What are the classification of polarizing mirror

1. According to use

skiing mirror: You don't have to worry about reflective and ultraviolet rays, you can skate it;

fishing mirror: The water wave shines under the sun, but you will not feel uncomfortable at all, but feel comfortable and easy;

Polarized driving mirror: no more reflective troubles from the sun and the vehicles in front of the vehicle;

outdoor sports mirror: During vacation, let you enjoy the sun, beach and leisure time;

golf glasses: Don't worry about the dazzling sunlight, let you perform golf skills on the lawn.

2. According to the material

glass material: Hardness is high, scratches are not easy to appear, the impact resistance is poor, it is easy to break after being impacted, and the weight is heavier.

Resin material: very light, high -temperature resistant, resistance to impact, and can effectively block ultraviolet rays and see things clearer.

TAC lens material: effectively reduce strong light, the vision is clearer and soft, clear, will not be distorted or dizzy of the wearer.

3. According to the principle

Round polarizer (referred to as CPL)

Linear polarizer (referred to as LPL)

LPL is mainly used for old -fashioned manual focus cameras.The late CPL adds a layer of 1/4 wavelength film. This film has a special nature that can generate /2 phase shifts in one direction (assuming X) polarizing electrical vector, and vertically with it to be vertical with itThe electrical vector of the direction (assuming to y) has no effect.Therefore, the direction of the angle level of the above polarized light along X and Y can pass through 1/4 waves, so the light of the outlet is that there are two polarizing directions perpendicular to the light, and the polarized light of the phase difference /2 is synthesized, which is so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -calledThe round is biased.This design makes it more suitable for new automatic focus and automatic exposure cameras.The camera currently using AF lens (switching camera lens with automatic focus function) uses CPL as polarizing mirrors.Under some light conditions, a linear polarizer may mislead the light metering element in the aircraft to merge, so the DC and most automatic focus cameras use round polarizers.

4. Press color

Light red or vermilion: In the case of glare, it can deepen the contrast and sharpness, which is very suitable for water activities and snow activities.

Brown or brown: It can enhance the contrast of color, so it becomes the first lens when driving.

Amber, yellow or orange: It is very suitable for wearing in cloudy days. It can have a very clear field of vision, but it is not suitable for strong use in the sun.

Gray or dark green: It can maintain the most natural original color when visually, which is a good choice.

What are the characteristics of all types of polarizing mirrors

According to the different mechanism of filter polarization, polarizers can be divided into two types: round polarizer (CPL) and linear polarizer (LPL). These two functions are the same.LPL is mainly used for old -fashioned manual focus cameras.The late CPL adds a layer of 1/4 wavelength film. This film has a special nature that can generate /2 phase shifts in one direction (assuming X) polarizing electrical vector, and vertically with it to be vertical with itThe electrical vector of the direction (assuming to y) has no effect.Therefore, the direction of the angle level of the above polarized light along X and Y through the direction of the lines of X and Y can pass through 1/4 waves, so the outlet of the light is that there are two polarizing directions perpendicular to the light, and the polarized light of the phase difference /2 is synthesized, which is so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -calledThe round is biased.This design makes it more suitable for new automatic focus and automatic exposure cameras.The camera currently using AF lens (switching camera lens with automatic focus function) uses CPL as polarizing mirrors.Under some light conditions, a linear polarizer may mislead the light metering element in the aircraft to merge, so the DC and most automatic focus cameras use round polarizers.

The role of the PL mirror is to filter reflective light to increase the contrast of imaging.Its working principle is to selectively filter light from a certain direction.By filtering the many biased Lights in the long reflection, weaken the intensity of light in the sky, darke the sky, and increase the contrast between the blue sky and the white clouds.When you shoot the specific real shooting, you should look at the viewfinder and rotate the front mirror. The darkest effect in the sky in the viewfinder is the most obvious, and the darkest is 90 degrees.You can transfer to any angle of the darkest and the brightest rooms as needed.

