Inability to see well at night or in poor illumination is called chicken blindness (nyctalopia). This condition can be a symptom of some underlying disease, as well as a sign of nutrient deficiency.

The causes of vision impairment at dusk and in the dark were discussed by experts at the Cleveland Clinic.

Myopia

Myopia can make it difficult to see well at long distances in the dark, especially if the person does not have the appropriate glasses or contact lenses. In this case, a new prescription may be enough to solve the problem.

Some medicines

Some medications can also cause temporary problems with night vision. Sometimes the drugs change the size of the pupils, which makes it difficult to see in low light conditions. There are also medications that slow down the ability of the eyes to adapt from bright to dim light.

Cataracts

Cataracts are clouding of the lens of the eye. This condition is another cause of night vision problems. As cataracts form, less light enters the eye, which means a person needs more light to see. People with cataracts often complain of difficulty driving at night and in the rain, of being dazzled by the headlights of oncoming cars.

Nutrient deficiency

Reduce the ability to see in darkness can be a deficiency of vitamin A. The level of the vitamin is checked with a blood test, vision problems can be reversible when the deficiency is filled. Adding foods rich in vitamin A, such as carrots, dairy products, or mackerel, can help restore night vision.

Retinitis pigmentosa

This is one of several hereditary diseases that cause problems with night vision. Retinitis pigmentosa leads to deterioration of the retina, which is the part of the eye that perceives light.
