Jun 27, 2019 · How do polarised lenses work? Sunlight scatters in all directions. But when it strikes flat surfaces, the light that is reflected by the surfaces tends to become polarised — meaning the reflected light beams travel in a more uniform (usually horizontal) direction.

What are polarised sunglasses?
Put simply, polarised sunglasses are designed to reduce glare from light-reflecting surfaces like water, glass or snow – as well as protect your eyes from harmful UV rays. Standard sunglasses will protect your eyes from bright light, and in most cases, offer UV protection — but they aren’t always able to reduce glare.

Light travels from one place to another as a wave. In some ways, it is like a wave on a lake. Light travels out in all directions from a source, much like a water wave travels away from a rock dropped into water. In a wave on a lake, the water moves up and down while the wave travels across the surface perpendicular2to the motion of the water. A li...
To understand polarisation, picture a wave on a rope. If you make a series of up and down motions while holding onto a rope, a series of waves will move from your hand along the rope, transferring the motion down the rope. The rope moves up and down while the wave (and its energy) travels along the rope perpendicular to the motion of your hand. You...
One method of polarisation is by the use of a special polarising filter or lens. To understand how a polarising lens works, let’s go back to our rope example. If you make vertical waves on a rope that go through a vertical slit, shown as in figure A in the image below, the waves would travel through the slit easily because the orientation of the sl...
You can find examples of polarised light3in many places. When light is reflected off a surface at a steep angle, such as sunlight off the surface of water or an automobile windscreen, it becomes polarised. The glare from such reflections is greatly reduced by polarised lenses in sunglasses. The glasses worn by the audience in modern 3D films are po...
Apr 12, 2024 · Polarised sunglasses are like having a secret super power. They drastically improve clarity, block glare, enhance your colour perception and even improve eye comfort. But when they look just like regular sunglasses, how do you know if they're actually polarised? This article provides two tried-and-tested methods to sho
Nov 25, 2022 · What does polarisation mean and what do polarised sunglasses do? A polarising filter is something every photographer is familiar with. It increases contrast and decreases reflections.
Jan 24, 2024 · Unlike standard sunglasses, polarised sunglasses are laminated with tiny vertical stripes that only allow vertically angled light to enter the eyes. By wearing polarised sunglasses, glare is eliminated almost immediately as the light waves cannot bypass the vertical filter.
But have you ever wondered how polarised sunglasses work? In this article, we delve into the science behind polarised sunglasses and explore why iPOP Polarised sunglasses are a must-have accessory for anyone seeking optimal eye protection.
