For many, sunglasses are an indispensable tool for the summer.
Whether it's going to the beach for swimming or going out on a picnic, putting on a pair of fashionable sunglasses can make you look more stylish.
Nowadays, many big brands of sunglasses emphasize their polarizing characteristics when promoting their products. Polarization seems to have become a unique product feature that has been widely recognized by everyone.
What are the differences between polarized sunglasses and non-polarized sunglasses? And how can you determine if a pair of sunglasses is polarized? Let's continue to explore this together! The difference between polarized and non-polarized sunglasses is vast, with many sunglass brands offering polarized versions. However, many people still confuse polarized and non-polarized sunglasses! So, do you know the differences between these two types of sunglasses? Non-polarized sunglasses typically only have basic functions such as blocking strong light and filtering ultraviolet rays, with a lower efficiency in filtering ultraviolet rays.
However, do you know that in our daily life, besides the strong light and ultraviolet rays, irregular reflection of light through uneven roads, water, etc., causes people's eyes to become blurry and fatigued.
Polarized sunglasses can filter out such light, absorbing only the reflected light from objects and genuinely presenting what you see, thereby reducing visual fatigue.
In addition, polarized sunglasses have an efficient filter layer that blocks up to 99% of the ultraviolet rays, effectively reducing damage to the eyes from UV rays.
How to Determine if Sunglasses Are Polarized? Polarized sunglasses and non-polarized sunglasses have no differences in appearance, but how can you tell whether a sunglass is polarized? Mom's Net Knowledge has a clever trick! When determining whether sunglasses are polarized, you can rotate the sunglasses clockwise by 45 degrees.
If the color of the lens changes when it is turned back to its original position and then returns to normal, this means that the sunglasses are polarized.
If no color change is visible when the sunglass lens is rotated, it can be concluded that this sunglass is not polarized.
Which is better, polarized or non-polarized sunglasses? Given that sunglasses are categorized into polarized and non-polarized types, how should one choose the right pair for their needs? Below, MaNet WeChat will introduce the appropriate sunglasses based on your diverse requirements! Humans often need to adjust the size of their pupils to regulate the amount of light entering the eyes when exposed to sunlight. However, if the intensity of the light exceeds what the human eye can control, it can cause harm to the eyes.
Therefore, in summer, many people wear sunglasses to reduce the damage caused by strong light on their eyes.
Generally speaking, for short-term outdoor activities, sunglasses without polarized lenses can already meet your needs.
If you're driving, fishing, traveling, or skiing, the Mawang Encyclopedia recommends choosing polarized sunglasses for their enhanced functionality. Polarized lenses provide a polarizing effect, allowing your eyes to remain comfortable under strong sunlight and effectively protect them from long-term exposure to bright light.
What is the function of polarized sunglasses? Polarized sunglasses are a type of sunglasses that have emerged in response to an increasing demand. Many drivers purchase them for themselves. So, what exactly are the functions of polarized sunglasses? Before we discuss the functions of polarized sunglasses, let's first understand the light in our daily lives.
In our daily life, besides the strong light and ultraviolet rays, there is also an irregular diffused light when the light passes through the uneven road surface or water surface.
The appearance of glare makes people's eyes feel uncomfortable and tired, and affects the clarity of objects. It brings many troubles to people's lives and travel, especially for drivers who drive.
At this point, polarized sunglasses found their rightful place.
Polarized sunglasses can effectively filter glare, scattered light, and refracted light, only absorbing the reflected light from an object, and accurately present what is seen.
Therefore, polarized sunglasses can improve visual acuity and reduce eye strain, thereby playing a role in nourishing and protecting the eyes.
In addition, polarizing glasses can also block all ultraviolet radiation, protecting the eyes from the harmful effects of UV.
How to choose polarized sunglasses, after seeing the advantages of polarized sunglasses, many friends have expressed that it is time to buy a pair of polarized sunglasses.
So, you know how to choose polarized sunglasses? Let's mark it down! First of all, make sure to choose high-quality polarized sunglasses. Good polarized sunglasses can completely block ultraviolet rays.
2. When choosing polarized sunglasses, Yan should also adhere to the principles of maintaining true colors in the surrounding environment, clearly distinguishing edges of objects, and effectively recognizing different color signals.
3. Before purchasing polarized sunglasses, make sure to try them on and check if you feel discomfort, dizziness, headaches, dryness or irritation of the eyes.
4. When selecting polarized sunglasses, it is also important to pay attention to the protective function of the frame. High-quality polarizing sunglass frames are designed with concave curvature, which can effectively prevent foreign objects from stimulating the eyes in outdoor sports activities.
