Don't Be Blinded by Bright Lights
RIGHT lights from oncoming vehicles can cause many people distress. With more
and more vehicles now sporting fog lamps and other auxiliary lights, the problem
can only get worse. However, with the right strategies, right driving
techniques, and the right equipment you can deal with the glare bear.
Ideally, fog lamps cast a low, broad beam to reduce "back-scatter"
from the vehicle’s headlights when water droplets hang in the air. They’re
intended to improve a driver’s ability to see in foggy, misty, or hazy
conditions. However, when aimed improperly or used on clear nights, they can
annoy other drivers.
Some Tips to Follow
Avert your
eyes: When oncoming vehicles shine light directly into your eyes,
look down and to the right. Turn your gaze to the white line on the
right side of the road or to where the pavement meets the shoulder
until the vehicle goes by.
Use the
mirror’s "night" setting: Most cars have
"day/night" interior mirrors to reduce reflected glare
from vehicles directly behind. You can change the mirror to its
"night" setting by flipping the small lever at the bottom
of the mirror.
Use your
lights courteously: If your car has fog lamps, don’t use
them if there is no fog. In fog, use only your low-beam headlights.
High beams reduce your own ability to see and may temporarily blind
other drivers. Avoid using your high beams when you see oncoming
vehicles or when you drive in urban areas.
Take
frequent breaks: If you go on long trips at night, stop often to
reduce fatigue and give your eyes a chance to recover. Take a short
nap, or at least a brisk walk and some caffeine to help you stay
alert.
Anti-reflective
eyeglass coating: Many eye care specialists recommend glasses with
an anti-reflective (AR) coating. This ultra-thin film reduces
internal reflections in the lenses. Unlike sunglasses, which block
some light, AR-coated glasses actually transmit more light. This
improves vision at night.
Self-dimming
mirrors: Many cars now offer self-dimming mirrors that reduce
glare but allow you to maintain good rearward visibility. As the
glare becomes brighter, the mirrors become darker.

Then, of course, you have the high intensity discharge (HID) lights.
HIDs not only emit twice the light of halogen headlamps, but also produce a
blue-white light. Other headlights look yellow by comparison. Many motorists say
they find the amount of light produced by HIDs and its blue-white quality
blinding.
The increase in the number of four-wheel drive vehicles also presents a
problem. Many of these larger vehicles ride higher than cars. As a result, their
headlights ride higher, too. It’s no wonder that car drivers complain that the
lights on big 4X4s shine directly in their eyes.
Headlights pointed as little as one degree too high can make a huge
difference to drivers of oncoming vehicles.
Misaimed beams also don’t cast sufficient light on the road. Vehicles more
than five years old are twice as likely to have lights that are not pointing
correctly. Middle-aged and older drivers are more sensitive to glare because
their eyes take longer to adjust to changing light levels. Complaints about
glare are sure to rise as the population ages. Certain other conditions, such as
having had vision-correction surgery that affects the corneas, can also increase
sensitivity to glare.
You can help yourself beat the glare bear by taking the following steps:
Clean your headlights: When you have your windscreen cleaned at the
petrol station, be sure to also clean your headlights. Even a thin layer of road
grime on the headlight glass can severely restrict your ability to see at night.
Clean lenses are even more important if you have HID headlights. Dirt diffuses
the light from HIDs and causes glare that can temporarily blind other drivers.
Garage owners can help by urging staff to not only clean the windscreens, but
also the headlights.
Keep all glass clean: Streaks, smudges, and road grime on your
windows catch and refract light. This includes the inside of your windshield.
Chemicals from the plastic in your car’s interior slowly build up on the
glass. Scratched spectacles or contact lenses also make glare worse. Also clean
your wiper blades with a paper towel dipped in windshield washer fluid. Chips or
cracks on the windshield should be repaired immediately.
Aim your headlights correctly: Take your vehicle to a properly
equipped repair shop at least once a year for a headlight checkup. Your properly
aligned headlights will not only help you see the road better, but will also
help other drivers experience less glare.
Adjust both outside mirrors: Remember, properly aligned
mirrors not only reduce blind spots, they also reduce glare from vehicles behind
you. When vehicles pass you, the mirrors should not direct the brightest part of
the headlights into your eyes. When your mirrors are angled correctly, blind
spots are reduced. It becomes easier to see approaching vehicles on the side and
rear.
Have your eyes checked: Everyone, irrespective of their age, should
have their eyes checked regularly. But also bear in mind that age makes eyes
more sensitive to glare, and that cataracts increase the problem.