PL mirrors can also effectively weaken or eliminate non -metallic surface reflection. This reflection light is a typical polarizing light (the light reflected by the metal surface reflection is not polarized light, and the Polarized mirror does not work on it). By adjusting the polarizer, you can filter it by adjusting the mirror.The reflection of this part is dropped, thereby improving the image quality of the subject and improving the clarity of the picture.For example, by using polarizers, the reflection of the water surface can be weakened to clearly shoot the fish in the water.When shooting such a scene, the projection angle of the light source should be consistent with the angle of the camera, and its maximum partial angle needs to be agreed between 30 and 40 degrees.When using it, you can adjust the lens in the front group of the filter to minimize the reflection on the surface of the scene.

In addition, polarizing mirrors can effectively improve the saturation of color and increase contrast. This is because polarizing mirrors can absorb various directions reflected by fog or dust reflected in the atmosphere, so that the shooting images are more pure.For example, in photography such as flowers and static objects, polarizers are often used to take colorful photos.It is useful when landscape photography, flower photography and shooting certain specific reflective scenes.The polarizer is used in the landscape photo, and the depiction of the cloud layer has excellent effects.The light refractive index of the blue sky is greater than the light scattered by the white clouds.Using polarizer can also make the color of green leaves more saturated and eliminate the fog of shooting urban scenery at low angles.

Is Polarized glasses anti -ultraviolet rays?

Polarized mirrors can prevent ultraviolet rays, but the protection capacity is weak.

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 rays.UV prevention effects with polarized Sunglasses with "UV400" are the best effect.

The polarizing mirror is a lens manufactured according to the polarization principle of light. It can exclude and filter the scattered light in the beam, and anti -ultraviolet rays and filtration polarized light.A good polarizing mirror can achieve the color of the surrounding environment, the edges of the object are clear, can effectively identify different color signal Lights, and reduce the ultraviolet rays that are irradiated into pupils.

The Polarized mirror is better than the shutters, but it only blocked some light, and the light (including ultraviolet rays) that is basically parallel to the polarization angle of the polarization is still released. From the perspective of protection, it is equivalent to adding a layer of soft gauze to the window., It's just partially blocked.The biggest advantage of polarizing mirror is to block the glare interference and make the visual effect more clear, and the protection of ultraviolet rays is not as good as reflective Sunglasses and color transformer mirrors.

How to judge whether polarizing Sunglasses have anti -ultraviolet function

1. Look at the label

Obvious signs such as "UV" and "UV400" are seen on Sunglasses labels or lenses on UV prevention.The "UV Index" is also the effect of filtering from ultraviolet rays. This is a very important standard for buying Sunglasses.The light of the wavelength at 286nm-400nm is called ultraviolet rays. Generally speaking, 100%UV index is impossible. Most Sunglasses of the UV index are between 96%and 98%.

There are Sunglasses with anti -ultraviolet function, generally there are several clear ways:

(1) Mark the "UV400": This means that the lens cuts the wavelength of ultraviolet is 400nm, that is, the maximum value of the maximum value of the spectral ratio of less than 400nm in the wavelength () is not greater than 2%.

(2) Mark the "UV" and "UV": This means that the lens's deadline for UV is 380nm, that is, the maximum value of the maximum value of the spectral ratio of the spectral ratio below 380nm below 380nm is not more than 2%.

(3) Mark "100%UV absorption": This means that the lens has a 100%absorption function on ultraviolet rays, that is, its average transmission ratio in the ultraviolet interval is not more than 0.5%.

The Sunglasses that meet the above requirements are Sunglasses that truly have protection for ultraviolet rays.

2. Use banknotes to verify

In the absence of instruments, ordinary people can also detect whether Sunglasses have the function of anti -ultraviolet rays.Take a banknote, put the Sunglasses lens on the anti -counterfeiting watermark, and use the banknote pen or the banknote inspection machine to take a look at the lens.This pair of sun mirrors is anti -ultraviolet.

What color is good for driving the lens?

