Polarized Glasses Myths and Truths
For many years, eyewear with polarized lenses has gained popularity among boaters and anglers. It is a recent thing that has become a popular trend because it eliminates reflective glare dramatically. It makes easy to view fine details in the bright sunlight. Moreover, it is essential to know the truth behind some claims about branded safety eyewear with polarized lenses. Explore here some polarized glasses myths and truths.
Polarized lenses fully block glare:
The theory of polarization and glare is much complicated because of their interaction. Regular light moves on many surfaces. When light bounces off from a reflected surface, they become differentiated. This polarized light travels along one plane. A polarizing filter helps to block light that is reflected at a 90-degree angle. So more light is reflected horizontally rather than vertically.
Though, the relationship between glare, angle of the sun, and polarization of glare and filter show that polarized lenses will not be able to block the glare all time. Polarized sunglasses have traditional features like standard sunglasses. While RX safety glasses with polarized lenses don’t perform duties of polarization at all time, they cut the intensity of ambient light. Mostly they cut at least half of the light intensity.
If polarized eyewear is expensive then must be perfect:
Most expensive polarized glasses don’t exceed industry standards for UV security. Similarly, mostly inexpensive glasses with polarized lenses meet industry level and provide complete protection from UV. Make sure about the protection level for UV rays because UV shield stops harmful UV rays to reach into your eyes. These rays are not only harmful to eyes but skin as well. An additional layer for UV blocking must add with polarized lenses. With advanced technology, you can order online prescription eyewear with the desired coating.
Polarized glasses are helpful in driving:
Basically, this is true but depend on the sun’s direction. In the sunny days, the sunlight reflects from the glossy metal of cars that often happens on the road. Polarized lenses block reflected light to some extent, eliminate glare and make the safe drive. Yet, the polarized lenses can be affected when the sun reaches a certain angle in the sky.

Polarized lenses are not effective for LCD view:
This is true when the LCD displayed is watched from some specific angles, it may disappear. The light of LCD is polarized in such a way that polarized eyewear completely disappear it. Behind this reason, pilots who depend on LCD instrumentation are not allowed to wear these lenses for the sake of safe flying.

Polarized lenses are not available for bifocals:
Basically, this is true, polarized lenses don’t go with bifocals and trifocals. Because these lenses have been transformed in progressive lenses. They provide natural vision enhancement than older bifocals and trifocals. A polarization filter is available for progressive lenses.

Polarized lenses allow boaters to see clear in deep water:
This myth is partially true because of the nature of reflected light into water. They make easy to see well of objects underwater. The polarizing filter is applied vertically and water’s surface reflected light is polarized horizontally. You can apply to polarize filter on Rx safety glasses if you mostly practice for an outdoor workout. Therefore, it dramatically affects and eliminates glare on the water surface.
