Do sunglasses with darker lens provide better eye protection?
Sunglasses sold in Australia must be labelled to indicate which Australian standard (AS/NZS 1067:2003) category they comply with. Look for category 2, 3 or 4. Sunglasses that meet the standard prevent at least 95% of UV reaching the eyes regardless of the ‘darkness’ or ‘tint’ of the lens. Remember, design of sunglasses is also important as close fitting, wrap around lenses stop UV entering from the sides and tops of the lenses.
