The spirit behind celluloid glasses

Because celluloid material is flammable, it cannot be mechanized and basically needs to be created by hand, which forms a unique set of handcraft modes of Japanese crafters. Today, there are only a few celluloid factories in Japan, and the unique manual process and production are relatively small. This makes celluloid handmade glasses even rarer and more valuable. Celluloid was originally a very common and cheap material, even with a certain degree of danger, but because of the unique craftsmanship of skilled craftsmen, its performance was brought to the extreme, so that celluloid glasses became unique and sought after by some people. The material of the frame is an important factor that determines the comfort of the glasses. While ensuring comfort, people hope that the glasses can have a decorative effect and play a role in clothing matching in different scenes.


The principle can be followed when choosing glasses for people with round faces

Choosing the right frames is not an easy task. Choose a color closer to your skin or lighter than your eyebrows for a more natural look. In reality, there is no exact answer to choosing glasses based on face shape. The rule to follow when choosing glasses for a round face is to make up for the lack of a round face by choosing an angular style. The vertical lines of the frame should be narrow.



Cellulose Acetate

Acetate is a kind of thermoplastic resin obtained by esterifying acetic acid to acetic anhydride under the action of a catalyst. Acetate is resistant to water, gasoline, mineral oil, and lipids, weak alkaline solutions, and acids, excellent weather resistance, not resistant to ethanol, strong acids, and strong alkaline solutions. During thermoforming, it is very necessary to dry the material before forming. Acetate was born in the early 20th century, and was successfully trial-produced and industrialized by the UK in the early 1920s. At present, it is the second-largest variety in cellulose fiber after viscose fiber. Acetate can be used to make textiles, cigarette filters, film bases, and plastic products.


What are polarized lenses for?

Polarized lenses contain a layer of polarizing plates in which molecular chains form a light-grating structure in which dichromatic pigments, which absorb polarized light, are evenly distributed. A beam of light is absorbed when it vibrates in the same direction as the bars of the molecular chain of the polarized lens. The grating direction formed by the molecular chain of the polarizer is the axial direction of the polarizer, which is generally horizontal. When polarized lenses are worn, they absorb all the light that vibrates horizontally, thus absorbing the glare and preventing it from reaching the eyes.

Is titanium alloy necessarily worse than pure titanium?

In the common case, the introduction of a titanium frame will have a detailed material label, what titanium and what material is it made of, such as titanium nickel alloy, titanium aluminum vanadium alloy, and so on.

The composition of titanium alloy determines the quality and price of the frames.A good titanium frame is not necessarily worse or cheaper than pure titanium.It is difficult to ensure the quality of titanium alloy which is very cheap in the retail market.In addition, titanium alloy is not to reduce the cost, but to improve the performance of the material.Usually, the memory frame on the market is made of titanium alloy.



Semi-rimless glasses give you a wider view than full-frame glasses.

It is believed that many people who wear semi-rimless and full glasses will have experience greatly. Because semi-rimless glasses have no frame at the bottom, our view expands as we look down, unlike full-rimmed glasses. When looking down, the line of sight is blocked by the lower half of the frame of the glasses, which is very inconvenient.
