An eyeglass lens material can be used to make an eyeglass lens and at least includes a mixture of Ag/SiO.sub.x composite nanoparticles and at least one type of monomer. The eyeglass lens is capable of blocking blue light. The monomer undergoes a material curing procedure to form a main body that contains and is mixed with the Ag/SiO.sub.x composite nanoparticles. As the Ag/SiO.sub.x composite nanoparticles in the eyeglass lens material can absorb relatively high-energy blue light, a contact lens made of the eyeglass lens material can block blue light.
