The most prevalent words to come across when we talk about lens protection are either polarized or not polarized. Consequently, identifying it is not that obvious, and many people are not able to distinguish it from non-pole ones. And hence, getting the ones with local coatings Instead of complete polarized lenses.
However, in the next portions, we will discuss what polarization is. What is the easiest way to know if your sunglasses are polarized? What is the difference between polarized and non-polarized sunglasses? What are the benefits and drawbacks of using polarized glasses? And so on, So let’s get started.
What actually does “POLARIZED” mean?
Polarization, in literal meanings, can be defined as to eliminate the light wave into one direction or acquire polarity. Before grasping the concept, you must know several basics about the light first.
Originally, light travels in light waves e.g horizontal and vertical waves, not exaggerating about other orientations but the horizontal one is where the trouble begins because it bounces off in different directions which causes glare, blurriness and smudge in the vision not just that, but it is also very dangerous for sensitive eyes as it causes tears and strains in the eye.
So what does polarization actually do? Simple, it filters out the light travelling in horizontal orientation or we can say, polarize it, because it contains vertical straps that only allow vertically oriented light so as a result you’ll have a more clearer, glare-less vision.
What is the difference between polarized and non polarized sunglasses?
Considering the definition above, polarized sunglasses have polarized lenses that cut the glare and enhance the contrast by transforming light in the vertical direction while non-polarized sunglasses don’t.
The key distinction between polarized vs. non-polarized sunglasses is based on four factors:
Although, with non-polarized sunglasses, you can still see a less-glare picture. Yet they don’t block horizontally oriented light so chances are you’ll probably get interrupted by a lot of light over any lit places specially seas. Polarized glasses on the other hand, due to their light polarizing feature, blocks all the extra light creating glare in the vision.
Enhancing the Contrast:
Polarized lenses, having a specialized chemical coating, enhance the contrast according to the environment which might not be possible in non-polarized sunglasses. Though, it also depends on the lens color.
Non-polarized sunglasses, no matter if consisting of UV protection coating, light reducing ability but it is not effective for eye protection as compared to polarized sunglasses. Polarized sunglasses reduce the strain and fatigue. Therefore, they are effective for those having certain eye allergies or relatively normal sensitive eyes.
Clear and comfortable visuals:
The clarity of a vision pretty much depends upon the situation you are using a specific kind of sunglass. For example, for fishing or boating, or even driving you need vibrant vision which is only possible in polarized sunglasses e.g non polarized just lighten the contrast. Whereas, for skiing or flying non-polarized are more of an intelligent choice for a clear picture.
How to identify if the sunglasses are polarized or not?
Both polarized and non-polarized look the same which is why identification is necessary. However, there are simple tests through which you can determine whether or not your glasses are polarized. You can also click here simply get best polarized lenses from top brands.
You can either look at your phone screen where you will most likely sight a rainbow in the line of vision if your glasses are polarized. Also, polarized lenses darkened the LED lighted screen which is the easiest way to specify the difference between polarized and non-polarized sunglasses.
Alternatively, take a look at any reflected surface through your lenses and turn them 90 degrees, you’ll see a shiny reflection in case of lenses being polarized. Overall, one must also consider that even polarized sunglasses come in two variations i.e one that is thinner and the other is traditional heavy polarization so one must not confuse them with non-polarized ones. Thinner lenses allow readability through your digital screens. For further confirmation, you can also examine polarization by looking at the sun where the view will not get blurred or smudged.
Perks of having polarized sunglasses:
Nevertheless, both polarized and non-polarized reduce the bright light and clear the vision. Non-polarized lenses also reduce the glare but it does not “eliminate” it which is why you should always consider polarized lenses as it goes beyond the limitations. First of all, if you are most likely to get itches or allergies while at the sea or in bright environments, then you must wear polarized lenses due to its chemical coating as it reduces eye strain and damages especially for people with sensitive eyes.
For activities like fishing, surfing, or boating; polarized sunglasses are a must. The reason is that sunshine is reflected towards the sea that causes glare due to which you cannot sight a single fish, if you are an angler, making a pair of polarized lenses a necessity. Because of its light polarizing feature, you can view the depth of the sea without any extra light and glare interference.
Polarized lenses also come in handy if your eyes are allergic to shimmer or shiny displays hence they are medically useful in case if any other activities are not your concern otherwise. In addition to that, polarized lenses require additional care to keep them durable. Those you can find here. Contrast can be a real concern if your preferred athletic environments are bright and sunny. Here, polarized lenses come in useful as it enhances the contrast and filters the lights towards a more vibrant vision.
Nothing in this world exists without a con and so does the case is with polarized lenses. Even though they offer the best clearest vision possible without any glare while also protecting the eye. It is unfunctional when it comes to using our favorite gadgets such as phones, laptops, computers, LED screens, etc. This is because it uses vertical straps in the lenses which block vertical orientation resulting in the non-readability of your screens.
It also darkens the vision for color enhancement so the clear visuals of your phone screen could be problematic. This is the reason polarized lenses are not preferred for those who are engaged in continuous use of digital screens (LED, LCD, or phones) and as such as for pilots for they cannot read control panels and GPS screens. Additionally, there’s a misconception that polarization also meant protection from UV rays. Although many polarized sunglasses offer UV protection coating yet they don’t need to block UV rays in the majority of the cases so you must check the label before buying one.
for further details, visit are polarized sunglasses better.
Overall, The factor that distinguishes polarized vs. non-polarized is their impact on your eyes, managing reflected glare, contrast enhancement, and vision clarity which is only possible if your lenses imply Polarized technology. Although both polarized and non-polarized sunglasses protect from UV light e.g UVA, UVB, and other harmful rays plus reduces the brightness as well in the sun.
