The Structure of Various Sunglasses

As the sunlight intensity exceeds the adjustment ability of people’s eyes, eyes will be absolutely hurt. Therefore, people often wear sunglasses to protect their eyes when they are outside, especially in hot summer. In fact, wearing sunglasses also make people look cool. As we all know, sunlight in summer is strong and dazzling so how can a pair of sunglass prevent it from damaging people’s eyes? Obviously, the special function is closely related with its structure.

Although there are various sunglasses in the market, the structures for most of them are nearly the same. Staining lens is the essential part of sunglasses. The color of sunglass lenses can decide which colors they could absorb. Grey sunglass could provide protection against dizzy light. Both amber and brown sunglasses are quite popular and they can obsorb UV as well as other lights of high-frequency colors. Green lens could filter some blue and reduce dizzy light. Yellow or golden sunglass also can reduce blue which often causes dizzy light effect and allows other colors to pass through lenses. Polarization filter of sunglasses also reduces dizzy light. Sunlight and other lights from artificial light source usually vibrates and disseminates in all directions. In such case, light is considered as polarization and dizzy light occurs. But polarization filter of sunglasses can solve the problem. Half-silvered surface of sunglasses is a kind of thin reflective coating which can flash back half of lights reaching glasses and let the other half pass. The surface helps people see clearly.  However, the thin reflective coating is easily scratched. Sunglass is made of glass which is fragile. Therefore, the coating against scratching is put onto the sunglass to protect lenses. Back dizzy light is the common problem for various sunglasses and anti-reflective coating is indeed necessary.  UV could cause various diseases to people’s eyes so anti-UV coating is also put onto sunglasses.

Here are several points for attention to purchase a watch, and you could buy a watch with high quality by them.

First, we should check outer parts of the watch. We could check whether a watch is good or bad by examining its appearance which is obvious to us, at least, we should guarantee that it is good and complete from appearance.

Second, we could check the sensitivity of the watch. The sensitivity of the watch is very important, and if a watch does not have a good sensitivity, it means that there is something wrong with this watch. We could shake the watch that has stopped moving a little, and we could observe the movement of the second hand by means of the shaking strength, and if the second hand stops moving in a short time, it indicates that this watch has a high sensitivity and it could walk over after winding up enough.

Third, we should check the winding mechanism of the watch. The winding mechanism of a normal watch is loose, and when we are winding up, it is loose at the beginning, but it will become tighter and tighter, and when it could not be wound any more, it means that it is enough and the winding mechanism is normal, if we could hear abnormal noisy when we move the handle, it means that there is something wrong with the winding mechanism.
