If the eyes are accidentally injured by the laser, emergency measures need to be taken in time: 1. Stop work immediately and leave the site. If you are outside, cover your eyes immediately to prevent further damage. 2. Rinse the injured eye with plenty of water or normal saline as soon as possib
At present, the world's well-known laser protective glasses manufacturers mainly have the following: 1. Honeywell：Honeywell is an American multinational company specializing in the development, production and sale of industrial safety and personal protective equipment, including laser protective gla
The origin of the laser can be traced back to the early 1950s. In 1954, Charles Townes and Arthur Ritchie of Bell Laboratories in the United States invented the first laser, which used three mirrors to reflect energy back and forth, producing highly synchronized concentrated beams of light. Since
The requirements of the European Union for laser protective glasses are mainly reflected in the EN207 and EN208 standards. These two standards specify the basic requirements for laser protective glasses and the protection requirements for high-power lasers, respectively. Specifically, laser protec
The relevant requirements for laser protective glasses in the United States are mainly reflected in the standards jointly developed by the American National Standards Institute (ANSI) and the Laser Research Association (LIA). Among them, ANSI Z136.1 Laser Safety Standard and ANSI Z87.1 Personal Pro
With the rapid development and popularization of laser technology, there have been some serious laser safety accidents due to various human negligence in the history, the following are a few examples: 1. In 1980, the US military conducted a test of a laser weapon, during which a laser accidentally
The principle of laser protective glasses is to filter or absorb the incident laser beam through a special optical filter, thereby reducing the damage of the laser beam to the retina and cornea. These optical filters usually consist of one or more layers of absorbent materials, and they work by ab
The safety level of laser protective glasses can not be measured by feeling, and must be tested and certified by professional organizations. The safety level is usually measured by OD Optical Density. The higher the OD value, the stronger the protection ability of the glasses against the laser. Whe
Laser damage to the human eye is mainly due to the laser energy is too high, into the human eye will be focused to form a high energy density spot, causing retinal damage, serious may lead to blindness. Laser damage is related to its wavelength, power, duration and other factors. Eyes exposed to
