one,Polarized lensCharacteristic

The polarized lens is compressed by multi -layer thin resin materials, which is relatively lightweight.Each layer has different effects.The middle layer is a polarized layer, and its principle seems to be a shutter, which can filter out of the strange reflection light.The second and third layers can filter 99.9%of the harmful ultraviolet rays and reduce the strength of the light. The function is no different from ordinary Sunglasses.The fourth and fifth layers of polarized lenses are the anti -impact layer, making the lens not easy to break; the sixth and seventh layers are strengthened, making the lens difficult to wear.Polarized mirrors can filter out harmful light to protect the eyes.

Although polarizing lenses can filter out many irregular light interference and avoid dazzling, dazzling, etc., if the arc bend of the lens itself cannot be in the state of optical optical standard refractive state, the polarizing effect will be weakened, affecting the authenticity of the image, and durablePoor sex.

The general polarizing Sunglasses on the market are made of fibrous clip polarizing membrane.It is different from the optical glass polarized Sunglasses. Because of its soft texture and unstable arc curvature, after the lens assembly is upper frame, it is difficult for the lens to meet the optical refractive standard, and the image is loose and deformed.Due to the unstable arc curvature, the lens deforms, resulting in the clearness of the light transmittance image, the image distortion, and the effect of normal lighting.And the surface is easy to scratch, wear, and imperative.

Second, the role of polarizing mirror

The effect of polarizing mirror is to effectively eliminate and filter the scattered light in the beam.Make the light into the eye visual image in the transmittance of the light, making the field of view clear and natural.Like the principle of shutters, the light is adjusted to the same direction and enter the room, naturally makes the scenery look soft and not dazzling.Specific to daily life:

1. When driving, it will no longer bother the many reflection from the sun and the vehicles in front.

2. When fishing, the water wave shines under the sun, but you will not feel uncomfortable at all, but feel comfortable and disappear.

3. When skiing, you don't have to worry about reflective and ultraviolet rays, you can skate.

4. When it rains, the road traffic signs with rainwater flow are clearly presented in front of you.

5. During vacation, let you enjoy the sun, beach and leisure time.

Three, DaiPolarized glassesWhat are the benefits

The ideal polarized Sunglasses should have the following conditions:

1. It must be able to filter more than 99%of the ultraviolet rays in the sun, and the filtering performance meets the requirements of international standards.

2. Effectively block the function of strong light.

3. The lens has a standard optical arc design, forming an optical shaft to produce video.

4. The eye frame is firm, the frame material is excellent, and the optical function is designed. It feels comfortable and safe after wearing.

Polarized Sunglasses are a combination of substances. Generally, the two layers are combined with seven layers.In the middle, the middle layer is the polarization layer.The polarized layer is effective, but it is not wear -resistant and is easy to scratch.

The polarizer can reflect the random reflex light, glare, and irregular reflex light resistance in natural light. The inside of the polarizer has 300,000 linear lines that can not be seen in each 1 Square centimeter.direction.

Compared with ordinary glass Sunglasses, polarized Sunglasses do not affect vision and will not cause color difference.At the same time, it can effectively avoid the damage of ultraviolet rays to the eyes.

1. What harm can the eyes be suffered during the cycling movement

riding is a good movement, but because it is exercising in the Outdoor sun, if you do not pay attention to protection, not only do you not achieve good exercise effects, but it is easy to hurt yourself, especially the protection of the eyes in the cycling motion.It is very important.Eye damage that may suffer during cycling is:

1. Sunshine

Direct light of strong light will make the eyes unable to open and affect the safety of the cycling; the glare generated by the reflection of the sunlight will also affect the clarity of the sight; the ultraviolet rays and blue light in the sun will cause direct damage to the macular part of the eyes.

2. Wind sand

The wind blowing into the eyes when riding is very strong, especially when the ride speed is faster. In addition to making the eyes difficult to keep it open, it will also make tears quickly and volatilize.Eye fatigue; in the long run, the corneal epidermis of the human body will cause damage, and it will tingle even if it is not cycling.

3, foreign body

During the cycling process, the flying sand, mosquito, rainwater, etc. are foreign objects that are easily invaded into the eyes. Sometimes, even if we put on ride glasses, block the directly impact, sweat, rainwater and other liquids may still flow into the eyes with impurities.Cause stimulation.The human body has no keratin, which is more sensitive than the Skin, and it is easy to induce allergic conjunctivitis. Dry, itching, severe tingling, and tears have more than any symptoms.

It can be seen that if the cycling movement does not pay attention to protection, the danger is ubiquitous, especially in the long -distance ride, so we should pay attention to wearing ride glasses. So what is the use of Cycling glasses?

2. What are the effects of Riding glasses

Riding glasses and riding helmets and magic turban are also called three -piece set of head protection. They are mainly protecting the head. Riding glasses are mainly used to protect the eyes. Its role is:

1. Anti -collision

The toughness of the ride of the glasses is quite good, which can prevent the hitting the eyeballs of the sand and the flyworm.The front car is pressed on the pavement with gravel, which often leads to the flesh of gravel, especially the highway vehicle with high tire pressure and high hardecling hardness.The anti -collision function of the glasses is to prevent this accidental damage.

2. UV prevention

cycling is outdoors. If you don't wear Cycling glasses, you can't open your eyes when the sun is big. This will affect the observation of the road conditions ahead and may cause a series of unsafe factors.With Riding glasses, it can not only shade and sunscreen, but also has anti -ultraviolet function, especially suitable for summer cycling and high altitude ride.

3. Wind -proof

If you do nt wear ride glasses for a long time, your eyes will become very dry, or even red, and very uncomfortable. This is mainly caused by the fast riding speed and the wind blows into the eyes.When high -speed cycling, prevent wind from blowing directly into the eyeball, reduce the impact of the airflow on the eyes, and prevent the wind from invading the eyes in the wind.

The above is the role of Riding glasses. If you want to ride, it is necessary to wear a ride glasses.

Is basketball goggles useful?

Facing some basketball enthusiasts, it is often caused by Dai Optical glasses to play basketball.basketball goggles can prevent the eyes from being impacted or pierced during exercise, and can also be equipped with a degree of basketball glasses for myopia.basketball frames are generally different from ordinary glasses.For example, materials must have a super -strong impact function, and it is best to use PC and polypropropylite, etc. with good toughness; the color should not be too bright, otherwise it will affect the vision, especially in the exercise with higher reaction requirements.It is easy to cause mischief; the other most important is safety. The frame must have functions such as corrosion resistance, anti -falls, difficulty aging, and parts of parts.

How to match basketball goggles

1. Number of decreases: decreased by 25 degrees below 500 degrees, and decreased by 50 degrees greater than 500 degrees.However, there are some high degrees that need to be reduced by more than 100 degrees to adapt, but some people do not need to reduce it. This varies from person to person.

2. The pupil distance is suitable: the frame and the eyes should be controlled within 10mm. For example, your pupil distance is 65mm, so it is best to choose a mirror-frame pupil distance of 62-72mm.

3. Frame selection: Be sure to pay attention to the degree of curve.

4. Anti -fog problem: It is almost impossible to buy an anti -fog agent, because myopia lenses are almost impossible.If there is no anti -fog agent, when you run in winter, there is a white, very sad.

5. After -sales problems: Although the glasses are not expensive, but there are problems, there is still a special after -sales after -sales.
