You want to buy new pairs of sunglasses?

Many people wait for the first bright, sunny day to pick up a new pair of sunglasses. But leaving eye protection to the last second can often result in buying cheap, flimsy frames. And while the sticker stuck to the lenses may claim to have 100% UV protection, these off-the-rack sunnies may be doing more damage than nothing at all. Once you decide that you want to spend a little more to get a better block between you and harmful UV rays, however, the choices can seem confusing and overwhelming. Particularly when it comes to polarized lenses.

So we’ve put together this quick and handy guide on polarized lenses to help you figure out if you need the added boost from this particular lens technology.

Here’s what this article covers:

 

What are the benefits of polarized lenses?

Let’s start with the basics.

While all tinted lenses reduce brightness, polarized lenses are particularly useful for limiting glare. Glare is what happens when the sun hits a flat surface and the light is reflected back into your eye at a greater magnitude.

Harsh glare also has some harmful impacts on your immediate vision — from reduced depth and colour perception, all the way to temporary blindness. You’re most likely to encounter glare on a bright day on the ski slopes, as water and snow are particularly reflective.

Glare Reduction for a Clearer Vision

Regular sunglasses mean that while your eyes are shaded from overall light, they aren’t protected from this direct reflective glare. Polarized sunglasses specifically filter much of this glare, giving you a clearer vision with less eye strain.

How Do Polarized Lenses Reduce Glare?

Polarized sunglasses lenses contain a chemical filter that absorbs horizontal light waves (reflections), while allowing the vertical waves to pass through (direct light).  By removing the horizontally reflected light, the polarized chemical filter eliminates any glare but preserves colour, depth, and clarity.

Buying polarized lenses guarantees the highest quality protection for your eyes and you have to consider several aspects in order to choose them wisely.

How to Choose the Right Pair of Polarized Sunglasses?

Choosing the right lenses requires care and precision. You want to find a pair that protects your eyes properly and fits your needs. Here are 4 aspects to be considered when you’re choosing sunglasses.

1. Anti-Uv Treatment

UV rays protection is by far the most important aspect of your sunglasses. Those invisible waves emitted by light are harmful to your eyes. Containing more energy than visible rays, the absorption of UV can affect the regeneration of your eyes and be damaging in the long term. And be aware that they run all year long!

Do you want to buy sunglasses that guarantee effective eye protection? Polarized lenses offer 100% UV protection as they are c treated for that purpose.

2. Frame Shape

You are an outdoor explorer? You want to have the most convenient sunglasses with an effective vision and protection. Look for the sunglasses whose frame will totally cover your eyes as rays come from the sides too!

Find polarized sunglasses that cover your eyes properly. No need to copy Lady Gaga (well, except if you want to!), many polarized glasses have a discrete look and an effective eye envelope.

3. Prescription Sunglasses

Do you want to have your sunglasses adapted to your vision? No worries, you can easily get prescription sunglasses with polarized lenses. The best of both worlds, just for you!  

4. Lens Colour

Various tints are offered and all have a different visual effect. The preferences differ from a person to another and depend on the activity. Some glass tints with brighter colours are better to play golf, while others maintain colours equally. You adapt your polarized sunglasses to your lifestyle!

When should I wear polarized sunglasses?

You can wear polarized lenses at any time, but they’re particularly useful while on sand, surf, and snow — from the lake to the slopes, water makes the likelihood of glare all the greater. And you’re much more likely to miss out on great views.

Polarized eyewear is also well-loved in the outdoor sports world, allowing athletes like cyclists, runners, rowers, golfers, and more to see their path with added clarity and protection.

When should I not wear polarized lenses?

We assume most people aren’t wearing their sunglasses inside, but it should be noted that polarized lenses often black out or severely reduce the visibility of liquid crystal display (LCD) screens — which includes your smartphone, tablet, laptop, and most other electronic screen-based devices.
