Polarized sunglasses have been worn for decades by anglers or boatmen since they offer a clear vision in water environments. Polarized sunglasses are just the UV sunglasses integrated with polarized lenses that are capable of reducing the glares from the smooth surfaces such as water, snow, highway. The glare strikes directly to the eyes can cause a blurring vision, eyestrain, and distorting the true color of objects.

Sunlight from the sun scatters around us, it becomes polarization only it encounters a flat surface like a lake or open water. Polarization a process to create the vertical wave and horizontal wave. The vertical wave is good to the eye but the horizontal wave is the main source to cause the blinding glare.
A laminated filter inserted into polarized lenses help to filter out the horizontal wave while allowing the vertical wave to pass through, thus glass wearers will experience a clear vision and true color of images. When it comes to UV protection, polarized sunglasses provide the same performance as other shades.

For these benefits, polarized lenses can be useful for certain outdoor sports or other activities where the glare is present as fishing, driving.
