This is also true for invisible light, infrared or ultraviolet non-visible light, which is not visible to the human eye, all without sensory stimulation to the nerves of the human eye. 2. The light energy reaches a certain degree, can produce high temperature to the object, directly forms the burn to eyes, and the power of laser reaches a certain degree, can gasify the steel sheet in the twinkling of an eye, and eyes no longer say, and high temperature or temperature sharply become to the eye cell injury very big. 3. The absorption effect of some specific laser on specific materials is particularly strong, for example, near infrared laser in 1064NM band, the laser characteristic of this band is that the absorption to water is particularly strong, if directly irradiate human eyes, it will absorb the water of human eyes, and the damage to eyes is very large.
