In current market of eyewear, the eyewear supplier and distributing enterprises are quite many; sunglasses, acetate eyewear, metal eyewear , optical frames styles are diverse, quality levels various. It’s always difficult for customers to choose. So how to choose a good quality eyewear? Hereby, As a top quality lamination acetate eyewear supplier we make a brief introduction as follows:
Aoker
First, look at the surface. Try to choose the eyewear for which the lenses surface is clear, shiny, of no scratches, bumps, corrosion and other problems.

Second, look at the marks. Frames (metal frames and acetate frames) from regular eyewear factories, except printing the number, size, dimensions, but also need printing the trademarks (Pinyin or English). And the printing is clear, unlike some no-name’s shoddy products.

Third, look at the structure. Pull the frames’ two temples; put the frames on the eyewear or tables flatly. The frames and temples should be tilted 10 to 12 degrees angle; two rims shall be the same large, the temples shall be of the same length, the nose pads shall be of the same height, the temples shall touch on the same surface.
Fourth, look at the joint point; check whether the hinges between frames and temples fit or not. Metal frames have a lot of welding points. We should check whether these welding points firm and clean.

Fifth, testing frame’s material. When choosing metal frames, using hands to bend the rings or temples a little, and test the degree of hardness. Some are made of copper, stainless steel and iron. Top grade eyewear are made of nickel alloy which has high strength and flexibility, can be worn long time without distortion. When choosing fiber frame and plastic frame( injection sunglasses and acetate sunglasses), should select flexible material.

Sunglasses and Optical frame, although they are two different kinds of eyewear, but the identifying way are almost the same.

How to identify genuine and fake designer sunglasses

Aoker eyewear (2)Summer is coming; a piece of good sunglasses can not only play the role of eye protection, but also reflect a person’s taste. However, in the high-profit sunglasses retail industry, products quality varies greatly. The similar sunglasses’ prices difference can be tens or even hundreds of dollars. As ordinary consumers, how to choose it?

As a professional eyewear manufacturer, we suggest consumers to purchase the sunglasses from a regular or a certain well-known enterprise’ products. Because counterfeit goods or shoddy inspection products are often not qualified, quality can not be guaranteed. Such sunglasses can not protect our eyes; long-term wearing will also cause some damages to our eyes. So, how should we identify the authenticity of sunglasses and get the products we really need? Here are just a few simple methods.

The first way is to check the products codes. Actually it is very simple, unlike fashionable dresses and bags; each pair of sunglasses has its own model codes and color codes which are specifically set by the manufacturer. These codes can be founded out in their official website. If one product has no model code, or models and styles don’t match which are sourced from authoritative website, it’s naturally counterfeit goods.
The second way is to check the certificate accompanied. Take an example, Italy has many world famous brands of glasses, also has the world’s most renowned eyewear manufacturers.
Aoker eyewear..

Safilo Group is the world’s largest acetate eyewear, metal eyewear, buffalo horn eyewear producer, based in Italy. Basically all the top brands of sunglasses are their products, such as Burberry, Dior, Gucci, Armani, Valentino, YSL etc. They strictly control the sales channels, not wholesale the products easily. In the United States, only those optical shops which get national industry certifications are eligible to purchase from Safilo. And there will be professional people who will supervise the shops and franchised stores, not allow a malicious competition of price reduction. Each pair of Safilo glasses will be accompanied with a certificate. If without Safilo certificate product, it must be faked. For example, regarding some imitation brands, styles can be realistic, but the certificate is not easy to be as a forgery.
In addition, we can identify the quality from sunglasses craftsmanship, look at the joint points of sunglasses components, the polishing, grinding etc. a pair of good sunglasses, the details treatment is also good. But for some imitated products, although the appearance is almost similar, some details are not treated well.

