Polarised vs non-polarised sunglasses, which ones are the better sunglasses? Unless you're in the sunglasses industry, you're probably confused between the differences between polarised and non-polarised sunglasses. We will go to the bottom of how they differ, as well as how they are similar. We'll also get down to the final verdict of this showdown between these two types of sunglasses.
A Primer on How Light Works
Before we tackle the polarised vs non-polarised sunglasses debate, it helps to understand how light works. When the light from the sun hits the Earth, it gets absorbed, reflected, and refracted in many ways. This is due to the various elements within the environment. Water, glass, plastic, and the Earth itself all manipulate how light looks when it enters our eyes.
When light gets reflected, it will travel horizontally until it reaches our eyes. Depending on how intense the light is, it can cause us to feel discomfort or even pain in our eyes. In extreme cases, you can even experience temporary blindness. If you have ever looked at a glass building or a lake while the sun was reflecting off of it, you know about this all too well. If you don't have sunglasses on, especially polarised sunglasses, you are unable to protect your eyes from these types of situations.
What Are Polarised Sunglasses
Polarised sunglasses have been specially designed to get rid of glare completely. They have the ability to block vertical light, which is very important for people operating heavy machinery, such as a car. Others who can benefit from polarised sunglasses are those who fish, golf, ride bikes, run, or perform any other outdoor activity. Also, these are especially helpful while at the beach.
Along with this, mirror coating and anti-reflective coating can add protection for your eyes. Essentially, both of these tools are applied to your sunglass lenses and reflect light away from your eyes. Because UV rays can be so powerful, this reflecting property goes a long way in protecting your eyes from those serious eye conditions that we discussed.
Overall, the benefits of polarised sunglasses include the following:
• Less eyestrain
• Greater visual clarity
• Enhanced contrast
• Less or non-existent glare
• Greater colour accuracy
The only types of situations where polarised sunglasses should not be worn is when a pilot is flying an airplane and when someone is skiing downhill. Everyone else can enjoy the benefits of polarised sunglasses.
Usually, you will find that better quality sunglasses are the polarised kind that provide UV protection. However, it's important to remember that not all sunglasses that are polarised offer UV protection. This is why you should always check to see if the sunglasses you are interested in getting are both polarised and UV protective.
What Are Non-Polarised Sunglasses
Non-polarised sunglasses will reduce how bright the light is before it makes it to your eyes. This makes them helpful when there is strong light. However, there is absolutely no benefit to using them for the purpose of reducing glare. Their primary function is reducing the amount of light that gets into your eyes. Although this may seen helpful, it will usually be less beneficial than polarised sunglasses that reduce glare significantly.
Wearing non-polarised sunglasses can actually damage your eyes. This is because when you wear tinted sunglasses that are non-polarised, your pupils will dilate and get larger. However, since this type of sunglasses does not provide UV protection, your eyes receive a greater degree of UV radiation than they would with polarised sunglasses or without any sunglasses at all.
While non-polarised sunglasses may initially be less expensive, you may end up spending more on medical bills due to damage done to your eyes. It will be worth it to spend a little more to get polarised sunglasses that also offer UV protection.
Which Sunglasses Are Better
The verdict is in, and polarised sunglasses are both safer and more enjoyable to wear. They will keep harmful glare away from your eyes, ensuring you see the world clearly and vibrantly. You will avoid ever getting blinded, which can mean life or death in critical situations, such as while driving.
You should keep in mind that even if non-polarised sunglasses claim that they provide comfort when you're in the sun, they can cause more harm than good.
You should also make sure you are buying polarised sunglasses, since they can look very similar to non-polarised ones. Besides stating whether they are polarised or not, the ones that are polarised will have a higher price than their non-polarised counterparts. If there's a pair of sunglasses that seems to have too good of a price, it may be because they are non-polarised and lack UV protection.
Another way to figure out whether a pair of sunglasses is polarised or not is to take them for a test run outside. When you put them on and look towards the sun, or something far away that is lit up by the sun, what can you see? When everything looks clear and is not blurred or smudged, you are probably wearing sunglasses that have polarised lenses. If you're getting a great deal of glare and cannot see things clearly, you are likely wearing non-polarised sunglasses.
Getting polarised sunglasses will ensure you adequately protect your eyes and see the world clearly. There simply isn't any substitute for quality polarised sunglasses!
