Why are polarized sunglasses better?

The question some of you may be asking is “Why should I choose polarized sunglasses over non-polarized sunglasses?”. There are many reasons why polarized sunglasses are king. In this article, we will explain why you should (or shouldn’t) go for polarized sunglasses.

Firstly, when it comes to sunglasses, it’s not worth penny-pinching, you only have one set of eyes. Make sure the sunglasses you buy block 99 to 100 percent of both UVA and UVB rays. It should be written on the product label. If it’s not – PASS! Keep in mind that the color and degree of darkness sunglasses provide have nothing to do with the sunglasses’ ability to block UV rays. Actually, poor quality sunglasses can do more harm to your eyes, this is because they dilate your eyes allowing for more harmful UV rays to enter.

Benefits of Polarized Sunglasses:
Polarized lenses reduce glare by filtering out the reflected sunlight that bounces off surfaces like water, snow or pavement. Which means polarized sunglasses are perfect for any water activities such as fishing, or even just hanging out on the beach or a boat, they are also great for road trips or snowy hikes!

Polarized sunglasses are used to block the intense light that is reflected from flat surfaces. Polarized glasses built-in, laminated filter permits only vertical light rays to pass through and almost totally block out horizontal rays to eliminate glare. The reason for this is that polarized sunglasses are made with vertical polarization, while the light reflected by the sun on flat surfaces is horizontally polarized.

Non-polarized sunglasses can’t counter the effects of horizontal polarization. Non-polarized lenses don’t protect your eyes from the horizontal glare (light coming from different directions).

A high quality pair of sunglasses will usually include polarized lenses. A polarized lens offers the following advantages over non-polarized lenses:
- Improves visual comfort
- Improves contrast and visual clarity
- Reduces eyestrain
- Allows for true perception of colors
- Reduces reflections and eliminates glare

Fun fact:
When wearing polarized sunglasses, the sea appears more transparent!

“The polarized sunglasses used by fishermen have polarized filters with the transmission axis oriented vertically to block the light reflected by the water surface. Note that if the fisherman moves his head up or down (nodding) the line joining the temples remains horizontal and the sunglasses continue to block the glare (of course, if he leans his head to one side the filters start to point in the wrong direction). By the way, they are not only used by fishermen but in all other water-sports. They are also becoming popular with truck drivers and for general outdoor activities. The last five years have seen a jump in their sales and are the fastest growing segment in eyewear.” – Polarization.com
