The Identification of the Quality
The frame that has good elasticity is usually of better quality. The frame that has a smooth and shiny coating is better in quality. If the solder joint is smooth, small, and uniform, the quality is better. The parts of the sunglasses are assembled closely.

Pure copper rust contains bacteria that affect the skin and can cause breakouts or skin irritation. High-end glasses are made of alloy materials with lead and nickel not exceeding the standard. Low-end and cheap glasses may not contain environmentally friendly alloy, which will do harm to the human body if it rusts.
