Polarizer can be divided into three types, namely straight polarizers, ellipse polarized and round polarizers.Generally, the so -called polarizer refers to the straight line polarization, also known as flat polarization.The vibration of this light wave is fixed in a specific direction. The transmission route in the space is a sine curve, and the projection on the plane of the vertical dissemination direction is the straight line.
The plane composed of a straight polarized vibration direction and the direction of propagation is called the vibration surface. It is vertically vertically from the vibration direction and the surface of the dissemination direction is called polarizing surface.Make nature light through polarizing mirrors, and can obtain straight -line polarizers, which are often used in crystal optical research.
The classification of polarizer
1. According to the material, it can be divided into: glass mirror of glass material, resin material polarized Sunglasses, and TAC lens material polarized Sunglasses.
2. It can be divided into: Ski mirror, fishing mirror, polarized driving mirror, outdoor sports mirror, golf glasses.
How to distinguish between Sunglasses and polarized Sunglasses
The first is the relationship between the two. The Sunglasses include polarizing mirrors, and polarizing mirrors are a kind of Sunglasses.It should be said that polarizing mirrors are a special Sunglasses designed with more and more requirements and designed.
Then let's talk about the difference. As long as we do not specifically pointed out, we generally have some Sunglasses that only have the two basic functions of obstructing strong light and worry about ultraviolet rays.Such Sunglasses are relatively single, the technical content is lower, and of course the cost is lower. Now many merchants sell ordinary Sunglasses as polarizing Sunglasses, which harms many consumers.
The biggest difference between polarized Sunglasses and ordinary Sunglasses is that this Sunglasses are treated with reflected light.In the environment of our lives, there are three kinds of light: direct light, reflection light, and shot light. Among them, we can not perceive the light shot light, but it is the most important light of our eyes that can see objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see objects.Direct light has a fixed light source (such as the sun), as long as it pays attention, it will not cause harm to our lives.
Only reflected light, because Smooth and flat planes can become reflexes. These common reflexes often reflect light suddenly, which will bring a lot of inconvenience to our lives.For example, driver drivers, the rearview mirror ahead is an uncertain reflective light source. The surface of the road on the road or the Smooth plane objects carried by passers -by can become a reflected light source. These reflex light may bring the driver of the driver.It is dangerous.
Polarized Sunglasses are the glare of reflected, filtering it, so that it can play a role in anti -dizziness, and traveling in summer will make the field of view more clear and reduce visual fatigue.Of course, such Sunglasses will also be much more expensive.
If you just go out, ordinary Sunglasses can fully meet your needs.But whether it is driving or outdoor activities such as mountain climbing and skiing, choosing a pair of polarized Sunglasses will make you easier and more comfortable.
When is it suitable for wearing polarizers
1. fishing
In summer, fishermen like to wear Polarized glasses.Why?The reason is very simple. Polarized Sunglasses have the effect of filter polarizing light. It is easier to wear fishing, and it is easier to watch.It feels more comfortable.
2. Driving
Polarized lenses are the most recognized lenses in the world.When the surface is reflected by the object, it is partially polarized and has a glare.The negative effect of glare -enhances brightness and weakens color saturation; the outline of the object is blurred, making glasses fatigue and discomfort.Polarized tablets make the polarization principle of light, which can effectively eliminate the special functions of glare, filter the messy light, improve the driver's vision and add fun to drive.
3. outdoor sports
Friends who love Outdoor leisure tourism are also exclusive to polarizing lenses. The polarizing mirror is composed of a balanced crystalline. This structure only allows the light waves to balance the crystal, and the light waves that shake to other angles are blocked.If the angle of the polarizer is adjusted, the shocking light reflected by the water surface, glass, flowers, water, water and other reflection can be blocked, and normal light can be partially passed, so as to enhance the contrast, reduce reflection, enhance the color of the scenery, reduce the atmosphere of the atmosphere,The role of fog phenomena makes you see the clearness of the world, and return you a colorful world, a blue sky, strong and beautiful nature.
The lens polarization angle and arc are specially designed and processed. The wearer will not have the feeling of distortion and dizziness of the scene. The resin polarizing lens has the advantages of lightness, difficulty in breaking, and easy to wear and comfortable.It is most suitable for fishing, driving, exercise, navigation, skiing, hunting, etc.
How to buy polarized Sunglasses
1. The first consideration is the quality of polarized Sunglasses
The primary function of polarizing Sunglasses is to prevent ultraviolet rays and filtrate polarized light. Good polarized Sunglasses lenses can block more than 90%of ultraviolet penetration. Please choose polarized Sunglasses with the best blocking of UV400 to the best obstruction of ultraviolet logo;The inferior polarization Sunglasses of the polarizing filtering function, such as dark Sunglasses, is darker with the light of the human eye and the pupils of human eyes will become larger, and the ultraviolet rays of the eyes will increase, increasing damage to human eyes.
2. Will there be discomfort for a long time?
Genuine polarized Sunglasses must be comfortable to wear. If you feel uncomfortable, dizzy, headache, dry eyes, tingling, etc., please take it down quickly;
Meicoscopy belongs to inferior or imitation generally causes dizziness and headaches. Generally, inferior lenses are not technical and functional when manufacturing.The damage can be described as a loss.
3. Focus on the protection function of the frame
The protection function of polarizing Sunglasses Apart from the basic functions such as anti -ultraviolet rays, avoiding strong light dazzling, and filtering glare, most polarizing Sunglasses frames are designed with surface arcs. In outdoor sports, it can effectively prevent wind and foreign body stimulation. In additionThe hardness of the lens and the flexibility of the frame of the frame must be considered whether it will hurt the human body.
4. Polarized Sunglasses should be true and natural
The color selection of polarized Sunglasses should be based on the color of the surrounding environment, the edges of the object are clear, and the principle of effectively identifying different color signal Lights.Especially when driving Sunglasses, it is guaranteed to drive safety.The color of the lens is better in gray, tea, and green, because these colors of lenses are better absorbed by infrared and ultraviolet rays, which can improve visual contrast and clarity. Wearing effects in severe air pollution or fog.
How to identify the quality of polarized Sunglasses
1. Generally, there will be instruments that detect Sunglasses to resist ultraviolet capacity. You can know if the glasses in your hands meet the standard through instrument detection.
2. The simple way to test the quality of the Sunglasses is: you can use the ultraviolet light issued by a banknote pen or a banknote check machine to observe the UV logo pattern on the RMB through Sunglasses. If the quality of the Sunglasses is poor and there is no blocking of ultraviolet rays, it can still be clearly clear.When you see the UV logo pattern on the RMB, on the contrary, if the quality is excellent, you can't see it.
