What type of sunglasses are recommended for working in the sun?
Eyes can be permanently damaged by the sun’s UV radiation, so it is preferable that sunglasses:
- be close fitting, wraparound style
- meet the Australian Standard (AS/NZS1067: 2003 – category 2, 3 or 4 ) and are safe for driving (this information is contained on the swing tag when purchased)
- have an eye protection factor (EPF) 10. Safety glasses that meet AS/NZS1337 still provide sun protection
- have polarised lenses to reduce glare and make it easier to see on sunny days.
The darkness of the lens should not be used to gauge protection from UVR. Some clear lenses may provide maximum protection from UVR, although a tint is desirable to reduce glare.
It is important to note that the price of sunglasses does not have any relationship to protection from UVR. Low cost sunglasses that comply with the sunglass standard may also provide excellent protection fron UVR.
