Polarized lenses reduce glare from reflective surfaces. They accomplish this
feat through a process called polarization. Much like a venetian blind controls
sunlight through a window, polarized lenses control or polarize the light
passing through a lens before it reaches your eye. The most common sources
of visual glare are surfaces like water, pavement, or the hood of a car.
Fishermen have appreciated polarized lenses for decades because it takes
the blinding glare of the water’s surface away and provide better vision into
the water. Drivers are no longer affected by a constant reflection of light from
their hoods or the road ahead.
There are some limitations to the use of polarized lenses. Because
polarization reduces the amount of light entering the eye, polarized lenses
cannot be used for regular eyewear with clear lenses. Some wearers
discover that polarized lenses can cause distortions in liquid crystal displays
(LCDs). Onboard clocks and other instrument displays may be temporarily
unreadable. Since polarized lenses do not provide universal protection from
glare, an anti-reflective coating may be needed to minimize glare.
