Symptom in the eyes darkens. Why does it often get dark in the eyes?

Darkening in the eyes is an extremely uncomfortable and unpleasant phenomenon. It can take a person by surprise at any moment. Unfortunately, everyone has encountered this phenomenon at least once in their life. But in some cases, darkening can occur with enviable regularity. What to do and how to behave if your vision often gets dark? What are the reasons for such an unpleasant phenomenon? How to deal with this?

It often becomes dark in the eyes

Main causes not related to disease

The patient may not have any problems with the vascular system, regular frequent dizziness and any problems with the condition of the body and health, but he may still encounter such a phenomenon as a sharp darkening before the eyes, a feeling of weakness will appear, it may feel short-term but severe impairment of visual function. And sometimes this phenomenon is very frightening - most people immediately plan a visit to the doctor to understand what caused the sudden appearance of “darkness” and unpleasant “floaters” before their eyes.

Black spots before eyes

And sometimes people run to an ophthalmologist, although they have never had problems with their eyes before. But an ophthalmologist may not provide the necessary help, since for the most part such unpleasant phenomena do not appear due to reasons directly related to the eyes. Let's look at some of them.

The eyes may become dark for various reasons.

On a note! Doctors scientifically call this condition orthostatic hypotension. It is due to the fact that for some reason the blood did not reach the brain in sufficient quantities - it begins to experience a nutritional deficiency.

Hypotension

So, the reasons that are not related to health, but can cause darkening in the eyes, are the following.

1. Severe lack of fluid in the body . A person should drink at least 2 liters of water every day. If this rule is not followed, the body begins to experience a lack of fluid.
2. Nutritional features - these include mono-diets, fasting, a low-carbohydrate diet, etc. In this case, the body reacts to a lack of some nutrients.
3. Changes that occur in the body due to age. Darkening can be experienced by teenagers, older people, and women in menopause.

   
   Age-related changes are one of the possible reasons

4. Nervous shock or any effect on the body.
5. Bad habits also provoke darkening . Both smoking and excessive alcohol consumption do not maintain the body in proper condition, but only kill it. They negatively affect the condition of the body.
6. Use of a number of medications , such as sedatives, diuretics, as well as drugs that act on blood vessels, dilating them.
7. Sometimes pregnant women can also get dark before their eyes. This usually happens in the first months of pregnancy.

   
   Pregnancy is one of the possible reasons

8. Overwork - both physical and psychological or emotional . Typically, darkening occurs as a result of lack of rest for a long time. In this case, the person complains of poor sleep or other similar problems.
9. Serious and unusual physical activity , unusual for the body, sudden lifting of the body, prolonged standing in one place in a room with a lack of oxygen, etc.
10. Taking a flight - the pressure changes that the body experiences inside the plane can also provoke the appearance of darkness in the eyes.

Pregnancy and air travel

On a note! Darkening of the eyes can also be accompanied by such phenomena as headaches and dizziness.

Frequent and sudden darkening of the eyes

When a patient experiences frequent and sudden darkening of the eyes, the first thing to check is the completeness of the blood supply to the brain. For this purpose, you should contact a specialist who will prescribe a series of studies and tests. As a rule, this diagnosis reveals low hemoglobin, which causes dizziness, ripples in the eyes and darkening. As one of the treatment methods, the doctor will prescribe drugs with a high iron content and vitamin complexes.

Another problem with similar manifestations may be disturbances in the cardiovascular system and the general condition of the body and health. In this condition, the patient may feel general weakness, sudden darkening of the eyes, and vision problems, but all this goes away in a short period.

Causes associated with pathologies

Darkness in the eyes can occur not only as a result of the above. In some cases, certain diseases can provoke this phenomenon. If darkening is observed regularly, then it makes sense to visit a doctor and undergo an examination. Most likely, this symptom was provoked by the development of some pathology, which is not always conditionally safe.

If you experience regular darkening in your eyes, you should consult a doctor.

It is especially important to consult a doctor as quickly as possible if the patient has other serious symptoms, including seizures and regular migraines.

