Eye goggles are a flat plate of hard, clear plastic held in a flexible frame of soft plastic with an elastic strap connected at two points. The flexible plastic frame is normally translucent and may have ventilation holes. Most safety glasses are large enough to enclose regular eyeglasses.
Found near machinery and hazardous liquids. Available for hire in tool hire shops and sold by hardware stores and home centers. Distinguish them from swimming goggles, which neither fit over regular glasses nor are shatterproof.
Shielding the eyes from injury from splashing fluids and flying debris that result from using tools and machines. Ordinary hammering on another tool or on any piece of metal is liable to throw debris, and is not safe without eye protection.
Photons pass easily through transparent plastic while flying debris hits the plastic and bounces off.
Prescription eyeglasses can be worn as safety glasses if made of shatterproof plastic and equipped with side shields; note, however, that eyeglasses are no help against splashed fluids. Some people prefer a full-face safety shield on an adjustable headband. In the absence of safety glasses, you could do worse than wearing ski goggles.
How to Use:
1. Choose safety glasses that fit your face (and over your eyeglasses, if needed) as well as the job.
2. Before beginning work that might throw fluids or debris into the air, put safety glasses on. Adjust them for comfort and make sure they’ll stay put while your hands and attention are directed elsewhere.
3. When you are done, remove the safety glasses, wash them, and put them away for next time.
If your safety glasses fog up, try a full-face shield.
One pair of safety glasses that fit and are comfortable enough to be worn even when you don’t think they’re strictly necessary.
