Production technology of progressive lenses
In addition to the evolution in design, the production technology of progressive lenses is also constantly improving: the most representative one is the free-form technology.

For now, progressive lens design is done on the inside surface of the lens by a computer-controlled lathe, as if a master engraver could carve a piece of stone into a work of art.
Benefits of glasses without nose pads
Glasses without nose pads are mostly used for sheet materials because the sheet material is lighter and not allergic. From the viewpoint of aesthetics and comfort, no nose pads are more suitable. Glasses without nose pads have a relatively small contact area with the bridge of the nose, so it is not easy to have obvious indentations on the bridge of the nose, while glasses with nose pads will have obvious indentations after wearing them for a long time.
In addition to supporting the frame, the nose pad has another function to prevent allergies and avoid discomfort caused by allergies to metals or other materials. Whether it is better to have glasses with nose pads or without nose pads, depends on your personal situation. If your nose is sensitive to weight or the bridge of your nose is lower, you should choose glasses with nose pads. If you are particularly looking for beauty and don't want any marks on your face, then choose glasses without nose pads.
In fact, it is hard to say which one is better between nose pads and no nose pads. The key is to look at personal preference and wearing comfort. Generally speaking, a high nose bridge is suitable for choosing frames without nose pads. It is more suitable to choose the frames with nose pads for people with flat nose bridges in order to prevent the glasses from sliding off and affecting the visual effect.

What is the best lens material?
Early lenses were made of natural materials because they were easy to get. But natural materials have obvious drawbacks. According to records of the Qing Dynasty, Emperor Yongzheng wore crystal glasses given by the imperial court, which greatly improved the efficiency of reading documents. However, because of the cold nature, the crystal will make the temperature around the eyes low when wearing, and part of the crystal lens has color so that the light into the eyes becomes soft.
The quality of the eyeglasses chain stores is relatively stable and reliable.
As the eyewear chain enterprises spread across the whole city or across regions, they occupy a large share of the local market, and the resulting scale effect reduces their own procurement costs and greatly enhances the awareness of brand quality. Therefore, the procurement of eyewear products is critical. Those defective products are much less likely to appear in these chain optician stores, which naturally ensures that overall product quality improves.
