How to Tell If Lenses Are Plastic or Glasses?
If you want to know if your glasses are made of glasses or plastic, the safest way is to ask the optician from whom you bought the glasses. If you do not want to ask the optician, there are several ways to differentiate them, such as sound, weight, and temperature.
Lightly tap the lens against your teeth or your ring. If the lens emits a high, ringing tone, it is a glasses. On the contrary, the plastic will have a low thud like sound when tapped.
Glass lenses are much heavier than plastic glasses and glass lenses feel colder to touch while plastic glasses feel warmer since it is a better insulator.
After learning what lenses you have, it is time to show how to remove coating from glasses.
Silhouette Glasses
Slim, refined and stylish are all words that could be used to describe the signature style of Silhouette, and the company is known for its rimless glasses design. They promote rimless glasses to the boundary without limits, with no frames, hinges, and screws. It is one of the few major manufacturers of glasses frames in Europe, making all its parts and assembling the products entirely in its own factory. They have created unprecedented product quality and an unmatched reputation in the eyewear industry.
Tortoiseshell is the important material of the frame.
The old metal frames used to be made of stainless steel or other alloys, and most of them have been phased out. The more popular modern metal frame is titanium metal frame, pure titanium, beta-titanium, memory titanium, and so on. In addition to being relatively light, it is resistant to corrosion and does not deform easily, especially used for the production of glasses or glasses frames. Because the color like amber gives a person a warm and delicate, luxurious and elegant feeling, so tortoiseshell glasses in the eyewear industry are a best-selling type of glasses.
What are bendable glasses called?
Bendable frames, or memory metal frames, are metal frames that can be twisted, bent, and shattered without breaking or losing their original shape. It's made of a kind of smart metal that has a memory. Its microstructure has two relatively stable states. At high temperatures, the alloy can be changed into any shape you want. Memory metals are mainly nickel-titanium alloy and other materials. The structure of these alloys varies with temperature in the solid-state, the shapes of these alloys can be changed as needed, and will automatically return to their original shape at a given temperature. One unique aspect is its ability to return to its original shape, although the frame has been twisted, bent, or crushed. They are lighter and more durable than traditional metal frames. The bendable frames are made of composite metal alloys for bending properties. These lenses can be twisted and bent, and when they are released, they return to their original shape.
What are keyhole glasses?
Keyhole glasses have a keyhole bridge. The keyhole bridge is shaped like a keyhole and is located on one side of the nose. Bridge glasses are one of the most beloved styles in the history of optics. The keyhole bridge has the shape of a keyhole. The keyhole bridge is arguably one of the most popular eyewear features. With the rise of acetic acid frames in the 1950s, keyhole glasses became widely popular. The ductility of the new material allows for a simplified manufacturing process, thus creating room for creative experimentation in the frame development.
The Disadvantages of Trivex Lenses
In this section, we will show you the disadvantages of Trivex lenses.
- Trivex lenses have less availability, especially compared with polycarbonate lenses.
- Trivex lenses cannot provide the same degree of thinness as high-index lenses.
- Trivex lenses are expensive than regular lens materials.
