The Difference Between Sunglasses and Polarizers

The Difference Between Sunglasses and Polarizers

To explain polarizers and sunglasses, we must first introduce some knowledge about polarizers and sunglasses. In fact, polarizers can be   regarded as a category of   sunglasses, but polarizers are a relatively high-end category of sunglasses.

Polarizers have an effect that ordinary sunglasses do not have. This effect is to effectively block and filter out various polarized light that is   harmful to the eyes.

The so-called polarized light is the irregular reflected light generated when light passes through uneven road surfaces, water surfaces, etc.,   also called glare. When these light rays directly irradiate people's eyes, they will make people's eyes feel uncomfortable and prone to fatigue,   and they cannot see things for a long time, and the clarity of the seen objects is obviously not enough.

The polarizer uses the linear molecular arrangement inside its lens to filter and eliminate all kinds of glare that damages the eyes. The light is   rearranged so that the light that hits the eyes is clearer and more natural.

1. The difference between polarizers and sunglasses

So what is the difference between polarizers and sunglasses? First of all, both polarizers and general sunglasses have the function of preventing ultraviolet rays and reducing the intensity of light, but general sunglasses do not have the function of isolating or converting polarized light.   This is the difference between polarizers and sunglasses. Therefore, general sunglasses are relatively cheaper than polarized sunglasses.

2. Main uses of polarizers

The main purpose of polarizers is to protect the eyes from damage under certain conditions. However, for people who generally do not   have high requirements, ordinary sunglasses can be used, because polarized sunglasses are relatively high-end sunglasses. Of course, if you are a car owner who needs to drive, it is better to wear polarized sunglasses when driving, because driving   often encounters various glare lights, polarized sunglasses can block part of the glare, and can also filter out the ground or The strong light   reflected from the opposite car body makes the vision clearer, reduces visual fatigue, and is conducive to safe driving.

-The viewing angle effect of polarized lenses is more natural and clear than that of sunglasses-

In addition, it is more appropriate to wear polarized glasses when doing outdoor sports such as fishing, skiing, and vacationing.

3. The difference between polarized lenses and ordinary sun lenses

In fact, the difference between polarizers and sunglasses and the way to distinguish them are relatively simple. As long as the two polarized   lenses are stacked vertically, if it is opaque, it means that it is a real polarized lens, because the special design of the polarized lens only allows   parallel light to pass through the lens, so when the two lenses are stacked vertically, most of the light will be blocked.

In addition, you can also go to the bottom of the sun to have a specific experience. Under the sun, polarized glasses are much more   comfortable than ordinary sunglasses. Of course, the difference between polarizers and sunglasses is also clearly reflected in the price. At   present, the price of general polarizers on the market is about several hundred yuan, while the price of professional outdoor polarizers ranges   from thousands to tens of thousands.
