3, On the logo - look at the material.
Many frames will be framed on the temples, especially the precious metal frames of gold and titanium. Let's take a brief look at their logo.
(1) GF/GP: GF is a gold-clad frame, which is a frame obtained by welding thin gold sheets on other metal substrates; GP is a gold-plated frame, that is, gold is plated on other metals.
(2) Ti-P/Ti-C: Ti is a mark containing a titanium material, Ti-P represents pure titanium, and Ti-C represents a titanium alloy or the like.
QQ图片20180925101241By the way, what is the difference between titanium, titanium alloy, beta titanium, and memory alloy?
A. Pure titanium.
Titanium metal materials with a purity of more than 99% of titanium can be used as pure titanium glasses. The frame made of pure titanium material has excellent characteristics such as high melting point, light material, strong corrosion resistance and firm plating layer, which can ensure the two important performances of the eyeglass frame beautiful and durable.
B. Beta titanium.
It can be understood as another molecular state of titanium. Although the purity of β-titanium cannot be compared with that of pure titanium, its properties such as strength, fatigue resistance and environmental corrosion resistance are better than those of pure titanium.
C. Titanium alloy.
The definition of titanium alloy is relatively extensive, and any titanium-containing material may be referred to as a titanium alloy. Therefore, the quality and grade of titanium alloy frames are uneven, and the direct influence on the price of titanium alloy glasses is the composition of titanium alloy. The use of titanium alloy for making glasses is not to reduce costs, but to improve the application performance of materials.
D. Shape memory alloy.
Made of nickel, titanium, vanadium and other metals, it has superior elasticity. If the temples encounter external forces, the bending degree can exceed the BETA-titanium alloy and can be restored to the original state. Therefore named as shape memory alloy.
The difference in titanium prices is not just price, but more importantly, they each have unique processes and product properties. Therefore, it is not the frame of the material that the price is relatively high.

In recent years, there is also a TR material that is particularly popular.
TR90 is a memory polymer material that weighs less than half the weight of the frame. It reduces the burden on the nose and ears and makes it lighter and more comfortable to wear. The color is brighter and brighter than the ordinary plastic frame.
Impact resistance: Effective to effectively prevent damage to the eyes caused by impact during exercise.
High temperature resistance: It can withstand high temperatures of more than 300 degrees in a short time, and is not easy to melt and burn. The frame is not easily deformed and is not easy to change color, and the frame is worn longer.
The TR100 is an upgrade board for the TR90. Has a memory function.
The material is light and can float on the surface of the water, reducing the nose and the weight of the ears. It is elastic, stretched or stretched and then relaxed. It will quickly return to its original shape, not easily deformed and broken, and the frame is colorful. Stylish and easy to wear, it combines heavy and metallic textures.

After finishing the choice of frames and lenses, and then send you two small reminders.
A. optometry once a year
It is recommended that you need to re-opt the optometry every time you change the glasses. It is best to go to the ophthalmology department or professional optical shop of each hospital. In addition, with new glasses optometry, it is best to bring your old mirror, for the optometrist to make reference.
B. One pair of glasses changed two to three years
The average life cycle of glasses is two to three years. Ordinary myopia patients generally recommend to change glasses once every two years, because the degree may change, and second, because the mirror lens will wear scratches or film peeling for a long time, once the scratches are serious, it will obviously affect its optics. Corrective performance, continue to wear is not good for the eyes. Therefore, it is necessary to regularly maintain and inspect the glasses and replace them in time.

What shape of glasses is fit for my face shape?

https://www.zinff.com             It is a common problem, which puzzles everyone who wants to choose a pair of glasses, that how can I choose proper glasses to be fit for my face shape.             Many fashion magazine articles tell their readers that different face shape should choose different kinds of glasses.

If you have to put yourself in the "standard face shape", then you will meet troubles. More important is that the shape of your nose, eyes, and mouth also have great influences on how to choose a proper glasses.        Second, the hairstyle could change the contour of the human head, and the face shape under different hairstyles will

Why we found Zinff?

It was the lowest moment of my life. One day, I found my son’s eyesight had deteriorated. His glasses were muddy and mismatched, but he kept this from me for he was afraid that I couldn’t afford one. I was moved to tears and gratified to have such a considerate son. I insisted on taking him to the optical shop. I still remember the embarrassment when I found out the cost of the glasses was so high. From then on, I was determined to make the glasses affordable to everyone. For a long time, the eyewear industry has been widely criticized for its high prices. Some big companies keep prices artificially high to reap huge profits from consumers who have no other option. Opaque pricing and asymmetric information makes the consumer skeptical if the glasses are worth the money. Therefore, we founded Zinff, a fashionable online optical shop which is devoted to providing high quality, cost-effective eyeglasses and services. We have a professional optician center, highly qualified opticia
