Can you see a rainbow with polarized sunglasses?

Can you see a rainbow with polarized sunglasses?

In the previous article, we discussed “Do you know about sunglasses with prescriptions?”. In this article, let’s talk about “Can you see a rainbow with polarized sunglasses?”.

Why can't I see my phone screen with polarized sunglasses?

This is the polarization phenomenon. The polarizing direction of the sunglasses and the phone screen is not the same, which causes the light you see to be slightly different in tone and to increase or decrease some of the light. Theoretically, there is a reason for light interference. Light interferes with the surface of your sunglasses, and the phone screen is all plastic. It's not a quality problem at all. It's the properties of the polarized lens.

Why do I see rainbows in car windows with polarized sunglasses?

The color spectrum that your polarized lens sees is caused by sunlight hitting the film on the windshield. It is supposed to study the film you stick, because it is not flat, or the quality of the film is not good.(https://www.koalaeye.com/collections/polarized-sunglasses)

Why do polarized sunglasses make glass look weird?

Car glass is coated, so when you look at something with a polarized lens, you can see something that you can't see with the naked eye. Car film is usually a metal film, and there is a layer of the metal layer. With a polarizer, there will be some color stripes or color light. Polarized sunglasses selectively absorb some of the wavelengths that make up the sun's rays because they use fine metallic powders (iron, copper, nickel, etc.). In reality, when light passes through the lens, it is subtracted by a process called destructive interference. The phenomenon of destructive interference depends on the refractive index of the lens. Generally speaking, the thickness does not vary much, while the refractive coefficient of the lens varies according to the chemical composition.

Things to consider when choosing sunglasses.

Hold the corners of the sunglasses against the fluorescent lamp and let the reflective strip of the lens roll gently. If you find that the reflection of the sun's light looks wavy and distorted, it shows that the lens is not smooth. Such a lens can damage your vision. Lenses should be flat and have high transparency. Lens materials have glass and resin, and the best lens should be polarized lenses. It is made of seven thin sheets, with the outer two layers of a super hard wear-resistant layer. The second and sixth layers are shatter-proof strengthening layers. The third and fifth layers are the ultraviolet filter layer, and the middle layer is the polarized filter layer.
