Protective glasses are glasses that play a special role. They are used in different occasions and need different glasses. They are divided into safety glasses and protective masks, which need to be worn for a long time at work.
There are many kinds of protective glasses, including dust-proof glasses, impact proof glasses, chemical proof glasses and light radiation proof glasses.
Classification and corresponding use:
Impact proof glasses: mainly used for mechanical damage to eyes caused by metal or gravel debris. Spectacle lenses and frames shall be strong in structure and resistant to impact.
Chemical resistant glasses: mainly used to prevent the chemical damage of irritating or corrosive solution to the eyes. The lenses are acid-base and corrosion-resistant.
Dust-proof glasses: dust-proof glasses are used in dusty environment, and generally the requirements for lens fastness are not high.
Anti radiation glasses: workers engaged in electric welding, gas welding, steel making and glass blowing should wear anti arc radiation glasses. The color of the lenses can be dark or light, which should be selected according to the working environment.
Anti radiation protective glasses are used to protect the eyes from excessive ultraviolet radiation. The lens is made of special glass that can reflect or absorb radiation, but can pass through certain visible light. Each type of protective glasses is made of different materials. For example, anti laser glasses have high requirements for lenses.
