What Is the Difference Between Night Vision Glasses and Polarizing Glasses?

1.What is the difference between night vision glasses and polarizing glasses
1. Different principles
Polarizer is made according to the polarization principle of light, which disperses unwanted light, such as strong sunlight.
Night vision mirror is an auxiliary observation tool based on night vision technology and with the help of photoelectric imager. Night vision technology includes low light level night vision and infrared night vision.

2. Different effects
The special effect of polarizer is to effectively eliminate and filter the scattered light in the beam, so that the light can be put into the visual image of the eye on the light transmission axis on the right track, so as to make the field of vision clear and natural.
Low light level night vision goggles magnify the weak light to present a clear picture in the line of sight. Therefore, under the condition of no light at all, low light level night vision goggles can't see anything; Active infrared night vision goggles can see things under any circumstances. If there is no infrared source, passive infrared night vision goggles can't see things.

3. Different usage
Polarizer can be used in driving, fishing, skiing, rain and other times with strong reflection or strong light.
Night vision goggles are usually used at night and are widely used in transportation, military and other fields.

2.How to choose night vision glasses
1. Lens material
The material of the lens affects the effect of eye protection. The driving mirror made of polarizing lens should be selected, which can effectively reduce the glare of dazzling lights and lamps, and filter out excess light. When wearing at night, the strong light becomes soft and the field of vision becomes clearer, so as to ensure the safety of driver friends and alleviate eye fatigue. If you can, ask the salesperson to turn down the light when shopping, and feel the softness and clarity of the light after wearing the product.

2. Radian of glasses
On the one hand, the comfort of polarized driver's glasses depends on the radian of glasses. Westerners' nose bridge is generally very high, while the outline of our Oriental nose bridge is round. Therefore, we can try it on when selecting. After wearing it, we can feel whether it is easy to fall off and pinch the nose. It is most important to choose glasses suitable for us.

3. Nose support of glasses
When drivers buy night vision goggles, they should choose the kind of nose support that is very soft and elastic. In this way, it won't make our drivers feel uncomfortable.

4. Observation mirror leg
The flexibility of the driver's mirror leg is also very important. Check whether the mirror leg is flexible and can be adjusted to meet the needs of different driver friends. The flexible mirror leg will be easier to adjust and make the driving friends feel more comfortable.

5. Frame material
The driver's glasses made of alloy should be selected. The glasses made of this material are very light, not heavy, but also strong. The ears will not be uncomfortable due to wearing glasses for a long time.

6. Lens thickness
The thickness of driver's glasses affects the use of glasses to a certain extent. The glasses with thicker lenses can be more durable, so as to prevent the glasses from being stimulated and accidentally broken, and effectively protect the eyes of driver friends.
