Why your Vision gets Worst at Night

If you need a nightlight to find your way to the kitchen for a
midnight snack, or have difficulty seeing while driving in the
evening, you may be suffering from a condition known as "night
blindness."

Unlike animals, human vision is generally not as keen at night.
Cats, for instance, see well at night because they have more rods
than cones in their retinas, unlike humans. (Rods are the
receptors that the eye uses for nighttime vision.)

It is estimated that most people take about 20 minutes to see
adequately in the dark. This time allows your eyes to adjust
from the brightness of daylight or indoor lights. As the light
dims, your pupils dilate (grow larger) to take in more light.

But your dilated pupils reduce your ability to change your focus
between near and far objects, so if you are driving, say, you may
be "blinded" by streetlights and oncoming headlights. Your pupils
constrict to block out the lights, but once those have passed,
they must dilate to readjust to the dark, making it difficult to
see the road.

Unlike a cat's, human pupils simply can't adjust
fast enough to keep up with the cycle of light and dark.

One of the most common causes of night blindness is deterioration
due to age. In the natural aging process, the eye lens becomes
less clear and grows cloudy over time, making it difficult to see
in dim light. It is estimated that seniors need up to 50% more
light to see clearly.

Another general cause is uncorrected myopia, or nearsightedness.
Even with vision correction, nearsighted people may find their
nearsightedness is exacerbated when their pupils dilate at night.

Essential Tip #1

Vitamin A supplements are often recommended for those with poor
night vision, along with a diet emphasizing Vitamin A-rich foods,
such as sweet potatoes, carrots, mangoes, spinach and cantaloupe.

Essential Tip #2
=================

Bilberry is also thought to improve night vision. A close relative
of the blueberry, bilberry is high in a certain type of
bioflavonoid that speeds the regeneration of rhodopsin, the purple
pigment used by the eyes' rods.

Essential Tip #3

Keep your car windshield and car windows clean-inside and out.
Having dirt and debris on your windshield makes it harder to see
and exacerbate glare, especially at night.