1. Gray lens: It can absorb various Lights balancedly, and it will darker when watching the scene, but there will be no obvious color difference, which can show a real and natural feeling, which is a neutral color system.

2. Tea -colored lenses: filtering out a large amount of blue light can improve visual contrast and clarity, and it is better to wear in the case of severe air pollution or fog.

3. Green lens: While absorbing light, it can maximize the green light of the eyes, suitable for people who are easy to fatigue.

4. Yellow lenses: Yellow lenses can hardly reduce visible light, but when fog and dusk, yellow lenses can improve visual contrast and make people look more clear.

5. Light blue/light pink lenses: Light blue, light pink lenses are more decorative lenses, and the filtering effect is often unsatisfactory.

6. Black tea fillets: Suitable for patients with retinal pigment transgender, and also suitable for drivers to wear during the day.

From the comparison of the color of the lens above, it can be seen that the color of the most suitable for driving Sunglasses is black tea -colored lenses. If the driver thinks that he is not suitable for black tea -colored lenses, the light -lighter lenses can also be worn.Finally, it is recommended that if you can drive the problem of the sun's dazzling problems without driving without Sunglasses, it is best not to wear Sunglasses.Because Sunglasses can effectively reduce light affecting people's eyes, it will have more or less impact on vision, and driving is a high -risk behavior.

Drive the driver's glasses and drive to avoid 4 misunderstandings

The small pair of Sunglasses, inaccurate wear, can also cause accidents. This detail usually does not pay much attention.So, how to choose Sunglasses when driving to help driving safety?Pay attention to avoid these four misunderstandings:

Misunderstanding 1: The darker the color, the better

Many people take it for granted that the deeper the color, the better the ultraviolet function.In fact, the function of Sunglasses filtering ultraviolet rays is only related to the plated membrane, and the color is not deeper, the better.Especially for the long -distance driver, if the Sunglasses we wear are too darker, the eyes are more prone to fatigue, and it is more dangerous to enter the tunnel and other Lights from strong sunlight.

Misunderstanding 2: Polarized lens is the most comfortable

Many drivers like to wear polarizing mirrors, which can effectively filter to remove glare Sunglasses.Eyring can make people's eye discomfort and fatigue, and affect the clear vision, so many drivers feel the most comfortable to wear polarizers.In fact, polarizers are more suitable for fishing, skiing or water exercise.Especially the cheap polarizer, watching things deform through the windshield of the car, is more likely to cause accidents.If you must wear polarizers, you must choose good quality optical lenses.The polarizer of tens of yuan can't be worn by driving.

If the driver likes the comfort of the polarizing mirror to prevent glare, it is recommended that the silver film lens looks like a mirror. It has a strong anti -glare function and is suitable for driving.

Misunderstanding 3: Do not wear myopia mirrors

Some drivers are slightly myopia, and they usually don't wear myopia mirrors when they are driving.But once you put on Sunglasses, the problem comes: the eyes are more prone to fatigue, the vision will decrease, just as it will be affected by driving vision at night.Therefore, the driver of slight myopia usually has no problem with driving. If you want to wear Sunglasses, you must be equipped with a lens with myopia.

Misunderstanding 4: Five colorful pursuit of fashion

Fashionable young people will have a variety of colors of Sunglasses and use them with clothes.Many beautiful Sunglasses are not as good as wearing when playing, but it should not be used when driving.

What is polarizing mirror

The word "polarizing light" comes from physics. The reflection on the non -metal surface of glass and water surface is polarized light, and the clear blue sky is also polarized in the scattered light in the direction of 90 with the sun.These Lights need to be avoided, eliminating polarizing light, which can make the color of the sky deeper and effectively reduce the impact of glare on photos.The polarizing mirror uses the grating principle to eliminate polarized light at a certain angle.Here you need to pay attention to the angle of shooting. When the backlight or Smooth light shooting, the role of polarizing mirror is limited, and it must be a certain angle with the light source and reflector.

