Polarised vs. Non Polarised. How does it work?
When horizontal light waves hit flat reflecting surfaces such as water, the human eye experiences a very harsh, dazzling flash known as glare, that can be both damaging and discomforting for the eye.
Polarised sunglasses have a built-in, laminated filter that only allows vertical light rays to pass through, and almost totally blocks horizontal rays. Even without glare, they selectively reduce other reflections from objects above water, including clouds and even the sky.
Non polarised lenses can bring a lot of UV protection to the table as well, but the main diference is that these lenses are designed at large to render view, regardless of the direction in which light falls onto a flat surface.
Ode to the polarised lense
Due to their certified benefits in reducing reflected bright light, and eliminating glare altogether, polarised sunglasses make for a real piece of machinery in the more complex geometry of light.
Originally popular among boaters and water sport athletes, interest for polarised sunglasses soars as more and more people realize the significant benefits of these smart lenses in the overall outdoor experience.
They’re perfect for driving, reducing glare from flat surfaces as the hood of the car or the road's surface and attenuate a good deal of the pesky bright reflections of the sun on the cars ahead. From professional athletes to outdoor enthusiasts like bikers, golfers or joggers, virtually everyone can enjoy the enhanced outdoor experience of councious sun exposure through polarised lenses.
Polarised sunglasses are by no means less lavish in design. They come in all shapes and shades - from light gray (only polarising) to very dark (polarising plus black tint), light sensitive (photochromatic) or even with user adaptale darkness.
