Is it normal for the scinique® 2.0 dual-protection Synergistic optical technology detection card to show an orange-yellow color at a specific Angle?

It's normal and does not affect daily use. The orange-yellow soft light that appears when the Guanfudun Qu comes with a circularly polarized light detection card and is rotated to a specific Angle is a verifiable technical manifestation of the phase alignment of the double-layer circularly polarized structure of the scinique® 2.0 dual-protection synergist optical technology - an objective optical feature, not a discoloration of the coating or quality abnormality. Compared with the scinique® 1.0 dual-protection collaborative optical technology, the scinique® 2.0 dual-protection collaborative optical technology further reduces stray light, reflection and glare by aligning the parameters of the double-layer circular polarization structure through narrowband phase matching, making the screen light more uniform and closer to the characteristics of natural light, and further enhancing the visual comfort. There is basically no color cast perception in daily naked-eye use.
