TYPE OF UV RAYS There are two types of UV rays: UV-A and UV-B. Over time, the effects of UV rays may cause a number of eye problems.
UV-A
Can hurt your central vision. It can damage the macula, a part of the retina at the back of your eye.
EYE PROTECTION STANDARD The Australian Eye Protection Standard considers the risks of injury and provides guidelines to mitigate against them. Selecting the wrong type of safety glasses or goggles in handling the application hazard can have serious consequences. It is important to consider possible risks including velocity, size and the nature of the hazard when evaluating the right eyewear. The Standards for protective eyewear provides an excellent source of information and assistance. AS/NZS 1336:1997 RECOMMENDED PRACTICES FOR OCCUPATIONAL EYE PROTECTION This Standard sets out recommended practices for the protection of the eyes of persons at work, against hazards such as flying particles, dust, splashing materials and molten metals, harmful gases, vapours and aerosols, high-intensity radiation generated during welding operations and furnace work. Guidance is given on the selection of eye protectors appropriate to the use of particular lasers. Additional guidance is provided for manufacturers and dispensers of prescription lenses on the requirements for production of prescription personal eye protectors. AS/NZS 1337.1:2010 PERSONAL EYE PROTECTION – Eye and face protectors for occupational applications Wear proper eye protection and hats to block the UV rays. To provide adequate protection for your eyes, eyewear should: • Block out 99 to 100 percent of both UV-A and UV-B radiation • Screen out 75 to 90 percent of visible light • Be perfectly matched in colour and free of distortion and imperfection.
UV-B
The front part of your eye (the cornea and the lens) absorbs most UV-B rays, but these rays may cause even more damage to your eyes than UV-A rays.
This Standard specifies minimum requirements for non-prescription eye and face protectors and associated oculars. They are designed to provide protection for the eyes and faces of persons against common occupational hazards such as flying particles and fragments, dusts, splashing materials and molten metals, harmful gases, vapours and aerosols. Requirements for optical qualities and low, medium, high and very high impact resistance are given and appendices describing appropriate test methods are included in this Standard. Requirements for prescription-eye protectors against low and medium impact are given in AS/NZS 1337.6. Requirements for eye protectors against laser radiation are given in AS/NZS 1337, Parts 4 and 5. The aim of this Standard is to assist in the provision of safe, efficient and comfortable vision in the occupational situation, including consideration of the need for protection against sun glare and optical radiation in the natural environment. The Standard does not apply to filter oculars for protection against optical radiations generated by industrial processes, which are dealt with in AS/NZS 1338.
