In a colourful society, our eyes are constantly being tested, especially in outdoor sports such as fishing, where we have to endure not only direct sunlight but also bright light from the water. Therefore, a pair of polarizers was born to deal with this problem, and it has become an indispensable companion for many anglers and outdoor sports. This paper discusses in detail the working principle, manufacturing process, and distinguishing the true from the fake of polarized glass, which is helpful for people to further understand its scientific principles and application value.
Polarized glasses for outdoor sports.
Don't underestimate the polarizers you use when fishing outdoors. This method reduces reflections in the water column and increases visibility in the water, allowing anglers to better understand the movement of fish. The reason why this phenomenon occurs is because the special structure of the polarizer can effectively block the light from a certain direction, reduce the dazzling light, and improve people's vision.
Wave-particle duality and polarization principle in optics.
To understand how polarized light glass works, we must first know its wave-particle duality. Light comes in the form of waves and particles. Light is refracted on different materials (e.g. water), causing glare. Polarizing glass uses a special polarizer that allows light to pass through at a specific angle, so that the light that causes the glare can be filtered out.
The manufacturing process of the polarizer.
The central part of the polarizer is the polarizer, which is formed by elongating vinylon fibers and adding a dye. This method aligns the molecules in the film in a certain orientation, resulting in a property where only some light energy passes through. The polarizing film is applied to the glasses to prevent the refraction of light and reduce the harsh light, thus achieving the purpose of protecting eyesight.
How to identify polarized glass.
There are a lot of polarizing glasses on the market, so how to distinguish the real from the fake has become the focus of attention. An easy way to do this is to use an LCD screen for identification. Hold the polarizer facing the LCD, turn it slowly, and you'll notice that as it turns, the brightness of the screen changes. This is due to the fact that LCD screens use polarized optics, and polarized glass can block light from certain angles.
Conclusion. Polarized glasses are a very useful thing for people who are fishing or engaged in outdoor sports, it is a technological invention to protect eyesight and improve comfort. Through the understanding of the principle of polarization state optics, the preparation process and identification methods of optical lenses, we can help us better select and use polarized glass, and also deepen the understanding of optical properties and human visual mechanism. This understanding can not only enhance our experience of living in the wild, but also expand our understanding of nature and let us know how to love and care for our eyes.
