glasses frame material

The material of glasses has a decisive influence on the comfort and design of the glasses.

Starting from the natural materials of Genesis, today chemical and metal materials have also been added, and the situation is now like a million flowers. Each type has its own characteristics, and it is now possible to choose the material that suits your style.

Celluloid is probably the most famous chemical material. It is the first artificial thermoplastic resin in history, having been developed as a substitute for ivory. Acetate, which was developed later, is now mainstream, but because of its impact, plastic frames are sometimes collectively called cell frames.

On the other hand, titanium is rapidly gaining popularity among metal materials.

It is lightweight yet durable, making it an ideal material for glasses. Nowadays, the variety of titanium-based materials has increased, and manufacturers are competing with each other by combining other materials and processing technology.

Born from the development of an ultra-lightweight bulletproof protector by the U.S. Army.

It is a durable material that is approximately 10% lighter than polycarbonate and does not easily crack or break even if it deforms under pressure.

It is a material used in F1, space development, weapons, etc., and its greatest characteristics are its outstanding strength and durability.

Generally, it is classified into dry carbon, which is expensive, and wet carbon, which is widely distributed.

A nylon resin developed by a Swiss medical equipment manufacturer (EMS) that is lightweight yet has excellent elasticity and restoring power. Since it was developed for medical use, it is also extremely safe.

It is a substance manufactured mainly from petroleum, and is an essential material for eyewear, sometimes used as lenses and sometimes as frames, and is also called synthetic resin.

Although plastic has disadvantages such as low heat resistance and susceptibility to scratches, it also has advantages that more than compensate for these disadvantages.

It's extremely light, strong against impact, and doesn't break easily. Advances in technology have also made it possible to dye eyewear in a variety of colors, making it popular as fashionable eyewear based on thick frames.

Note that these plastic glasses are still called cell frames even now that they are made of acetate, a relic of the fact that celluloid glasses were once made of semi-synthetic plastic.

The oldest synthetic resin created in England in 1856. Made from natural materials such as cotton and pulp, it is hard and shiny, yet warm to the touch.

Coupled with its ease of shaping, it has been used as an alternative to tortoiseshell and ivory in products such as combs, guitar picks, musical instrument parts, and table tennis balls.

In particular, celluloid products have long been popular in fountain pens, where the fit in the hand is important, and eyeglass frames, where the comfort of wearing the pen determines how comfortable it is.

However, because it is highly flammable and requires great care when handling, it has recently been replaced by safer acetate.

Pure celluloid frames are a rare material and are only sold by domestic brands.

A lightweight alloy that is extremely resistant to rust and has a corrosion resistance almost equivalent to that of platinum.

Because of their strength and lightness, alloys made from materials such as aluminum and copper are used in a wide variety of products, including passenger planes, automobiles, forks and spoons, and eyeglass frames.

In the 1980s, when titanium frames were released, there was no requirement for quality labeling, so even frames with only a small portion of titanium were distributed on the market as titanium frames.

Although frames made of pure titanium now exist, the most widely available type is β-titanium, which contains aluminum, vanadium, etc.

It is an element with atomic number 13 and is the third most abundant element in the earth's crust, after oxygen and silicon.

Because it is soft and malleable, it is easy to process, so it is used in many industrial products, including 1-yen coins, cans, pots, aluminum sashes, and car bodies.

Approximately 60% of titanium in terms of specific gravity.

As a metal, it has long been used as a material for temples in eyeglass parts because of its lightweight properties.

As the name suggests, alloy steel is resistant to corrosion (stain).

Usually refers to an alloy of iron mixed with about 10% chromium.

Due to its excellent corrosion resistance and high strength, it is used as a material for many metal frames.

Stainless steel sheet frames are now common, making use of the elasticity of stainless steel to improve fit.

A new material for eyeglass frames, along with titanium.

Its specific gravity is 1.8, which is two-thirds that of aluminum, one-third that of titanium, and one-fourth that of iron, making it the lightest of all practical metals.

It exists infinitely in the earth's core as a mineral, and is also dissolved in seawater, making it the eighth most abundant metal on earth.

Furthermore, it has excellent vibration and shock absorption properties and is easier to recycle than plastic.

