Polarized sunglasses are functional glasses that can effectively reduce glare

polarized Sunglasses are a kind of functional glasses that can effectively reduce glare, the following is detailed:
First, the working principle
Light is a kind of electromagnetic wave, its vibration direction is omnidirectional. When light reflects off the surface of an object, it forms a glare that vibrates horizontally. The lenses of polarized sunglasses contain a special polarizing film that filters out these horizontal vibrations of light, allowing only vertical vibrations of light to pass through.
For example, when you are fishing on the surface of the water, the sunlight reflected from the surface of the water can create a strong glare, making it difficult to see fish in clear water. Polarized sunglasses block out those glare and let you see underwater.

Ii. Advantages
Enhanced visual clarity: Glare reflected from the road, front car body or other objects can interfere with vision during driving. Polarized sunglasses can significantly reduce these glare, allowing drivers to see traffic signs, road conditions and pedestrians more clearly, improving driving safety.
Reduce eye fatigue: Long exposure to bright light and glare, eyes are easy to fatigue, dry, sore. Polarized sunglasses filter the glare, make the light received by the eyes more soft, comfortable, reduce the burden on the eyes, especially suitable for people who spend a long time in outdoor activities, such as skiing enthusiasts, hikers and so on.
Improve color contrast: it can make the color of the object more vivid, real, enhance the contrast of the color. For example, when enjoying the scenery, the blue sky, green trees, red flowers and other colors will appear more vivid and vivid, allowing the wearer to enjoy a clearer and more comfortable visual experience.
Third, lens material
Glass lens: with high optical clarity and hardness, good scratch resistance and wear resistance. But it is relatively heavy and easily broken, which can cause eye damage. This kind of lens is often used in some high-end polarized sunglasses or professional fields that require extremely high optical performance.
Resin lens: light weight, not easy to break, more comfortable to wear. Its optical performance is also good, and its function can be enhanced by adding various coatings, such as anti-ultraviolet coating, anti-fog coating and so on. It is the most widely used lens material in polarized sunglasses at present.
PC lens (polycarbonate lens) : The impact resistance of this lens is very good, several times that of ordinary resin lenses, and it is very suitable for wearing during sports, such as skiing, mountain biking and other extreme sports, which can effectively prevent damage to the eyes caused by accidental collision.

4. Application scenarios
Driving scenarios: Whether on a sunny highway or facing the reflection of buildings and vehicles in urban roads, polarized sunglasses can effectively reduce glare and allow drivers to better see the road and traffic conditions.
Water sports: surfing, sailing, fishing, etc. The glare caused by sunlight reflected from the water surface is very strong, and polarized sunglasses can make the field of view on the water clear, allowing users to observe underwater objects or waves.
Snow sports: In the snow environment, the sunlight reflected by the snow surface will produce a lot of glare, which is one of the reasons for the so-called "snow blindness" phenomenon. Polarized sunglasses filter out these glares, protecting the eyes while allowing skiers, snowmobilers, and others to see the terrain and their surroundings more clearly.
Daily outdoor activities: such as hiking, mountaineering, cycling and other activities, polarized sunglasses can reduce the glare reflected from the road, leaves, rocks and other objects, make the surrounding scenery more clear, but also make the eyes feel more comfortable.
