What Are Polarized Sunglasses?
Actually, the polarized lenses are used to block or reduce the polarization (waves), a property of waves that can oscillate with more than one orientation. By wearing a pair of polarized sunglasses, around 90%-98% glare from reflections by horizontal surfaces can be reduced. This kind of sunglasses always provide wearers a better and clearer vision than people who wear standard sunglasses.
The polarized sunglasses have two types of polarized lenses which are 0.75mm and 1.1mm lenses. The 0.75mm lenses are made from thin sheets of film, while the 1.1mm lenses are thicker, which offers a better impact resistance than the 0,75mm lenses. As for the polarizing layer, the both are the same. Therefore, the vision the two provided are the same. Both can be applied in most casual sports, like running, fishing and golf. On the contrary, the thicker lenses usually make them a more expensive option.
How Do Polarized Sunglasses Work
We all know that the light that reflected by objects or surface such as water are polarized light, which need to be blocked by polarized lens. The polarized light always brings glare effect to eyes and affects the vision of people. Since the polarized light can be filtered by polarized lens, then you may wonder how the polarized sunglass works. To understand this, you need to understand what polarized light and the unpolarized light are.
What is unpolarized light?
The light such as flashlight, headlight or flame or sunlight is unpolarized light. This type of light always travels or vibrates in a variety of directions, just like an electromagnetic wave, that vibrate from up to down, side to side and so on. This light is erratic. The unpolarized light is the most common light in nature and it can be seen everywhere.
What is polarized light?
The polarized light is also moving like an electromagnetic wave. But it is different from the natural light. The travel direction or vibrating direction is simple. It only travels in a single direction, like a motion curve of fastball, which is a trail that would drop as it goes forward and won’t move side to side. Polarized light is always parallel to the surface, the unpolarized light approaches and be reflected.
How does the polarized light create?
We all know that most of the lights in nature are unpolarized. But how does the polarized light occur? Generally speaking, the occurrence of polarized light depends on the materials of the surface is and the angle of the light approaches the surface. Generally speaking, the light that is reflected by metallic surface is unpolarized and the light that is reflected by nonmetallic surface such as water, snow, ice or asphalt is polarized. And this is how the polarized light creates.
How does the polarized lens work?
The polarized sunglasses can block the polarized light for people or reduce the glare effect of us. But why the polarized sunglasses can filer the polarized light? It contributes to a special material people added in lenses. The special material added in lenses can arrange the polarized light and absorbed it. It only allows the unpolarized light pass through. And this is how the polarized sunglasses work.
