How to choose a spectacle frame
First of all, we must clarify what are the specific materials of the spectacle frames on the market. At present, the more commonly used glasses frame materials are sheet material, aluminum-magnesium alloy, natural wood, and bamboo materials. Of course, there are other materials such as titanium, TR90, and ULTEM.
Secondly, we have to make it clear that the texture brought by each different material is different, and each has its own advantages. For example, plastic glasses frames are made of sheet materials, which are characterized by easy processing and relatively lightweight. They are generally not easy to deform at room temperature. And the spectacle frame made of metal material is relatively strong, light, and beautiful. Therefore, to learn the advantages and disadvantages of each type of spectacle frame, we can meet our different needs according to each different material.
Why do spectacle lenses fog up?
The fog on the surface of the lens is essentially related to the saturation pressure and water vapor liquefaction. The air is full of water molecules, which are constantly doing irregular movements. When there is no temperature difference, water molecules keep hitting the surface of the lens and will keep bouncing off. The lower the temperature, the slower the speed of movement. Therefore, when water molecules hit the cold lens from the hot air, on the one hand, they move too slowly to fly out in time. On the other hand, because of the relatively low temperature of the lens itself and its vicinity, the water vapor will liquefy. As a result, more and more water will accumulate on the lens and form small droplets, eventually forming a foggy layer. As the lens heats up, the mist evaporates back into the air, and the fog disappears.
Why are titanium glasses so expensive?
