What Are Polarised Sunglasses?
Australia's sunny climate makes sunglasses a daily essential for many. But not all sunglasses are created equal. If you've ever been blinded by the intense reflection off water, roads, or glass, you’ve encountered glare. This is where polarised sunglasses come into their own. But what exactly are they, and how do they differ from regular sunglasses?
In this blog, we'll explain what polarised sunglasses are, how they work, their benefits, and when to wear them. We’ll also compare polarised vs normal sunglasses to help you make the right choice for your lifestyle.
How Polarised Sunglasses Work to Protect Your Eyes
Polarised sunglasses are lenses designed with a special filter that blocks glare caused by reflected light. Unlike ordinary lenses, which merely darken your field of view, polarised lenses specifically target light that bounces off flat surfaces such as water, roads, snow, and car bonnets.
This targeted filtering enhances visual clarity, reduces eye strain, and provides a more comfortable viewing experience in bright environments. For outdoor lovers or frequent drivers, they are a game-changer.
How Do Polarised Lenses Work?
To understand how polarised sunglasses function, it helps to look at how light behaves. Sunlight travels in all directions, but when it hits reflective surfaces, it becomes concentrated and moves horizontally. This horizontal light creates glare, which can overwhelm your eyes and obscure vision.
The filter within polarised lenses is vertically aligned, meaning it allows vertical light to pass through while blocking most of the horizontal glare. The result is a significantly clearer and more natural view.
Benefits of Wearing Polarised Sunglasses
Improved Visual Comfort
By cutting down glare, polarised sunglasses reduce squinting and eye fatigue. This makes them ideal for activities like driving, boating, fishing, or even walking along a sunlit pavement.
Better Clarity and Contrast
Polarised lenses enhance contrast and detail, making colours appear more vivid and your surroundings sharper. This benefit is particularly noticeable when near water or snow.
Safer Driving Conditions
Drivers are regularly faced with sunlight bouncing off windscreens, car bonnets, and wet roads. Polarised sunglasses improve road visibility by minimising this blinding glare, which can make a big difference in reaction time and road safety.
Polarised vs Normal Sunglasses
At first glance, normal sunglasses and polarised sunglasses may appear similar, but their performance differs significantly.
When comparing polarised vs normal sunglasses, polarised lenses clearly stand out for anyone who spends time outdoors in reflective environments. However, they may not always be the best option in every situation.
When Should You Wear Polarised Sunglasses?
Polarised lenses are beneficial for many everyday and recreational activities, especially in Australia where sunlight is intense and glare is common.
Ideal situations include:
Driving during the day
Fishing or boating
Spending time at the beach or by a pool
Skiing or snowboarding
Hiking or cycling on sunny days
Wearing polarised sunglasses during these activities can protect your eyes while significantly improving your vision.
When Polarised Sunglasses Might Not Be Suitable
There are a few scenarios where polarised lenses are not the best option. For instance, if you’re using devices with LCD screens such as GPS units or some smartphones, polarised lenses may make the screen appear distorted or overly dark.
Similarly, pilots and skiers sometimes avoid polarised sunglasses because they can interfere with the ability to see instrument panels or patches of ice, respectively.
That said, for most everyday users in Australia, the benefits of polarised sunglasses far outweigh the downsides.
Choosing the Right Pair of Polarised Sunglasses
When selecting polarised sunglasses, consider the following factors:
1. Fit and Comfort
Make sure the frames fit snugly on your face without pinching. For active wearers, wraparound styles can provide added stability.
2. Lens Colour and Tint
Grey lenses offer neutral colour perception, while brown lenses enhance contrast. Consider your activities and preferences when choosing a tint.
3. Prescription Options
