Maybe slightly off topic but I was surprised to discover that my glasses with photoreactive lenses (SpecSavers ‘Reactions’) are actually circularly polarised but only when they go dark. I originally thought they didn’t work because they didn’t interact with another pair of polarised sunglasses (no changing brightness as I rotated one lens in front of the other) but later noticed that my phone screen with its circularly polarised IPS screen was almost black in bright sunlight… until I took my glasses off. |