Table. Some causes of darkening.

Bradycardia - abnormal heart contractions

Attention! Dysfunction of the vitreous body of the eye can also provoke frequent darkening. In this case, the person also complains of dizziness and generally worsening vision.

Hypotension

Let's take a closer look at some diseases that cause darkening of the eyes. So, hypotension is one of them, which occurs quite often and is associated with a decrease in blood pressure. There are several types of this disease, depending on the cause of low blood pressure:

• congenital hypotension;
• medicinal;
• orthostatic;
• physiological.

Hypotension

Thus, low blood pressure can be caused by hereditary factors, stress, medications, and also occurs as a result of a number of factors affecting the body (physical activity, pregnancy, etc.). In some cases, hypotension accompanies a person throughout his life, and may occur against the background of other pathologies.

With hypotension, a person experiences fatigue and drowsiness, complains of migraines, etc. Darkening is also a fairly common result of decreased blood pressure.

Symptoms of hypotension

Orthostatic hypotension is the same type of pathology when a person’s vision becomes dark. Typically, the phenomenon occurs if the patient suddenly moves to a vertical position from a horizontal position or suddenly rises from a squatting position. In this case, darkening and faintness occur very suddenly. If a person does not find support for himself, he may fall. The condition is short-term and lasts only 3-5 minutes, but the pressure during this period decreases extremely significantly.

Treatment

Treatment directly depends on the cause of the darkening. Therefore, it is necessary to divide it into drug and homeopathic treatment. Both types of treatment will be effective. The main thing is to correctly identify the disease.

Drug treatment

You should take medications to restore vascular patency. They will help normalize blood flow and pressure. Accordingly, the cloudiness will pass. If there is an infection that aggravates the patient's condition, antibiotics will be required.

Vasobral and Noben are great for vascular malfunction. They restore blood flow, normalizing the patient’s condition. Cloudiness in the eyes goes away along with other symptoms - weakness, difficulty in perception.

In all cases, it is recommended to instill Visin, Taufon, and take eye vitamins. Blueberry Forte has good properties.

Homeopathic treatment

Homeopathic treatment is also possible. Aconite, arnica, and camphor will be effective drugs. But they should be used only after examination by a specialist. The treatment itself should also be prescribed by a homeopathic doctor based on an accurate diagnosis.

So, arnica should be taken to normalize blood pressure and prevent fainting. The product Vertigohel copes well with nervous exhaustion and helps with excessive stress.

Osteochondrosis

Yes, diseases of the spine, in particular the cervical spine, can cause frequent darkening of the eyes. The fact is that inside the spinal column there is a special canal, inside which not only the spinal cord passes, but also important blood lines that feed the brain. If they are partially compressed, then blood in the required quantity will not be able to flow to the brain. Clamping can occur as a result of osteochondrosis. The result is impaired blood circulation in the brain.

Osteochondrosis of the cervical spine

On a note! The phenomenon of darkness before the eyes, resulting from osteochondrosis, is often observed in the morning or after sleeping on an uncomfortable pillow.

What to do if there is darkening in the eyes

The first step in case of frequent darkening of the eyes is to seek help from specialists to determine the cause of this manifestation. In rare cases of darkening, you need to analyze your own lifestyle recently. If you are overworked, dieting or living under stress, you may not need to seek medical help. You just need to eliminate all the factors that provoke darkening on your own.

Frequent manifestations of darkening in the eyes require qualified diagnosis. Depending on the identified cause, the treatment method will be determined. In turn, the patient will only need to strictly follow the doctor’s recommendations.

To prevent sudden darkening of your eyes, you should not get up suddenly or change your body position. You also need to increase your daily water intake and eat less salt. All this will help increase fluids circulating in the body. You should also rest more and be in the fresh air.

Arrhythmia

The pathology is often provoked by problems with water-salt metabolism or hormonal imbalance, but often also occurs as a result of heart failure and problems with the acid-base balance of the human body. Arrhythmia is divided into two types, one of which is shown in the table below:

• tachycardia;
• bradycardia.

