I don't know where the quantum nature of light would come in for sunglasses, but you are correct polarisation would definitely be needed.

- astrange 5y agoIt's claimed that polarization is due to quantum effects. https://www.youtube.com/watch?v=zcqZHYo7ONs https://www.youtube.com/watch?v=zcqZHYo7ONs …I think it actually isn't and the people explaining it have just forgotten it's supposed to be a metaphor though.
- rcxdude 5y agopolarization is very much a quantum effect, however the specific experiment in the video does not prove the quantum wierdness because the setup does allow a hidden variable explanation.
- sharikous 5y agoPolarization of a single photon has to be treated in a QM framework , but there is no need for that with normal sources. Also, polarization as a degree of freedom arises out of symmetry considerations, and that's what you learn in QFT.
