Everything You Need To Know About Polarized Gascan

By Jerri Perry


Polarized gascan sunglasses are a special line of sunglasses that use polarized lenses. These accessories are used to minimize or eliminate the unwanted effect of glare and also provide added protection for the eyes. These glasses differ from standard, non polarized ones by treating light waves differently.

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.

Light waves travel in different directions and that is how visible light is created. What helps us see are the light waves that travel vertically while horizontal light waves are responsible for glare. Glare is created when light is concentrated and is reflected by shiny, flat, horizontal surfaces.

What non polarized lenses do is randomly filter the light coming from all directions, may it be horizontal or vertical. This minimizes glare but it does not totally eliminate it. Since even the vertical light is filtered as well, the wearer's visual clarity is also affected.

On the other hand, Plutonite lenses uses a special kind of filter. They let the vertical light to pass through the lens, which gives the user a clearer vision. Furthermore, the horizontal component of light is totally eliminated which makes it pretty effective in eliminating glare.

These sun glasses are best suited for people who are engaged in any water sports. The flat and reflective water surface is well known to cause glares. The flat water surface creates glare by reflecting and partially polarizing the horizontal light waves. By eliminating glare, these sunglasses help make the water look much clearer as it helps you see what is beneath the surface. Furthermore, peripheral vision is improved by XYZ Optics, a technological innovation that maintains visual clarity at different angles of view.

These accessories, though helpful most of the times, are not always preferred. For example, when skiing on icy conditions, identifying patchy snow is easier since they cause more glare that snow. Wearing these lenses makes it harder to identify these patches and may be dangerous to the skier.

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.

Depending on the manufacturer, these specialized lenses are created using different technologies. The polarized gascan lenses uses the process of liquid infusion. This makes it possible to bond the filters at molecular level. In this process, two lenses will be cut from a single lens shield with a special curve, and are then attached to the frame to maintain the original, continuous contour. On top of it, the frame is also stress resistant and lightweight. Furthermore, numerous tests have proven that the accessory meets the ANSI Z87.1 standards for impact protection which gives it reliable protection for those who wear it.
