A good pair of sunglasses protect your eyes from damage caused by the sun that could
- cause cataracts
- increase your risk of macula degeneration
- cause photokeratitis, which can cause blotchy vision or temporary blindness
- eye cancer
1. Polarised glasses offer glare protection
Put on your sunglasses and rotate your phone while looking at the screen. If your phone turns completely black, your sunglasses are polarised.
2. Larger frames also offer protection
Sunglasses that wrap around the side of your face reduce sunlight reaching your eyes.
3. Anti-glare coating on the back of the lens
This stops glare reflecting into your eye and is a good option to have applied to your sunglasses if you spend a lot of time outside or are sensitive to light. Usually only glasses ordered from an optometrist will have this protection.
4. Prescription sunglasses provide clear protected vision
Your sunglasses can have your individual prescription so you can be protected from the sun and still see clearly in the distance and up close without needing to change glasses.
5. Cancer Council recommended
The Cancer Council recommends that your sunglasses are Category 3 or higher for maximum protection.
