With the vigorous development of laser industry, more and more people begin to pay attention to the R& D, production and application of laser. Among them, what impact will laser have on human body?

The impact of laser on human body mainly include skin damage and eye damage.
Damage to human skin
When the high-power laser irradiates the skin, it will cause damage to the skin tissue. The damage level of laser to skin is mainly affected by laser irradiation amount, laser wavelength, skin color and tissue moisture. In serious cases, there will be erythema, blister, carbonization, boiling, combustion and even vaporization. Therefore, it is not difficult for us to know that the damage of laser to human skin is mainly due to the thermal effect produced by laser.
Damage to eyes

When laser does harm to human body, its harm to eyes is the most serious.
The damage of far-infrared laser to eyes is mainly aimed at the cornea, while ultraviolet laser is mainly absorbed by crystals. After corneal injury, it will cause keratitis and conjunctivitis, and the injured will also have symptoms such as fear of light, tears, decreased vision, congestion and so on. When the crystal is damaged, there will be crystal turbidity.
It is essential to pay attention to the safety of eye protection when wearing laser goggles. Therefore, we must pay great attention to the safety of eye protection when wearing laser goggles.
Before using the laser for operation, check whether there is light leakage, and seal the position that may leak light; The working environment shall have sufficient daylighting, and the surrounding protective structure made of light absorbing materials shall be selected; When working with lasers, individuals should first check whether goggles and protective uniforms are intact.
