When the weather is scorching, doesn't it feel like you're blinded by the sun right off the bat? Especially for those who drive, not only do they have to battle the direct sunlight, but also deal with all kinds of glare reflected from the roads. It's so uncomfortable that one can almost cry.
At this time, a pair of sunglasses is definitely a must-have! Nowadays, many major brands are highlighting their polarizing properties in product promotions, and polarized sunglasses have gradually become popular among drivers.
So, do you know what a polarizing sunglasses is? Do you know its special functions? Let's keep reading!
So, what exactly does "polarized sunglasses" mean? Let's have Momnet 百科 enlighten us! Polarized sunglasses are a type of sunglass that has evolved in response to people's needs.
In our daily lives, aside from direct sunlight, light that passes through unevenly textured surfaces will produce irregular diffuse reflections. Polarizing sunglasses can filter out this type of light, absorbing only the reflected light of objects and accurately presenting what is seen.
The filtering principle is similar to that of a blind, adjusting the sunlight into a parallel beam before it enters the room, making it soft and not dazzling.
What are the functions of polarized sunglasses? Polarized sunglasses are becoming increasingly popular among car enthusiasts and outdoor enthusiasts, prompting many to buy one.
It seems that polarized sunglasses have an edge over regular sunglasses in functionality.
So, you know what is the function of polarized sunglasses? The most important function of polarized sunglasses is the "polarization".
Before we introduce the function of polarized sunglasses, let's first take a look at the light in our lives.
In our daily lives, aside from direct light, the irregularly reflected light caused by uneven surfaces such as roads and water is called glare.
The appearance of glare can cause discomfort and fatigue to the eyes, affect the clarity of vision, and bring many troubles to people's lives and travel. Especially for drivers who are driving, they are greatly affected.
Polarized sunglasses can effectively filter glare, scatter and refracted light, only absorbing the reflected light of objects, thus accurately displaying the visual image.
Therefore, polarized sunglasses can improve visual acuity and reduce eye fatigue, thus playing a role in nourishing and protecting the eyes.
In addition, polarized sunglasses, due to their efficient light filtering layer, can block up to 99% of ultraviolet rays, protecting the eyes from UV damage.
Polarized sunglasses come in various colors. When selecting different-colored polarized sunglasses, don't just focus on matching your clothing! The best choice is the color that suits your eyes! Let's take a look at different colors of polarized sunglasses now! 1. Gray lenses: They evenly absorb various light sources, making the view through them darker but without significant color distortion, allowing for a true and natural feeling, belonging to the neutral color category.
2. Teal-tinted lenses: They filter out a significant amount of blue light, thereby improving visual contrast and clarity. They are particularly effective when wearing them in areas with severe air pollution or fog.
3. Green Lenses: When absorbing light, they can maximize the amount of green light reaching the eyes, making them suitable for individuals with eyes that tend to feel tired.
4. Yellow lens: The yellow lens can hardly reduce visible light, but during fog and twilight, it can enhance visual contrast, making the eyesight clearer.
5. Light Blue/Light Pink Lenses: Light blue and light pink lenses are primarily decorative, with their filtering effects often not meeting expectations.
When is it appropriate to wear polarized sunglasses? Many friends have expressed that when they go out shopping or walking, a regular pair of sunglasses should suffice to protect them from all the glare. Therefore, there's no need to buy any polarized sunglasses.
What is the best time to wear polarized sunglasses? The polarizing angle and curvature of the polarized lenses are specially designed and processed, so that you won't have a sense of disorientation or dizziness when looking at objects. They are most suitable for fishing, driving, sports, sailing, skiing, hunting and other occasions.
In summer, anglers often wear polarized sunglasses because they make it easier to spot the bait and less eye strain when fishing.
At the same time, polarizing lenses are globally recognized as the most suitable glasses for driving.
Polarizers are made according to the principle of light polarization and have the special function of eliminating glare. They filter out chaotic light so that drivers can improve their vision and drive more easily.
Even those who love outdoor tourism have a special fondness for polarized sunglasses, which can enhance the contrast of colors, reduce glare, and increase the saturation of scene colors. It allows you to see a clearer world.
People are well aware of the difference between polarizing sunglasses and non-polarizing sunglasses, and both driving enthusiasts and fishing enthusiasts often wear one to better enjoy their activities.
Meanwhile, my friends think that just wearing regular sunglasses is sufficient.
So, do you know the difference between polarized sunglasses and non-polarized sunglasses? Non-polarized sunglasses generally only have two basic functions: blocking strong light and filtering ultraviolet rays. However, their efficiency in filtering ultraviolet rays is relatively low.
When engaging in outdoor activities under strong sunlight, the glare from all directions can cause blurred vision and fatigue.
Polarized sunglasses can effectively filter out glare and only absorb the reflected light from objects, thus accurately presenting the visual scene and reducing visual fatigue.
In addition, polarized sunglasses with their efficient filter layer can effectively block 99% of ultraviolet rays, reducing the damage to the eyes caused by ultraviolet rays.
