How to distinguish the quality of Sunglasses

Judging the advantages and disadvantages of Sunglasses can be examined from both quality and aesthetics.Aesthetic has personal factors, and quality is standard.The quality of Sunglasses mainly refers to the quality of the lens.At present, the world's general standards are the standards of the US Food and medicine and Health Inspection (F D A) standard.

1. According to the F D A standard, while the lens guarantees the light transmission rate, it is necessary to filter more than 90 % of the ultraviolet rays in the sun, and the lens should be labeled "UV-100protct10n"."UV-400protct10n" tag, so it is very important to check the UV tag on the lens.

2. The lens must not have the "degree" of optical lenses.Generally, if the refractiveness exceeds 15 %, it will feel dizzy when wearing.

3. The lens must have a high strength and pass the impact test.Generally speaking, the strength of plastic film (propionic acid or acetate), resin tablets, and glass tablets from small to large.

How to distinguish the quality of Sunglasses lens quality

1,Material of the lens

glass lens: wear resistance, but relatively speaking, its weight is heavier than other materials, and it is also easy to break.

Popular resin lens: This kind of lens is lighter than glass lenses, impact resistance, and is not easy to break, but the hardness is low, so it is easy to get hair and it is easier to have scratches.

2. The refractive index of the lens

The higher the refractive index, the thinner the lens, the higher the price.Such as the optical characteristics of the lens:SunglassesIt is a flat -light mirror, which cannot be littering, and should not have optical defects that affect vision.

The simple method of identification is to place the Sunglasses in front of the eyes and observe the distant targets through the lens, such as window frames or door frames, and then move the glasses up, down, back and forth, the target should not be swinged and wavy deformation.

3. The color of the lens

Sunglasses are divided into dark and light colors without color distortion.The choice of the color shades of the lens should be depends on the places of the required activity. Selecting different colors for different light sources and different use occasions, the color of the lens will affect the Shading effect.To enable Sunglasses to effectively block the strong light in summer, dark Sunglasses are needed, but if you wear a bike or drive, you should not choose a lens with darker colors.In addition, when Sunglasses are used for daily driving, they also need to have the ability to identify different color signal Lights.

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 is polarizing mirror

The polarizing mirror is a lens manufactured based on the polarization principle of the light. It is used to eliminate and filter the scattered light in the beam, so that the light can put the eye visual image in the light transmittance of the right track, making the field of view clear and natural.Mostly used for Sunglasses and camera lenses.

Second, the principle of polarizing mirror

The role of polarizing mirror is to filter reflective light and increase imaging contrast.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.

Polarized mirror 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 polarizer.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.

3. Polarized Sunglasses buying skills

Sun glasses are not only used in summer, but they must be used all year round.Wear it on a sunny day, and it should be worn on a cloudy day.Do nt think that the sun is not strong and the weather is not hot, so it s light -hearted, and unknowingly illuminated more harmful ultraviolet rays.

1. First consider quality

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.You can choose to have polarized Sunglasses with the best blocking ultraviolet logo with the "UV400"; inferior polarized Sunglasses, such as dark Sunglasses. As the light of the human eye darkens, the pupils of the human eye will become larger, and the eyes of human eyes will become larger.increase, increase damage to the eyes.

2. The truth and nature of the vision

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.

3. Will there be discomfort for a long time?

Genuine polarized Sunglasses must be comfortable to wear; inferior lenses have no technical and functional at all when manufacturing, and the lens materials are also very inferior. After wearing it, feel uncomfortable, dizziness, headache, dry eyes, tingling, etc. should be stopped immediately.Essence

4. Look at the protection function of the frame

Most polarized motion Sunglasses frames are designed with veneer arcs, which can effectively prevent wind and foreign bodies from stimulating the eyes in outdoor sports.In addition, the hard level of polarizing lens and the flexibility of the frame of the frame consider whether it will hurt the human body.

Suitable for glasses with a slightly thicker frame, cold lens color, and darker colors, with the visual effect of "tightening" face.Too gorgeous yellow, red lens or frame lines with slender and soft Sunglasses will set off the face larger.

2. Small face shape

It is suitable for wearing fine frames or frameless glasses to choose elegant blue, purple, light brown and other lens colors, which will have unexpected effects.

3. Long face shape

You should choose a flat or curved mirror, a slightly thick mirror foot to weaken the slenderness of the long face.The slender face is generally skinny. Choosing a pink or wine -red lens with a more feminine flavor can increase the brightness of the face.

4, Square face

It is advisable to choose a Sunglasses with a narrow width and a Smooth four corners of the frame. Too large and too large mirror frames will only make the face look more Square. The color of the lens is better brown.

5, apricot face

Suitable for the lens to choose the lighter color, the fine metal frame or the frameless glasses, to weaken the weight above the face, so as not to make the upper face that was originally widened.

6, inverted triangle

Eastern glasses with thicker frames, darker colors, and slightly width of horizontal width should be used to adjust the proportion of up and down, which visually coordinated.

3. Recommendation of Toad mirror models of different faces

1. BL8118 and 8116, 8100:These styles are particularly suitable for Square faces, which can modify the face shape well.
