It is a brand of lenses produced by Shenzhen Chuangsite Industrial Co., Ltd.

Yisuzun lenses are good, the lenses belong to Hengdian Optical, and they are cost-effective. How to choose the best lenses:

1. Lenses can be divided into thin and thick ones. At the same power, thin lenses are lighter to wear and exert less pressure on the bridge of the nose. You will not feel particularly tired after wearing them for a long time. However, thinner lenses are generally more expensive, so when purchasing, you should choose the one that suits you reasonably.

2. Glasses will often accompany us, and they are inevitably prone to wear and bumps. We need to choose lenses with better wear resistance and anti-fall properties. Such as resin lenses or PC lenses. Generally, glass lenses are not chosen because they are less safe and can easily hurt your eyes if accidentally broken.

3. The refractive index of the lens is not the higher, but the appropriate one is chosen based on the depth of the degree. The deeper the degree, the better the refractive index, but the price also needs to be based on one's ability.

4. There are also anti-blue light and non-anti-blue light lenses, if you often need to face computer work. Or friends who often watch TV suggest choosing anti-blue light lenses to reduce the damage of blue light to the eyes.

5. When wearing glasses, you need to go to a regular optical shop for fitting. You cannot buy glasses by yourself to prevent further damage to the eyes caused by wearing inappropriate glasses.
