Why Your Vision Gets Worse 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 thereceptors 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.

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.

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.

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.
