It is true
that human’s eye can accept some limited range of light and create image on the
retina. But, there are many animals and birds who can see in the night clearly.
However, all countries have competed to develop their technology into different
ways which help to reduce human efforts with high speed and with good accuracy.
Some scientists are trying to solve all problem through the technology. Still,
many people have problems. This essay will discuss on different situations happening
in the night and their solution through the technology. This issue presented about
problems while people driving their cars and also give a solution by
establishing the night vision systematic cameras which are using specially for
military purpose now. According to National Safety Council Research, there are
three times greater risk of fatal accidents occurred in the dark night because
of fog light comes from opposite vehicles.
there are two separate modes of visual perception-day vision and night vision.
Some people like to drive cars in the night because the ration of selling
vehicles is increasing with innovating new technologies which create traffic
problem. Now-a-days, traffic problem is one of the big issue. But other people
argued that it has a risk to drive at night compare to day time because there
are many factors affected in driving cars at night. For example, when we drive
a car in the night and fog lights directly come from other car in our eyes
which create blindness for few minutes at that time we cannot see anything.
Sometime Light of our car focus on only few areas of the road so, we
concentrate only on that areas. We cannot know what is happening besides the
road. Moreover, we all know that ages and night vision capability is
vice-versa. Older people have widely seen these night vision problems because
of retina. Retina have two types of light sensing receptor cells called rods
and cones. The rods can only see black and white and the cones can see in
detail but only in bright light said Stephen Ryan (2012). They are not sensible
and powerful in older people. However, when light reflects from the object and enters
in our eyes than after it creates an image through retina and we can see it.
