What are the use scenarios of laser safety glasses?

Because laser technology is becoming more and more commonly used, laser goggles, as key equipment to protect the eyes from laser radiation damage, play an indispensable role in many fields. Now let's talk in detail about the specific use scenarios and important significance of laser goggles in the fields of industrial manufacturing and medical fields.

1. Industrial manufacturing field

① Laser cutting

Laser cutting is an important technical means in modern industrial processing. In this process, a high-power laser beam is precisely focused on the surface of the material, and its extremely high energy density causes the material to quickly absorb heat and reach the temperature of melting or vaporization, thereby realizing the cutting and separation of the material. However, this process is accompanied by complex physical phenomena and will produce strong laser radiation. The plasma formed during the cutting process will release harmful radiation of multiple wavelengths including visible light, ultraviolet light and infrared light. These radiations are not only high in intensity, but also cover a spectral range that is harmful to the eyes to varying degrees. For example, ultraviolet rays may cause inflammation of the cornea and conjunctiva, infrared rays may cause thermal damage to the retina, and high-intensity irradiation of visible light may also cause discomfort and potential damage to the eyes.

Laser safety glasses play a vital protective role in this scenario. It can effectively filter and absorb these harmful laser radiations through special optical design and material selection. The lenses of laser goggles of LaserPair are used absorbents for a specific laser wavelength and have a high absorption rate for lasers of a specific wavelength. When the laser is irradiated on the goggles, most of the harmful radiation is blocked, thereby protecting the operator's eyes from serious injuries such as burns and retinal damage. This ensures the visual safety of operators when observing the cutting process at close range, allowing them to accurately monitor the cutting quality and progress without having to worry about the harm of laser radiation to the eyes, thereby improving work efficiency and operational safety.

② Laser welding

Laser welding uses a high-energy-density laser beam as a heat source to quickly heat the joints of the materials to a molten state, so that the materials fuse together to form a strong welded joint. During the welding process, in addition to the direct light of the laser itself, a strong arc of intense light is also generated. This strong arc of light contains rich spectral components and also releases a large amount of harmful radiation. The energy of laser welding is concentrated, and the intensity of light radiation is extremely high, and the potential threat to the eyes cannot be ignored. If the operator's eyes are directly exposed to this light radiation, it may cause photoelectric ophthalmia, that is, after the eyes are exposed to ultraviolet rays, the corneal epithelial cells are damaged, causing symptoms such as eye pain, tearing, and photophobia. Long-term exposure may also cause retinal burns, seriously affecting vision.

Laser goggles provide reliable eye protection for laser welding operators. It uses materials and structural designs that can effectively block welding light radiation. The lenses of the goggles can absorb most of the laser radiation and strong light arcs, reducing the light energy entering the eyes. Its protective effect has been strictly tested and verified, and can meet the protection needs of laser welding with different powers and wavelengths. Wearing laser goggles can effectively prevent operators from having eye problems such as photoelectric ophthalmia and retinal burns, and ensure their eye health during long-term welding operations. This enables operators to perform high-quality welding work under safe conditions, improving the stability and production efficiency of the welding process.

③ Laser marking

Laser marking is a technology that uses a laser beam to etch a permanent mark on the surface of an object. Although the laser power used in laser marking is relatively low compared to cutting and welding, reflected light will still be generated due to the long-term action of the laser on a small area. These reflected lights may contain the original wavelength components of the laser, or they may generate scattered light of other wavelengths due to the characteristics of the material. Long-term exposure to this reflected light may cause chronic damage to the eyes, such as macular degeneration of the retina. The macula of the retina is the area with the sharpest vision of the eye. Once damaged, it will have a serious impact on vision, such as decreased central vision and distorted vision.

Laser safety glasses are of great significance in laser marking scenarios. They can absorb these reflected lights and reduce the intensity of light entering the eyes. The design of the goggles takes into account the characteristics of laser marking operations and has targeted protection capabilities for the wavelengths of reflected light that may be generated. Laser goggles are especially indispensable in situations where high-precision marking is required and operators need to observe the marking effect for a long time. It provides operators with continuous eye protection, prevents chronic eye damage, and ensures the safety of laser marking work. At the same time, the comfort and clarity of laser goggles have also been optimized, so that operators can still clearly observe the marking process while wearing goggles, ensuring marking quality and work efficiency.

2. Medical Industry

① Laser surgery: In the field of laser surgery, such as excimer laser surgery in ophthalmology for vision correction and laser freckle removal surgery in dermatology, high-energy lasers act directly on human tissues. During surgery, the interaction between laser and tissue will produce complex physical phenomena. Lasers may scatter due to the unevenness of tissues and the refraction and reflection of laser beams in tissues. At the same time, the vaporization of tissues under the action of lasers will also produce reflected light. These scattered and reflected lasers may cause damage to the eyes of medical staff. For example, in ophthalmic surgery, if the doctor's eyes are affected by laser scattering, it may pose a potential threat to his own vision. Moreover, during surgery, medical staff need to operate at close range, and the risk of eyes being exposed to laser radiation is high.

Laser goggles provide critical eye protection for medical staff during laser surgery. It is specially designed for the laser wavelength and energy used in surgery, and can effectively block scattered and reflected lasers. The lenses of the goggles are made of high optical quality materials, which can not only ensure good visual clarity, not affect the observation of surgical operations, but also provide reliable protection performance. Wearing laser goggles can prevent medical staff's eyes from being injured by lasers, ensure the visual safety of doctors and nurses during the operation, and ensure the smooth progress of the operation. This is of great significance to improving the success rate and safety of the operation, and also protects the occupational health of medical staff.

② Operation and maintenance of laser treatment equipment: Laser treatment equipment is widely used in the medical field for the treatment and rehabilitation of various diseases, such as laser physiotherapy devices for pain relief and tissue repair, and laser beauty equipment for skin beauty. There are certain risks when operating and maintaining these devices. Laser emission may be accidentally triggered during the commissioning, calibration and maintenance of the equipment. Moreover, these devices use laser wavelengths of various types, including infrared lasers for deep tissue heating and visible light lasers for skin treatment. Lasers of different wavelengths have different mechanisms of eye damage. For example, infrared lasers may cause thermal damage to the retina, while visible light lasers may affect the cornea and lens.

Wearinglaser safety glasses is an important measure to ensure the safety of operators. Laser goggles can be selected and configured according to lasers of different wavelengths, and have targeted protection capabilities. It can effectively absorb or reflect these lasers that may be accidentally emitted to prevent the operator's eyes from being injured. Whether in daily equipment operation or during equipment maintenance and troubleshooting, laser goggles provide operators with reliable eye protection and protect them from the threats of lasers of different wavelengths. This helps ensure the normal progress of medical work, reduces medical accidents and personal injuries caused by laser injuries, and ensures the safety of medical equipment operation and maintenance.

In summary, laser goggles play a very important role in the fields of industrial manufacturing and medical care. Wearing laser goggles is not only a necessary equipment to protect our glasses, but also advocated by the entire laser industry.
