Night blindness is also called nyctalopia. It's a type of vision impairment. People with night blindness experience poor vision at night or in dimly lit environments. It is not a disease in itself, but rather a symptom of an underlying problem, usually a retina problem.
What Causes Night Blindness?
A number of eye conditions can cause night blindness, including:
- Nearsightedness or blurred vision when looking at faraway objects.
- Cataracts or clouding of the eye's lens.
- Retinitis pigmentosa, which occurs when dark pigment collects in your retina and creates tunnel vision.
- Vitamin A Deficiency
- Zinc Deficiency
- Dry Eyes
Are the Symptoms of Night Blindness?
The sole symptom of night blindness is difficulty seeing in the dark. You're more likely to experience night blindness when your eyes transition from a bright environment to an area of low light, such as when you leave a sunny sidewalk to enter a dimly lit restaurant. You're likely to experience poor vision when driving due to the intermittent brightness of headlights and streetlights on the road.
How can I Prevent Night Blindness?
You can't prevent night blindness that's the result of birth defects or genetic conditions, such as Usher syndrome. You can, however, properly monitor your blood sugar level and eat a balanced diet to make night blindness less likely.
Orange colored foods are excellent sources of vitamin A, including:
- Sweet potatoes
- Butternut squash
What are the Treatment Options for Night Blindness?
The treatment will depend on its causes.
- Nutrient deficiency (Vitamin A and Zinc) is the easiest to treat.
- If the cause is cataract, you can go for cataract surgery to remove the clouded lens and replace it with artificial intraocular lens. Vision is usually dramatically improved after surgery.
- For dry eye syndrome, lubricate your eyes with artificial tear drops as they provide instant relief. Just make sure that they are without preservatives.
- Diabetic retinopathy can be prevented with tight control over blood sugar, active lifestyle and good dietary habits.
- As for retinitis pigmentosa, unfortunately there are no treatments available. Thankfully, new research is showing that vitamin A might have a slowing effect on the progression of this eye disease. If you wish to discuss about any specific problem, you can consult an ophthalmologist.

Myopia is also known by the name of nearsightedness. It is one of the most common refractive disorders of the eye. Over the years, it has become more prevalent. According to a recent study conducted by the National Eye Institute (NEI), myopia has grown more prevalent from 25 percent in 1972 to around 40% percent in 2004 in United States.
The exact cause of the prevalence of this disorder in USA is not known. However, many doctors are of the opinion that eye fatigue due to overuse of computers can be the primary reason behind the spread of this disorder. It could also be affected by genetical links.
Myopia Symptoms And Signs:
It is time to take care of your eyes if you have difficulty in reading the sign boards on road or seeing objects from a distance. This could be a sign for myopia if you are able to see things clearly from a closer distance. There are several symptoms of myopia, including strain on eyes, headaches and squinting. If these signs don’t vanish after wearing lenses or spectacles, you must consult an ophthalmologist.
What are the factors that cause Myopia or Nearsightedness?
It occurs at a time when the eyeball of the patient is too long. The lens of the patient will be too long as compared to the focusing power of the cornea or the eye lens. This condition leads to the focusing of light rays at a point in front of the retina. The rays don’t focus directly on the retina’s surface. Myopia can also be caused if the lens of the eye is too curved. Myopia can also be caused due to a combination of factors. The problem may start from childhood. You are also at the risk of developing the problem if your parents have had the problem.
Myopia is not a rare disorder of the eye. People living with myopia have several options of its treatment. It can be rectified or corrected with the help of spectacles and contact lenses. It can also be corrected by refractive surgery. The kind of treatment to be chosen depends upon the degree of your myopia. You will be asked to wear lenses or spectacles for a prescribed amount of time, depending upon the degree of your disorder.
If you are suffering from myopia, the doctor will prescribe you to wear spectacles or lenses of a certain power that will be preceded by a minus (-) sign.
