In a nutshell, the polarized gascan are sunglasses that use special kind of polarized lenses. It does not only eliminate the unwanted glare and its detrimental effects, but it also provides enhanced protection for the eyes. What makes these sunglasses different from standard and non polarized ones are basically on how they treat the light waves.
Plutonite lens, a special type of polycarbonate lens, are used in these glasses. These lenses are made to block all UV rays and is also referred to as the lightest material used in modern lenses. Another desirable property is the low thermal conductivity. With this, the lenses do not heat up easily and therefore has lesser probability to fog.
The visible light is composed of waves that travel in different directions. Vertical light is what helps us see the objects on the surroundings while horizontal light creates glare. Glare is cause by concentrated light that is reflected by a shiny horizontal surface. More often than not, glare can vision difficulties.
Regular lenses merely filters light, whether it is horizontal or vertical. This minimizes the effect of glare but does not necessarily eliminate it. However, since vertical light is also filtered, visual acuity is also affected and is therefore sacrificed. This is why regular lenses have become a challenge for eye wear manufacturers.
However, polarized lenses use filters of special kind. The material allows vertical light waves to pass through. This gives its wearer a much clearer view. Meanwhile, horizontal light is blocked. As a result, the glare is also eliminated.
Since the flat and shiny water surface can add to the glare, people who are involved with water sports are best advised to use these accessories for best performance. The water surface polarizes the light waves partially through horizontal reflection. With these eye wear, glare is eliminated while the water appears to be more transparent allowing clearer view of what is below the surface. Aside from that, because of the XYZ Optics technology that helps maintain clarity of sight at any angle, the peripheral view is not sacrificed.
While these sunglasses are generally useful, there are cases wherein they are not supposed to be used. For example, skiing atop icy surfaces requires you to be careful on patches of ice which you can easily identify because they produce more glare than snow. Since these sunglasses filters glare, it is harder to check these patches.
Furthermore, viewing on LCD screens are also affected. So when involved in activities that use LCD display screens, such as piloting an aircraft or boating, the use of these accessories is not preferred. While some manufacturers have created ways to fix this issue, this is not true to all products yet.
Different manufacturers use different technologies to achieve polarized lenses. As for the polarized gascan sunglasses, it uses the liquid infusion process to bond the filter at molecular level. To achieve the design, two lenses are cut from one lens shield that has a special curve and are then mounted to a special frame which follows the original and continuous contour. The frame is also made lightweight and stress resistant. The impact tests also shows that it conforms to the ANSI Z87.1 standards that gives an assurance for added protection for the user.
