The difference between Polarised vs Non-Polarised Sunglasses

Polarised and non-polarised sunglasses both serve one function–to darken a very bright day. But do you know the difference between them?

Although all our lenses offer full UVA/UVB protection, the polarised ones reduce glare, lessen reflections and the eye strain, the reflection – improving the contrast and visual comfort.

On the other hand, non-polarised lenses provide the same protection and are usually cheaper and more durable.

In this post we will highlight the biggest differences between them and how it could impact you in some occasions:

When Driving

Polarised sunglasses are a lifesaver when you're driving. That is especially true when sunlight hits at just the right angle and interferes with your vision. Polarised lenses can filter the sunlight that reflects off roads, snow, and windshields, effectively neutralising most of it. That results in a safer driving environment, one that is free from distractions and glare discomforts.

Glare is less of an issue during brighter overcast weather, so either polarised or non-polarised glasses will make do. Some people believe that non-polarised glasses are better during lower contrast of total cloud cover.

Still, it must be noted that driving with polarised sunglasses in some snowy or icy conditions is less safe compared to non-polarised sunglasses. Patches of iced snow or black ice may be harder to see when there’s no surface reflection.

The same goes for skiing and other winter activities that make it essential to see slick patches to avoid them.

When Outdoors

The special coating in polarised lenses is highly anti-reflective, so they reduce reflections, glare, and haze. At the right angle, you might see past most surface reflections or even through the water below when you’re staring at lakes or bodies of water. Therefore, polarised lenses are the better sunglasses when you’re fishing or boating with family and friends.

The anti-glare properties of polarised sunglasses make them great for scenic viewing and nature hikes. The coating generally raises contrast during the day and can make the sky appear a deeper blue.

Polarised lenses’ anti-glare and increased contract traits may also help people with light sensitivity, but the benefits may depend on the strength or darkness of the lens.
When Looking at Screens 

Digital screens can look different when viewed through polarised sunglasses. For instance, screens on your laptop, TV, or smartphone have polarised lenses that can look slightly faded or even completely dark.

But that depends on the angle you’re looking at the screen from. While that only happens when screens are rotated at unusual angles, it’s worth noting that it does not occur with non-polarised sunglasses.

So, if you’re experiencing symptoms of digital eye strain, it’s best to get non-polarised lenses. Your eye professional may suggest you wear computer glasses that block blue light to make screen time better for your eyes.


Between polarised and non-polarised sunglasses, the better one would depend on your preferences. It all comes down to how you plan to use your sunglasses, as well as any concerns you have, such as digital eye strain. Still, it’s worth noting that many people still gravitate towards polarised sunglasses because of their broader uses.
