Gunnar should be considered a household anti-Blu-ray glasses in Aunt Zhang. The first contact with this brand dates back to 2013. At the time when I saw the brand for the first time, my mind was impulsive and came up with four words - "for my wife," so I ordered a blue box MLG PHANTOM under the impulse of the official flagship store of Taobao Gunnar. And to the mother to buy a exactly the same, behind the map), his wife feels good, so he stunned the heart and gave himself Amoy a men's black box MLG PHANTOM. This Cypher is already the fourth deputy Gunnar spectacles. Get this pair of glasses and thanks to Gunnar's VIP assessment invitation (don't ask how I got an invitation)
The day before yesterday, the order was placed. At noon today, it was already in hand. Since it is a test, it may be worthwhile to take the box out as the beginning of the evaluation. Let's take a look at the opening photos of the goods.
Unopened look
Unpacking three-piece
After opening the bubble wrap, I was shocked. In addition to the glasses, I actually sent two things. Is it a brown wallet? Take a closer look at it. Needless to say, it should be glasses cloth. Regardless of them, first look at the Lord.

The back of the box
Side of the box 1
Side 2 of the box
Well, I can't stand it anymore. I must take it apart and take a look at the true colors of the mountains.
Out of the box
Destroyed the security tape and opened the heavy packaging, and finally saw the design of this so-called developer (actually, the code farmers, programmers) glasses
With Macbook
From the front, the glasses use agate black as the main color, as Gunnar's first glasses designed for developers, it is extremely heavy and simple, very traditional engineer taste, the bottom of the glasses are wrapped in stainless steel, but not careful Seeing it is invisible, this is the official so-called invisible frame. From the side, the temples are mainly made of stainless steel, and the back end is made of the same material as the frame. The inside of the stainless steel part of the temples is laser-engraved with the size of the glasses and the style of the glasses. On the outside is a big Gunnar. Because the material of the metal part looks very similar to the material of the Google glasses, it is full of sense of technology.
All in all, from the appearance of the glasses, this spectacles called Cypher contains both the black frame elements of the traditional engineer's glasses and the metal that embodies the sense of modern technology.
The word Cypher can be clearly seen on the left temple. Onyx means that the color of the eyeglass frame is agate black. In addition, you can see there are many small screws on the glasses, there are indeed old engineers.
The size of the glasses can be seen on the right temple leg. 54 ports 19-135 indicate the mirror width 54mm, nose bridge width 19mm, temple length 135mm
The nose clip seems to be fixed with screws. It looks a little punk.
Second, functional evaluationFor such a pair of glasses, the function of the horse is actually more important, but the author does not have a professional measurement tool on hand, so you can only use some special methods. Let's take a look at the basic Blu-ray filtering function.
We all know that white light is composed of three colors: red, green, and blue (as shown in the figure, thanks to Baidu Encyclopedia for illustration)
Then, after removing the blue from the white light, it is clear that the light will turn yellow, so this is why the vast majority of filtered blue glasses appear yellow. So we can easily conclude that Gunnar's glasses have a clear function of filtering blue light. But what about the filtering effect compared to MLG? We may wish to do a small experiment. Of course, because there is no professional equipment, just listen to the author's nonsense.
I don’t know if all the observers noticed that the blue light of the reflected light in the second chapter of the MLG was far weaker than the blue light reflected by the Cypher in the first one. Do not question whether it is an angle problem. This is what the author sees with his own eyes. I don't think it's a big difference. It may be a problem for the camera... So we can infer that Cypher's anti-blue performance is far better than MLG (because it reflects more blue light)
Third, accessories evaluationFinally talk about accessories, the evaluation of the accessories sent are:
1 glasses soft cover
This product is standard on Gunnar. Every time it will be brought, nothing to say, pass
2 folding glasses case
Although each time in the Gunnar Tmall flagship store will send glasses box (in Jingdong to buy do not think of this treatment), but this wonderful glasses box is indeed the first encounter, just opened the packaging thought Gunnar The line bought leather goods
This is the effect of this product after compression, like a wallet? Look like? Look like? Three important things to say. . . 
However, the goods are too big, obviously not designed for my Cypher, ah, glasses on the inside, this can not be described in language...
3 glasses cloth
This is also a novelty. I have never met this before buying at Gunnar. The material of the new glasses is similar to that of deerskin. It is reasonable to say that it is possible to wipe the lenses directly. This is not as good as the silk fabrics that were sent before. I know where I'm going
Fourth, personal experience Cypher as Gunnar's first glasses designed specifically for developers, from the design point of view is very successful, from the perspective of the previous evaluation, is also better than ordinary MLG's anti-Blu-ray glasses, but its biggest deficiency That's too heavy. Although Cypher's official label weighs 29g, my deep suspicion is that the label is wrong, because the MLG's weight must reach 249g, and this glasses is obviously heavier than MLG.
Secondly, to talk about the overall design of Gunnar glasses, for Gunnar, the frame itself is more curved. According to Gunnar official, this design can have moisturizing effect, but I personally do not feel it. . . This time for Cypher, perhaps because of the material, the frame design is not very curved, so if according to the official statement, the moisturizing effect may be reduced.
