However, polarized lenses can make it more difficult to see patches of ice on the roads. You should also avoid wearing sunglasses when driving at night — polarized or not — because they can make it harder for you to see and react in a timely manner.

Circularpolarization

Unpolarized light disperses in all directions as it reflects off uneven surfaces. When light is polarized, however (like through polarized lenses), it reflects within a single plane. For instance, sunlight bouncing off water can create a glare that makes it difficult to see clearly, especially when looking into the water.

Costa 580 lenses feature proprietary in-house technology, offering a polarization efficiency of 99.9% and nearly 100% glare reduction. These lenses enhance colors by filtering out harsh yellow light at 580 nanometers. This elevates red, green and blue light for enhanced contrast, vibrancy and clarity.

Glare from the water’s surface can decrease visibility when you’re looking into the water. This can lead to eye strain as well as missed opportunities. Polarized glasses have a special filter in the lenses that reduce glare from water and other reflective surfaces.

Polarized lenses can also be helpful when driving, though caution is advised. They are wonderful for daytime driving because they can reduce glare from light reflected off roads, cars, buildings and other surfaces.

Disadvantages of polarized sunglasses

Whatispolarization

Polarized (or anti-glare) lenses function as optical filters. They contain a unique chemical that filters the horizontally polarized light that causes the harsh glare often encountered on water and other surfaces. By only allowing vertical light waves through to your eyes, this chemical filter helps decrease glare, improve contrast and boost visual clarity.

Polarized glasses offer benefits for other outdoor adventures. From golfing to hiking, anti-glare lenses can help you enjoy the world around you with greater precision and enhanced color contrast.
