1. Does the myopia swimming mirror hurt your eyes?

Generally speaking, if it is a qualified myopia goggles, it usually does not hurt the eyes.Because the effect of myopia wearing myopia goggles is basically the same with the time when wearing myopia, as long as you can see the water surface when swimming, you usually do not have a bad impact on swimming enthusiasts.If myopia goggles are poor or the number of myopia goggles does not meet its actual degree, it usually causes certain damage to our eyes.

2. How to choose myopia swimming moster

(1) Clear and broad visual experience

1. Selection

If the degree of the wrong myopia swimming moster, dizziness and vague vision will appear, but the degree of goggles that should be selected is not the actual degree of myopia. Because the refractive index of water is higher than that of air, the degree must be compared to the frame glasses worn by the usual frame glasses wearing it.Low.But how much should I choose?The standard provided by ophthalmology experts is:

The degree of Swimming goggles is equal to the number of myopia plus half of the number of astigmatism, and then minus 50 degrees to 100 degrees.For example, if your myopia is 400 degrees and astigmatism is 0 degrees, then the myopia goggles suitable for you are 300 degrees to 350 degrees.In addition, if the degree of myopia is not consistent, the one with a lower degree is prevailing.

2. Look at the performance of preventing fog

The myopia goggles with good anti -fog properties have strong water vapor absorption capacity. Its anti -fog coating contains hydrophilic chemical components, can absorb more water vapor, and use high -tech to prevent anti -fog layers from preventing anti -fog layers from preventing anti -fog layers.Fall off.

3. Look at the field of vision

Generally, the visual field of large size Swimming goggles is wider, but when choosing, it is necessary to consider the degree of fit with the face. This is the second criterion for choosing the goggles: it is comfortable to wear.

(2) Comfortable comfort that is just right

How to judge this myopia goggles for a long time is really appropriate?There is a small trick when trying to wear. Without a mirror strap, the swimming mirror is attached to the face. If you feel a slight adsorption, it means that the Swimming goggles and faces are good.Whether it is perfectly fit, is the length of the nasal bridge just right?

Coupled with the mirror tape to try, determine whether the tightness of the mirror band makes people comfortable, whether the softness of the loop of the eye socket is just right. If it is too hard, it will cause the pain of the eye Bone.The risk of increased intraocular pressure.

(3) Safe and harmless material

The Skin of the eye is very delicate. The mirror zone and the pads are the most frequent parts of the eye Skin, so the material must be safe and harmless.Most of the professional Swimming goggles of well -known brands attach great importance to this point. It uses safe, environmentally friendly, non -toxic high -grade silicone. In order to allow people to leave the face without leaf marks on the face, it also uses liquid silicone.Essence

1. What are the requirements for Riding glasses lenses?

cycling is outdoor sports. The dazzling sunlight often leads to unavailable eyes, and often moves under strong light and is prone to eye diseases such as cataracts. Therefore, it is necessary to be equipped with Cycling glasses.In terms of aspect:

1. Material requirements

Riding glasses lens is made of special materials. It has good flexibility and resistance. It is not allowed to use glass as a lens. This is mainly to prevent Riding glasses from being injured when it encounters a foreign body collision or falling.Avoid scratching the eyes of the lens.

2. color requirements

Riding glasses are usually equipped with a variety of different colors of lenses. Different colors of lenses have their own functions and applicable scenes, such as dark lenses to block strong light and alleviate visual fatigue; yellow lenses are used for evening and night, and light increases light to increase light.Role; transparent lens is a windshield lens; colorful lenses are used in high -ultraviolet environment such as plateau and snow.You can replace it according to the riding scene when riding, so how to change the glasses lens?

2. How to change the lens on Riding glasses

A pair of Cycling glasses is usually equipped with a variety of lenses, which can be replaced according to different light; some myopia Cycling glasses can also replace the lenses. The following ways to teach you the replacement method of Riding glasses lenses:

1. The riding is mainly used to fix the lens on the mirror frame through the three fixed slots ends and the middle of the lens. When you want to change the lens, first pull out the one end of the cycling optical lenses out of the card slot and pull out the card slot out of the card slot first.Then take out the other end of the lens.

2. Then remove the lens from the small hook in the middle of the frame, so that the entire lens is completely removed, the lens removed is carefully placed, and then the new lens to be replaced is removed.

3. Pick up another lens, first put the lens card into the small hook in the middle of the glasses frame, and then stuck both ends of the lens into the card slot at both ends of the glasses rack.After the card is in the card, the lens will be stable on the frame.

4. After the three points of a lens are completely stuck into three fixed slots, the replacement of the ride glasses lens is completed.

1. How much is myopia swimming mirror?

The price difference between myopia swimming goggles is still relatively large. It can be bought for tens of yuan in cheaper, but this kind of myopia goggles are not recommended to buy. The waterproof and fog performance is not guaranteed. If you need to buy it, it is recommended to choose a well -known brand myopia goggles.And because of the reasons and degree of myopia swimming goggles, the price is different. The higher the degree, the more expensive the price. Generally, it is between 100-400 yuan.

2. Where can I sell myopia goggles

myopia swimming moster can be bought in online platforms, large supermarkets, sports goods stores, brand stores and other places.myopia goggles are relatively common swimming supplies. It is not difficult to buy on the market.If there are no large supermarkets or sports goods stores around you, you can buy it online.

What is polarized Sunglasses

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.
