What are Polarized Sunglasses/Lenses? Polarized sunglasses have been popular for years with boaters and fishermen who need to reduce reflected glare from the water surrounding them, however now that many others who spend time outdoors have discovered the benefits of polarized lenses. Besides boaters, outdoor enthusiasts who benefit the most from polarized sunglasses include skiers, bikers, golfers and joggers, all who may enjoy a clearer view along with 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. Polarized sunglasses also can be worn indoors by light-sensitive people, including post-cataract surgery patients and those continually exposed to bright light through windows. How Do Polarized Lenses Work? Light reflected from surfaces such as a flat road or smooth water is generally 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. Though polarized sunglasses improve comfort and visibility, there are some instances when these lenses may not be advisable. One example is downhill skiing, where you don't want to block light reflecting off icy patches because this alerts skiers to hazards they are approaching. In addition, polarized lenses may reduce the visibility of images produced by liquid crystal displays (LCDs) found on the dashboards of some cars or in other places such as the digital screens on automatic teller (bank) machines. With polarized lenses, you also may be unable to see your cell phone or GPS device. Boaters and pilots also have reported similar problems when viewing LCD displays on instrument panels, which can be a crucial issue when it comes to making split second decisions based strictly on information displayed on a panel.

| Lens Tint vs Polarized Lenses? Although darkly tinted sunglasses may reduce brightness, they do not remove glare like a polarized lens. In addition, dark sunglasses without added ultraviolet protection may cause more damage to the patient’s eyes than not wearing sunglasses at all. The darkness of the lens can cause the pupil to dilate, letting more ultraviolet rays into the inner parts of the eye. Polarized lenses solve both problems by eliminating glare and filtering out harmful ultraviolet light because the filter reduces the polarized glare and also has ultraviolet absorbing properties. Today’s polarized lenses represent the best sunwear and outdoor lifestyle options available. With a little explanation and demonstration on your part, your patients will enjoy the benefits of these lenses for years to come. Advantages of Polarized Lenses
