Everyone needs to protect their eyes and vision from the sun’s harmful UV rays. To maximize your benefits from sunglasses, Today's Vision eye doctors recommend that you consider polarized sunglasses.
Polarized sunglasses have been popular for years with boaters and fishermen who need to reduce reflected glare from the water surrounding them. But now that many others who spend time outdoors have discovered the benefits of polarized lenses, interest in these types of sunglasses has soared among bikers, golfers, and joggers, all who may enjoy a clearer view along with the elimination of glare. These sunglasses can be used for driving and, in fact, can reduce glare from a long, flat surface such as the hood of the car or the road's surface. You may wonder how polarized lenses work. Light reflected from surfaces such as a flat road or smooth water generally is horizontally polarized. This means that, instead of light being scattered in all directions in more usual ways, reflected light generally travels in a more horizontally oriented direction. This creates an annoying and sometimes dangerous intensity of light that we experience as glare. Polarized lenses contain a special filter that blocks this type of intense reflected light, reducing glare.Be aware that polarized lenses may reduce the visibility of images produced by liquid crystal displays (LCDs) or light-emitting diode displays (LEDs) found on the dashboards of some cars or in other places such as the digital screens on automatic teller machines and self-service gas pumps. With polarized lenses, you also may be unable to see your cell phone or GPS device.However, for many sports and activities, polarized sunglasses offer great advantages. And today, many polarized lenses are available in combination with other features that can enhance outdoor experiences.
