Night blindness causes

We will discuss the problem called night blindness and how this problem is treated. This is a problem that causes inability to see in dark lightening surrounding. This problem is also called nyctalopia, which leads to the inability to detect images and shapes in low lightening conditions. Night blindness can be very dangerous if a person walks or drives during the night.

Causes

The severity of the condition is influenced by several factors so there are many causes of the problem. One of the causes is deficiency of vitamin A, which is a problem that can lead to dry eye and disorders associated with the retina. Cataract can also lead to night blindness, which is a condition associated with cloudy eye lens. Visual problems may be experienced due to this condition, which can be present during the night and day as well, but the problem will be greater during the night. We need to adjust when we transfer from high to low light condition and inability to do this can lead to night blindness. The condition in question can also be developed due to birth defects and use of some medications. Retinal pigmentosa and other forms of retinal degeneration problems may be accompanied by night blindness. Risk of suffering from night blindness can be increased due to several factors. So, those who consume low amounts of vitamin A, who are old or had retinal degeneration conditions in the family, have increased chances of developing night blindness. The inability to properly absorb vitamin A can be a sign of several health conditions, and this leads to the deficiency of this vitamin and eventually to night blindness. This inability is more likely to happen in those with intestinal problems, liver disorders and those who underwent surgery on liver or pancreas.

Loss of vision can accompany night blindness and this is a problem that usually occurs during the day. Gritty emotion in the eyes, dry feeling in the eyes, inability to distinguish shapes in dark soundings, double and blurred vision are the most common symptoms of night blindness.

Treatment

The cause of the problem determines the course of the treatment, but vitamins are the most common and simple way of treating this problem. If you are having a vitamin A deficiency, taking this vitamin will eliminate this problem and night vision. The results will not develop instantly; it may need several weeks and months, but it will occur. Removing cataract is the solution if this problem is present. This will eliminate night vision and cataract. The treatment of those with retinal degeneration or birth defects depends on many factors, so every case is different. Timely response and visit to the doctor improves the chances of slowing down the development of the condition. Patients may even recover from the condition in some cases. But it is important to be careful during the night if you are having a problem with night blindness. Try to avoid driving during the night and falling due to disorientation.
