Is it necessary to repair the glasses that are badly damaged?

If your glasses are badly damaged, think about getting a new pair. Maintenance is maintenance, not a replacement, so there are some traces of maintenance. The repair cost is far more than or can buy a new pair of glasses, so there is no need to repair them. For the kind of alloy that's used for cheap glasses and the kind of alloy that's used for high-end glasses, the texture of the welding is so different. There are differences in intensity. In order to make the cheap glasses strong after welding, it will definitely increase the welding marks (solder repair, etc.), so the marks will be obvious.


Do Blue Light Glasses Work?

When wearing blue light glasses, you may ask whether the blue light glasses really work. In fact, many users have the same troubles. To answer this question, some researchers have made research and have found that blue light glasses make it possible to remain fully engaged in our technologically advanced world, without taking on the negative effects of blue light.

With the blue light blocking glasses, you can focus on the task at hand without negative effects. Besides, with the blue light blocking glasses, you can even sleep well and reduce eye strain. You can also test your blue light glasses are real.



Are blue lenses good for driving?

Do not buy blue sunglasses, which cannot filter ultraviolet rays. In the choice of sunglasses, try to choose brown or gray. When driving a car, choose to wear sunglasses, and safety should come first. Wearing and viewing comfort is the most important indicator.

What are polarized lenses for?

Polarized lenses contain a layer of polarizing plates in which molecular chains form a light-grating structure in which dichromatic pigments, which absorb polarized light, are evenly distributed. A beam of light is absorbed when it vibrates in the same direction as the bars of the molecular chain of the polarized lens. The grating direction formed by the molecular chain of the polarizer is the axial direction of the polarizer, which is generally horizontal. When polarized lenses are worn, they absorb all the light that vibrates horizontally, thus absorbing the glare and preventing it from reaching the eyes.



Characteristics of Carbon Fiber Glasses

Carbon fiber frames have pretty impact resistance. Carbon fiber is made of carbon, the core element of diamonds. It is ten times stronger than iron, and it weighs less than steel. The maximum stress it can withstand before breaking is 7 to 9 times that of steel. Carbon fiber is more resistant to corrosion than metals like titanium. It has high-temperature resistance, radiation resistance, good elasticity. Carbon fiber is not only flexible, but durable, so it won't break if you drop it. Carbon fiber has many benefits, including high stiffness, high tensile strength, low weight, high chemical resistance, high-temperature resistance, and low thermal expansion.
