1 定义
偏光，英文名称polarized light
Translation: Polarized light is also known as polarized light. Visible light is a transverse wave, with its vibration direction being perpendicular to the direction of propagation. The vibration direction of natural light is arbitrary within the plane perpendicular to the direction of propagation; for polarized light, its vibration direction is restricted to a specific direction at a certain moment.
2 Features
In life, there are too many sources of light that produce harmful rays, especially sunlight; the light emitted from sunlight includes: visible light, "InfraredandultravioletThere are three types of harmful rays: ultraviolet rays, visible light rays (310 to 780 nanometers), and blue light. Among them, ultraviolet rays can cause serious damage to the skin and eyes of the human body. Ultraviolet rays are further divided into UVA, UVB, and UVC (above 310 nanometers), with blue light being one of them. Among these, UVA, UVB, and UVC are harmful rays. If exposed to them for a long time, they will cause damage to the body. UVB has a serious impact on vision, and tanning rays are the light that burns the skin. Most of the corners of the eyes will absorb this UVB light, so it is very important to block this light source. Polarized sunglasses, because they have the function of polarizing light, can block all harmful rays without affecting the transmission of visible light, and can truly achieve the function of protecting the eyes. In addition to the basic function of preventing ultraviolet rays, polarized sunglasses also have the functions of anti-glare, road surface reflection, and water surface glare, making them suitable for driving, fishing, traveling, and daily wear.
3 制作原理
Polarized sunglasses can block uncomfortable bright light and protect the eyes from the harm of ultraviolet rays. All of this is thanks to the metal powder filtering device, which can "select" the light as it enters. Polarized sunglasses can selectively absorb certain wavelengths of light that make up sunlight because they use very fine metal powder.ironCopper,nickel等）。事实上，当光线照到镜片上时，基于所谓"相消干涉”过程，光线就被消减了。也就是说，当某些波长的光线（这里指的是紫外线a，紫外线b，有时还有InfraredWhen light passes through a lens, it will cancel each other out on the inside of the lens, which is the direction towards the eyes. The overlapping of light waves is not a random phenomenon: when a wave's peak combines with the valley of the adjacent wave, it leads to mutual cancellation. The phenomenon of mutually canceling interference depends on the lens's "Refractive Index（即光线从空气中穿过不同物质时发生偏离的程度），还取决于镜片的ThicknessGenerally speaking, the thickness of the lens does not vary much, while the refractive index of the lens varies according to the differences in chemical composition.
Polarized sunglasses provide another mechanism for protecting the eyes.Asphalt roadThe reflected light is a special type of polarized light. The difference between this reflected light and the light that comes directly from the sun or any artificial light source lies in the issue of order. Polarized light is formed by waves that vibrate entirely in one direction, while ordinary light is composed of waves that vibrate randomly. This is akin to a group of people walking aimlessly compared to a group of soldiers marching in unison, creating a stark contrast. Generally speaking, reflected light is a form of ordered light. Polarized lenses are particularly effective at blocking this type of light because their filtering properties are at work. These lenses allow only polarized waves that vibrate in a certain direction to pass through, as if they have "combed" the light. For roadway reflection issues,
Using polarized sunglasses reduces light transmission because it prevents light waves that are vibrating parallel to the road from passing through. In fact, the long molecules in the filtering layer are oriented horizontally, which can absorb light of horizontal polarization. This way, most of the reflected light is eliminated, and the overall illumination of the surrounding environment is not reduced.
Finally, polarized sunglasses lenses darken when sunlight hits them. When the light diminishes, they become bright again. This is possible because Silver halidecrystalline substance is at work. Under normal circumstances, it enables the lenses to maintain perfect transparency. When exposed to sunlight, silver within the crystals separates, and free-floating silver forms small aggregates within the lens. These small silver aggregates are irregular, jagged blocks that do not allow light to pass through but only absorb it, resulting in the lenses becoming darker. In low-light conditions, crystalThe lens then returns to its bright state as the reformation is completed.
