1. What is the principle of color change Cycling glasses

Trimous glasses can change the color of the lens according to the strength of the external light, thereby protecting the eyes from strong light stimulation. Therefore, many friends choose to wear colorful glasses when riding, but many friends do not know the principle of color change Cycling glasses.The working principle is simple:

1. When making color -changing Cycling glasses, the light color material is added to the glass raw material. The lens contains silver (silver chloride, silver bromide) microcrystalline.Electronics, the electrons are captured by silver ions and reacts: colorless silver is decomposed into opaque silver atoms and transparent halogen atoms. The silver atom absorb light to reduce the light transmission rate of the lens, so the color of the glasses changes.

2. Because the halogen in the color changing lens is not lost, the reversible reaction can occur. After the activation of the light disappears, the silver and the halogen are reused to restore the lens to the original transparent colorless or light -colored state.

riding is often outdoors and needs to be stimulated by the sun. Therefore, it is better to wear a pair of discolored Cycling glasses. However, some friends are worried that the color changing Cycling glasses will be harmful to the eyes.Intersection

2. Is riding colorful glasses harmful to the eyes?

The light transmission rate of color -changing Cycling glasses is relatively low. Although it can absorb most of the ultraviolet, infrared rays, and various harmful glare, due to the halogen chemical components contained in the lens, the light transmission rate of the lens is relatively poor. If it is used for a long time, it is used for a long time.It may cause visual fatigue and not suitable for long -term cycling.However, with the advancement of manufacturing technology, the discoloration rate and fading rate of color -changing lenses have greatly improved, and high -quality color -changing Cycling glasses almost have no harm.

In addition, it should be noted that there are some inferior color -changing Cycling glasses unevenly discolored, either slow color change, fast fading, or fast discoloration and slow fading, and some even do not change color at all. This Riding glasses can not be worn for a long time.For effective eye protection, you should pay attention to buying two lenses when you buy.

How to match myopia Sunglasses

Persons with myopia need to consider the refractiveness of the glasses.Although it is easy to wear a layer of Sunglasses on Myopia glasses, the lens is heavier, and the double -layer lens looks cumbersome, and it is easy to shift or fall off during strenuous exercise.With a pair of Sunglasses with myopia, the advantage is relatively light, beautiful, and easy to fix.

Patients with low or moderate myopia can wear general, no refractive Sunglasses without affecting security.For patients with high myopia (higher than 600 degrees), they still need to wear refractive Sunglasses to be safe.Of course, no one can wear in inferior Sunglasses, because this Sunglasses are damaged to the eyes.

Sunglasses that are not suitable for close -up mirrors

1. Excessive circle shape affects visual effects

In order to achieve beauty, conventional Sunglasses are generally large and can cover the face in a large area.Generally, this large circle of lens is compared with the long face and long face of European and American high noses, and there are many uncoordinated features that are generally rounded with Asian faces.At the same time, the large -circle lens is relatively large, and the matching lens shape of the matched dyeing lens is corresponding and thick. Even if it is treated to a certain degree of beauty, there will be less beautiful edge thinning platforms.It is very different from consumers' initial aesthetics.

2. The best effect cannot be restored in the lens

Whether it is internationally or domestic first and second -tier brands, it can be described as good intentions in the design of the lens. The membrane layer, color matching and function are matched with the brand value, and it is mostly visually comfortable.The lens experience and good texture and good styles are favored by consumers.However, after such lenses are replaced, it is difficult to obtain lenses of the same quality and color sense, and the price of polarizing lenses today is relatively high, mostly dyeing, and the texture and performance of dyeing lenses cannot match polarizers.

3. Insufficient gravity of the circle is not enough

Pursuit of light and light has always been the design purpose of glasses.This is even more so Sunglasses, so it is fully considered "burden reduction" in each link during design, and the circle is one of the objects of the extreme chemical.As a brand of Sunglasses that has been formed, the slender circle wire design is in line with ergonomics and wearing habits.But please remember: they are tailor -made for the pair of light lenses on the frame. If they want to replace the flat lenses with a degree of lens, the original bearing grace of the original circle will be.Stretching, this is like a piece of S -size clothes. The object suddenly changed from 160 to 170. It is common for cracking and falling off.

4. The slot type and the lens cannot be perfectly stuck

The slot type of conventional Sunglasses is a U -groove, which is no problem for the flat lenses, and the stability and firmness are very good.However, when the lens is replaced with a degree, "rejection" will appear between the U groove and the lens.The cold shrinkage appeared. The original summer was just right. In autumn and winter, the lens suddenly fell off.

How to choose Sunglasses in myopia

1. About the depth of color

The filtering of Sunglasses with too light color affects vision with too much color.Many users think that tea, gray, and dark green are more moderate.Their filtering effect is better, and the scenes seen after wearing a mirror will only become darker without obvious color difference.

2. Examination of appearance

In addition to the lenses, there must be no scratches, impurities, bubbles, and stripes, women who love beauty must pay attention to whether there are UVA, UVB, and CE logos on the mirror or tag. Only these signs can play a role in anti -ultraviolet rays.

3. It is comfortable to wear

When buying Sunglasses, do not follow the trend blindly, but also choose the size, curvature, etc. according to your face shape.In addition, when trying to wear it, it depends on whether there is a sense of dizziness. The dialysis is not high. It is best to have a polarizing function.

Mooth classification of Sunglasses lenses

1. glass lens

The glass lenses are often exposed to it. The most prominent advantage of glass lenses is that its optical properties are very stable. This is the usual advantage of glass lenses. It is the same on frame glasses.Affected by the pressure of the framework.The disadvantage of glass lenses is that it is easy to break, and it is easy to cause damage to the eyes.At present, the newly developed enhanced glass lenses are more prominent than ordinary glass lenses, and they are also considered a safe lens.

2. Polarized lens

This is a lens used on polarized Sunglasses. The polarization principle of light is used. In the future, the glare obstruction of the parties will be separated from the lens to make the sight clearer and safer when driving.In 1937, Dr. Edwinland in the United States invented this lens and was widely used in polarizing Sunglasses, and he also created his own Pokmon company.

3, color change lens

Also known as sensitive lens, due to the change of light, the color of the lens changes accordingly, so that the eyes can adapt to different environments. Under the strong light, the color of the color changing lens will deepen.EssenceThis kind of lens has been used in myopia Sunglasses. This kind of Sunglasses in the form of color -changing lenses are also considered to be the most convenient and most beautiful myopia Sunglasses, which is more popular than clamping.

4. Plastic lenses

This is the material that many Sunglasses brands like very much. Light and not fragmented are its most obvious features. The functions of non -processed plastic lenses are significantly better than glass lenses.EssenceThe disadvantage of plastic lenses is that its wear resistance is easier to scratch.

There are three main types of plastic lenses, namely resin lenses, PC lenses, and acrylic lenses.

5. Resin material Sunglasses lens

Friends who often wear glasses must have heard of resin lenses, but what are the resin lenses?Resin (CR-39) is actually a chemical substance of the phenolic structure.
