Spectroscopy Reveals: The Truth About Blue-Light Blocking
Blue light exposure has become a modern concern—with our screens, phones, and LED lights constantly glowing, questions arise about how best to protect our eyes and sleep cycles. Are blue-light blocking glasses still effective in a world where “Night Mode” settings are standard on every device?
In this Spectra of the Month study, Avantes engineers put these solutions to the test using precise spectroscopic measurements. By comparing the blue-light attenuation of common glasses with a smartphone’s “Night Mode,” this experiment uncovers how each method really performs—and what’s truly happening across the visible spectrum.
Using the AvaSpec-NXS2048CL (Nexos) spectrometer, our team captured real-world data to quantify how much blue light each solution filters, and to explore the optical science behind those coatings and settings.
