How long will the titanium frame last?
Titanium and titanium alloys are often used to make the most durable frames. Their strength is comparable to that of stainless steel. Medical facilities use titanium to make medical implants such as heart valves, showing just how durable the metal can be in extreme environments. Look at the maintenance between quality and use. Good glasses electroplating after three processes, the first is in the glasses or pure raw materials, plating a layer of an adhesion layer, used to attach the plating color layer. The second is the electroplating color layer. The third one is that after the electroplating color layer, another layer of electroplating protection is transparent. The electroplating of glasses through three processes can ensure that the glasses are not easy to lose color and damage in about 5 years. Now the glasses electroplating basically omits the processing of the last layer of the color protective layer, so the service life is about 3 years.
What Are Trivex Lenses?

How to maintain a hard-coated lens?
The hard-coated resin lenses can be identified by the sound of the tabletop tapping and the color brightness of the lenses. The lenses, which sound clear and have bright edges, are hardened. In daily use, avoid overheating environment. Avoid contacting with alkaline liquid, so as not to cause damage to the lens. And this damage is usually not formed in an instant.
