Eyes can be permanently damaged by the sun’s UV radiation,
Eyes can be permanently damaged by the sun’s UV radiation, so it is preferable that sunglasses:
- are a 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.
- have polarised lenses to reduce glare and make it easier to see on glarey days.
- The darkness of the lens shouldn’t be used to gauge protection from UVR. Some clear lenses may provide maximum protection from UVR, although a tint is desirable to reduce glare.
- The price of sunglasses doesn’t have any relationship to protection from UVR. Low cost sunglasses that comply with the sunglass standard can provide excellent protection from UVR.
