How Pregnancy Can Affect Your Eyesight

Pregnancy can impact almost every part of a woman’s body and health — including her eyes. In fact, an estimated 14% of pregnant women report experiencing visual changes during pregnancy that usually resolve on their own within a couple of months after giving birth.

Knowing the different visual symptoms that can present when you’re expecting can help alert you to potential underlying health concerns that your physician may need to address.

Normal Visual Changes During Pregnancy

Blurred Vision

Blurred vision is the most common visual symptom that pregnant women may experience. Hormonal fluctuations are usually to blame for the temporary decrease in visual acuity, and your eyesight will likely return to normal soon after giving birth.

The influx of pregnancy hormones causes fluid retention in some areas of the body and can cause the cornea to thicken slightly. As a result, the light entering the eye isn’t focused accurately and vision may be blurred.

Less commonly, blurred vision can signal gestational diabetes, a pregnancy complication affecting 6-9% of pregnant women. The rise in blood sugar level impacts the focusing lens of the eye, leading to blurry vision. If you are diagnosed with diabetes, including gestational diabetes, it’s a good idea to book an eye exam to monitor for retinal changes.

Blurred vision is also a common side effect of dry eye syndrome, a condition characterized by tears that don’t adequately lubricate the eyes, which can be brought on or exacerbated by pregnancy.

Eye Dryness

Pregnancy hormones can cause a reduction in the amount of tears your eyes produce or affect the quality of the tears. These changes can affect a woman throughout her entire pregnancy, but studies show that eye dryness is particularly common in the last trimester. For this reason, some women find it difficult to wear contact lenses in their third trimester and temporarily switch to glasses.

Eye Puffiness

Yet another body part that swells during pregnancy: the eyelids and tissues around the eyes.

Pregnancy-related water retention may cause your eyelids to appear puffier than during your pre-pregnancy days. You may also notice darker areas under the eyes. If your puffy eyes bother you, try limiting your salt and caffeine intake, as they can worsen the problem.

Visual Changes That May Indicate a Problem

The following visual changes warrant a prompt call to your eye doctor or obstetrician to rule out any underlying complications.

Flashes or floaters

Seeing stars during pregnancy can signal high blood pressure, which is associated with preeclampsia — a serious medical condition that requires close monitoring by your physician and possible treatment.

It’s crucial to have your blood pressure monitored throughout your pregnancy, as preeclampsia can potentially endanger the life of mother and child, as well as damage the cornea and retina.

Temporary vision loss

Temporary vision loss is concerning for pregnant and non-pregnant individuals. Vision loss is another warning sign of preeclampsia, so contact your doctor promptly if you suddenly lose any portion of your visual field.

Sensitivity to light

Light-sensitivity can either be a normal side effect of fluid retention in the eye, or it can signal dangerously high blood pressure and preeclampsia.

Why are regular eye exams important?

Having your eyes evaluated by an optometrist on a regular basis is crucial for detecting early signs of eye diseases and changes in your prescription, including during pregnancy. Many serious eye diseases don’t cause any noticeable symptoms until they’ve progressed to late stages, when damage to vision may be irreversible. Whether or not you wear glasses or contact lenses for vision correction, ask your optometrist about how often to schedule a routine eye exam.

Will my baby need an eye exam after birth?

According to the American Optometric Association and the Canadian Association of Optometrists, babies should have an eye exam within the first 6-12 months of life, even in the absence of noticeable vision problems. Healthy vision is a significant part of healthy overall development, so be sure not to skip your baby’s eye exams!

Why Are Dilated Eye Exams So Important?

Having your eyes dilated during an eye exam may seem like a nuisance. But when you consider the benefits of a dilated eye exam, the temporary blurred vision and sensitivity to light that typically follow are definitely worth it.

What Are Dilated Eye Exams?

At some point during a comprehensive eye exam, your optometrist will shine a bright light into your eyes to examine the back of your eye, called the retina. The problem is that bright light causes the size of the pupil’s opening to shrink, which makes it hard for the optometrist to see a large portion of the retina.

That’s why eye doctors apply special eye drops in each eye to keep the pupils open. A dilated pupil allows for a much more accurate assessment of your eye’s structures, including the focusing lens, blood vessels and tissues at the back of the eye called the retina, as well as the optic nerve and macula.

Dilating the eyes makes it easier for your optometrist to detect the following conditions and diseases:

Cataracts
Glaucoma
Diabetic retinopathy
Macular degeneration
Retinal tumor
Retinal detachment or retinal tears
Eye floaters

It’s important to note that many of these conditions can develop without noticeable symptoms, until they cause vision loss at which point treatment may be more challenging, making dilated eye exams all the more crucial.

The Dilation Process

First, your eye doctor will apply eye drops to each eye to trigger dilation of the pupil. Your eyes should be fully dilated about 10-20 minutes later.

Your eyes will remain dilated for 4-6 hours, and during this time you may be sensitive to light. That’s because the larger pupil allows more light than usual to enter the eye. Many patients find it more comfortable to wear sunglasses until their eyes return to normal.

Reading and using a computer may be difficult with dilated eyes, and your vision may be blurred. Some patients report feeling a tightening sensation in their eyelids, or headaches.

At what age should one have a dilated eye exam?

You should have your dilated eye exam no matter your age. Most eye doctors will dilate a new patient at their first exam regardless of age to get a baseline of their retinal health.

Will I be able to return to work after a dilated eye exam?

Everyone reacts differently, so it’s hard to tell. If your job requires you to focus on small print or detail, it may be challenging. Typing and writing may also be difficult with dilated pupils. To be on the safe side, book your appointment at the end of your work day, clear your schedule after your eye exam and only plan to do activities which aren’t visually demanding.