What is the role of polarizing mirror

The photos can look more transparent and the color is brighter.It can also be darkened in the sky, eliminate reflection, and it is very useful when shooting water flow and glass.Polarized mirror can also play a role in blocking light, which can reduce the shutter speed.To understand the use of polarizers, you need to master certain theoretical knowledge.

When shooting the scenery, the polarizing mirror is very useful, especially when the sky is dark, it can make the color of the blue sky more saturated, while highlighting the clouds in the sky.However, the material must be reversed. Do not use polarizing mirrors too much, such as the reflection of the leaves and grass is also polarizing light. These reflectives are conducive to expressing details and layers. If these Lights are eliminated, the screen will be overwhelmed and there is no level.

The greater use of polarizing mirrors is to eliminate reflection, such as the reflection of the water surface and glass window.In this way, you can shoot more details, such as things in the window, or rocks and water plants in the water.And polarizing mirrors can reduce the amount of light in the lens, slow down the shutter speed, and play the effect of similar to the medium -density mirror.

Polaries are divided into two types: linear polarizing mirror (LPL) and circular polarizing mirror (CPL). The former is mainly used for old -fashioned manual cameras because it interferes with automatic exposure and camera light metering system.Most of the polarizing mirrors on the market are CPL. When buying, choose a ultra -thin Polarized mirror when using a wide -angle lens to shoot according to your own lens caliber, so as not to occur to avoid dark corners.

When shooting the scenery, learning and using a circular polarizing mirror will have an immediate effect, making your photos refreshing.

How to use Polarized mirror

1. The brightness of the dark sky

By rotating the lens, the many partial vibrations in the roof reflection can weaken the intensity of light in the sky, darke the sky, and increase the contrast between the blue sky and the white clouds, making the sky blue and the clouds whiter.It should be noted that the CPL mirror does not affect the color of the light.

2. Eliminate the reflection on the surface of water, glass and metal

When the light is projected to the plane objects, such as water, glass, paint furniture, etc., it usually produces a strong SLR reflex light, which will become a high light point in the photography screen.This highlight point will affect the shooting effect. At this time, if you use the CPL mirror for shooting, you can improve the picture quality of the photo and improve the clarity of the picture.With the CPL, the previous reflective water surface does not affect your shooting. You can take more clearly to the fish in the water; add CPL, the previous reflective glass window will not affect your shooting. You can shoot more clearly.The exhibits furnished in the glass window; add CPL, the previous reflective window will not affect your shooting. You can shoot the charming scenery outside the car window from the car.

3. Replacement neutral gray filter

CPL mirrors can reduce exposure 1-2 gears, which can replace the role of medium gray mirror.Under certain needs, 1 or 2nd exposure can be reduced.

Many photography enthusiasts know that using polarizers can make the blue sky blue and eliminate reflection on the surface of glass, water and metal, but in fact, the polarizing mirror has more effects.When shooting in cloudy weather, polarizers also have obvious effects.Although it does not turn the gray sky at this time, it can make the color stronger by removing the reflection on the surface.For example, shooting the leaves of plants, the surface of the glass and the slippery stones of the plant in cloudy weather will reflect some light from the gray sky.These reflection obviously fade the color.Add a Polarized mirror in front of the camera. Slowly turning the front lens, you will find that the leaves of the plant have thickened the leaf surface.installation and non -mirroring are shot the same scene, you will find a very obvious difference in the photos you shoot.In cloudy weather, the effect of increased color saturation through polarizing mirrors is as obvious as eliminating reflection.

When using a polarizer, just set it in front of your lens, watch the front lens of the Polarized mirror at the same time through the viewfinder, until the result of satisfactory, then you can press the shutter to focus and adjust the layout of the screen.Press the shutter.

