Polarised vs Non-Polarised Sunglasses - What's the Difference?

Polarised vs Non-Polarised Sunglasses - What's the Difference?
When the summer finally arrives it's important to get your hands on a quality pair of sunglasses. Although there are a lot of cheap accessories out there, you may be thinking of investing in a pair of polarised shades. Here's all you need to know about the difference.  Read more Men’s Style Guide features and check out our Store. shopthelook Let's be honest, we all feel 100% cooler and ten times more attractive when donning our favourite pair of shades, but the real purpose of wearing sunglasses can often be overlooked. Our eyesight is something we take for granted on a daily basis, but the safety of our eyes is extremely important; not only in the summer months, but all year round When it comes to sunglasses you're probably one of two types of people; the cheap and cheerful type, or the expensive taste wins the race kind. If like many, you are option number one, you most likely buy numerous pairs of sunglasses each year due to the lower prices you spend, and you're probably kitted out in the latest eyewear trends as you don't have to play it safe if you're not spending hundreds of pounds. If though, you're in to your designer brands or you take the protection of your eyeballs very seriously, then you are no doubt comfortable spending a pretty penny for the best, but 'forever' sort of pair.

Polarised Sunglasses

What Does Polarised Mean?

Polarise: restrict the vibrations of (a transverse wave, especially light) wholly or partially to one direction. The sun light reflected by any surface, for example while driving, walking on the beach, or skiing on the mountains, is the polarised light.

How Do Polarised Sunglasses Work?

What are polarised sunglasses? So here's the science bit: Visible light waves from the sun reflect in all different directions. When this sunlight reflects off a horizontal surface such as a road or water, the rays become concentrated horizontally, causing glare. Polarised lenses have a built-in laminated filter which let's only vertical light rays through and almost completely blocks out horizontal ones. This in turn eliminates glare, and is most noticeable when on or near water, such as when sailing or fishing, as there is a drastic reduction in the brightness of shiny surfaces. Polarised sunglasses are also amazing for reduced eye strain and great comfort.

Non-Polarised Sunglasses

We're not saying that non-polarised sunglasses don't protect your eyes; they definitely do. Non-polarised lenses have a dark shade and reduce the intensity of light, however, unlike polarised lenses, they cannot counter the effects of horizontal rays. These lenses do not take into account the direction in which light is coming. toppicks

What's the Difference Between Polarised and Non-Polarised Sunglasses?

The argument of polarised vs non-polarised lenses is largely dependent on when you will be wearing them and what you will be doing at the time. Though polarised sunglasses improve comfort and visibility, you will encounter some instances when these lenses may not be advisable. Although often thought of as a great aide to any kind of winter sport, there is a slight exception when it comes to downhill skiing, as you don't want to block the light that reflects off icy patches because this alerts skiers to hazards they are approaching.

In addition, driving is another area where polarised lenses may reduce the visibility of images produced by liquid crystal displays (LCDs) or light-emitting diode displays (LEDs) found on the dashboards of some cars or in other places such as the digital screens on Sat Navs. In the same way, polarised lenses may also make it difficult to see your mobile phone screen, which in this day and age is unthinkable!

However, for most other sports and activities polarised sunglasses offer some great advantages, and many polarised lenses are available in combination with other features that can enhance outdoor experiences.

  • Polarised lenses come with a heftier price tag than non-polarised sunglasses

Are Polarised Sunglasses Worth it?

If you're a keen fisherman or boater the use of polarised sunglasses is extremely beneficial as it helps to eliminate the strong glare from the surface of the water and allows you to view deeper in to the sea for fish or obstacles. Similarly, if you do a lot of driving then we would definitely say it is worth investing in a pair of sunglasses with polarised lenses as any long summer road trips will benefit by reducing your eye discomfort and fatigue. If however you don't usually take part in regular activities that would directly benefit from the use of polarised lenses, the higher expenditure might not be worth your while.

Choosing your sunglasses should come down to a few main points first and foremost; overall protection is by far the most important aspect, with quality coming a very close second. Being The Idle Man, of course we couldn't leave out the small issue of style too, so here is our pick of the best polarised sunglasses, considering all three areas of criteria. toppicks

Ray Ban Polarised Sunglasses

In 1937 the world of sunglasses was changed forever when Ray-Ban was founded. An icon of the eyewear world, there is no other more recognised brand of glasses than Ray-Ban. With that in mind, it only made sense that they would get in on the polarised action and take their brand to the next level. Ray-Ban's polarised lenses are the result of more than 70 years of innovation and research, and they block more than 99% of the reflected lights. They offer three different qualities of Polarised lenses: P, P³ and P³Plus, ranging from the simplest to the most sophisticated additional features.

Styling Your Polarised Sunglasses

Sunglasses can totally make an outfit, and leaving the house without a pair can often leave you feeling incomplete, or worse, naked. Now that the summer months are here (kind of), you want to make sure you're well equipped for the sun and looking as cool as a 'cuc'.
