How To Choose Better Night Driving Glasses?
Choose and buy glasses to use a special night with anti - strong night driving lens. The demand is to block 80-90% of the strong lights and harmful lights, and at the same time to make the road more clearly. Choose glasses with thicker lenses, they are more durable and protect the eyes of drivers against irritation and accidental breakage. As common sunglasses and color-changing glasses are only suitable for daytime wear, wearing them at night will seriously affect the driver's vision.
Common light yellow night driving glasses can only block a small amount of light, and is not very suitable for night driving glasses standards. Therefore, in the choice of lenses of night driving glasses, we must do the selection and demonstration of the national authority of the formal institutions to test products, to achieve the desired effect in actual use. Don't buy products that are not up to standards from vendors. Such products not only do not block the lights but may affect the driver to see the road ahead, affecting the safety of the train operation.
How much do a pure titanium eyeglass frame cost?
For the plastic frame, without a fixed metal rod in the middle, the retail price of the exclusive store is 30 dollars or so. Resin-coated metal frames are inexpensive, 35 to 85 dollars in the store. Because pure titanium is more difficult to make, and the material is more expensive, the frame price often starts from 50 dollars. For example, the ordinary Seiko pure titanium eyeglass frame is about 85 dollars.

Characteristics of titanium frames
Titanium is widely used in the eyewear industry because it is not easy to deform, fade and has strong stability. The glasses frame made of titanium can highlight the noble taste and elegant temperament. The glasses frame made of titanium can be divided into pure titanium, titanium alloy, and beta-titanium frame three kinds. To learn about titanium frames, how to identify pure titanium frames?
Titanium frame has the benefits of low density, high strength, good mechanical properties, and strong corrosion resistance. The frame is very light and not easily corroded by moisture. However, due to the poor process performance of titanium alloy, machining is very difficult, the glasses frame made of hydrogen, oxygen, nitrogen, carbon, and other chemical impurities are more absorbed. The wear resistance of titanium alloy is relatively poor, and the production process is relatively complex, so the cost is relatively high and the workmanship is relatively complicated when using this material to make the spectacle frame. The price is much more expensive than the common spectacle frame.
Which are better, elastic or inelastic frames?
The more elastic the frame, the better, because only good elasticity can be naturally worn on the face, not sliding. It is comfortable. On the contrary, when you wear it, the temples are open. Because without elasticity, they can't go back to their original state. When you put it on, it creates a feeling of slipping and sagging. We often see that some people repeatedly with hand glasses. This is this problem. In order to pursue good elasticity, high elastic materials such as titanium and stainless steel are widely used in the production of spectacle frames.
