The popularity of display and artificial lighting has enriched the living environment with blue light.Blue light plays an important role in full-color display and white lighting,but long-term exposure can harm visual safe-ty.Due to the high preparation temperature of anti-blue light film,this paper developed a low-temperature anti-blue light film based on SiO2 and Ag nanoparticles as a low-temperature preparation material.The film filters short-wave blue light and maintains a high transmittance of visible light above 500nm.The results show that the short-wave blue cut-off rate is 53.32％for the films with the ratio of n(Si)∶n(Ag)1∶0.05 in the range of(415～455)nm;In the range of(500～800)nm,the visible light transmittance is 95.08％.Under the condition of 25.8％reduction of blue light damage,the color coordinate shift is only 5％.
