Polarized lenses are employed mainly for sunglasses, they provide protection from the Sun and the light levels, allowing for better vision under certain conditions. The ability of small lenses on a reflective light, such as the Sun to cover the engine, or on the surface of the water body has made them invaluable to many out there for business or leisure. Where as once something only those who work on the water you need, the ability to eliminate glare has now widely used, these lenses.
So how exactly they work?
Sunlight is absorbed by what is not, as he himself and polarized. In cases when it is not absorbed, it is one of the ways: vertically, horizontally or diagonally. So you can dictate how light is reflected; When sunlight shines on the surface of the horizontal wave of light, reflection results be horizontal. Reflection in turn strikes your eyes in a similar way, with the same type of angle, resulting from acts. Polarized lenses are manufactured with a special filter that was created specifically to reduce the luminance by blocking the light returned when he forefront. The filter is actually a series of small vertical format tracks, similar to the set of Venetian blinds. These tracks serve as a filter to block the light horizontal light vertical polarized and only enter, thus eliminating a glow.
A simple example (* excellent way and to make sure that the polarized lenses are polarized indeed ones) is to look at the surface of the reflective (example: the hood of the car) while wearing polarized lenses. If you change the viewing angle slowly by tilting the head left or right, should be a light in the fall.
While the polarized lenses may be a great assistance to certain people and certain scenarios, it should be noted that the ability to reduce the horizontal light will not be applicable in all situations where wearing sunglasses or protective eye are worn.
Best uses?
The use of polarized lenses was introduced to the public when fishermen discovered glasses with lenses polarized enabled them to see not only below the surface of the water, but also eliminated glow with the light lens Sun reflects off the surface of the water. After a short time, many other people in both professional and civilian began to use polarized lenses. Polarized lenses will eventually become a standardized industry deals, discounts and sales.
In fact, you can put a polarized lenses for use whenever there is a need to reduce or reduce exposure to sunlight reflected to maintain clarity. Typical uses of be when you are fishing, driving, running or aerobics, sailing and cycling.
If you already have gone to the cinema to film 3D for the past two years or so, you've used polarized lenses. Where the influence of the three dimensions is obtained once by using the familiar red and blue and as part of the new technology of stereoscopic, 3D uses polarized lenses. The big difference is instead of one red lens and one blue lens, 3D glasses now use polarization vertical and horizontal polarization lens, lens, and a new 3D glasses for a reason to use shaded grey lenses. Polarization different in each eye means your brain processes each kind of polarization to create a realistic feeling of depth in the picture on the screen. This is how the hyper-realism, three seeing 3D depth of films such as Tron: legacy, avatar, up! Is achieved.
