Nyctalopia, popularly called night blindness is an issue of the eye, it impairs your night vision and results in the victim's inability to see properly at night or in dim/low/poor light, the experience is nothing close to blissful and its impact is felt when you move from a bright environment to a dimly lit or dark room, the eyes of someone with night blindness will find it hard adjusting to dimly lit room.

The pupils of our eyes are constantly adjusting based on the intensity and brightness of the light we are exposed to, but with night blindness this is no longer possible because some damage has occurred with the rod cells (cells that enable us to see in the dark).

The mechanism of night blindness when closely looked at points to the fact that there are causes, night blindness won't just happen to anybody without a cause, three of those causes will be discussed below and ways to prevent this eye problem will be suggested. The causes of night blindness include;

1. Cataracts.

This is an eye problem that can lead to the problem at hand, night blindness, cataracts occur when the lens of the eye becomes clouded as we age, this is to say it happens gradually as we grow.

Considering the cloudiness that accompanies cataracts the amount of light that is let into the eye is reduced, this in turn causes visual issues in dim light (Night blindness).

2. Glaucoma (Glaucoma Medication).

A group of eye problems that lead to damage in the optic nerve that connects the eye to the brain thereby increasing the pressure in the eye and impairing peripheral vision is referred to as glaucoma, this eye issue needs to be treated in time to prevent permanent loss of vision.

Well, treatment of glaucoma includes the use of medication. This medication is said to constrict the pupil thereby allowing less light to get into the eyes and ultimately making the victim more open to night blindness.

3. Vitamin A Deficiency.

Deficiency of vitamin A has for long been identified as a cause of night blindness and it still is, vitamin A has a vital role in transforming nerve impulses into images in the retina, this goes to show how important vitamin A is to humans, vitamin A also promotes good eyesight especially in dim light (Source:

This goes to show that a deficiency of vitamin A can lead to night blindness, among other health issues.

Focusing more on foods to eat for the prevention of night blindness, I want to draw your attention to vitamin A (Retinol), this nutrient is beneficial for the prevention of night blindness and it takes care of eye health to its capacity.

Vitamin A-rich foods are to be incorporated into our diets and eaten adequately if we want to prevent night blindness, below are some food that can help prevent nyctalopia.

1. Sweet Potato.

Sweet potato being a rich source of beta-carotene is good for consumption if you want to prevent night blindness due to vitamin A deficiency as the body can convert beta-carotene to vitamin A.

2. Carrot.

Orange carrot contains beta-carotene just like sweet potato above, the same process of beta-carotene conversion to vitamin A takes place when we eat carrot, making vitamin A available to the body for usage, one of the uses is for better eye health and prevention of night blindness.

3. Milk.
