Polarization is a phenomenon caused due to the wave nature of electromagnetic
radiation. Sunlight is an electromagnetic wave that crosses)the vacuum to reach the earth since
they form when an electric field interacts with a magnetic field. A polarizing filter modifies
reflected light to provide a cleaner, higher-contrast image by removing light that has been
reflected in the scene.
Automobiles windshields are made of special tempered glass to maximize the visibility
of drivers, polarising the windshield can have an impeccable help during day time as it will
reduce some lights that enters to the vehicle, the glare from the sun or the headlights can be
blinding. This causes terrible irritation to one’s eyes. To see better and eliminate the discomfort
caused by the reflection and deflection of light, some drivers choose to polarizer on their car
windshields. Note that car windshields are made of two strong glass layers which many refer to
as laminated glass and already comes with low level of polarization. Thus owners wants to install
higher level of polarizer to their vehicle to with stand a weather hotter than usual which can
result serious accident. During night driving this scheme will fail, even to reduce the glare, the
intensity of oncoming light is reduced this may do more harm than good. The filter placed on
polarized windshields prevents some light from hitting the eye, so it creates a dimmer view
inside the vehicle.)Blocking additional light from an already low-light condition can inhibit your
vision even more so than the glare of traffic lights.)polarizing your windshield can distort how
light travels through your car windshield.)Thus, you may not see other cars or objects deflecting
light until it’s too late.)A polarizing filter used to reduce the glare, and this glare is produced by a
horizontal light therefore polarizing filters should be arranged to block the horizontal light and to
pass the vertical light only so polarizing axes must be arrange horizontally, always remember
that when polarizing axes of the two filters are aligned the intensity of light is greater but when
the polarizing axes are perpendicular the intensity is zero, no light will come to your vision. In
generalization if you want to have a polarizer windshield the angle of the filter of the glass
cannot be 0 or 90 degrees so that you can achieve a good vision anytime of the day.
