Laser goggles are glasses that must be worn to protect the eyes when using lasers.
If not worn, the laser beam can cause serious damage to the eyes. When choosing laser safety glasses, one must match the wavelength and power output of the laser being used. The optical density (OD: optical density), which indicates how much light is transmitted, should also be checked to ensure that the appropriate glasses are worn for the task at hand.
Laser goggles are worn at sites where laser processing machines or laser oscillators are used.
Laser googles should be worn when using processing machines equipped with laser oscillators (welding, cutting, engraving, marking, etc.) When performing laser treatment with medical lasers or in clinics, etc. When using a laser oscillator in research, etc. Do not look directly into the laser beam even if you are wearing protective goggles. This is because the lenses used in safety goggles are designed to protect against the scattered light of the laser and not against direct irradiation.
Laser goggles use special lenses that absorb the scattered light of the laser and make certain wavelengths less transparent.
Laser light is characterized by its directionality, unity, and coherence, which means that it is color blind and has a high energy density. High-power lasers such as those used for welding are, of course, dangerous when they hit the body, but even low-power light can damage the eye due to the above characteristics.
Care must be taken because there is a risk of damage not only to the superficial layers of the eye, such as the cornea, but also to deeper areas, such as the retina and optic nerve, depending on the wavelength. Therefore, appropriate safety goggles should be selected by checking the wavelength, output, and OD value of the laser.
The higher the OD value, the safer the laser, but it also transmits less visible light, which may reduce work efficiency. It is important to select safety goggles with an appropriate OD value, taking into consideration the nature of the work.
It is important to confirm the type of laser to be used, its oscillation wavelength and output. Select lenses and filters that match the wavelength.
There are several types of laser goggles, including "goggle," "spectacle," and "front" type. Some spectacle and frontal types have side shields, while others do not.
In order to improve workability, it is recommended to select a pair with low transmittance only in the range of the laser used and high transmittance in the rest of the visible light range. Even if the OD value of laser goggles is high, be sure to select the right fit, as lenses with the wrong wavelength will not provide protection and can lead to serious accidents.
Even with laser goggles in use, laser light cannot be prevented from entering the eye directly. Note that some laser beams, such as ultraviolet and infrared wavelengths, are invisible to the eye.
Laser beams are classified according to their degree of danger.
Some laser goggles are capable of withstanding various classes of lasers, so they are safe to use when handling potentially hazardous laser beams.
