Yes, pregnancy can cause blurry vision due to hormonal changes, fluid retention, and increased blood flow, which affect the eyes.
Can Pregnancy Cause Blurry Vision? | Eye-Opening Facts for Moms
Pregnancy is a beautiful journey, but it also comes with a variety of unexpected symptoms—blurry vision being one of them. As a mother who has experienced this firsthand, I know how unsettling it can be. During my pregnancy, there were days when my vision felt a little off, and it’s something that many expecting moms go through. Let’s dive into why this happens and what it means for your health. Hormonal shifts and fluid retention don’t just change your body—they can affect your eyesight too.
Pregnancy can certainly impact your vision. While some vision changes are temporary and harmless, others may signal more serious issues. This article will explore why blurry vision occurs during pregnancy, the factors contributing to it, when to be concerned, and how to manage it.
Why Does Pregnancy Cause Blurry Vision? | The Science Explained
Blurry vision during pregnancy occurs due to a combination of hormonal changes, fluid retention, and increased blood flow, all of which can affect the eyes. Below are the key reasons why your vision might be affected:
- Hormonal Fluctuations: Pregnancy hormones, particularly progesterone and estrogen, cause changes in the cornea, making it more curved and thicker. This can blur vision.
- Fluid Retention: Water retention during pregnancy affects not only the feet and hands but also the eyes, altering the thickness and shape of the cornea.
- Increased Blood Volume: Blood volume increases significantly to support the baby’s growth, causing small changes in the blood vessels around the eyes, which can affect vision.
- Dry Eyes: Hormonal changes can reduce tear production, leading to dryness and discomfort, which further contributes to blurry vision.
Table 1: Causes of Blurry Vision During Pregnancy
| Cause | Description | Symptoms | How to Manage It |
| Hormonal Changes | Changes in the cornea thickness due to progesterone and estrogen | Blurry vision, discomfort | Monitor symptoms, consult doctor |
| Fluid Retention | Water retention alters cornea shape | Swollen eyes, blurred vision | Stay hydrated, reduce salt intake |
| Increased Blood Flow | Increased blood flow causes pressure on small eye blood vessels | Mild to moderate vision changes | Regular eye exams, rest eyes |
| Dry Eyes | Decreased tear production due to hormonal changes | Itchy, irritated eyes, blurry vision | Use lubricating eye drops |
Common Eye Conditions Related to Pregnancy
Blurry vision is sometimes a sign of an underlying condition. Below are the most common eye-related conditions associated with pregnancy:
1. Gestational Diabetes
Gestational diabetes can develop during pregnancy, leading to fluctuating blood sugar levels, which may temporarily affect your vision. High blood sugar can cause swelling in the lens of the eye, leading to blurred vision.
2. Preeclampsia
Preeclampsia is a serious pregnancy complication that affects blood pressure and can cause vision disturbances such as blurriness, seeing spots, or flashing lights. This condition requires immediate medical attention as it can endanger both the mother and baby.
3. Central Serous Chorioretinopathy (CSCR)
In rare cases, pregnancy can cause central serous chorioretinopathy, where fluid builds up under the retina. This condition may lead to temporary vision loss or blurriness and should be treated by a specialist.
4. Dry Eye Syndrome
The hormonal shifts during pregnancy can cause dry eyes, leading to discomfort and blurry vision. This condition is usually temporary and can be managed with artificial tears or lubricating eye drops.
Table 2: Eye Conditions That Can Cause Blurry Vision in Pregnancy
| Condition | Description | Symptoms | Risk Level |
| Gestational Diabetes | High blood sugar affects the eyes | Blurry vision, difficulty focusing | Moderate |
| Preeclampsia | High blood pressure causing vision disturbances | Blurriness, flashes, spots | High (requires medical attention) |
| Central Serous Chorioretinopathy | Fluid buildup under the retina | Vision loss, blurriness | Rare, but serious |
| Dry Eye Syndrome | Reduced tear production due to hormonal changes | Dryness, irritation, blurriness | Low (manageable) |
Can Blurry Vision During Pregnancy Affect Your Daily Life?
Yes, blurry vision during pregnancy can affect day-to-day tasks like driving, reading, or working on a computer. While the changes are usually mild and temporary, it’s important to take precautions, especially when performing activities that require sharp focus.
Managing Blurry Vision:
- Regular Eye Exams: Ensure you have routine checkups to monitor any changes in vision, especially if you already wear glasses or contacts.
- Rest Your Eyes: Take breaks from screen time and avoid eye strain.
- Stay Hydrated: Drinking enough water can reduce fluid retention and dryness, helping to minimize vision problems.
- Use Eye Drops: Lubricating drops can help relieve dry eyes.
- Avoid Driving If Vision Is Impaired: If you experience significant blurriness, avoid driving until your vision improves or consult a doctor.
Table 3: Tips for Managing Blurry Vision During Pregnancy
| Action | Why It Helps | How to Implement It |
| Eye Exams | Detects early signs of eye conditions | Schedule regular appointments |
| Hydration | Reduces fluid retention and dry eyes | Drink 8-10 glasses of water daily |
| Eye Rest | Prevents eye strain | Follow 20-20-20 rule (20 seconds break every 20 minutes) |
| Use Eye Drops | Relieves dryness and irritation | Use pregnancy-safe drops |
| Avoid Strain | Prevents further discomfort | Limit screen time and reading |
When to See a Doctor for Blurry Vision During Pregnancy
Most cases of blurry vision are harmless and will resolve after childbirth. However, in some instances, vision changes could indicate a more serious problem. Seek medical attention if:
- You experience severe or sudden vision changes like double vision, flashes of light, or blind spots.
- You have consistent headaches along with blurry vision.
- You notice swelling in your face or hands along with vision issues, as this could indicate preeclampsia.
- You have high blood pressure or gestational diabetes, as these conditions can exacerbate eye problems.
FAQs – Can Pregnancy Cause Blurry Vision?
Is blurry vision during pregnancy common?

No, in most cases, vision changes during pregnancy are temporary and resolve after delivery. However, conditions like gestational diabetes or preeclampsia may cause more serious, lasting damage if not treated promptly.
What causes blurry vision during pregnancy?
Blurry vision is primarily caused by hormonal shifts that alter the shape of the cornea, fluid retention that affects eye pressure, and dryness due to decreased tear production. These changes typically return to normal after pregnancy.
Is blurry vision a sign of preeclampsia?
Yes, blurry vision can be a symptom of preeclampsia, a serious pregnancy complication related to high blood pressure. Other symptoms include seeing spots or flashes of light, swelling, and severe headaches. If you suspect preeclampsia, seek immediate medical attention.