However, some photographers who use polarized mirrors for the first time said that they could not observe any changes when rotating polarizers. This is because the polarization mirror has the best effect when the light is in the direction of the light and the axis of the lens is 90 degrees.If you shoot against the sun, or face the light source (sunset), the Polarized mirror will not have any effect.But if the light comes from your left or right, or directly from the top of the head (the sunlight at noon, cloudy weather), the Polarized mirror will magically eliminate the reflex, the dark blue sky and improve the color saturation.

Is it good to wear polarizing mirrors for fishing?

Polarized glasses are generally wearing in summer. summer sunlight is spicy. Wearing polarizers can help reduce the stimulation of the sun and sunlight to our eyes.

Of course, don't rely on polarizing mirrors to protect the glasses. Try to choose the position of the backlight or side backlight. The fishing time is easy to arrange before 10 am, after 4 o'clock in the afternoon, or at night.Avoid direct sunlight, which is good for the protection of the eyes.If you fish all over the weather, you must wear a hat when you go out, and then with a pair of Sunglasses, the hat is better to choose a long sun hat with a long hat tongue, and it is advisable to use white; Sunglasses should be green, UVA, UVB in UVA, UVA, UVB in ultraviolet raysThe ingredients are harmful to the eye, so you should choose a Sunglasses with good texture.When buying Sunglasses, pay attention to its optical flux and filtering UVA, UVB and other coefficient indicators.In addition, wearing glasses is also good for preventing the eyes from air dust and flying insects.

What are the effects of fishing Polarized glasses

1,Suitable for summer use.In summer, the sunlight is relatively spicy. Under the shining of the water waves, the eyes will often be unable to open. At this time, if you wear fishing Polarized glasses, you can avoid the occurrence of the eyes of the eyes.

2,Protect the eyes.Whenever you fish under the sun, the ultraviolet rays in the sun, etc. can cause certain damage to the eyes. fishing Polarized glasses can effectively avoid these light. Some studies have pointed out that fishing Polarized glasses can block 90 % of ultraviolet rays and avoid the eyes of the eyes.harm.

3,Observe to observe floats.When the wind is windy, it will affect the water waves, and it will also show people a certain pressure on the float. Polarized glasses clamp a special filter film in the lens to filter out the dazzling strong light of reflection.After wearing it, it can facilitate people to observe the float and avoid missing any fishing information.

How to choose a fishing Polarized mirror -specific glasses

1. Consider the color of the lens

Amber and brown lenses are the most suitable.In the autumn and winter seasons, the light is relatively weak. In the case of cloudy, rainy, snowy, snowy, cloudy, heavy fog, etc., the visibility of the weather is low.Clear; the light in spring and summer is relatively strong. When the sun is fierce, brown lenses can block the light to prevent the eyes from being damaged.

The current polarizer generally has gray -green lenses, bronze (reddish) color lenses, and yellow lenses.The light transmission rate is gradually increasing.The gray -green lens is suitable for use when the light is the strongest, such as noon and summer.

Bronze lenses are suitable for use when cloudy or light is not very strong. At the same time, bronze lenses have a clear effect. It is particularly sensitive to the color of the red system. It is also a lens color that has gradually begun to become popular in recent years.And deep bronze, the clarity of light bronze is better.

The yellow lens is suitable for the morning, evening, rainy days, and night use, which mainly plays a role in glory. At the same time, it can avoid the damage caused by the blue light during the night fishing.

In addition, there is a yellow polarizer in the yellow film, which means that the light increases and the effect of polarizing. This kind of lens is particularly suitable for use in the morning, evening, and cloudy days.The effect is very good, but it is not suitable for night use, which will appear darker.

2. Suitable for yourself

Before selecting fishing Polarized glasses, you should try to wear it, let your eyes feel the effects brought by different lenses, and then make choices.

In the hot summer fishing, there is a good polarizing mirror that can protect our eyes well. It can also be seen more clearly the signal of the water buoy in the water, especially fishing in the dense gaps of the aquatic plants. You can see more clearly.Location.Polarized lenses are made based on the polarization principle of light. It has a unique function of eliminating glare. It has special effects on the fishermen, which can improve vision and add fishing fun.
