Tips to know if a pair of glasses is polarized

Knowing whether a pair of glasses is polarized or not is very simple, but many people do not know certain... tricks to find out. This type of lenses have become very popular in recent years, and they are quite useful in a wide variety of occasions.

However, the problem is when we buy the glasses. In many cases, the seller does not specify whether the lenses are polarized, or says that they are, but in reality they are not. To avoid getting into such a mess, today we will explain how to identify polarized glasses, and we will also tell you exactly what they are for.

What are polarized glasses?

Polarized glasses are often confused with any dark glass of sunglasses, when in fact they have nothing to do with each other. In fact, the polarization of the lenses is not even related to UV protection.

It is true that sunglasses were invented to make it easier to see in environments with a lot of glare or reflective surfaces. However, there are situations where there is so much contrast that it would be impossible to see anything, even with ordinary sunglasses.

That's where polarized sunglasses come in. On their lenses there are a series of microscopic dark lines that block the incidence of light as it passes through the glass in certain directions. In this way, you can see perfectly even if there are strong flashes.

But let's not fool ourselves, the only function of polarized glasses is not to improve vision, they can also make you look amazing. If you don't believe it, we invite you to take a look at the new Prada collection of dark glasses.

When are polarized glasses useful?

The first dark glasses appeared millennia ago, but it is true that their usefulness went beyond reducing the incidence of the sun. In fact, in China they were used by judges to hide their intentions from the accused.

Nowadays, this type of goggles are useful in practically any situation where there is a strong light source. However, it is true that they can be put to better use. For example, when practicing outdoor sports, when there is a lot of light and you have particularly sensitive eyes.

It is common to see cyclists, golfers and runners wearing them, but they are especially recommended when skiing or snowboarding, as the surrounding snow is highly reflective.

They are also appropriate for regular drivers, as polarized glasses reduce the incidence of light coming from the body and reflected from other cars. They are great for combating eye fatigue on long trips, where it is crucial to have your senses working at 100%.

Finally, polarized glasses are recommended for people who spend a lot of time in front of screens. In these cases, the filter favors a sharper vision and a reduction of the contrast between the screen and the environment.

How do you know if a pair of glasses is polarized?

Now let's get to the heart of the matter: how to tell if a pair of glasses is polarized. First of all, if you have not yet purchased the glasses, you should look at the product description (in case you are buying from a website). The name of the glasses should include the letters "P", "PR" or "PL", for polarized.

On the other hand, if you already have the glasses in your hands and you don't know if they are polarized, look for a label or plate with the letter "P". In case you can't find it, there are a couple of tricks that can be implemented in almost any situation:

Look for a screen; it could be a TV, a computer or your cell phone screen. Then take your glasses and place them in front of the screen, so that the glass is parallel to the screen. Then, turn them about 90º. If they are polarized, at some point in the turn the vision should be partially or completely obstructed. You will notice how the glass darkens.

The other method to know if a pair of glasses is polarized is very similar to the previous one, only that you will replace the screen with other polarized glasses. They must be placed in the same way, facing each other, in a lighted environment, or else you won't be able to tell the difference. Rotate the glasses through 90º until the image darkens.

If this does not happen, you know your glasses are not polarized.
