Australians suffer around 50 000 eye injuries every year even though many of them were wearing eye protection at the time of their injury. Impact resistant safety glasses can protect users from significant damage but it’s wise to consider how much impact protection you may need in your safety glasses.
Safety eyewear is often incorrectly fitted, is not rated appropriately for the task or does not provide adequate protection, according to a 2008 report from Safe Work Australia (SWA).
Ordinary eyewear such as prescription glasses, sunglasses or contact lenses do not offer appropriate eye protection and can actually increase the severity of eye injuries in the event of an incident.
Eye injuries can lead to permanent vision loss, contributing to depression and negatively affect work and social relationships, as described in a Comcare “Eye Health in the Workplace” guide.

The most dangerous injuries for the eyes are construction, mining, agriculture, forestry and fishing industries, in which 60 per cent of all eye injuries in Australia occur.
It is therefore critical you have the appropriate eye protection. That means knowing when to use medium, high or extra high impact rated eye protection and when to use safety glasses, safety goggles, face shields or a combination of these.
Choosing your safety glasses impact rating
Eye protection impact ratings are determined by the PPE’s ability to withstand an impact from a specifically-weighted ball without cracking, detaching or dislodging, breaking or coming into contact with the eye or the head.
|IMPACT RATING||RATING REQUIREMENT||SUITABLE TASKS|
|Low Impact:||Can withstand impact from an object moving at 12 metres per second.||Chipping, riveting, spalling, hammering and managing a strap under tension. Choose safety glasses with a Standards mark.|
|Medium Impact:||Can withstand impact from an object moving up to 45 metres per second.||Scaling, grinding and machining metals, some woodworking tasks, stone dressing, wire handling and brick cutting. Choose safety glasses with a Standards mark ‘I or F’.|
|High Impact (visor only)||Can withstand impact from an object moving up to 120 metres per second.||Metal chipping, hydraulic nailing or any mechanical procedure involving high velocity machinery.|
|Extra High Impact (visor only)||Can withstand impact from an object moving up to 190 metres per second.||Any mechanical procedure involving very high velocity machinery.|
The difference between glasses, goggles and face shields:
While impact resistance is critical you should also consider whether you need safety glasses, safety goggles, a face shield, or a combination of these.
Safety glasses allow air in and around the eye area while safety goggles fit tight against the face, offering protection against dust and splashes. Face shields provide further protection and can also be worn over spectacles or goggles.
Also consider the type of lense, the shape of your head and if anti-fog lenses for use in humid conditions are required.
Safety glasses impact resistance Certification
All pro Safety Gear protective eyewear is rated medium impact or higher, has polycarbonate lenses; 99.9% UV protection and is certified to AS/NZS1337.1:2010 Standards.
That Certification means you have quality assurance that the impact resistant safety glasses will perform as stated.
Check your safety eyewear to see if it has the Australian Standards logo which indicates they conform to tests for impact resistance.
