Blurred Vision in Pregnancy

Visual impairment during pregnancy is temporary. It occurs due to changes in the functioning of the woman’s body systems: hormonal, hemodynamic, immune, and metabolic. The result is an elongation of the eyeball. Vision is reduced and there are problems with recognizing objects at a distance, focusing, and eye fatigue.

Weakness of vision often occurs against the background of vitamin deficiency, lack of sleep, stress, or corneal deformities. An important role is played by hereditary predisposition and weakness of the optic nerve.

When Does Blurred Vision Start in Pregnancy?

The symptom is typical for the third trimester of pregnancy. A woman during this period gains a lot of weight, her stomach is large and this causes increased fatigue. Blood pressure increases in the third trimester. This often provokes pain in the head and eyes.


Complaints of blurred vision from expectant mothers come from the 34th week of pregnancy. Symptoms during the gestation period will be more exacerbated if the woman suffered from mild myopia, eye pressure, or migraines before conception.

It will appear already in the second trimester starting from the 14th week.

Blurred Vision pregnancy weeks

When will it end?

The cessation of blurred vision is timed to coincide with the completion of the gestation period. This is the 38th-40th week of pregnancy. Sometimes the symptom occurs solely as a result of severe fatigue and disappears after rest. Pregnancy-related visual impairment should resolve completely after childbirth. Normalization of vision occurs along with the restoration of hormonal balance.

How Does Blurred Vision Feel?

The symptom of blurred eyes is manifested in a decrease in visual acuity, the appearance of blind spots and zones, poor focus on details, and general eye fatigue. A pregnant woman observes a decrease in vision in the third trimester, especially in the evening. The picture is blurry, there is no clarity of detail, and it is difficult to recognize objects in the distance.


Blurred vision in an acute form is expressed in severe eye discomfort: dryness, pressure, and burning. The vision of a pregnant woman drops significantly. She cannot read text from a distance, has difficulty recognizing people at a distance, and complains of a decrease in the speed of her visual reaction.


A woman feels increased weakness of vision and eye fatigue a mild symptom. She does not see well at dusk, but the negative symptoms subside after a sound sleep. Visual impairment does not limit the life of a pregnant woman and is a short-term phenomenon.

Blurred vision as a symptom of pregnancy is not dangerous to health.

Prevention methods

The most effective way to prevent blurred vision is to identify eye problems early. Observe light hygiene in the room with a hereditary predisposition to myopia or hyperopia. Other preventive measures will not interfere: taking care of the health of blood vessels, solving pressure problems, and preventing back and neck pain. Let us consider in more detail the main ways to prevent a symptom:

Regular vision control

Visit an optometrist at least once a year. Get tested before conception. Check eye pressure and visual acuity. Eliminate problems found before pregnancy. This will significantly reduce the likelihood of severe visual impairment during the gestation period. It is better to wear glasses or decide on laser vision correction for myopia. Eye health is very fragile and needs constant monitoring.

Sun protection

Even if you do not have vision problems, it is better to wear sunglasses. They protect the shell of the eye from the harmful effects of ultraviolet radiation. This preserves the moisture and structure of the lens. Wear caps or wide-brimmed hats if you don’t like glasses. They will create a shadow over the eyes and prevent the direct influence of the sun’s rays.

Rest and gymnastics of the eyes

This preventive measure is mandatory for those who work at the computer. Monitor light and flickering frames have a bad effect on vision. Arrange a deloading break for the eyes during working hours. Close your eyelids, rub your eyeballs with light movements, and look into the distance, then at a nearby object. Perform circular eye movements and movements up and down.

Why Blurred Vision Occurs in Pregnancy?

The main causes of visual impairment during the gestation period are functional. There is a reorganization of the work of the body systems, and the shape and structure of the eyeball changes. It lengthens, which reduces the sharpness of focus, causing visual defects. Hemodynamics is transformed during pregnancy and this can provoke increased eye pressure. Visual impairment and blind spots appear.

The body of a pregnant woman is subject to great stress during restructuring, hormonal disruptions, and vitamin deficiencies. A lack of vitamins A, E, C, and B can cause visual impairment. A woman in position often suffers from poor sleep, which causes visual impairment.

A feeling of cloudiness can occur against the background of hormonal dry eyes. Estrogens affect the functioning of the meibomian glands. They produce the lipid component of the lacrimal membrane. The eye is less moisturized with a lack of estrogen.


Vision problems are best prevented. It is necessary to do everything so that the situation does not worsen if they have already arisen. Try to read less in a bad light, limit the time in front of the screen and the monitor, and take breaks from work. You can use harmless pharmaceutical products or medical techniques.

A course of vitamins

Doctors may prescribe vitamins or a mineral complex to improve vision. This should be done by an ophthalmologist. Such supportive therapy will reduce the severity of the symptom of blurred vision. The deficiency of vitamins supporting vision (C, E, A) will be eliminated. Give preference to natural vitamins. Take them exactly as directed by your doctor.

Corrective glasses

Your doctor may prescribe you to wear glasses if your vision has deteriorated severely. Most often this is not required. Myopia can develop during pregnancy if there was a predisposition to it before. Glasses should only be used when needed. There is no need to wear them all the time.


Sometimes an ophthalmologist may prescribe eye drops. These may be analogs of tears. The artificial tear works as a moisturizer which is completely harmless. It only refreshes the eyesight and keeps the mucous membrane of the eye moist. The use of washing drops reduces the risk of developing viral and infectious diseases, relaxes the eyes, and normalizes vision. Drops should not be vasoconstrictors.


Eye problems should not go beyond blurred vision. Urgently consult a doctor if you notice that the eyes show clouding of the lens, bursting blood vessels, or morning suppuration. A decrease in immunity in the third trimester of pregnancy can lead to infection with infectious or viral diseases of the eye. You should consult a doctor when visual impairment is accompanied by increased eye or blood pressure.

What Not to Do

You cannot rely on self-diagnosis with blurred vision. You cannot do without the help of a specialist if the symptom manifests itself in an acute form. Do not use questionable means and do not count on alternative medicine methods. Try not to overwork at work and get more rest. The main prohibitions for blurred vision:

Don’t drive

Behind the wheel is dangerous until vision is normalized. A slow visual reaction can lead to an accident, the consequences of which may be irreversible.

Don’t read for a long time

Excessive eye strain will exacerbate the symptoms. Evening reading in subdued light and the supine position is especially harmful. There is strong pressure on the eyeball.

Do not look at the phone screen without light

Phone backlight is bad for eyesight. A strong expansion of the pupil and an increase in the visual impulse occur in the dark.