2) Lenses – when purchase sunglasses, must double check if the lenses are of high quality.
The simplest and easy-operated way is to put the lenses under lights, to see if there is steam, air bubbles or other residual defects on the surface.
This is not easy to be found during wearing, but it was decided to be of high quality sunglasses important index.
On this point, Ray-Ban sunglasses lenses did really a great job.
3) Experience, it is extremely important. The shops often let customers try on the sunglasses in their optical shops. But this actually will hide away a lot of “operational” encountered deficiencies. We recommend the customers try on sunglasses not only in the shops, but outdoors. And take it under strong sunshine, to observe the effect is good or not.
4) Color, sunglasses lenses colors on the market now tend to be more, except cool, individuality these factors, usually the blue, green and grey colors will not appear much color contrasts. Therefore, if you don’t wanna cause different views when wear and not wear sunglasses, you could consider above proposed colors.
5) Index, what’s index of sunglasses? It seems to have involved of some technical things, actually to identify if the sunglasses have ability to sufficiently block strong UV, the most basic is to see the sunglasses UV index is high enough? Generally speaking, high quality sunglasses UV index can be controlled between 95% to 97%.
Of course, the higher the better and apparently the prices are also proportional.
6) Price: frankly, the price is usually proportional to its brand popularity and lenses quality. Of course, a good brand also has more authority and more convincing lenses, eyeglass frame quality.
General sunglasses brand are Ray-ban, Gucci, Chanel etc…
Ray-ban sunglasses brand has a long history, also the quality is well guaranteed.

Different colors sunglasses lenses’ roles and effects

For sunglasses lenses, except the material used are different, such as acetate sunglasses, metal sunglasses, injection sunglasses. The colors are also different, as well as their roles and effects. Following is the introduction of different colors sunglasses lenses’ roles and effects:
IMG_8006
1, Grey lenses: A neutral color.
Grey lens can be balanced against any chromatographic absorption, so when watching, the scene will only be darkening, but will not have significant color difference. And will display real natural feeling.
2, Brown lenses: can filter a large number of blue rays; improve the visual contrast and clarity; in the foggy air pollution cases or worse weather, can block the lights reflected from smooth and shining surface, and the wearers can also see clearly the subtle parts. Brown lenses should be the best choice for drivers.
3, Green lenses: during the absorption of lights, at the same time, can maximize the green lights reached the eyes, so wearing green lenses can bring a cool and comfortable feeling. This color is suitable for eye fatigue people.
4, blue-grey lenses: neutral lenses, similar to grey lenses, but with darker color, higher absorption of visible light.
5, Mercury lenses: the lens surface uses high-density mirror coating.
Such lenses absorb more reflection of visible light, which used for sports glasses, suitable for outdoor sports people.
6, Yellow lenses: Strictly speaking, these lenses are not sunglasses lenses, because they almost do not reduce the visible lights. But in the foggy and dusk, yellow lenses can increase contrast and provide a more accurate vision, they are also known as night vision goggles.
Some young people wearing the yellow lenses sunglasses as a decorative usage.
7, Light blue, light pink and other lenses: decorative rather than practical.
8, Dark green lenses: absorb heat; bring cool feeling, but the light transmission and clarity are low. Suitable for wearing under sun, not while driving.
9, Blue Lenses: when having fun at the beach, blue color can filter out the lights reflected from blue sea and blue sky. During driving should avoid using blue lenses, because they will make us a confusion of traffic signal colors.

Different colors sunglasses’ roles and effects are not the same, so when consumers are choosing their own sunglasses, except choosing their favorite styles, also need to check if the color is suitable. Eyewear supplier warming wearing comfortable and healthy is the most important thing.

Basic Functions of Sunglasses

A pair of sunglasses looks very simple, i.e. two pieces of color plastic or glasses lenses into plastic or metal frames.
IMG_7968
In fact, the two pieces of lenses can cause quite many differences.
When you use sunglasses, these differences will have a great impact on you.
A pair of good sunglasses must have the following four functions:

To prevent ultraviolet radiation in sunlight
UV rays can damage the cornea and the retina; high-quality sunglasses can completely eliminate the UV radiation.
To prevent light exposure
When the eye receives too much light, it will naturally shrink the iris. Once the contraction of the iris to the limit state, then people need to squint. If the light is still too much, such as the snow reflected sunlight, will cause damages to the retina. High-quality sunglasses can filter out up to 97% of the lights into eyes to damages.
Pay high attention on details
To prevent glares
Some surfaces, such as water, can reflect a lot of lights, and this will disrupt the vision or hide objects. High-quality sunglasses can use a glare polarizer technology to eliminate such glares.
Eliminate specific characteristic frequency of light
Certain frequencies of light will blur vision, while other frequencies of light can enhance the contrast.