There are two types of arrhythmia

In the first case, there is an increase in heart rate, in the second - a decrease. In both cases, a person may complain of darkening of the eyes, but this phenomenon is usually observed with bradycardia. With tachycardia, the patient experiences shortness of breath and a state of panic.

On a note! Darkening in the eyes is often noted by people who are dependent on weather conditions. When the weather changes, they may feel unwell.

Diagnostics

Since there are a huge number of diseases that cause darkening of the eyes, it will not be possible to immediately understand which specialist you need to contact. Therefore, the best place to start is to go to a therapist . It is he who, after a general examination and collection of anamnesis, will refer the patient either to specialized specialists or to certain types of studies.

Among highly specialized specialists, it is recommended to visit an ophthalmologist, who will rule out or confirm the presence of eye problems. You should also sign up for an MRI of the brain, ultrasound and vascular angiography. In some cases, it will be necessary to take a cardiogram or perform an orthostatic test.

Diagnostic features

Attention! The greatest value for the doctor at the first stage of the examination will be the result of the orthostatic test. It will allow you to identify the frequency of contractions of the heart muscle at rest and during active movements. It will also demonstrate the level of blood pressure when changing body position from horizontal to vertical.

An orthostatic test is carried out like this: doctors count the pulse several times, and also measure pressure, if possible, in different positions of the person’s body (standing, lying down). Moreover, measurements are taken immediately after changing the position, as well as after 60 seconds, 3, 5 and 10 minutes. These indicators are necessary to assess the rate of restoration of normal rhythm at rest. If the pulse increases by 19 beats, then the test is considered unsatisfactory; if by only 11, then the person’s tolerance to such changes is good.

Orthostatic hypotension

Orthostatic (postural) hypotension is an excessive decrease in blood pressure when moving from a horizontal to a vertical position. This diagnosis is established if systolic pressure decreases by more than 20 mmHg. Art. and/or diastolic pressure by more than 10 mmHg. Art.

This disorder is accompanied by the following symptoms: weakness, dizziness, loss of orientation in space, darkening of the eyes when standing up, sometimes ringing and congestion in the ears. All signs last from several seconds to several minutes, quickly disappearing if the person returns to a horizontal body position. Some patients with orthostatic hypotension may even lose their balance and fall when they abruptly get out of bed, and some may develop syncope and generalized seizures.

Important! Orthostatic hypotension is not a separate disease, but just a symptom that occurs when blood pressure regulation is disturbed against the background of various pathological conditions.

The most common causes of acute orthostatic hypotension are:

Why do monitors hurt my eyes?

• Decreased circulating blood volume (dehydration, blood loss).
• Taking medications (nitrates, calcium channel blockers, alpha blockers, antihypertensives, tranquilizers, antidepressants, barbiturates, antiparkinsonian drugs, loop diuretics, quinidine, vincristine).
• Taking large doses of alcohol.
• Prolonged bed rest.
• Adrenal insufficiency.

The most common causes of chronic orthostatic hypotension are:

• Age-related changes in blood pressure regulation in older people.
• Taking certain medications (described above).
• Disorders of the autonomic nervous system (vegetative-vascular dystonia).
• Eating foods rich in carbohydrates (postprandial orthostatic hypotension).

Despite the harmlessness of this condition, you need to remember that if your eyes regularly become dark and you suspect orthostatic hypotension, you should definitely consult a specialist, since very serious diseases can be hidden under the guise of such a disorder. For example: Parkinson's disease, previous cerebral stroke, transverse myelitis, spinal cord tumors, multiple sclerosis, aortic stenosis, cardiac arrhythmias, constrictive pericarditis, hyperaldosteronism, pheochromocytoma, etc.

Orthostatic hypotension does not always need to be treated. If the condition is not caused by some serious illness and does not bring significant trouble to the person, no drug therapy is required. The only thing is that you need to remember this feature of your body, and immediately after waking up, do not suddenly stand on your feet, but lie down for a while, then sit on the bed and only then get up.