Therefore, a durable and lightweight frame that can withstand intense exercise is an ideal material for sports glasses.

Oakley Inc.'s Mag Frames are sports sunglasses that are both functional and stylish and are loved by many top athletes.

A new material developed at the Toyota Central Research Institute, a think tank of the Toyota Motor Group, this titanium alloy has both low elastic modulus and high strength, which were previously thought to be impossible with metal materials.

Although it is a metal, it is soft and pliable like rubber, and has high strength and unbreakable characteristics, so it is often used in medical devices such as automobile springs and artificial bones.

Furthermore, its properties make it ideal for glasses, so it has attracted attention in recent years as a material for temples and other parts.

A highly ductile precious metal that is extremely soft and can stretch up to 1 gram per square meter.

It is resistant to corrosion and can maintain its beautiful glossy color semi-permanently.

This metal was first used as an ornament, and was also used in eyeglass frames, but pure gold (K24) was too soft, so gold alloys such as K18 and K14 mixed with silver and copper were used for commercialization. There are many things to do.

Eyewear that uses natural wood for the frame.

The warmth of natural materials and the splendid patterns and luster created by the grain of the wood combine a sense of texture and luxury that is not found in metal frames.

It is flexible enough to absorb half of its volume in water, and weighs less than aluminum, titanium, and magnesium.

Each frame is carved and polished by a craftsman, and the more you use it, the more it blends into your face, creating a unique texture.

It is attracting attention as the ultimate frame material that only the Japanese could create.

As the name suggests, it is a buffalo horn.

It has been widely used as a frame material for several years.

Because it has a strong impact and presence, it is widely recognized as the material of choice for those who hang it.

The colors range from pale beige to jet black, and they feature unique patterns.

White collars also exist, although they are extremely rare.

It is made of precious natural materials and has a unique and indescribable texture, making it a representative high-quality frame.

Tortoiseshell is the shell of a sea turtle called hawksbill that migrates around the equator.

It has a translucent red-yellow color with agricultural brown spots, and because it is easy to process, it has been valued around the world as a material for crafts and ornaments since ancient times.

Nowadays, commercial transactions are prohibited under the Washington Convention, so they are extremely rare.

As a protein material, it has a high affinity for the human body and is suitable for eyeglass frames, but it is sensitive to sweat and hair products, so it must be cleaned with a dry cloth.

Because it contains Niwaka, it is possible to repair damage by applying heat and crimping it, and it can be polished to restore its luster, making it attractive for continued use.

leather.

It is made from the skin of mammals such as cows and pigs, or reptiles such as snakes and crocodiles.

It is often used in clothing and accessories such as coats and shoes, and in recent years it has also attracted attention as a material for eyewear.

It is highly durable, and the more you use it, the more it becomes glossy and the texture increases.

Leather is classified into natural leather, which is made from tanned animal hides, and synthetic leather, which is made by bonding resin to a base cloth to resemble natural leather (Clarino and Ecsaine are typical examples).

Natural leather has an attractive texture unique to natural materials, but it is sensitive to moisture and is susceptible to rain and sweat, so be careful when wearing this type of eyewear in the summer.

On the other hand, synthetic leather is water resistant and is more affordable than natural leather.

The drawback is that it easily deteriorates, and it cannot match the unique texture of natural leather.

An alloy with a bright white color similar to platinum that is resistant to rust and has excellent strength.

It was developed by the Japanese Shintaro Kato in 1930 and spread all over the world.

Currently, it is not produced in Japan, and most of it is imported from Germany.

This metal, commonly known as ``Sunpee,'' is suitable for eyeglass frames because it does not discolor due to sweat or hair products.

Many people prefer the soft platinum color that appears on the surface when polished, and it was used as a mainstream eyeglass frame until the 1970s.

It is also widely used in the medical field, including as the material for silver teeth used in dental treatment.

In recent years, titanium, a metal that has similar properties but is lighter, has come into circulation and replaced it in the market.

A typical plastic that was developed in the late 1960s, before it was replaced by acetate.

Its raw material is epoxy resin.

It was highly valued as a frame material because it was transparent, shiny, lightweight, and did not change over time. It has the characteristic of bending when heated and returning to its original shape when cooled.
