Category level of protection
When choosing your sunglasses make sure that they provide UV protection and reduce glare from the sun.
Check that the glasses are labelled as either 'sunglasses' or as 'special purpose sunglasses' and not as 'fashion spectacles'.
Sunglasses must have a label that states that they comply with the requirements of the Australian/New Zealand Standard for Sunglasses and Fashion Spectacles, AS/NZS 1067.
Sunglasses fall into five different categories.
Lens category 0:
These are fashion glasses - not sunglasses. They have a very low ability to reduce sun glare and provide limited, or no, UV protection.
Lens category 1:
Like category 0 lenses, these are not sunglasses. They provide very limited glare and UV protection. Category 1 lenses are not suitable for use when driving at night.
Lens category 2:
Sunglasses in this category provide a medium level of sun glare reduction and good UV protection. Many sunglasses are rated as category 2.
Lens category 3:
These sunglasses provide a high level of sun glare reduction and good UV protection. This is the type of sunglasses that your optometrist will prescribe for you.
Lens category 4:
Special purpose sunglasses that provide a very high level of sun glare reduction and good UV protection. Lens category 4 sunglasses must not be used when driving at any time.
