Millions of People all over the world experience night
blindness, which could be a sign of something more serious to come. If your
vision is normal during the day, but you struggle to see clearly at night or
experience complete night blindness, in some cases the conditions are easily
treated or it could be a serious condition like a congenital condition such as
retinitis pigmentosa or a symptom of a condition that is not directly related
to the eye.
Night vision trouble can crop up in those individuals who are
always in the sun exposing their eyes to long durations of UV exposure. It
could also be a sign of a vitamin A or zinc deficiency or cataracts to say the
least.
What Causes Poor Night
Vision?
Difficulty with night vision can stem from conditions ranging
from exposure to the sun and vitamin deficiencies to a chronic disease such
as cataracts.
Vitamin A deficiency
– We have all heard the common “Old Wives Tale” of carrots being good for the
eyes. This is in fact as true as it gets. Carrots contain vital vitamin A,
which helps keep the retina healthy. Vitamin A is also found in many greens
leafy vegetables and yellow vegetables. Night blindness caused by vitamin A
deficiency is very rare in developed countries as diets are diverse and
nutritious. This mostly happens in those people who have trouble absorbing
nutrients and is therefore a secondary symptom various other conditions like
Crohn’s Disease, celiac disease, cystic fibrosis, and pancreatic insufficient.
Cataracts - The
first symptoms of cataracts is night blindness. Cataracts is associated with
the lens, the part of the eye that is responsible for regulating light. In
reduced light intensity, the cloudy lens struggles to see clearly and some
people experience blurry vision, while others are affected with complete night
blindness as the cloudiness progresses to severe stages.
Zinc- this mineral
assists vitamin A to be used in the eye. Without zinc, vitamin A is unable to
be utilized correctly. Zinc deficiency is a rare phenomenon as it found in abundance
in meat, poultry, nuts, beans, and other popular foods. Zinc deficiency is
caused by the same bodily conditions as with Vitamin A.
Diabetes night vision
problems – high amounts of sugar in the blood stream is toxic and damages
blood vessels. The retina, which is the part of the eye that has images focused
on it, has many blood vessels flowing through it for nourishment and oxygen
supply. These blood vessels can swell and burst, leading to night vision
problems.
Sun exposure – if
you have recently taken a trip to the desert of the beach and are having
trouble seeing at night, this condition is only temporary and will probably
resolve itself within two days. To avoid UV damage, doctors recommend wearing
sunglasses at all times when outdoors on a sunny day.
Retinitis Pigmentosa -
is a rare genetic disorder which affects people before the age of 30. The
condition is noted by worsening night vision and day vision, although some part
of your vision will still remain.
Eye Surgery – Lasik
Eye Surgery patients also experience mild to severe light sensitivity which can
last a few days to a week after surgery. Eye doctors will perform many tests to
identify individuals who are at risk for developing the condition and recommend
other treatments for those individuals, although the risk of having night
vision trouble is still real.
