When it comes to protecting your eyes from the sun, polarized sunglasses are a popular choice. They not only protect against UV rays, but also reduce glare from reflective surfaces such as water, snow or windshields. But what is polarization and why should you consider polarized sunglasses? In this article, we explain everything you need to know to enjoy a clearer and more comfortable vision.
What is polarization?
Polarization is a process of filtering light according to its propagation direction. In fact, the reflected light on certain surfaces such as water, sand or snow is scattered in all directions, creating a dazzling intense and sometimes unpleasant for the eyes. This phenomenon occurs because reflected light is often polarized horizontally, disrupting our vision and creating a dazzling effect.
Polarized lenses are designed to block the reflected light horizontally by allowing only vertical light to pass. This eliminates glare and offers a clearer and more contrasting vision. Thanks to this technology, polarized sunglasses are ideal for many outdoor activities and in bright environments.
Polarization is often seen as an additional asset for sunglasses, as it significantly improves visual comfort. By reducing the amount of light that enters your eyes, you can better distinguish the details and enjoy a more pleasant and relaxing visual experience.
How does the polarization of sunglasses work?
The polarized lenses contain a special filter that blocks horizontal polarized light. This filter is made from horizontally aligned molecules, which absorb light oriented in the same direction and allow the one that is oriented vertically to pass. This means that glare caused by horizontal surfaces is considerably reduced.
In other words, polarized sunglasses act as a selective barrier that only passes useful light, while blocking the one that causes glare. This process improves the perception of colours and contrasts, allowing to see more clearly and with less visual fatigue, especially in the bright outdoor environments.
To understand well, imagine a Venetian blind: when the blades are oriented horizontally, they block the direct light while letting pass the one coming from another angle. Polarization works in a similar way, allowing only useful light to pass, while eliminating annoying reflections.
The advantages of polarized sunglasses
Polarized sunglasses offer many benefits, particularly in terms of visual comfort and protection. Here are some of the main benefits to consider if you plan to equip yourself with polarized glasses.
First, the elimination of glare is one of the main advantages of polarized glasses. Whether you are by the sea, in the mountains, or even in the city, they reduce reflections and improve your vision. This allows you to see clearly without being bothered by the reflected light, which is particularly useful for nautical activities and driving.
Polarized glasses also improve color contrast and perception. By eliminating glare, they make it easier for you to distinguish details and see the objects around you. This is particularly beneficial for athletes, hikers and those who like outdoor activities, as a good perception of contrasts can improve their experience.
Finally, polarized sunglasses offer additional UV protection. Although polarization does not directly filter UV, it is often associated with lenses that block harmful rays, thus ensuring complete protection for your eyes and reducing the risk of visual fatigue.
In what situations do polarized sunglasses wear?
Polarized sunglasses are not only aesthetic; they are particularly useful in certain specific situations. The following are examples of environments and activities where they are essential.
For nautical activities, polarized glasses are essential. Whether you do sailing, water skiing or fishing, the reverberation of the sun on the water can be very intense and tiring for the eyes. Polarized sunglasses allow you to see more clearly under the surface of the water and avoid glare.
Polarized glasses are also ideal for driving, as they reduce glare on reflective surfaces such as bitumen or windshields. They enhance visual comfort by reducing direct light and provide better visibility, which increases safety when driving in sunny weather.
In the mountains, polarized glasses are precious to protect the eyes from the reflections of snow, which can be blinding. By reducing glare, they make it possible to better distinguish reliefs and prevent visual fatigue, which is essential for skiers and hikers at altitudes.
Potential disadvantages of polarized sunglasses
Although polarized sunglasses offer many advantages, they also have some disadvantages that it is important to know before making your choice.
In some situations, polarized lenses can make it difficult to read LCD screens, such as car dashboards or GPS screens. Polarization interferes with the light emitted from these screens, which may result in loss of visibility. This can be awkward for some drivers or users of digital devices outdoors.
Polarized lenses can also be more expensive than non-polarized lenses. Their manufacture requires special treatment, which can increase their price. However, the comfort and visual benefits they bring are often worth it for those who spend a lot of time outdoors.
Finally, in low-light situations, such as dusk or cloudy days, polarized lenses can sometimes reduce too much light and make vision slightly darker. This does not make them ideal for all conditions, although they are perfect in full sun or in bright environments.
How do I know if your sunglasses are polarized?
It is possible to check whether your sunglasses are polarized with a simple test. If you do not find the indication on your glasses, follow these steps to get a clear heart.
The most common method is to watch an LCD screen, such as a phone or computer, by holding your glasses in front. If the lenses are polarized, you should observe a darkening or a change of color by tilting your glasses to 60 degrees from the screen. This change in brightness is an indication that lenses filter reflected light.
You can also try to observe a reflective surface, such as water or a car. If glare is significantly reduced with glasses, this indicates that they are likely polarized. However, if you do not notice any significant difference, it is likely that your glasses are not.
