Protecting your eyes against the harmful effects of UV rays is very important if you don’t want your vision to be damaged early on in life. The best way to achieve maximum protection for your eyes is to keep them covered with sunglasses. Sunglasses not only keep your eyes covered but also protect them from excessive straining. However, when you are about to purchase sunglasses, there is one important question you need to answer, and that is whether to buy polarized sunglasses or non-polarized ones.
Polarized vs. Non-Polarized Sunglasses
There are several features a polarized pair of sunglasses can offer its wearer. The sole purpose of a polarized lens is not to merely protect the eye against UV rays, but to also increase clarity and accuracy of vision. However, there are some downsides to these glasses. Therefore, when you have to decide between polarized vs. non-polarized sunglasses, there are several important factors you need to consider before you come up with a decision.
The first and the most important thing to consider is whether the pair of sunglasses you are buying, either polarized or non-polarized, offers maximum UV protection against the sun or not. Even when you are buying ray ban eyeglasses, not all of them come with excellent UV protection. Because the use of sunglasses makes the pupils widen, the eyes become more vulnerable to sun rays if the UV protection is poor. Therefore, you should always be completely sure that the lens you are buying offers 100% UV protection, which is quite probable if you are buying polarized sunglasses.
Another benefit you can get from buying polarized sunglasses is protection against the horizontal glare of the sun, which is responsible for unclear vision. The glare of the sunlight is quite intense and has a higher potential of damaging the eyes than scattered rays. These horizontally polarized rays make it quite more difficult to see things clearly in the sunlight.
While normal sunglasses can reduce the intensity of this light, they cannot counter the effects of polarization. Since polarized sunglasses are made with vertical polarization, they deflect these rays and offer perfectly clear and accurate vision. Therefore, polarized glasses are quite preferable when used during sports or driving since they can reduce the chances of accidents.
With all these benefits to offer, polarized sunglasses are definitely a better option to be considered than non-polarized sunglasses. However, when making the decision between polarized vs. non-polarized sunglasses, you also need to consider some downsides of polarized lenses. The most major issue with polarized sunglasses is the poor visibility they offer in case of LCD images.
Images produced by liquid crystal display often become unclear or even invisible if viewed through polarized sunglasses. This can make it difficult to view cell phone screens and other flat LCD screens, especially those used in GPS devices found in cars and boats. This can be quite a problem if you are wearing these glasses while driving when you constantly need to consult the GPS device.
The difference between polarized and non-polarized
Price is also one of the most important factors to consider when it comes to deciding between polarized vs. non-polarized sunglasses. Due to the high-tech lenses used in polarized sunglasses, their prices are undoubtedly quite higher than those of the non-polarized ones. If you are buying high-quality, custom-made polarized sunglasses, they can cost you hundreds of dollars. On the other hand, you can get a non-polarized pair for a lesser amount. However, there are some polarized sunglasses that are also available at lower prices, but these don’t offer many customization options.
So, keeping in mind the benefits and downsides of polarized sunglasses as compared to non-polarized lenses, it is completely up to you to decide which one you want to purchase. However, if the ultimate protection of your eyes is your major concern, polarized glasses will definitely be a more viable option to be considered.
