Lens anti-fogging agent

To be specific, a layer of the anti-fogging agent is sprayed (coated) on the surface of the lens to form a dense, absorbent, ultra-thin, and ultra-transparent biological coating. The coating chelates the droplets inside the coating (chelating means processing the material into a digestible form) to form a continuous and supper transparent chelating coating, which converts the droplets into a transparent micro-glass layer, thus preventing fogging. Spray anti-fogging agent on the surface of the lens, and then wipe evenly with an ordinary lens cloth. It can be used on most lenses. They are easy to use but have relatively short anti-fogging time. During use, the lens should not be wiped or washed. Long time use will affect the lens life.


Look at the quality of the frame.

Put the glasses flat in front of your eyes, and see if the color of the temples is different in-depth or light under the same light intensity. Sometimes, due to the mistakes in processing, the color asymmetry of the left and right temples will appear.Technology is the quality assurance of the frame, and a frame of fine technology is often reflected in the details.Pay more attention to the welding point near the metal frame to see if there are cracks.

The thermal effect during welding changes the stress structure of the material, or the weld defect, material fatigue, and so on will make it easy to fracture.Attention should be paid to see if the two sides of the stipules of the lens frame are symmetrical and if the fixation is safe.



Driving Glasses - S MARCO

S MARCO professional driving glasses and S MARCO professional radiation glasses have become a new favorite family.S MARCO professional driving glasses have unique functions, opening a new page of driving glasses. The biggest advantage of S MARCO glasses is that it has its own patent in professional driving glasses, and the technology adopted is nano-polarized light technology. In addition, the driving glasses designed by the S MARCO team are based on Oriental faces, car conditions, and driving habits. With stylish style, they are comfortable to wear, functional and practical, very suitable for Chinese people to use.


A saddle bridge is a type of bridge.

The bridge of the nose can make your nose look slimmer. There are two main types. The keyhole distributes the weight of the glasses to one side of the nose rather than the top. It's a good choice for those with a broad nose. The Keyhole Bridge is old-fashioned in the classic style, like a Keyhole. This design creates a small gap in the top part to give the impression of space, thus making your nose look smaller. Saddle bridge is a more modern style and usually goes around your nose with almost no gaps at the top. This close contact will make your nose look tighter.



Choose clear glasses with the right materials for kids.

A critical point for children to choose frames is to think about the weight, to avoid wearing for a long time, or they will be uncomfortable, unstable, easy to slip. It is recommended to choose an ultra-light plate or TR90 lens frame, which has good chemical properties, good thermal stability, with no deformation, good recovery, and no side effects, lightweight, and convenient material.


Why does shape memory alloy have memory ability?

It starts with its microstructure. When a metal is solid, its atoms are always arranged in a regular way, forming a lattice. Under different conditions, such as temperature, metal may have a different structure, in which case it is said to be in a different phase. The change from one phase to another is called a phase transition. The properties of a metal change during a phase transition. The temperature at which a metal transforms is called the transition temperature. The difference between a shape memory alloy and other metals is that the phase transformation process in a shape memory alloy is reversible under certain conditions.

Progressive multifocal glasses are more powerful.

On the premise of the dual vision correction effect, the progressive lens has more stable and complete functions. They provide lasting clear vision. Because the added value is continuously and slowly increased in the related area, the wearer can get a lasting clear vision from the far place to the near place through the progressive glasses. The appearance is better than that of bifocal and trifocal lenses, and there is no subplate dividing line.
