Silhouette
Because of its unique lightness, and its unique materials, the American space agency, NASA, took a fancy to it and designated it as space special glasses. Since 2000, it has accompanied astronauts on 35 space missions. With no frames, screws, or hinges, this is the new look that will forever be memorized as the Rimless Titan Minimal Art（TMA） glasses, which weigh 1.8 grams. In order to reduce weight and improve comfort, the EmPadsystem patent was invented, which improved the eyeglass beam and nose pad, further effectively reducing the pressure of eyeglasses on the nose bridge and making the eyeglass nose pad easier to clean.
Why are eyeglass frames are so expensive?
Plastic frames are often used for rimless glasses, but they are not very resistant to corrosion and break easily. The plate is a new type of plastic, and it is light and has high hardness, not easy to deform, but the surface is easily corroded by sweat. TR90 has features of wear resistance, good chemical resistance, solvent resistance, weather resistance, not burning, high-temperature resistance. Plastic steel does not contain any metal, but it is a kind of high-strength molecular material, lighter than TR90. They have a higher level in corrosion resistance and strength and other aspects. The frames made of good materials are more comfortable, durable, and textured in daily wear, and will not cause skin allergies. Plate, titanium, TR90, alloy are the most used materials on the market at present. The price is in dozens of yuan to hundreds, thousands of yuan.
TR90 spectacle frame
TR90 is a composite super-elastic resin material first invented by Koreans and used in the manufacture of glasses. Its characteristics are lightweight, excellent flexibility, and slightly lighter than pure titanium. After this material is being made into a finished product, it is non-adjustable. The application is basically injection molding. Koreans are the first to apply to glasses production, which has been popular for a few years, and then popular in the Japanese market. Now it is basically mass-produced in China. The high-end high-quality TR90 spectacle frames are produced in Shenzhen, and the low-end low-quality ones are in Wenzhou because they are much cheaper.
What Are Varifocal Glasses?
Varifocal glasses, also known as varifocals, varifocal lens, PLA, or progressive lenses, have a gradual change in strength from the top of the lens to the bottom with multiple focal points in between. Unlike bifocals, varifocal glasses have no specific area of lens strength, but progressive lens zones.
The way to look through varifocal glasses depends on what you want to look at. If you are looking at the distance, you look through the top of the lens. If you want to look at the close objects, you may need to move your eyes lower to keep the objects in focus. For the best close-up focus, you need to look through the bottom of the lens.
The benefits of varifocal glasses are that they do not need to buy or prepare 2 separate pairs of glasses or need to switch between frames for different vision needs.
However, if you wear the varifocal glasses for the first time, you may come across some problems.
How Are Glasses Made?
In this section, we will show you how glasses are made. Here are a few steps.
- Eyeglasses lenses are first made by an optician reviewing your prescription and taking a lens bank that closest matches your prescription.
- The optician puts the lens bank into a grinding machine and grinds it into a shape that matches your prescription even closer.
- Then the glasses lenses are edged and cut into a shape that fits the frame you chose.
- Last, put the cut lenses into a solution so as to protect them from scratches, then give them a tint and more.
After all steps are finished, the glasses are made successfully.
