Polarized sunglasses contain polarized lenses. These lenses are treated with a special coating that gives them enhanced anti-blur and anti-haze protection, keeping your vision in the sun clearer than ever. This coating is where the magic happens and helps make polarized eyewear the premier choice of lens type for drivers, hikers, and athletes.
Polarized lenses filter out light in a horizontal orientation. While light can, of course, come in different orientations, horizontal light is particularly problematic because it causes glare from the surfaces it reflects off. This glare can range from unnoticeable or irritating to blinding and dangerous depending on your situation and the sensitivity of your eyes. If you have sensitive eyes or you find yourself in a challenging situation, you can see why polarized sunglasses might come in useful. Like non-polarized sunglasses, they still protect your eyes from bright light, harmful UVA, and UVB light but as an added bonus, you don’t get the glare that can come with regular sunglasses.
– Minimizes eyestrain
– Enhances contrast and visual clarity
– Improves visual comfort
– Eliminates/reduces glare
– Provides a more accurate perception of colors
– BUT, and there is a big BUT, polarized lenses are NOT for everyone. Operators of heavy equipment and airplane – pilots should not wear polarized-lenses as they make it difficult for people to see LCD screens (like the ones found on a cell phone or GPS) clearly.
Additionally, some downhill skiers do not wear polarized lenses because it can be difficult for them to differentiate between snow, ice and hills, only adding to the danger of the sport.
First of all, it is essential that glasses have reliable UV protection. Many people are unaware of the fact that when wearing sunglasses, the pupil dilates and this causes eyes to be exposed to ultraviolet rays. If the lens offers a low UV protection, this does not prevent the sun’s rays from reaching the eyes, which can permanently damage them causing macular degeneration leading to vision loss and cataracts. Therefore, it is better for your visual health to leave the house without sunglasses than to use a dubious quality.
However, when buying polarized lenses, this is a risk that the consumer will not have to worry about because these lenses offer 100% protection against UVA and UVB rays.
Another important benefit is that polarized lenses offer almost complete protection against the horizontal brightness of the sun, making the sun’s reflection almost imperceptible, making vision more defined.
In other words, polarized lenses are used to block out intense light that is reflected off flat surfaces. This is because polarized sunglasses are made with vertical polarization, while light reflected by the sun on flat surfaces is horizontally polarized.
Non-polarized lenses have a dark tint and reduce the intensity of light. However, unlike polarized lenses, they can not counteract the effects of horizontal polarization. These lenses do not take into account the meaning that the light reflects.
These lenses offer 100% protection against UVB and UVA rays, which we know are harmful not only to the eyes, but to the body as a whole. Other than that, take care of the vision against the solar reflections, softening and making them almost imperceptible. The difference for the driver, for example, is very large. In places with beaches, lakes and during strong sun, there is no way to compare the way a polarized lens and a common lens work. Being more than a matter of comfort or just aesthetics for those who work in such environments, the polarized lens can provide safety and quality vision.
Usually, when it comes to buying sunglasses, buyers will notice if they have protection against the famous ultraviolet rays. But what few people worry about is whether the lenses are polarized or not, but this is because some people do not know this benefit and often do not know the difference of this model. However, this detail should be taken into consideration, especially if you are seeking a high degree of comfort, quality and eye protection.
Of course, it is essential that the glasses have reliable UV protection, but some people are unaware of this importance. It is a fact that when we wear sunglasses, the pupil dilates and causes eyes to become more sensitive and exposed to strong rays – and if the lens does not offer high UV protection, this causes these sun damage to reach the deeper layers of the eyeball, gradually damaging them and causing macular degeneration, which can lead, in more severe cases, to cataracts and even loss of vision. That being so, sometimes it is better to leave the house without sunglasses, thinking about your visual health, than using a quality of doubtful.
almost imperceptible, if you are someone who is constant in outdoor activity, whether driving, playing sports or just lying in the sun, polarized eyeglasses are definitely the best choice!
