Safety
Eyewear
If your work involves hazards
from dust, flying objects, or particles that may strike you
from in front, you should be using some form of safety
glasses. Resistance to impact is the main difference
between safety glasses and regular glasses, which often look
just like them. Lens materials include polycarbonate,
plastic or glass, each of which varies in strength, impact
resistance, scratch resistance and weight. Safety
eyewear can come in stylish designs and tinting.

 What
Makes Them "Safety" Glasses?
The American National
Standards Institute (ANSI), which sets standards for
safety glasses, requires them to withstand the
impact of a quarter inch steel ball traveling 150
feet per second. You can't depend on your
prescription glasses for this kind of protection.
Frames stamped with the imprint "Z87" meet stringent
standards for strength and heat resistance.
 It
is important to remember that standard safety
glasses protect against impact from the front only.
For this reason the some safety glasses have side
shields to provide limited protection from the sides
for tasks such as sanding, buffing, and drill press
work. When hazards come from above and below
as well as the side goggles can be used instead of
glasses or a face shield can be worn over the safety
glasses. |
 Face
Shields
Face shields worn alone
are not considered protective eyewear. They are designed
to provide general protection to the face and the front of
the neck. Face shields do not fully enclose the eyes,
and are to be used in conjunction with primary eye
protectors such as safety glasses or goggles. Face shields
are available with crown protectors to protect the front
part of the head, or chin protectors.
 Care
and Use
Your safety glasses are
designed to protect you from accidental injury. They will
not withstand repeated impact or abuse, however. Inspect
them regularly for scratches, cracks or other wear and
replace them if the are scratched, bent or uncomfortable.
Scratches not only interfere with your ability to see what
you're doing - a hazard in itself; they can also weaken the
structure of the lens and its resistance to impact.
Recommendation
2 pairs or glasses and
goggles, 1 face shield. A backup of the glasses and
goggles is good because we always seem to lose them.
