What are the benefits of polarizers and the role of polarizers

Benefits: 1. When driving, you will no longer be troubled by many reflections from the sun and the vehicle in front;

2. When skiing, you don't have to worry about reflection and ultraviolet rays, you can glide to your heart's content;

3. When fishing, I don't feel uncomfortable at all, but feel comfortable and dissipated;

4. When it rains, the traffic signs on the road where the rain is flowing are very clear;

5. Ultraviolet rays are effectively blocked.

2.Brown or brown lenses are the first choice for driving because they enhance the contrast of colors.

3.Amber, yellow or orange lenses are ideal for cloudy days and can provide a very clear vision, but are not suitable for use in strong sunlight.

4.Grey or dark green lenses are a good choice for viewing objects in the most natural original color.

5.Sunglasses aren't just for summer, they're actually mandatory all year round. Wear it on sunny days and on cloudy days.

Sunglasses are the ordinary colored glasses that we are usually familiar with for blocking the sun, ordinary sunglasses can only reduce the intensity of light, and can not effectively remove the reflection of the bright surface and the glare in all directions, but in our daily life, in addition to sunlight and ultraviolet rays, light will produce irregular diffuse reflection light through uneven road surfaces, water surfaces and other places, commonly known as "glare". The appearance of glare will cause eye discomfort and fatigue and affect the clarity of vision, bringing a lot of trouble to people's lives and going out, especially the drivers who drive, which are seriously affected.

Due to its high cross-cutting filter layer, the polarizer can effectively filter out all kinds of glare and ultraviolet rays up to 100%, which can not only reduce the light intensity, block the glare, improve the visual contrast, and improve the visual clarity. In the past, polarized lenses were only used for lenses in high-end cameras and cameras due to the manufacturing process, and polarizers were rarely available in sunglasses.

The biggest use of polarizer is to eliminate reflection and make colors more vivid in photography, the principle is to use the characteristics of polarized light (polarized light) to "filter" them with polarized lenses, and then eliminate reflections on water surfaces, glass, non-metallic surfaces, etc., and after removing polarized light, the color will be more intense.

Sunglasses with sunshade function are available to almost all big brands or more reputable brands. The function is very important, but also to find the sunglasses that suit your style, the style you like is the last word, you can go to Xinshixiu sunglasses** to see, it focuses on sunglasses products, it is more detailed, there are many products there, ** is also very cost-effective, I bought it there before.

The principle of polarizers is not the same as that of regular sunglasses. Ordinary sunglasses just add a variety of colors to the lenses to make people less dazzling when they see things in the sun through the lenses, but the sunlight will still shine through the lenses to the eyes, but the color changes to make people feel comfortable. Polarizers, on the other hand, refract the sunlight that enters the lens so that it does not hit the eye.

Polarizers are better than regular sunglasses.

1. Filter the reflected light and increase the imaging contrast.

2. Effectively weaken or eliminate the reflection of non-metallic surfaces, this kind of reflected light is a typical polarized light, and the reflection of metal surfaces is more complex, which is related to the incident wavelength and surface roughness.

3. Improve the image quality of the subject and improve the clarity of the picture. For example, by using a polarizer, you can reduce the reflection on the surface of the water, so that you can clearly capture the fish in the water.

4. The polarizer can effectively improve the saturation of the color and improve the contrast, because the polarizer can absorb the stray light reflected by the fog or dust in the atmosphere in various directions, so as to make the image more pure.

5. When taking landscape photos, it has an excellent effect on the depiction of clouds.

1. Polarizer: The full name is Duanchai Polarized Light Lens, referred to as PL Mirror, also known as Polarizer, which is a lens composed of a balanced arrangement of crystals, and the crystal structure only allows the light waves that are balanced with the crystal to pass through, and the light waves that vibrate at other angles are all blocked and cannot pass through;

2. The function of polarizer: it is mainly used to absorb polarized light in the sky, reflection on the water surface, glass reflection and other non-metallic reflections;

3. According to the principles of modern physics, natural light transmits wisdom in the form of wave energy, and relative to the propagation direction of light, the direction of light wave vibration is in all directions.
