Polarized sunglasses are essential for outdoor sports enthusiasts. If you don’t partake in outdoor sports you should also consider the utility of polarized sunglasses for other outdoor excursions such as driving, hiking or even gardening. Any flat surface such as standing water, a road or snow can create reflected glare that can play havoc with your vision. Polarized lenses can be beneficial indoors also.
Polarized lenses are designed to use wave technology to easily cancel out unwanted light from contacting your eyes. When the sun shines on snow, water or any other reflective surfaces, the reflected light becomes polarized. This means that most, although not all, of the reflected light waves move in one single plane. Normal light moves in many planes but polarized lenses allow only light in one plane to pass through the lens to your eye. This eliminates much of the glare.
Although light from the sun is not polarized, when it is reflected by the surface of a standing body of water it is separated into two polarized components that are reflected and transmitted in different amounts. In most cases more of the horizontal component will be reflected than the vertical component. This reflected light is said to be partially polarizing. A lens that is vertically polarized can then be used to help eliminate the glare. There are a number of variables that can affect the degree of polarization and the effectiveness of polarized sunglasses such as the height of the sun. However, polarized sunglasses will not eliminate all reflected light. They can only eliminate some of the reflected light that helps reduce the glare.
Polarized photochromic lens are great for light sensitive individuals. These lenses adjust to the level of light present in the environment. For instance, if you are inside where there is a low light level the lens will visibly lighten or outside where there is abundance of light it will become darker and block more of the glare reaching your eyes..
Progressive lenses or prescription lenses or tinted lenses: there are so many options for your polarized sunglasses if you are an outdoorsman. There are looks and styles to appeal to everyone. With polarized sunglasses you will have the assurance that your eyes are safe and your vision is not compromised from the harmful effects of the sun while pursuing the outdoor activity of your pleasure.
Choosing the right pair of polarized sunglasses can be enjoyable if you have the all the information necessary to make good decisions. Sunglass styles can be a personal choice.
But knowing about polarization and other lens enhancements will ensure that the sunglasses you select will give you many hours of protected outdoor fun.
