Is the glass blue or green? -Anjuke Real Estate Q&A

Green film is a more advanced and complicated film system than blue film, with wider and flatter antireflection passband and antireflection valley in the center of visible spectrum. The green film has better anti-reflection performance and the blue film has better anti-radiation performance. The light transmittance of green film is high, reaching 98.6%. The light transmittance of blue film is not as good as that of green film. The light transmittance of the blue film reaches 96.8%. This is the contrast of light transmittance. Secondly, if the wear resistance is compared, the wear resistance of the blue film is better than that of the green film. So it depends on which property of glass you value more.
