Change your view with polarized sunglasses

What are polarized sunglasses?

Polarized sunglasses consist of tinted lenses with a chemical filter applied to the lens surfaces to block blinding glare from water or flat objects. Glare is the temporary loss of vision caused by excessive light striking into the eyes that are over an ability the eyes can manage. In the short term, glare causes eyestrain, headache, blurring vision, and color distortion. Prolong exposure to glare may lead to eye diseases as cataracts, macular degeneration. These phenomena happen when you are wearing UV sunglasses which are designed to block solar radiation only, with nothing to do with glaree. On the contrary, besides providing complete UV protection, polarized sunglasses can block annoying glare to enhance your vision inwet roadss or water environments.

How is glare created?

Natural light from the sun is present everywhere around us, even on overcast days. When it encounters a smooth object, it becomes polarization in which natural light transforms into vertical light and horizontal light. Vertical light is not harmful, but horizontal light is known as a glare to reduce visibility and cause eyestrain. Polarized lenses have a chemical filter applied to the lens surfaces. This chemical filter acts as a smart gate to let the beneficial light go through while blocking harmful glare. Thus when wearing polarized shades, you will experience comfort, better visibility, and true color perception.

Benefits of wearing polarized lenses

• Driving: help reduce glare and hallucinations. Hence drivers see the road clearly and safely drive.
• Outdoor sports: reduce eyestrain, improve visual clarity. Hence sports enthusiasts can maximize performance.
• Fishing: help anglers see above and beyond the water surface, even the fish hiding underneath the water.
• Beach sightseeing: help beach tourists enjoy the beauty of the beach landscape without eyestrain.

Disadvantages of wearing polarized lenses

• Polarized lenses have the same polarizing technique as liquid crystal displays. Thus you can not wear polarized shades to read instructions from LCD.
• When viewed through polarized lenses, the snow and the ice have the same white color. That means skiers can not notice which place is dangerous to avoid an accident.

How to identify polarized sunglasses?

• Check the letter "P" printed on the sunglass lenses.
• Check the word " polarized" printed on the left temple.
• Use a polarized tester. The blurred image on the polarized tester becomes clear and sharp when viewed through polarized sunglasses.
• Using a computer screen or your phone: place your shades in front of the computer screen with direction appear as you are wearing them. The image on your lenses will turn darker when you turn your glasses 90 degrees.
