What are Polarized Lenses
They are transparent lenses, usually made of glass or plastic, which help block certain types of light waves. They are hugely in demand and many websites and stores provide special discount codes on polarized lenses.
Most sunglasses and camera lenses are equipped with a polarized lens to improve the result. They reduce the glare from the surface. A polarized lens blocks around 50% of the light that passes through it which greatly enhances vision. It enables people to see more clearly by reducing the brightness and glare of the light.
How Do They Work
Why are they so much in demand? Why are so many companies making them and offering polarized lens on discount? Simply because they work!
The technique used is simple. Polarized lenses are designed specifically to reflect light in a way that it does not distort vision. Usually, when light waves strike a surface, such as water or metal, it reflects back in a particular direction (horizontally vertically or diagonally). This is called polarization.
Polarized lenses are laminated with vertical stripes that only allow vertically angled rays to pass through. This greatly helps vision and cuts down glare as no horizontal or diagonal lights are able to pass through the glass.
3D polarized glasses use a different technique than normal polarized glasses or lenses. In a 3D glass, two kinds of polarized lenses are used. There are two images (horizontal and vertical) formed on a 3D screen. Special 3D polarized glasses or lenses are designed to watch a 3D movie. One side is polarized vertically while the other is polarized horizontally so that the viewers are able to see both the images together. The brain is then able to put both the images properly and a three-dimensional image is formed.
Types
Polarized lenses are available in different degrees and at different discounted rates at various stores. Most inexpensive polarized lenses uses a thin film that is applied only on one side of the lens. Whereas, more expensive and high quality polarized lenses use two layers that further help improve vision. It also prevents the glass or lens from being stretched or rubbed off. In simple words, denser film provides more polarization.
