When you are on a trip to see the natural wonders or beautiful beach landscapes, you may suffer the reflective glare that makes you temporarily blinded to the beauty of nature. Direct exposure to blinding glare may lead to annoyance and eyestrain. Thanks to polarized technology, polarized lenses can block out glare and bring a sharp vision for the glass wearers.

How polarized lenses work?

Natural sunlight from the sun reflects in many directions depends on the subjects it encounters, and it scatters everywhere around us. It becomes polarized right after reflecting from the flat surfaces like a river, a lake. Polarization is a process to transform the physical property from sunlight waves to vertical and horizontal waves. Vertically light waves are beneficial to your eyes, but horizontally light waves are known as glare to cause discomfort and poor visibility.

A thin chemical filter added to lenses makes them capable of filtering the sunlight. Molecules from a chemical filter are lined up to create vertical openings, very much like window blinds. Polarized lenses function as a smart door blocking annoying glare while allowing the vertically light wave to pass through. As a result, the glass wearers will experience comfort and clear and sharp images.

When you need polarized sunglasses:

Fishing & boating - Anglers and Boaters can see fish or objects beneath water surfaces.

Driving - Blinding glare reflected from the road surface hits directly to your eyes may cause a temporary loss of visibility. The inability to see oncoming traffic due to glare is incredibly dangerous.

Water sport – water is a very reflective place that creates intense glare and discomfort. Polarized lenses help water sports enthusiasts to obtain a clear vision for better performance.

Beach sightseeing - beach Tourists can enjoy beautiful beach landscapes without interfering with a glare.

When not to use polarized sunglasses:

Polarized lenses have practical advantages over UV lenses, but for some situations in which polarized shades are not appropriate to wear.

Operating LCD machine - it's challenging for a machine operator to read instructions on a liquid crystal display.

Skiing - ice and snow colors are the same when viewed through polarized lenses. That means polarized lenses can not tell differences between dangerous ice and snow. In this situation, reflective glare is helpful to help Skiiers to avoid dangerous places.
