பழங்காலத்திலிருந்தே மக்கள் சுய பிரதிபலிப்பை வரிசைப்படுத்த முடிந்தது. ஆரம்பத்தில், நீர் ஒரு பயன்படுத்தப்பட்டதுகண்ணாடி. From the Yin and Shang Dynasty to the Tang, Song, Yuan, Ming and Qing Dynasties, the கண்ணாடி for self-reflecting evolved into a bronze கண்ணாடி. The earlier glass கண்ணாடிs in China appeared in the Ming and Qing Dynasties. It was brought from Europe by missionaries who came to China. This European-style glass கண்ணாடி has to go through tens of thousands of miles of sea roads and bumps all the way. Taking into account the fragility, the கண்ணாடி surface is generally narrow and easy to carry; the கண்ணாடி is mostly used for shaving and shaving, and the கண்ணாடி surface is only enough to shadow the partial beard.Then, with the passage of time, the silver கண்ணாடி used by most of us came into being. With the development of technology, the function of the கண்ணாடி is only self-reflection, it is more intelligent and more humane. More functional, such as: anti-fog, watch time, measure temperature, watch TV, etc. The material of the கண்ணாடி has also been upgraded from a silver கண்ணாடி to an "environmental protection கண்ணாடி". This கண்ணாடி uses lead-free paint, which is a technical breakthrough of silver கண்ணாடிs. This kind of கண்ணாடி is called a lead-free and copper-free கண்ணாடி, also known as an "environmental protection கண்ணாடி.
