Metal frames are suitable for wearing.
For the eyeglass frames made of metal or alloy, after rigorous processing and gold plating, the color and luster of the surface reach a certain brightness. And it will be very beautiful to wear. Metal glasses have the benefits of solid, light, and beautiful shapes. The metal frame basically has a nose pad and the nose pad is a movable side that adapts to a variety of nose shapes. The end of the temple is covered with a plastic cover, which is beautiful and protects the skin.
Sunglasses
Sunglasses have a visible light transmittance of about 20% and can absorb ultraviolet and infrared rays well. It also has a variety of colors such as light green, light gray, light brown, etc., used to protect in different occasions. Among them, light gray lenses have little effect on color recognition. Light brown glasses make the blue sky look darker and reduce the transmission of green light. Light green lenses reduce the transmission of red light.
Sunglasses not only have a wide range of varieties, but with the improvement of decoration and health care effects, their scope of use has become more extensive. As the time to update sunglasses can be rapid, fashionable men and women would love to have multiple sunglasses to match clothes to satisfy their pursuit of fashion.
The characteristics of metal material
The material of metal glasses frame chooses some kind of metal material or alloy to make mostly. Most of the copper alloys are treated as the base material and then have surface treatment processing. Then there is the recent rise of pure titanium frames and those made of memory alloy. Metal frames are usually equipped with nose pads, which are movable to accommodate a variety of nasal shapes. The end of the temple is often covered with a plastic cover, not only beautiful but also to protect the temple and skin.

How to Tell If Your Progressive Lenses Are Correct?
When you can’t read with your progressive glasses, you can try this way. Hold something you want to read in your hands and lower your look with your eyes. But please note do not move your chin down as you look down. Then look down at something to read but do not lower your chin. Look at something you want to read. Rotate your head to the left and right and right with one eye at a time. If you can read in a rotated position, the reading zone is out of place. If you can’t read at all, the progressive glasses may be wrong.
Evolution of hard coating technology
The first generation of the use of hard coating technology began in the early 1970s, the quartz material is deposited on the surface of a resin lens under vacuum conditions, form a very hard anti-wear film. However, due to the mismatch between the thermal expansion coefficient and the film base material, it is easy to delaminate and crack the film. Instead, it forms the mottle on the surface of the lens, and the effect is not optimal.
The second generation of hard coating technology is the use of the 1980s. The surface of the resin sheet is coated with a material with high hardness and not easy to be brittle and cracked by an immersion process. At this time, anti-reflection coating lenses had appeared and gained the recognition of consumers, but the mismatch between adding hard coating and anti-reflection coating still caused serious lens wear.
The third generation of hard coating technology was developed in the 1990s, mainly in order to solve the problem of wear resistance after coating resin lenses with an anti-reflection film. The hardened material evolved into a polymer organic matrix material.
Fourth-generation coating technology is dominated by silicon atoms, in which the hardened solution contains both organic substrates. It contains inorganic ultrafine particles, including silicon elements, which make the hard coating not only tough but also hard.
MODELE glasses
MODELE makes each pair of glasses with the attitude of creating artworks. The fastidiousness of materials and strict requirements on details is the premise and warranty for MODELE to enter the high-end field. The temples of MODELE glasses are made of natural cattle horn, which is made by three processes with a comfortable feel and warm color. The nose pad is made of natural jade powder to design the proper radian of the human nose bridge and reduce the pressure on the nose bridge. The special jade powder material can more effectively inhibit the growth of bacteria.
