High energy visible light is blocked when either brown or gray polarized sunglasses lenses are worn. The importance to most wearers of this type of lens is reducing glare which can cause not only eyestrain but can obscure vision. Polarized sunglasses for fishing for instance will actually allow the wearer to see fish in the water which may be hidden to the naked eye.
Introduced several decades ago the use of polarization was once limited to a few brands of eyewear. Fortunately today many consumers can enjoy the benefits of this eye protection without sacrificing the style that they prefer. Most people today take for granted the availability of this excellent form of lens coating . Available in differing levels of glare reduction in prescription eyewear the amount of polarization may also differ in over-the-counter sunglasses as well.
Driving sunglasses will always be safer when the addition of polarized lens coatings are added. The areas of the country which experience several hours of bright sunlight will be obvious locations which need this lens coating. But even very cold places with lots of snow will be safer when drivers wear this anti-glare coating. Make absolutely certain to consider polarized coatings for sunglasses and goggles when engaging in outdoor sports. Those who work on construction or in road improvement sites will experience long hours of misery when glare is not combated.
Even some office workers these days work in modern office towers that allow tons of light. Even when smoke glass is used the light can require shielding and blinds are not available. Sore eyes can be avoided when even a very low percentage of polarized lens coating is applied to prescription lenses. Style isn’t sacrificed at all and there is no dark sunglasses appearance. Just a very light gray color is noticeable but work flow is greatly improved by this tiny adjustment.
After work and the drive home in traffic the consumer who has invested in dark polarized sunglasses can still enjoy watching the sunset. Bright light reflected from automotive chrome during traffic jams would other wise create painful eye strain. A work day spent squinting at the glare reflected on reflective glossy surfaces would surely create a certain amount of pain. But when appropriate levels of glare control are added to sunglasses throughout the day the evening can still be spent enjoying all the many uses of vision.
Polarized sunglasses extend our enjoyment of the day for hours. A bright summer day that starts with a glare filled sunrise commute can still leave pleasant evening hours of sports. Without polarized sunglasses bright days are a misery that requires rest in a dark room at the end of the commute home. Summer is too short to spend any part of it hiding from the sun. Take action to protect vision from all of the many dangers that threaten to take it away. The application of polarized sunglasses coatings are an important step in eye care.
Together with UV protection, polarized lenses make eyewear more health conscious.
