Vision fell: why it happened and what to do

Human sight is a unique natural gift that allows us to see objects at different distances and in motion, to perceive colors and shapes. If the image is not as clear as before, take action. The reasons for the deterioration of eyesight are different, but most often this problem is faced by office workers, intellectuals (working with texts, tables), "active" viewers. Next, we will consider the main causes of deterioration in visual acuity and tell you what can be done to solve the problem.

Definition of a symptom

When the vision deteriorates, people see the blurred, not clear, can not read the text at a long distance.The most common reason for the appearance of such problems is eye fatigue, associated with prolonged visual loads.For good vision at close distances, the ciliary muscle (it is located inside the eye) responds, changing the shape of the lens and refracting its force.

Structure of the eye

The most common cause of vision deterioration is the constant eye fatigue.

If you constantly work at a computer, read a lot (especially text in small print), the ciliary muscle experiences overload, and the visual acuity noticeably decreases.To remove the spasm of accommodation, eye drops are used. Only consider - they should not be assigned independently, because harm can exceed the benefit if uncontrolled use is made.Also, the reduction in visual acuity can cause various diseases, so first carry out a diagnosis.

Causes

The main causes of impaired vision:

1. Bad muscular work- the ciliary muscles that control the lens become weak and flabby as a result of a constant concentration of sight at a single point. Therefore, train them (you need to look alternately at those who are close, then at distant objects).
2. Retinal aging- with age, the photosensitive pigment, responsible for the clarity of the image, is destroyed, and visual acuity is reduced. Several slow down such changes can be due to a special diet rich in vitamin A. Remember that vitamin A is fat-soluble, so the same carrots should be filled with butter or sour cream.
3. Deterioration of blood circulation- The retina of the eye is an organ very delicate, it suffers from any changes in the body. Poor blood circulation is one of the main causes of sharp reduction in visual acuity. Regularly visit an ophthalmologist to timely diagnose the problems and take action.
4. Overexertion of the eyes- and as a result of too bright light, and because of excessive voltage with insufficient lighting. Therefore, never read in transport, and in bright sun wear protective goggles with UV filters.
5. Dryness of mucous membranes- only a sufficiently moistened shell is clean, transparent and normally transmits reflected light from the objects. Therefore, if the eye is "dry we see worse.

Although the main enemy of good vision is the screen (TV or computer), one can not exclude the effect of such factors as poor blood circulation, dry eyes, aging of the retina.

Possible diseases

We found out that the eyes can get tired, the visual acuity reduces the dry mucosa, in addition, the irreversible changes in the retina occur with age.But they can negatively affect the quality of the display of objects and some eye diseases. Average of them:

• glaucoma;
• cataract;
• dry eye syndrome;
• hyperopia, developing with age;
• diabetic retinopathy.

To increase visual acuity in this case, therapy of pathology, which became the main reason for its reduction, is carried out.

Diagnostic Methods

To improve vision, you need to determine the cause of its decline. Therefore, the diagnosis includes a whole range of measures.

The causes of ophthalmic problems are many - in order to prescribe effective treatment, the doctor must determine the cause of the decrease in visual acuity accurately.To do this, he:

• checks the sharpness of the images;
• measures the intraocular pressure;
• checks refraction (refraction - the ability to refract the rays of light);
• directs the patient to ultrasound examination of the internal structures of the eye;
• explores the field of view;
• examines the refractive power and shape of the cornea;
• diagnoses possible internal deviations and pathology.

Treatment

The treatment regimen is appointed only after diagnosis - it depends on the causes of vision loss.It can include special gymnastics, intake of vitamin preparations, laser correction.Typically, the doctor recommends a change in lifestyle- Do not read lying in the bus, every hour while working at the computer to take breaks and so on.

Prevention

Any disease is easier to prevent than treat. To always see things clearly:

• Do not sit too close to the monitor.
• Try to watch less TV.
• Do all the work with comfortable lighting for the eyes.
• Regularly do special gymnastics.
• Let's rest our eyes.
• Take vitamins, balance the diet.
• Get enough sleep.

Preventive measures aimed at maintaining eye health are simple - it is enough to alternate loads with rest, get enough sleep, do gymnastics and eat right.

conclusions

Visual acuity decreases with age, as a result of overwork, dry eyes, circulatory disorders in the retina and a number of ophthalmic diseases (cataracts, glaucoma). The scheme of treatment is prescribed only by a doctor after a thorough diagnosis. We recommend not to ignore preventive measures (charging, healthy sleep, etc.) - they will help restore visual acuity and avoid a number of problems in the future.
