Is it cheaper to buy glasses online？
Online glasses matching adopts the operation mode of online platform and factory-style centralized mirror matching center, and returns all the huge site, labor, and intermediate costs saved in physical stores to consumers, providing better glasses matching the quality and lower product price! So, the price is cheaper.
Plate Frame
Glasses processed with acetate sheets become sheet frames. The plate frame is not easy to burn, the specific gravity is small, and the base arc is not irradiated by ultraviolet rays to change color. In addition, it has high hardness, good gloss, and durability, but it is not easy to bake and the temperature is 115-130 degrees. The style is more beautiful, and it is not easy to deform after wearing. The current market is that the plate frame combines the thickness of the plate and the metal texture, and combines different types of lenses to create fashion and personality. There are not only retro-style frames, but also popular frames, combining a variety of elements to create classic glasses frames. Its workmanship has undergone complex processes such as turning, grinding, and polishing, so it is relatively high-end.
Take Frame material selection seriously.
When choosing a frame, try to choose a light frame. At present, the glass frame material is relatively light titanium, tungsten carbon, TR90, and so on. Now based on the plate spectacle frame, the new plate spectacle frame implements thin processing, so the whole spectacle frame has become light up. You can use rimless light glasses. Usually, the nose pad will leave an indentation, possibly because the glasses are too heavy. Changing some light glasses can improve the problem of indentation of the nose pads.
Essilor Lenses
'Seeing the world better' is the goal that Essilor has always pursued, and 'people-oriented, winning with quality' is the basic point of Essilor's business philosophy. Essilor believes that the competition of talents is the foundation of all competitions. Only the personnel with professional ethics and professional ability can a company start from nothing and grow from small to large. The establishment of brand image and recognition by consumers can become a reality. Therefore, Essilor does not aim at a short-term profit, but focuses on the establishment of the company and brand, with long-term market share as the main goal. At the same time, they establish a good relationship with retailers and distributors, so that they can develop together for a long time, and pursue a real 'win-win'.
Essilor’s flagship brands include Varilux, Crizal, Airwear, etc. Varilux myopia lenses are mainly progressive lenses with super high refractive index and high-quality visual field, and the lenses are ultra-light and ultra-thin. Crizal lenses have excellent anti-fouling, abrasion resistance, anti-glare functions, and good light transmittance. Airwear lenses are PC lenses, and their chemical name is polycarbonate, which is a thermoplastic material. PC lenses are extremely tough and will not break (2cm can be used for bullet-proof glass), so they are also called safety lenses, which are currently the lightest materials used for lenses.
About industrial pure titanium
For the industrial pure titanium, titanium content is not less than 98%, containing a small amount of oxygen, nitrogen, hydrogen, carbon, silicon, and iron impurities such as dense metal. The labels are TA1,TA2,TA3,TA4. It's arranged by more and more impurities. The TA1 titanium content is more than 99.5%, and the price is not high. But no matter which links, for molding, welding, polishing, processing difficulty is very great.The price of almost all titanium alloys in the national standard is higher than that of pure titanium.
In reality, the price of β titanium is higher than pure titanium. Pure titanium is almost no elastic, but β titanium is not only elastic, and has the advantages of ultra-light corrosion resistance. β titanium does not have a specific composition. Memory titanium can cost tens or even tens of times as much as pure titanium.
Using memory alloy to make glasses frame is the use of its superelastic characteristics at a certain temperature (elasticity is several times that of stainless steel) and did not use its memory function. Compared to beta-titanium, memory titanium is so difficult to process. It is so elastic that shaping is difficult and impossible at room temperature, and memory titanium heat treatment is another difficult and even secret process.
Oval face with glasses of various shapes
The oval face is the most perfect face shape. Whether it is size, shape, or contour, it is a more perfect face shape There are many types to choose from, and there are basically no minefields. But be sure to pay attention to the size of the glasses. Sometimes the size of the glasses is also very important. if you are not careful, it will highlight the incompatibility of your facial features. So make sure your glasses are not too big or too small. You should judge the size according to their face shape.
What Is Polycarbonate Lens?
Polycarbonate was developed in the 1970s for aerospace applications and is currently used for the helmet visors of astronauts and for space shuttle windscreens. Polycarbonate lenses were introduced in the early 1980s in response to a demand for lightweight, impact-resistance lenses. Since then, polycarbonate has become standard for safety glasses, sports goggles, and children’s eyewear.
Polycarbonate glasses are thinner and lighter than regular plastic lenses. They provide 100% UV protection and are up to 10 times more impact-resistance than plastic or glasses lenses. Polycarbonate glasses also offer clearer and more comfortable vision if an anti-reflective coating is applied to the lenses, which can eliminate distracting lens reflections that interfere with vision, particularly when driving at night or in other low-light conditions when glare sources are present.
However, polycarbonate lens is a naturally soft material, making it more subject to scratching without adequate protection with a scratching-resistant coating. Polycarbonate glasses have high dispersion due to its low Abbe value of 30, causing chromatic aberrations.
