How to choose the frame?(1)


First I should tell you that: I have only one answer for your question about what the kind of glasses is fit for your face .
Look at the mirror, look at the mirror, look at the mirror.
You will know whether your glasses is fit for your face or not after a careful observation.

So let's talk about the two things of wearing comfort and how to identify the frame quality.
A good frame should be made of a safe, reliable, skin-friendly material that is light, strong and not deformed. Secondly, for the wearer, it is also necessary to purchase from the perspective of the practicality of the frame.
When the frame is selected according to the visual condition and use, the glasses are used for long-term wear, and other conditions can be appropriately relaxed to select a lightweight shelf to reduce the wearing fatigue.
If the glasses are only worn when the eyes are read and watched, and the eyes are worn, the frames can be selected according to individual needs.
Half-frame and frameless frames should not be used for high myopia. Because the thickness of the lens is thicker and the frameless frame is not only unsightly but also easy to damage.
If the astigmatism is higher, the frameless frame should not be used, because the lens with the frameless frame will have the problem of displacement of the astigmatic axis after a long time of use, which will cause the object to be deformed.
Specific needs: If the purpose of the glasses is largely for the matching of the image and the specific attendance. At the same time, in the case that the vision condition is not limited to the frame, you can choose according to your specific needs.

What kind of frame is a good frame, from three details can basically determine the quality of a frame.
1, on the color - look at the depth of the color.
Put the glasses flat in front of the eyes, and observe the color of the temples under the same light intensity. Sometimes the color of the left and right temples is asymmetrical due to processing errors.

2, the processing - see the details.
The craft is the quality assurance of the frame, and the craftsmanship of a pair of frames is often reflected in the details.
(1) Whether the two temples are flat.
Place the frame flat on the table and see if the contact points are floating. If there is a situation where one side is high and the other side is low, it is necessary to require the professional to adjust the temples to achieve the effect of balancing the left and right balance.
(2) Pay attention to the vicinity of the welding point of the metal frame to see if there is any crack.
Since the thermal effect during welding changes the stress structure of the material, or the virtual welding, material fatigue, etc., it is prone to fracture when subjected to force.
(3) The stipules of the frame should pay attention to whether the two sides are symmetrical and whether the fixation is safe.
(4) Open and close the temples and feel the elasticity.
It is generally believed that the tighter the better the view is wrong, which means that the lubrication of the screw is not enough, so it is easy to cause the temple damage. But the temples is too loose, which is that the screw may not be tightened. It is optimal that the tightness is moderate.

What is more important ? Lens or Frames ?

When I first started a business a few years ago, I would go to the office buildings to push and promote the glasses frame that we designed ourselves. In the process, I often encounter some very "smart" customers. No matter how I sell frames to them, they will block them back in one sentence: Don't sell the frames! The frame doesn't matter, so I only need the best lens! I have nothing to debate with him when I encounter such a "smart customer." In their eyes, the lens are the most important, and the quality of frames is nothing to care about. But in fact, the phrase goes that "good horse with a good saddle", which can be applied to choose your glasses. A good frame with a pair of ordinary lenses will not affect the optical performance of the lens and will not cause any harm to our eyes. However, if it is a good lens, it is not mounted on an accurate frame, not only can not play its normal optical performance, but also may cause damage to our visi...
