Notes
These laser safety goggles have no protection function against the 450-800 nm visible light (red, blue, green, yellow). It is mainly used for infrared light protection.

The dangers of laser
The laser comes with directional light emission, high brightness, pure color, and high energy density. Because the human eyes have focusing effects, the energy of laser irradiation per unit area of the retina is nearly 100,000 times higher than that of the cornea. Therefore, even a small amount of laser irradiation can cause serious damage to the retina or cornea!
