There are so many kinds of glasses on the market now, especially the sunglasses.

There are also a few myopic sunglasses that indicate degree on market now to sell, do not pass because pupil distance and other indicators vary from person to person, if do not have the guidance of professional personage so, consumer had better not choose this kind of sunglasses that has degree.
How to wear sunglasses? Sunglasses are generally divided into light and dark categories and are made up of a variety of colors. Judge the quality of sunglass bad, the key should examine a few technical indicators such as top coke degree and prism degree, transmission ratio characteristic, surface quality and inner fault, assembly precision and plastic requirement. A good pair of sunglasses can help shade the sun and decorate the appearance. But in the market, the actual situation is not optimistic. Some vendors are taking advantage of consumers’ lack of knowledge about the quality of sunglasses by making them with shoddy, inexpensive window glass or other inferior materials. The uniformity of these materials is poor, containing streaks, bubbles and other impurities, can not block ultraviolet light, does not meet the physiological requirements of the human eye. What’s more, the use of poor quality plastic sheets with very low visible light transmittance but very high UV transmittance to make sunglasses harms consumers.
The lenses of color changing sunglasses darken when the sun’s rays hit them. When the lighting waned, it became bright again. This is possible because the crystal of silver halide is at work. Under normal conditions, it keeps the lens perfectly transparent. In the light of the sun, the silver in the crystal is separated, and the free silver forms small aggregates inside the lens. These small silver aggregates, irregular patches with interlocking teeth, do not transmit light but absorb it, which darkens the lens as a result. In the case of dim light, the crystals form again and the lens returns to its bright state. Many friends do not know what is the difference between pure titanium eyeglasses and titanium alloy glasses, pure titanium eyeglasses and titanium alloy eyeglasses frame how to distinguish better.
Touch weariness: Usually the specific gravity of the alloy frame is about 8.9g/cm3, the specific gravity of the pure titanium frame is 4.5g/cm3, because the weight of titanium material is equivalent to half of the alloy frame, it is relatively light by hand. This is one of the easiest ways to distinguish between titanium and non-titanium racks. Hinge joint: The pure titanium lens frame should not be directly in contact with titanium at the hinge part, otherwise it is easy to wrinkle the joint and the lens leg is not open. Two thin spacers are usually inserted into the hinge of a pure titanium mirror to separate the upper and lower hinges. Therefore, check the hinge has no gasket, is also a good way to identify whether it is pure titanium frame. Looking at the joint of the hinge from the inside of the frame, a small groove will be found, which is specially designed to facilitate the removal of the gasket.

You might be surprised to hear that sunglasses have been around for quite some time, dating back to prehistoric times. So, let’s pull back the curtain on these early forms of sunglasses. Imagine living in a place where the sun’s reflection off the snow could blind you. That was the reality for the Inuit people. They created snow goggles from caribou antlers, which had thin slits to allow minimal sunlight and prevent snow blindness. This clever invention demonstrates that necessity truly is the mother of invention.
Polarized lenses are made by placing a thin film of chemical compounds, usually a type of polymer, between two layers of a lens. These compounds are designed to absorb light of a specific polarization. During the manufacturing process, this film is stretched to align the long chains of the polymer. This alignment blocks light vibrating along the same direction as the aligned polymer chains, filtering out glare. What Polarized Sunglasses Do? Polarized sunglasses do more than make you look cool. They’re your ultimate shield against harsh glares. Remember when we talked about light becoming polarized when it hits a flat surface? Well, polarized sunglasses effectively block this reflected light, ensuring it doesn’t reach your eyes.
By caring for your glasses, you’re not just preserving a pair of eyewear; you’re safeguarding your window from the world. So, the next time you casually pull your shirt to clean those lenses, pause and reconsider. Your glasses deserve better, and now you know how to deliver that. In our daily lives, we often find ourselves squinting under the harsh glare of sunlight bouncing off car windows, roads, or bodies of water. We may reach for the closest pair of sunglasses, but not all sunglasses are created equal. Enter polarized sunglasses – the unsung heroes in combating intense glare. But what exactly does ‘polarized’ mean? Why should you consider swapping your regular sunglasses for polarized ones? And how can you tell if the shades you just bought are polarized?