4鉴别UV (UV Protection Level)
UVThe meaning of "standard" refers to the range of light perception by the human eye, which is 380~780nm (visible light), while ultraviolet light refers to light with a wavelength below 380nm (invisible light). The meaning of "UV380" is that it can effectively block light with a wavelength below 380nm. The "UV400" standard, however, because it also blocks some visible light, will result in a loss of some colors.Polarized light (polarized light, polarized filter)
Color saturationThe polarized lens makes the outline of the object blurry, causing eye fatigue and discomfort. The polarized filter is made based on the principle of polarized light, that is, when the vibration plane of light is parallel to the polarization axis, the polarized light filter can allow polarized light to pass (like the principle of venetian blinds). Therefore, the light is sorted into light entering the eye in the same direction, making the surrounding scenery look clear without being eye-piercing. Another outstanding advantage of this film is that it is extremely light and thin (thickness of 0.8mm, 1.1mm), and it is very durable, so this kind of lens is very suitable for wearing when driving and participating in outdoor activities. In recent years, it has received wide favor.
Drivers tend to prefer polarized sunglasses because polarized lenses not only blockultravioletIn addition, it can greatly reduce and filter out the strong glare from reflected light. For example, when driving, the strong headlights of the oncoming car, or the strong glare formed by the sun shining on the UV blocking window film attached to the rear window of the car in front, can make the wearer clearly see the things in front.
5 distinctions
General sunglasses are merely used for reducing light intensity, as ordinary lenses cannot filter out light, so they can only reduce the intensity of glare, UV light, and so on, and cannot completely block these harmful rays. Therefore, their function is merely to reduce the damage to the eyes, but the advantage of general sunglasses is good popularity. Polarized lenses, due to their polarized nature, can completely block the annoying glare caused by scattering, refraction, and reflection. At the same time, they can also completely block the harmful UV light that affects the eyes, making it easier for people to avoid eye fatigue when working under strong light for a long time, achieving true protection. Moreover, it can make the things seen clearer and more three-dimensional.
6 categories
Polarized sunglasses can be categorized based on their use as:ski goggles,Fishing mirrorPolarized driving glasses, outdoor sports glasses, golf sunglasses.
Polarized sunglasses can be classified according to their materials into: glass polarized sunglasses, resin polarized sunglasses, and TAC lens polarized sunglasses.
7 applications
In summer, anglers all like to wear polarized sunglasses. Why? The reason is very simple. Polarized sunglasses have the function of filtering polarized light, and wearing them while fishing makes it easier to see the float and feels less tired. If the lens color is dark (such as brown, green gray, etc.), it feels more comfortable to wear in summer.
Polarized lenses are globally recognized as suitable for driving. Light that is reflected from objects has already been partially polarized, resulting in glare. The opposite effect of glare is to enhance brightness and reduce color saturation; it makes object outlines blurry and causes eye strain and discomfort. Polarized lenses are made based on the principle of light polarization, which have a special function to eliminate glare, filter chaotic light, and improve vision for drivers, adding to the enjoyment of driving.
Friends who enjoy outdoor leisure travel are also fond of polarized lenses. Polarized lenses are composed of a balanced arrangement of crystals. This structure allows only light waves that are in balance with the crystals to pass, while light waves that vibrate at other angles are blocked. If the angle of the polarized lens is adjusted properly, the reflected polarized light from the water surface, glass, plants, and moisture can be blocked, while normal light can pass through partially, thereby enhancing contrast, reducing reflection, enhancing the color of the scenery, and reducing the phenomenon of atmospheric fog, allowing you to see the world clearly and return you a colorful world, a bluer sky, and a rich and beautiful nature.
The polarized angle and curve of the lenses are professionally designed and processed, so wearers will not experience distortion of the scenery or dizziness. Resin polarized lenses are lightweight and less likely to break, making them comfortable and easy to wear. They are suitable for activities such as fishing, driving, sports, sailing, skiing, hunting, etc.
