How Do Polarized Sunglass Lenses Work?

Ever wondered what makes polarized sunglass lenses so popular? If you’ve been pondering about the pros and cons of making this choice for your own sunglasses, the following information will come in handy and should be a great guide on how do Polarized sunglass lenses work and other related questions?

Let’s assume you don’t know anything about it. Here are the basic things you should definitely be aware of:


What are polarized lenses?

Polarized lenses look like regular lenses from a distance, but there’s something different about how they are made and how they work. In a nutshell, a polarized lens has a special layer fused within its structure. This so-called polarization layer acts as if the lens has lots of microscopic mirrors on its surface, each one angled away from the field of vision that your eye normally has.


How do polarized lenses work?

The presence of the polarization layer prevents any light ray that doesn’t fall perpendicularly on the lens to reach your eye. It reflects it further away, filtering through most of the light that would otherwise hit your visual field.

The direct effect is a reduced light intensity from all angles. In other words, polarized lenses block much of the light that comes to the lens and significantly reduce the glare of anything you’re looking at.


What do I do if I want to upgrade my sunglasses to get polarized lenses?

If you’re ready to make the change, suffices to pick a reputable seller. Pacificlenses is here to support you with any choice, offering you a wide selection of thousands of different sunglass lenses.

What are the actual benefits of wearing polarized lenses?

The key is in the glare reduction. Thanks to it, you’ll be able to wear your sunglasses for longer and spend more time in very bright environments, without dealing with the common eyestrain.

Not only it brings more visual comfort, but it can also have a direct, positive impact on people who frequently suffer from migraines.

Many of our customers happily reported a reduced headache onset once they started to wear polarized lenses.


Are there any situations when polarized lenses are not a good choice?

Most of the time, you’re only going to get benefits from wearing polarized sunglass lenses. Nevertheless, you should never forget that these lenses block the glare and the light coming from certain angles. This means that occasionally, you may not notice details that you’d otherwise see just fine when not wearing the sunglasses.

Say you’re on a ski slope or behind the wheel, tackling an icy road – parts of what’s in front of you may not appear as visually strong or bright as they are in reality.

Some differences may also occur when using an LCD display with your sunglasses on. Whether it’s the display of your computer, smartphone, or even the microwave or the car stereos, there will be some visual differences that may or may not make you feel too comfortable.

Last but not least, if you have tinted car windows with polarized films, you might also notice some kind of impact when wearing your polarized sunglasses in the car.


Can I check if my current sunglasses have polarized lenses?

One way to tell whether your sunglasses have polarized lenses or not is to simply look at the glare of water or a car window. If you can watch comfortably at glares that you can’t stand when not wearing your glasses, there’s a good chance that you have polarized lenses already.

A better way to tell is if you can remove one of the lenses from its frame, position it at 90 degrees compared to the other one, and look through both lenses at the same time. If they’re polarized, you won’t be able to see out of the lenses.

Typically, a regular lens will appear darker and show the same degree of tint anyway you look at it. But not polarized lenses! These ones will black out when positioned at certain angles.
