Are you having trouble noticing small details, or are your eyes becoming more sensitive to light?
Blurred vision is an annoying symptom that affects some pregnant women and can be distressing, especially if it happens during the first weeks of the 3rd trimester. The blurred vision may be only temporary and normal in some cases; however, it may indicate an underlying serious health issue such as preeclampsia.
In this article, we will clarify the reasons for blurred vision during pregnancy, the link between hormones and vision, when you should visit a doctor, and the ways through which you can effectively manage this symptom.
What Is Blurred Vision and How Does It Occur During Pregnancy?
Blurred vision refers to the lack of clear vision, and it may be associated with symptoms such as eye irritation, spots or flashes of lights, or temporary vision loss.
In pregnant women, blurry vision can occur suddenly or progressively as a result of various changes occurring in the eye and nervous systems.
In many cases, it is transient and not harmful. However, it could indicate serious complications in other medical disorders, particularly hypertension or circulatory problems in the eyes.
How Do Hormones Affect Eyes and Vision?
At around the 31st week of pregnancy, there are increased levels of estrogen and progesterone. This leads to alterations in eye tissues as a result of:
- Fluid retention: The hormones released during pregnancy relax the blood vessels, resulting in fluid retention, corneal swelling, and changes in the corneal curvature, ultimately impacting vision.
- Dry eyes: The hormonal changes affect the tear glands function, reducing tear secretion and resulting in dry and irritated eyes.
- Sensitive eyes: the eyes can become overly sensitive to light and even irritated by screen time or dry air in the environment, making the vision seem blurry.
Relationship of High Blood Pressure with Vision
Pregnancies with high blood pressure or preeclampsia are a significant risk factor for blurred vision, because it causes contraction of the blood vessels that supply the eyes.
This process may be accompanied by other symptoms, such as headache, upper abdominal discomfort, swelling in the hands and face, and weight gain due to the accumulation of fluids.
If you have any of these symptoms or blurred vision, you should see a doctor for evaluation and to perform the necessary tests, such as blood pressure measurement and urine analysis.
Effects of Low Blood Sugar on Visual Clarity
When the levels of blood sugar decrease, transient vision disturbances may arise, especially for women with gestational diabetes or with rapid changes in dietary habits.
This is because the eye cells, particularly the retina that is responsible for sharp vision, require glucose for energy.
When Is Blurred Vision an Emergency?
Blurred vision during pregnancy is a condition that one should not ignore, especially if accompanied by the following symptoms:
- Serious and chronic headache.
- Dizziness or fainting.
- Abdominal or upper stomach pain.
- Sudden swelling of the face or hands.
- Noticeable weight gain.
- Vaginal bleeding or fluid leakage.
- Pain in the eyes.
These symptoms can indicate preeclampsia or other health conditions, for which immediate care is needed. In all instances, one should immediately consult a doctor for blurred vision.
Diagnosis of Blurred Vision During Pregnancy
Early diagnosis can prevent complications, ensuring the safety of both mother and baby. Diagnosis is predominantly based on careful review of symptoms of the pregnant woman, a clinical examination including measurement of blood pressure, and an initial eye examination.
The doctor may order the following tests:
- Urine test: To check for protein, which may be indicative of preeclampsia.
- Blood tests: These are done to evaluate liver and kidney functions.
- Eye exam: To evaluate the retina and the blood vessels that supply the eye.
- Neurological testing or brain imaging: Recommended if neurological complications are suspected.
Treating Blurred Vision During Pregnancy
Blurred vision treatment depends on its cause:
Treating Hormonal Blurred Vision
This usually subsides after giving birth. For the management of blurred vision, either from hormonal changes, light sensitivity, or dryness of the eyes, you can:
- Rest your eyes.
- Keeping the eyes hydrated.
- Limiting the amount of time in front of screens and taking breaks during reading to reduce visual strain.
- Using moisturizing eye drops after consulting your physician.
- Avoid dry environments or conditioned air.
Blurred Vision Associated with High Blood Pressure
Management requires close monitoring and may include medications for the treatment of high blood pressure. In some situations, the physician may need to induce labor.
Managing Blurry Vision caused by Low Blood Sugar
Always follow your doctor’s advice and do not take any drugs without consulting your doctor. Treatment includes:
- Eating a balanced diet with small and frequent meals to keep insulin levels steady.
- Avoiding skipping meals.
- Engaging in strenuous physical activity without adequate nutritional support.
- Avoiding the overuse of insulin or hypoglycemic medications (for gestational diabetes).
- Avoid sudden changes in diet or very low-carb diets altogether.
Tips to Avoid Blurred Vision during Pregnancy
Prevention is better than a cure. A few tips are as follows:
- Regular blood pressure tests, especially in the third trimester.
- Take adequate rest and sleep.
- Avoid excessive screen time and visual strain.
- Hydrating your body and keeping your eyes moist.
- Eating a healthy, balanced diet containing lots of vitamins, minerals, and omega-3.
- Consult with your doctor if symptoms are not usual.
Does Vision Return to Normal After Childbirth?
Vision problems occurring during pregnancy will resolve themselves after the delivery as soon as the hormonal levels stabilize and blood pressure normalizes.
On the other hand, mothers with severe preeclampsia may need to be followed by an ophthalmologist to avoid any possible damage to the eyes.
Finally…
Blurred vision around the 31st week of pregnancy may be considered normal when brought on by hormonal and physical changes, but it could also mean serious health conditions such as preeclampsia. Knowing the causes, monitoring the accompanying symptoms, and acting on time help protect your health and your baby’s. Never hesitate to seek medical help when you need it.
