Eye
Injuries
Many
studies have shown that approx 70% of eye injuries
result from flying or falling objects. Two thirds
of these objects were as small as a pin head, most
particles moving faster than a hand thrown object.
Contact
with chemicals causes approx 20% of injuries.
Other
accidents were caused by objects swinging from a
fixed or attached position, like tree limbs,
ropes, chains, or tools which were pulled into the
eye while the worker was using them.
40%
of injuries studied occurred among mechanics,
repairers, carpenters, and plumbers. Over a third
of the injured workers were assemblers, sanders,
and grinding machine operators. Labourers suffered
about 20% of the eye injuries.

Impact
resistance for mechanical strength F is tested by firing
a 6mm steel ball weighing 0.86g travelling at 45 m/s.
Mechanical
strength S measured by dropping a 4.3g 22mm steel
ball at only 12 m/s.
Grade
F is suited
for tasks like drilling, sawing, grinding, hammering or
risk from any process which could emit particles whose
energy equates to the test specifications above.
Grade
S can be
used in hazardous areas where there is risk of small
flying particles from other workers or processes in the
vicinity but where the wearer is not close to the
source of the hazard.
All
our lenses are Optical Class 1.
Goggles
Housing
has higher
impact resistance with greater protection from hazardous
liquids, dust and gases. Goggles provide the minimum
protection for mechanical strength
B (6mm 0.86g steel ball at 120m/s)
Face shields
Housing
has even higher impact resistance but offering head protection
and prevents damage to soft tissues of the face. Often
safety spectacles are worn beneath in addition.
Face shields
provide protection for
mechanical strength A
(6mm 0.86g steel ball at 190m/s)
