Choosing Sunglasses
Ensure the sunglasses you select meet the following essential criteria:
• They are identified as general or specific purpose sunglasses (and not fashion).
• Their label indicates they comply with the requirements of AS 1067 or are rated EPF 10.
• The lenses absorb at least 95% of UV radiation (or transmit less than 5% UVR).
• If the sunglasses are to be used while driving, then colours should still be easily recognized when viewed through the lens.
Sunglasses are an optical appliance and should be purchased from an eyecare professional. Your ProVision Optometrist has access to manufacturers’ technical information and can provide you with all the advice you need to make the right decision. Only sunglasses meeting the Australian Standards are available from your ProVision Optometrist.
If required, your prescription can be applied to your new sunglasses and they will be adjusted to provide an exact fit, ensuring your comfort and the best possible protection from the sun’s rays.

Why do I need to wear sunglasses?
More than just a fashion accessory, sunglasses should protect your eyes from damaging ultra-violet rays, glare and the heat of the sun. Your prescription can also be applied to sunglasses ensuring you achieve optimal vision.• Ultra-violet (UV) rays contribute to conditions such as cataracts and pterygiums so it is essential to wear sunglasses when outdoors which protect against these harmful rays.
• Sunglasses have tinted lenses to block some visible light so as to enhance your visual performance. Typically sunglasses will block at least 65% of visible light. The level or colour of the tint is not an indication of the level of UV protection however. • Glare is created by reflected light and can reduce our ability to see clearly and comfortably. Sunglasses can help to reduce the effects of glare and eliminate the need to squint. • In addition to ultra-violet rays, the sun also emits infrared (IR) rays which generate heat and can make your eyes feel hot and dry. Sunglasses should block 75-100% of IR rays for optimal eye comfort. |
