Why Does My Vision Get Worse at Night?

Why Does My Vision Get 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.

People with night blindness see poorly in darkness or dim light but normally when adequate amounts of light are present. The condition is not the nighttime equivalent of true blindness-nonetheless, those who have it know how limiting its effects can be.

Seeing in the Dark

It is estimated that most individuals 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.

However, a dilated pupil reduces your ability to change your focus between near and far objects, so that, for instance, while driving you may be “blinded” by streetlights and oncoming headlights. Just as it takes a while for your eyes to adjust when you enter a dark room, it also takes time for your eyes to adjust when a headlight appears. If you focus on the headlights, your pupils will constrict to block out the light.

Then, once the headlights have passed, your eyes will take time to readjust to the dark, making it difficult to see the road. In heavy traffic, your pupils may never adjust, as your gaze must constantly alternate between light and dark. Many people try to avoid this by attempting to look slightly away from oncoming headlights. This may help for a short time, but in the end you may have to avoid driving at night to prevent an accident.

Eye of the Tiger

Human beings are not like tigers, or housecats for that matter, whose eyes are superbly well adapted to seeing in the dark. One reason is that cats have more rods than cones in their retinas, unlike humans, making kitty night and motion vision superior. (Rods are the receptors that the eye uses for nighttime viewing and sudden movement. Cones are used during the daytime and process color information.)

Focusing up close is not natural to your eyes. As the human eye was not developed to spend all day focusing on computers, books, television, etc., doing so causes near-point stress, which contributes to the weakening of your vision.

Similarly, human vision is naturally poorer at night, when our hunter-gatherer ancestors were, presumably, sleeping (and perhaps guarding against tiger attacks). This is why the military developed night-vision goggles and scopes for soldiers. That said, if you are having great difficulty seeing in the dark, you are most likely experiencing night blindness.

Causes of Night Blindness

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.

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.

In some cases, night blindness is a symptom of a serious underlying condition, such as retinitis pigmentosa, which is inherited. This degenerative retinal disorder causes the retina’s rod cells-which, as we mentioned above, distinguish light from dark-to deteriorate and eventually stop functioning. Night blindness is often the first symptom of a cataract, as well. Early cataract development increases glare and decreases the amount of light reaching the back of the eye.

A Feast for the Eyes

Night blindness may also be caused by a Vitamin A deficiency. Supplements of that vitamin 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. British air force pilots in World War II ate bilberry jam to improve their night vision during evening sorties.

The Rebuild Your Vision Ocu-Plus Formula contains both Vitamin A and Bilberry. (Right now we are running a special for 1st time customers to receive a complimentary bottle)

Night Blindness Tips

  1. If you are still wearing your glasses, choose glasses with an anti-reflective coating to reduce glare.
  2. Keep glasses-including sunglasses-clean. Having dirt on the inside or outside of your lenses can disturb the filtering of light and scatter it, making it more difficult to see and increasing an already existing vision problem.
  3. Keep your car windshield and car windows clean-inside and out. Having dirt and debris on your windshield makes it harder to see, especially at night.
  4. While driving at night, avoid looking at oncoming car lights head-on; instead, try to look to the side of the lights in order to minimize glare. If your night vision is really poor, you may want to avoid driving at night altogether.

Don’t take chances with your life or the lives of those you love by continuing to drive if your night vision is getting worse.

While changes in diet may help some people suffering from night blindness it is always best to talk to a medical professional before adding a vitamin or supplement to your daily routine. If your night blindness has developed as you age, eye vitamins may help to restore some of the flexibility to your vision. In either case you should speak with your eye doctor or medical professional first.

About Orlin Sorensen

My vision started to get blurry as a young teenager. Soon I was wearing glasses for just about everything. This was a hard blow for me because I had always dreamed of becoming a U.S. Navy fighter pilot which required perfect vision without glasses or surgery. But I wasn't ready to give up on my dreams, so I looked into every possible alternative which led me to eye exercises. Through daily vision training and eye exercises, I improved my vision from 20/85 to 20/20 and passed the Navy's visual acuity test. In fact Men's Health declared this one of the "Greatest Comebacks of All Time!" Now, I'm sharing exactly how I did it with the program that helped me so people like you can improve your vision safely and naturally, without glasses, contacts or laser surgery.

    All of our supplements are only offered exclusively through our website. We don’t sell them in pharmacies as we don’t want to involve a distributor. Involving a distributor would only add costs to our vitamins and we do everything possible to save you money.

    As far as shipping goes, we ship all over the world and ship to the United Arab Emirates on a daily basis.

    Hi Orlin,
    I have -10 in both eyes and have had retinal detachments in both of my eyes. As I am only 39 years old I am very concerned about my future vision. Are you aware of any prevention options to avoid future retinal detachments in someone who has had them already – I find when I do high impact exercise or anything where I have my head down for a long time (vacuuming, washing floors or gardening) that I get some light flickers in my eyes for a while after but they do go away. Appreciate any information or guidance you have. Thank you.

  7. Hi Lisa,

    As far as avoiding future retinal damage, I would highly recommend talking with your eye doctor as he will know your specific case very well.

    To your vision — for life,

    Orlin
