What is a Polarised Lens?
Polarised lenses are laminated with tiny vertical stripes that only allow vertically angled light to enter the wearer's eyes. Glare is eliminated because the horizontal light waves cannot bypass the vertical filter.
Sunglasses and camera lenses are often polarised to reduce glare from surfaces, such as light reflecting off a lake or the bonnet of a car.
How Polarized Lenses Work?
Polarized lenses have a special chemical applied to them to filter light. The chemical's molecules are lined up specifically to block some of the light from passing through the lens. Think of it like a miniblind hanging in front of a window. Only light that passes through the blind's openings can be seen.
On polarized sunglasses, the filter creates vertical openings for light. Only light rays that approach your eyes vertically can fit through those openings. The lenses block all the horizontal light waves bouncing off a smooth pond or a shiny car hood, for instance.
As a result of this filtering, the image you see with polarized lenses is a bit darker than usual. But objects look crisper and clearer with polarized lenses, and details are easier to see.

When to Use Polarized Glasses?
People who use polarized sunglasses often say they are less tired than usual after hours of battling sun glare. Polarized sunglasses can be a good choice for most everyday situations. These are some specific situations when polarized sunglasses may be especially helpful:
1. Fishing. People who fish find that polarized sunglasses drastically cut the glare and help them see
into the water.
2. Boating. A long day on the water can cause eyestrain. You may also see below the surface of the water better, which is important if you are driving a boat as well.
3. Golfing. Some golfers feel that polarized lenses make it hard to read greens well when putting, but studies haven't all agreed on this issue. Many golfers do find that polarized lenses reduce glare on fairways, and you can remove polarized sunglasses when putting if that's your preference. Another benefit? Though this would never happen to you, golf balls that find their way into water hazards are easier to spot when wearing polarized lenses.
4. Most snowy environments. Snow causes glare, so a pair of polarized sunglasses are usually a good choice.
