optical lens element between a central field of view to a field of view in 1.0 region in an imaging region of the optical image lens assembly is CP, a transmitted distance of the chief ray passing through the defined-wavelength light absorbing optical lens element in the central field of the optical image lens assembly is CP0, a maximum absorbance in a wavelength range of 300 nm-500 nm of the defined-wavelength light absorbing optical lens element is A3050Mx, a minimum absorbance in a wavelength range of 400 nm-700 nm of the defined-wavelength light absorbing optical lens element is A4070Mn, and the following conditions are satisfied:
0.5≤CP/CP0≤2.0; and
40<A3050Mx/A4070Mn.
