Types of safety glasses
Safety glasses can vary in the levels of protection they provide.
Safety glasses are made with shatter-resistant plastic lenses. The main difference between safety glasses and regular glasses is their resistance to impact.
Safety glasses are high quality glasses which are light and comfortable with very little or no optical distortion. Contact lenses may be worn with safety glasses.
Types of safety glasses and goggles include (with or without side shields):
* Goggles for chemical splash
* Goggles for dust or materials such as flying pieces of metal or other solid
objects
* Face shields (worn with goggles to prevent chemicals or solid particles from
getting into the eyes)
Goggles are also useful when hazards come from above and below as well as the side, such as in lathe work and other high speed cutting and shaping operations.
Goggles for splash or fine dust protection should have indirect venting. Direct venting goggles should be used for less fogging when working with large particles.
Goggles are usually made with wide contact between the goggle and the face to provide for a comfortable fit.
The goggle strap should be adjustable. Food and chemical industries require a strap that does not absorb bacteria or chemicals.
