A high-definition polarizer is a higher-definition polarizer used to eliminate and filter out direct rays in a beam of light. This way, the dazzling light passing through the polarizer will not be so dazzling, and the field of view will be clearer and more natural.

The biggest difference between polarized sunglasses and regular sunglasses is their handling of reflected light. People often experience various types of sudden reflections in their daily lives, which brings a lot of inconveniences. The polarized sunglasses filter out this reflected glare, which can play a role in preventing dizziness. In addition, during summer travel, they can also make the field of view clearer and reduce visual fatigue.

Sunglasses do not polarize and generally have only two main functions: shading and UV filtering, and their UV filtering efficiency is low. The partial sunglasses can filter out this type of light, only absorb the reflected light of the object itself, truly present the object itself, make the vision clearer, and thus reduce visual fatigue.

The principle of a polarizer is to allow only one vibration direction of the light wave to pass through (light is a transverse wave) to absorb light waves from other propagation directions, thereby reducing light intensity. Therefore, when two polarizers overlap, they present different angles, and the light passing through the two polarizers is also different. The polarizing test film adopts a special printing method that utilizes the polarizing principle to enable the polarizing mirror to see the parallel light emitted from the internal image, so as to see the hidden image (note, this is not perspective!), which is actually just the embedding of the parallel light image.
