Sunglasses Lenses--Polarized and Non-polarized

Sunglasses Lenses--Polarized and Non-polarized

Sunglasses, as a common accessory in our daily lives, not only add a sense of fashion to our looks, but more importantly, they can protect our eyes from the damage of the sun. However, did you know that sunglasses also come in polarized and non-polarized varieties? Today, we’ll take a closer look at the differences between these two types of sunglasses and how to choose between them.

1. The difference between polarized and non-polarized sunglasses

First, let’s look at what polarized and non-polarized sunglasses have in common. Whether they are polarized or non-polarized sunglasses, they all have the function of preventing ultraviolet rays and reducing light intensity, and they can also provide sun protection and shading. In appearance, there is no obvious difference between the two.

Functionally, however, there are clear differences between the two. In addition to protecting against UV rays and reducing light intensity, polarized sunglasses can also block and reflect dazzling glare. This is because it filters out light entering from a certain direction, increasing the contrast between blue and white. Therefore, when you wear polarized sunglasses and look at your phone, it is normal for colors to appear. Non-polarized sunglasses can only reduce light intensity and protect against ultraviolet rays, but cannot effectively block bright reflections and glare from all directions.

2. How to distinguish polarized and non-polarized sunglasses?

So, how to tell the difference between polarized and non-polarized sunglasses? A simple method is to rotate it 90 degrees against the horizontal plane of the electronic product. If you notice a noticeable change in the color of your lenses, then these are polarized sunglasses. If there is no change in color, then they are non-polarized sunglasses.

3. How to choose sunglasses?

Now that we know the difference between polarized and non-polarized sunglasses, let’s take a look at how to choose. If you are driving or fishing outdoors, it would be better to choose polarized sunglasses. Because polarized sunglasses can block and filter reflected glare from the ground and oncoming cars, reduce eye fatigue and are beneficial to driving safety. At the same time, it can also help us block reflected glare from the water surface, giving us a clearer vision when fishing.

However, if you are just commuting or traveling on a daily basis, then choosing non-polarized sunglasses will suffice. Because the clarity of non-polarized sunglasses will be higher than that of polarized sunglasses. In addition, since the polarized fiber in the middle of polarized lenses will make the light transmittance of the lenses lower than that of non-polarized lenses, non-polarized sunglasses are more suitable for use when the light is not very strong.

Although we generally think that we only need to wear sunglasses in the summer, UV rays are actually present all year round. Therefore, whether it is winter or summer, wearing sunglasses is very necessary. In winter, sunglasses can not only protect you from the sun, but also block the wind.

Overall, whether they are polarized or non-polarized sunglasses, they can protect your eyes. Which type of sunglasses you choose mainly depends on your needs and usage situation. Polarized sunglasses are more suitable for use in situations where clear vision is required, such as driving and outdoor fishing, while non-polarized sunglasses are more suitable for daily commuting, traveling and other occasions. Therefore, when choosing sunglasses, you need to make a choice based on your actual situation.

Finally, no matter which type of sunglasses you choose, make sure it has 100% UV protection. Because the damage of ultraviolet rays to the eyes is irreversible, we must take adequate protection. Remember, protecting our eyes means protecting our health. Let us start now to choose the right sunglasses to add health and fashion to our lives!
