Retina has two types of photoreceptors cone cells and rod cells. Cone cells are
responsible for colour vision and work in bright lights, whereas rods work in dim lights and
they are present in the periphery of the retina. Rod cells are very important at night for vision.
Night blindness mainly is caused due to Retinitis pigmentosa and conginetal. It is also
caused due to retinol (vitamin A) deficiency which is very rare and can be treated retina
Retinitis pigmentosa is the condition in which the rod cells in the retina gradually
loose their ability to respond to the light, people with this condition experience night
blindness and eventually their daytime vision may also be affected.
In x linked congenital disorder night blindness is observed since birth and it stays life
long. In this condition the rods do not work properly or do not work at all. There is no
treatment for this condition, it stays and doesn’t become worse either

How to Prevent Harm Due to Night Blindness
According to the Council of National Safety (NSC), death rates in the traffic is three times
greater at night time than compare day. Driving at night time is more dangerous because a
driver’s capacity to react depends on vision, & healthy vision has severely restricted at night.
Older drivers have even higher difficulty seeing during night time. A fifty-year-old driver
will require twice as much light to see c thirty-year-old.
The best method to protect yourself from harm due to night blindness is to bypass driving
during night time and drive only at the day time. People with night blindness can have trouble
in driving even in a well-lit city. If you need to go out at night, you have to take steps to
protect yourself. Improve your visibility by washing your car windows & headlights, & slow
down to give yourself more time to respond to any unanticipated hazards.
