From the material point of view, the currently popular glasses mainly include metal glasses, titanium glasses and acetate glasses. Each different material has its own different characteristics. So how to know the quality of the glasses?
How to know the quality when wearing glasses: check the frame welding process.
The welding process mainly occurs on metal glasses, titanium glasses or metal parts of acetate glasses. The identification of the frame welding process is a meticulous art, and a basic judgment can be made through the following three aspects.
1. Judge the quality of the frame by observing the uniformity of the welds. For an excellent welding process, the weld seam should be uniform without obvious ups and downs and discontinuities, which is a reflection of the welding master's skills.
2. Check whether there is any welding flash at the welding joint. Weld spatter is formed by the overflow of metal solution during the welding process. It is manifested in the appearance of strange bulges and uneven solder at the welding joint. Its presence not only affects the appearance of the frame, but may also affect the structural strength of the frame.
3. Check the welding firmness. The welding joints of a high-quality frame should be very strong and will not loosen or break due to slight collision or stretching. When glasses are made, they are generally checked for firmness through a manual destructive twist test. Of course, it is not recommended that consumers use this method when purchasing. They mainly use the 1st and 2nd methods. High-quality glasses brands will also have strict requirements in this regard, so choosing glasses from high-quality glasses brands is also a good way.
In general, through these three aspects, we can more accurately judge the quality of the welding process of a frame, and thus the quality of the frame.
How to know the quality when wearing glasses: high-quality materials are used
How to judge the quality of acetate glasses frames. High-quality acetate eyeglass frames are usually made of high-quality cellulose acetate, such as Mazzucchelli, Jinyi, Jimei and other acetate brand. Similarly, high-quality metal glasses or titanium glasses will also choose high-quality materials with more toughness and smoother surfaces. These high-quality materials have better wear resistance, impact resistance and flexibility, which can ensure the service life of the glasses frame. When selecting, you can observe the gloss and texture of the frame. high-quality frames usually have better gloss and smooth surface. High-quality acetate glasses frame usually have better craftsmanship details. For example, the joint between the mirror ring and the lens should be tight and seamless, the connection between the hinge and the frame should be clean and tidy, and the metal parts should have a smooth surface and a uniform coating, etc. In addition, branded glasses usually have the brand logo engraved on the inside of the temple, which is also a basis for judging the quality of the glasses frame. A good brand will tend to use better quality materials in manufacturing their glasses.
How to know the quality when wearing glasses: check the surface workmanship of glasses
Today's glasses are often not made of one kind of material. For example, there are other metal accessories in the acetate glasses, or there are acetate parts in the metal glasses. To judge the quality of these metal parts, the quality of plating is one of the keys. When judging the quality of plated surfaces, we need to pay attention to several key criteria. First of all, gloss is an important indicator to measure the quality of electroplating surfaces. Good gloss can show the sophistication of the electroplating process. Secondly, the uniformity of the coating cannot be ignored, which is related to the aesthetics and practicality of the product. If you find obvious thickness unevenness or color differences in the coating, it means there is a problem with the electroplating process. Finally, adhesion is the key to evaluating whether the coating is strong. Only when there is sufficient adhesion between the coating and the substrate can the durability of the product be ensured in daily use. Through careful evaluation of these three aspects, we can accurately identify the sophistication of the electroplating process and then judge the quality of the product.
How to know the quality when wearing glasses: check if you are using good quality lenses
When selecting lenses, their transparency, refractive index and coating are all important considerations. Transparency is the basic criterion for evaluating the quality of a lens. A good lens should be clear and transparent, without chromatic aberration and impurities, and can effectively prevent light scattering and provide clear visual effects. The refractive index is related to the thickness and comfort of the lens. High-refractive-index lenses are thinner and have better visual effects. As for coatings, high-quality lenses usually have anti-reflective, anti-scratch, and anti-UV coatings, which can increase the service life of the lenses and protect your eyes. In general, by observing these three aspects, you can basically judge the quality of a lens.
How to know the quality when wearing glasses: testing the durability of glasses frame
Durability is a key factor in frame quality, and the choice of material directly affects the durability of the frame. Among the many materials, metal and acetate are the most commonly used materials for making frames. Metal frames are popular for their excellent wear resistance and strength, especially titanium glasses, which are not only durable but also lightweight, making them ideal for daily wear. However, metal frames also have their drawbacks, such as being prone to rusting in humid environments or causing discomfort to some people with sensitive skin. Of course, the IP plating layer of titanium glasses is much stronger, is not easily oxidized and corroded, and is less likely to cause allergies to the skin. Acetate glasses are one of the most popular glasses currently. They are rich in color and diversified in styles, and are easy to meet individual needs. For example, fashionable acetate sunglasses are very comfortable and match with clothing. However, acetate glasses have relatively weak wear resistance and are prone to aging and breakage. Their service life is usually not as long as metal glasses frames and titanium glasses frames.
In general, no matter which material frame you choose, you need to consider its durability and comfort in contact with the skin according to your personal living habits and working environment. At the same time, the maintenance methods of different materials are also different. Reasonable care can effectively extend the service life of the frame.
How to know the quality when wearing glasses: Is it comfortable to wearing glasses
When we talk about the quality glasses frames when wearing glasses, the actual fitting experience is the key to judging. After all, no matter how great the design, it’s hard to call the frame great if it’s uncomfortable to wear.
1. Whether the frame is ergonomic. When trying on glasses, check whether the lenses are in the right position, whether the curvature of the frame fits your face shape well, whether the length of the temples is appropriate, etc.
2. The weight of the glasses frame. A pair of lightweight glasses will not put too much pressure on the bridge of our nose and behind our ears even if worn for a long time, ensuring that we can enjoy reading or working easily and happily.
3. The comfort of the nose pads is also very important. A well-designed nose pad can adapt to different nose shapes, provide stable and comfortable support, and prevent glasses from slipping or leaving indentations on the bridge of the nose.
Therefore, to know whether the quality of the glasses frame is good when wearing, we must try it on ourselves to feel the weight of the frame and the comfort of the nose pads to ensure that our glasses not only look stylish, but also give us a comfortable wearing experience. Of course, everyone has different needs for glasses. Some people are more fashion-conscious, while others prefer the thicker feel of glasses. For example, many people in Europe and the United States like thick acetate glasses. Therefore, in addition to paying attention to comfort, what you like is also the best.
