Sunglasses with polarized lenses

Glare caused by reflecting sunlight can be a genuine nuisance, especially when driving or engaging in outdoor activities. Sunglasses equipped with polarised lenses effectively reduce reflections, allowing sharper and more comfortable vision. Discover all that polarised lenses have to offer when it comes to delivering optimal protection.

Polarised lenses are designed with a special filter that blocks dazzling reflections caused by sunlight reflecting on surfaces such as water, snow, or the road surface. This filter allows only vertical light waves to pass through, thus considerably reducing glare while improving visual clarity and comfort. 

These lenses are particularly useful for outdoor activities, as they offer sharper vision and reduce eye fatigue.

The light from the sun is naturally polarised: its light waves vibrate in a particular direction. When reflecting off flat surfaces, these waves can disperse vertically or horizontally. In the latter case, they generate an uncomfortable glare effect.

The polarising filter acts as a barrier that only allows those light waves that are vibrating vertically to pass through. 

Polarised sunglasses offer several advantages when it comes to improving your visual comfort. By choosing this type of model, you will simultaneously benefit from:

• Sharper and more comfortable vision: polarised lenses considerably reduce the glare caused by reflections from flat surfaces. This can prove particularly important when engaging in various outdoor activities. 

• Reduced ocular fatigue: by reducing glare, polarised lenses also reduce the stress placed on your eyes. They are therefore recommended for all those who spend a lot of time outdoors and/or who suffer from particularly high sensitivity to light.

• Effective solar protection: like classic sunglass lenses, polarised lenses protect your eyes from ultraviolet (UV) light from the sun. Look for glasses with lenses that offer adequate UV protection, bearing the CE label. 

• A neutral aesthetic: polarised lenses are not discernible from other sunglass lenses. This option is available in several different colours.

Non-polarised lenses offer basic solar protection, by filtering sunlight. They reduce the glare caused by light coming directly from the sun, but do not block reflections from surfaces such as the road, water, or snow.

These glasses are therefore still useful in very bright conditions. However, they do not offer the same level of comfort and clear vision as polarised lenses.

In addition to reducing glare, polarised lenses improve the perception of contrasts in comparison to classic lenses.

Photochromic (or light-reactive) lenses are lenses that are initially clear, but offer the unique feature of automatically tinting when exposed to UV light. They then become clear again when in the shade or indoors, ensuring comfortable vision in all circumstances. They offer similar UV protection to classic sunglass lenses. 

The main advantage of photochromic lenses is their versatility. They are particularly valued by those who suffer from severe sensitivity to light.

Glare caused by reflections can prove particularly annoying when practising an outdoor activity. This is why these lenses are recommended for use in sport sunglasses: polarised lenses will contribute to improving your vision and your performance.
