Polarizers belong to sunglasses, but polarizers are relatively high-end sunglasses. Polarizers have the effect that ordinary sunglasses do not have, that is, they can effectively block and filter out various polarized light that is harmful to the eyes.


Polarized light is the irregular reflected light produced when light passes through uneven roads, water surfaces, etc. It is also called glare. When these light rays directly irradiate people's eyes, they can cause discomfort and fatigue in the eyes, making it difficult to see the object for a long time, and the clarity of the seen objects is obviously not enough.


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.

The main uses of polarizers
The main purpose of polarizers is to protect the eyes from damage under specific conditions. However, for those who generally do not have high requirements, using regular sunglasses is sufficient. If you need to drive, it's best to wear polarized sunglasses while driving. Because driving often encounters various types of glare, polarized sunglasses can block part of the glare, and at the same time filter out the strong light reflected from the ground or the opposite car body, so that the field of vision is clearer, reducing visual fatigue, which is beneficial Drive safely.
In addition, wearing polarized lenses is also more suitable for outdoor activities such as fishing, skiing, and vacations.

Distinguishing between polarizers and regular sunglasses
In fact, the method of distinguishing between polarizers and sunglasses is simple. As long as the two polarizing lenses are stacked vertically, if they are opaque, it indicates that they are polarizing lenses. Because the special design of polarizing lenses only allows parallel light to pass through them, when the two lenses are stacked vertically, most of the light is blocked.
In addition, you can also go to the sun for a specific experience, and under sunlight, polarizers will be much more comfortable than regular sunglasses.
