The superior properties of titanium glasses
They are light, around 40% of stainless steel. The hardness is high, about twice that of stainless steel and common steel, twice that of iron, and six times that of aluminum. In a world of ultra-low temperatures, titanium becomes harder and more superconductive, while steel becomes weaker and less capable. They have corrosion resistance, with no rust. Titanium does not rust in the sea for five years, while steel corrodes and deteriorates in seawater. The thermal conductivity of titanium is about the same as that of stainless steel. They are non-allergic materials. Titanium is a harmless material to the human body. More because it does not have an allergic reaction to the human body, it is one of the few metal materials used in medical science.

What Glasses Are Made Of?
In general, most glasses are made of plastic lenses. Why are glasses lenses made of plastic? In fact, plastic glasses are lighter than traditional glasses lenses used in eyeglasses, which means they are more comfortable to wear. At the same time, it is easy to apply lens coatings like anti-reflective to plastic lenses.
Besides, children’s glasses are also made of plastic because it is more resistant to impact. There are four main types of plastics used to make eyeglasses and sunglasses lenses which are plastic, Trivex, polycarbonate and high-index plastics.
The plastic lenses made from CR-39 were first introduced. CR-39 is an abbreviation for Columbia Resin #39, the 39th plastic of that type made by Columbia Resin.
Then the polycarbonate glasses were invented. Polycarbonate became out of this world once it found use in aeronautics. Polycarbonate is a type of plastic that can be produced as transparent and easily shaped, making it great for glasses lenses. Polycarbonate is impact resistant so that they are a good lens choice for kids. And the polycarbonate lenses have 100% UV protection.
Next, high-index lenses are available. High-index lenses have a high refractive index with a thin lens. Although high-index lenses are thinner, they are heavier due to the higher density of these plastics.
So, what glasses are made of? Most glasses are made of plastics. Then how are glasses made? To get the answer, keep on your reading.
Why choose an acetate frame?
(1) Lightweight and comfort
As one of the daily necessities, the lightweight acetate frame will not bring a heavy burden to the bridge of the nose. Even if you need to wear glasses all day, you will not feel too much discomfort.
This is the key factor that makes acetate frames stand out from traditional plastics or other materials. Acetate frames are made by cutting, molding and polishing multiple pieces of material, which makes them as strong as metal and ideal for eyeglass frames.
(3) Various design
The cellulose acetate spectacle frame design is the most fashionable. The surface layer of the traditional plastic frame is usually sprayed with colors and patterns. It may have a nice design or color. But because it is the only surface, daily use will cause its surface color and pattern to fade. After a year or even a few months, their appearance may not be as good as before. Unlike plastic spectacle frames, acetate makes the design easier to retain. The acetate fiber sheet can be designed with colorful patterns, different layers, and many colors. The embedded design can maintain its characteristics more effectively without spraying or painting.
Acetate is comfortable, weight-light and fashionable, and meets all your needs. Therefore, it can be said to be the best material for making spectacle frames. Therefore, the next time you decide to buy a new spectacle frame, please consider using a spectacle frame made of acetate.
