Is it advisable to wear sunglasses while driving?

You can wear sunglasses when driving, but polarized glasses will be more effective.

The function of a polarizer is to filter reflected light and increase imaging contrast. It works by selectively filtering light coming from a certain direction. By filtering out much of the polarized light in diffuse reflection, it reduces the intensity of light in the sky, darkens the sky, and increases the contrast between blue sky and white clouds. When actually shooting, you need to look at the viewfinder and rotate the front mirror. The effect is most obvious when the sky is darkest in the viewfinder, and the darkest and darkest contrast is 90 degrees. You can turn it to any angle between darkest and brightest as needed.

Polarizers can also effectively reduce or eliminate reflections from non-metallic surfaces. This reflected light is typical polarized light (the light reflected back from metal surfaces is not polarized light, and polarizers have no effect on it). By adjusting the polarizer, you can filter out this part of the reflection, thereby improving the image quality of the subject and increasing the clarity of the image. For example, by using a polarizer, you can reduce the reflection on the water surface, allowing you to clearly capture fish in the water. When shooting such a scene, the projection angle of the light source should be close to the angle of the camera, and its maximum deflection angle should be between 30 and 40 degrees. When using it, you can adjust it by slowly turning the lenses in the front group of the filter to minimize the reflection on the surface of the scene. In addition, polarizers can effectively increase color saturation and contrast. This is because polarizers can absorb stray light from various directions reflected by fog or dust in the atmosphere, making the captured images purer. For example, in photography such as flower still life photography, polarizers are often used to take colorful photos. It is useful in landscape photography, flower photography, and shooting of certain highly reflective scenes. Polarizers are used when taking landscape photos, and have excellent effects on the depiction of clouds. The refractive index of light in the blue sky is greater than that of light scattered by white clouds. Using a polarizer can also make the colors of green leaves more saturated and eliminate the haze in low-angle shots of city scenes.
