It is true that if there is life, there will be problems and diseases. Because, human life is full of challenges, mental stress, mistakes and physical suffering. There are many such problems which are difficult to understand. Sudden darkness before the eyes is one of such problems. It is often seen that sometimes while walking or waking up suddenly, we feel that everything in front of us starts becoming blurry or dark. This experience is as scary as it is shocking. It disappears within a few seconds, but sometimes it happens so suddenly that the person does not understand what is happening to him. Now the question is why suddenly there is darkness before the eyes? What are its scientific reasons? Let us know-
Why does darkness suddenly appear before the eyes?
There can be many reasons behind sudden darkness before the eyes. One of the most common causes is ‘orthostatic hypotension’, when we sit or lie down for a long time and suddenly stand up, the blood pressure in the body does not immediately reach normal levels. In such a situation, when blood reaches the brain less, there is darkness in front of the eyes, the head spins and sometimes dizziness occurs.
Temporary unconsciousness may also occur in this situation
If it continues for a long time, temporary unconsciousness may also occur. This condition is often seen even in healthy people, especially after long runs in summer or if you do not drink water for a long time. An easy way to prevent this is to slowly stretch the body and take a deep breath before standing up.
This problem can occur in this situation
Apart from this, migraine can also be a reason for darkness in front of the eyes. The effect of migraine is not limited to headache only. Many people experience flashing lines, flashes or temporary darkness before the eyes before a migraine starts. This usually lasts for a few minutes and then normal vision gradually returns.
In some cases, this may also be a sign of a serious problem. A transient ischemic attack (mini-stroke) temporarily stops blood flow to the brain. During this, weakness, numbness or difficulty in speaking may be felt in any part of the body. If treatment is not received on time, the problem can become big.
Another serious condition is retinal detachment. In this the retina of the eye starts moving from its place. Suddenly one may experience floaters in front of the eyes, bright lights or a curtain falling on one side. This is an emergency condition, because if not treated on time, vision can be permanently affected.
