There's a polarizer that you can try on.
Polarized sunglasses lens is a laminated substance, generally composed of seven layers, the outermost two layers are anti-wear, the second and sixth layers are anti-ultraviolet, the third and fifth layers are to filter harmful rays, and the middle layer is the polarizing layer. The polarizing layer has a good UV protection effect, but it is not wear-resistant and easy to scratch. The polarizer can block the indiscriminate reflection of light, glare and irregular reflection of objects in natural light, and there are 300,000 linear molecular arrangements that are invisible to the naked eye in every 1 square centimeter in the inner part of the polarizer, and they are arranged in the same direction.
Compared with ordinary glass sunglasses, polarized sunglasses do not affect vision and will not cause chromatic aberration. At the same time, it can effectively avoid the damage of ultraviolet rays to the eyes.

Summary. The intensity of electric welding is beyond the range of human eyes, and if no protective measures are taken, it will cause burns to the eyes, cause electro-optic ophthalmia, cause damage to the corneal epithelium, and cause symptoms such as pain, photophobia, tearing, and foreign body sensation. Be careful not to rub your eyes to avoid more serious injuries, wear sunglasses when you go out, and avoid tearing and difficulty opening your eyes caused by bright light.
These diseases usually improve significantly after 48 hours, and the symptoms disappear completely after corneal epithelial repair. Therefore, when welding operations, it is necessary to wear protective glasses to avoid eye damage.
