What kind of protection does protective glasses include
Many people think that protective glasses are only one type of laser-proof glasses, but in fact there are many types of protective glasses. Even laser-proof glasses are just one of the types of anti-arc radiation glasses. There are a lot of classifications under its big category. Understanding the classification can better help us choose the most suitable protective glasses.
Shockproof glasses: mainly used to prevent mechanical damage to the eyes such as metal or sand debris. Spectacle lenses and frames should be strong and resistant to shock. Covering edges are provided around the frame, and there should be ventilation holes. Protective lenses can be made of tempered glass, glued glass or copper wire mesh protective glasses. Suitable for turning, grinding, milling and other occupations.
Chemical resistant glasses: mainly used to protect the eyes from chemical damage caused by irritating or corrosive solutions. The lenses are resistant to acid and alkali and corrosion. Ordinary flat lens can be used. The frame should be covered to prevent the solution from splashing. Usually used in laboratories, hospitals and other places, general medical glasses can be used.
Arc-proof radiation glasses: Workers engaged in electric welding, gas welding, steelmaking, and glass blowing should wear arc-proof radiation glasses. The color of the lenses is dark and light, which should be selected according to the working environment. Can absorb visible light and infrared rays to prevent damage to the glasses.
Anti-radiation glasses: used to protect the eyes from radiation such as excessive ultraviolet rays. The optical glass is made of special materials that can reflect or absorb radiation, but can transmit certain visible light. Each type of protective glasses is made of different materials, such as laser-proof glasses, which have quite high requirements for lenses.
