Sunglasses are an essential accessory for summer. Your choice will depend on several parameters: the color, the shape, or even the size of the lens. However, do not forget that their main use is not to be pretty but to protect you from the aggressive rays of the sun. So to be sure to make the right decision, we will see what the real advantages of polarized sunglasses are.
Polarized sunglasses: definition
Sunglasses are sometimes an essential ally for hitting the road or avoiding eye strain during a walk. To understand what a pair of polarized glasses is, let’s look at the principle of polarization. Initially, light waves move in all directions and are reflected on each flat surface they encounter, which changes their vibration axis.
On the other hand, so-called “polarized” light only vibrates on a horizontal axis, which is what causes glare. Polarizing glass will counter this problem by acting like a Venetian blind. That is to say, it will block the polarized light and therefore the glare to only let the light pass on the elements being viewed. So visibility is increased and we have a better reading of the information. In other words, we can see the details more clearly since the glass will filter the light.

In what situations should you wear them?
This is currently the best option for athletes who encounter reflective surfaces. This system works in all situations, even the most extreme, namely:
- In the water: this is the ideal solution for water activities such as fishing, and it is in these cases that the performance of polarized lenses is most effective since they eliminate the reflection of light on the water to improve vision and prevent the eyes from getting tired. In addition, for high-level athletes, these glasses allow you to spot the movements of the wind on the water, an essential asset in competition.
- On a very sunny road: in addition to the feeling of comfort which is satisfactory, with these glasses, you can prevent dangers more easily. Without the reflections that you see on the road, it is easier to analyze the information that you constantly receive when you are driving. When you go on vacation or when you travel long distances, they are therefore of inestimable help, whether the light is in front of the driver or reflected by the road or vehicles. These are the only glasses that will bring you such comfort.
- On snow: the glare is very strong on this white and sparkling material, it is, therefore, essential to have quality glasses to protect your eyes from the harmful rays of the sun but also to avoid dangerous falls due to a poor appreciation of distances and reliefs.
For whom?
Polarized lenses are suitable for everyone without exception and of course for all situations. Athletes are the ones who wear them the most since they need clear information to gain precision. But everyone can appreciate the quality of protection they offer against UV rays as well as the comfort they provide.
Elderly people or those with poor vision can find some relief in this. While polarized sunglasses are still struggling to find their place in the French and European markets, Americans only wear them! The United States and Australia represent 90% of sales worldwide.