Choosing the right color for the sunglasses, making it to get better effects in certain circumstances. If the sunglasses do not provide UV protection, it will give you more exposure to ultraviolet irradiation. Cheap sunglasses filter out a portion of the light, causing your iris to open to receive more light. This also would allow more ultraviolet radiation to enter, increased ultraviolet radiation damage to the retina.

Thus, for a variety of sunglasses, there are many differences. For a particular use of the environment, to select a pair of suitable and high-quality sunglasses will provide you with maximum protections.

7 notes for choossing sunglasses

Spring and summer temperatures rise, jewelry and accessories will make women feel cumbersome. At this point, a pair of beautiful sunglasses with function of vision protect can become the best choice for fashion men to be cool. For sure Sunglasses have decorative functions, but its protection function is the most important one. Because if you can’t obstruct ultraviolet to some extent, it will cause damage to the eyes after long time, so when buying sunglasses, please pay special attentions to the following several points.
Aoker sunglasses
The first point is the observation of the lenses, to see if there are scratches, impurities, bubbles and stripe; to check the outer packaging of sunglasses, sunglasses should be marked with the formal name, color, diameter, quality levels, manufacturer and trademarks. The lenses or tags marked with anti-UVA, UVB and CE can ensure to block UV to some extent.

The second is to try on sunglasses to see if there is no dizziness, headache feeling. In current market there are some sunglasses marked with degrees for sale, but because of pupillary distance and other indicators vary, so if there is no professional guidance, the consumer would better not to choose these prescription sunglasses.

Third, handle sunglasses’ two angles onto a fluorescent lamp, let the mirror’s reflective surface scroll, if find specula reflection of sunlight lamp shadow appear wavy or twisted, it proves that the lens is not flat, this mirror will strain your eyes.

Fourth, to see if the lens is flat and clear. The sunglasses lenses material are mainly glass and resin. The best sunglasses lens is Polaroid. It can effectively filter out the reflected light and harmful ultraviolet radiation, and has features such as anti-crushing, guards against rubs.
Fifth, for sunglasses colors, except choosing as per the skin, face shape and wearing, but also according to access sites.

The sixth is to look at sunglasses lenses’ color depths. The color depths are divided into 15%、34%、50%、70%. Indoor and outdoor 15% can be worn; 34% for General outdoor environment; 50% for Sun and sea; 70itlectric welding and other special uses.

Seventh, to see if the sunglasses has a UV-resistant feature. Better to choose the lenses which has UV function. And the UV index should be between 96% and 98%.

Why acetate eyewear doesn’t in good shape?

1. The main cause of this issue is insufficient of heat acetate. It cause front and arms not fit the shape of a persons head. If insufficient of heat acetate, acetate eyewear, sunglasses will have some kinds of not good changes.

Acetate eyewear arms
–One change is that arms are too straight and do not have enough curve to fit the shape of a persons head.

Acetate eyewear front
–Other change that front too much curved inward and it makes arms very close to each other.
Too close between arms will causes the acetate eyewear very uncomfortable to wear for customer

–Another change is that front too straight and it makes arms very far away each other.
It causes the frame very uncomfortable to wear for customer

Aoker manufactory has detailed rules and addition steps for heating acetate.
The other manufactory doesn’t have time enough and addition steps for heating acetate compared with Aoker.

2. Maintain shape problem (it involves fix front, arms, arm opening size, screws tightness etc…)
Usually Maintain shape is processed by very skilled stuff. It is to make acetate eyewear in good shape and comfortable wear. But if insufficient of heat acetate, even if the stuff maintain shape perfectly, after a few time, the acetate eyewear must be loose shape quickly.

BTW, the acetate eyewear in folding condition in retail packing for a long time, it can cause right arm less curved than left arm. This is due to the gravity of acetate eyewear makes right arm less curved. So when maintain arms, right arm need curved a little bit more than left arms, in this way, the gravity of acetate eyewear will make the equal curve of arms. Aoker manufactory realized this issue.
