What Are Polarised Lenses and Do I Need Them?

You have plenty of decisions to make when choosing a new pair of sunglasses: frame shape, size, colour… but one of your questions will surely be whether or not to choose polarised lenses. Most of us have heard of them but not everyone knows what they do and what benefits they have. Here’s a quick rundown to help you decide.

What are polarised lenses?
Regular sunglasses shield your eyes from rays of light that come directly from the sun, but they don’t necessarily have much impact on reflected light. Light waves that bounce off reflective surfaces like the water, car hoods, and even the road, come from oblique angles, which is why the reflection can be quite intense in your eyes.

Polarised lenses work a bit like blinds, reducing these reflected rays by up to 50%. Basically they reduce brightness and blinding glare far more efficiently than traditional sunglasses.

Who can benefit from polarised lenses?
Anyone who spends a lot of time outside can benefit from polarised lenses. If you work outdoors you’ll appreciate the significant reduction in glare. But even if you just wear them for driving, they’ll help cut those reflections from other cars and shiny surfaces that can sometimes be momentarily blinding, or at least very distracting.

Paired with added 100% UV protection in your lenses, polarisation will help provide all the benefits of sunglasses, like reduced risk of cataracts and other eye diseases.

Are there any drawbacks?
Polarised lenses can interfere with how you see certain LCD screens, such as your mobile phone or an ATM screen. Some car LCD dashboards and GPS unit screens can be affected.

So, while there are many great reasons to choose polarised lenses, they’re not for everyone. Feel free to talk to us about it at your next consultation and we’ll be happy to help you make your decision.
