Polarised sunglasses are perfect for people who spend a lot of time outdoors. They can help improve your vision by reducing glare and eye strain.
Anyone who is sensitive to light will benefit from polarised lenses, including those recovering from cataract surgery.
Sunlight scatters in all directions, but when it hits a flat surface like water the light is reflected in a horizontal direction creating glare. Polarised lenses have a special filter which blocks horizontal light meaning glare is significantly reduced.
Polarised glasses can enhance your vision and reduce eye strain, and as long as they comply with Australian Standards they also provide protection from harmful UV rays.
When you’re in the market for new sunglasses it’s important to make sure they provide adequate UV protection.
The sun can be just as harmful to your eyes as your skin. Long term exposure to UV rays can cause a range of eye diseases including cataracts. Children’s eyes are particularly sensitive, as the sun’s rays penetrate deeper into the eye, which may result in damage to the retina or lens.
The key things to look for when buying sunglasses are:
• Make sure sunglasses have Australian Standards Compliant labeling
• If glasses are marked 'fashion spectacles' they provide little or no absorption of UV rays
• Choose category 2 and 3 sunglasses for everyday use
• Category 4 sunglasses provide a high level of UV protection, but they are very dark and should not be used for driving
The shape of the frame can also help protect your eyes and the delicate skin around the eyes from premature aging. Oversized glasses and wrap around frames offer an extra level of protection from the sun’s rays.
