Hormonal shifts during pregnancy can produce a wide range of unanticipated changes in your body, including changes to your eyes and vision. Most of these changes are transient and will return to normal once you give birth or complete breastfeeding.

It's critical to understand which vision changes are typical for an expectant mother and which may suggest an issue that requires visiting an ophthalmology practice.

Why Does Pregnancy Cause Eyesight Issues?
Almost every system of the body undergoes significant modifications as it prepares to carry a child. Changes in metabolism, hormone levels, fluid retention, and the cardiovascular system can all impact vision.

Other brief pregnancy problems, such as gestational diabetes, might cause vision changes. Possible causes to closely monitor during prenatal care include:

- Hormonal changes
It is widely recognized that hormonal changes during pregnancy can cause havoc on the body. Unfortunately, this can also affect your eyes. Water retention is frequently the culprit; as you see swelling in your ankles and joints, your eyes may be reacting unexpectedly.
Fluid retention in the eyes can increase pressure in the eyeball, resulting in a thicker cornea and blurred vision. You may also notice puffiness in your eyelids and decreased tear production, both of which can impair your vision.

- Gestational diabetes
Gestational diabetes is a type of transient diabetes that occurs during pregnancy. It affects around 10% of pregnant women in the United States and is caused by hormones released by the placenta during pregnancy. Similar to regular diabetes, there are numerous varieties based on the severity of the blood sugar imbalance, which can be treated with diet or insulin treatment.

Women who had diabetes before pregnancy and those who have gestational diabetes should regularly monitor their eyesight since blurred vision can signal high blood sugar levels. The risk of vision loss linked with diabetes increases during pregnancy, so blood sugar levels must be monitored at all times.

Women with gestational diabetes should have a diabetic eye exam, which includes dilating the eye and checking the retina for symptoms of retinopathy.

While modest changes in your eyes and eyesight are typical during pregnancy, if you experience chronic eye pain, vision loss, or discomfort, arrange an appointment with your doctor.

- Pre-eclampsia
Some substantial vision changes could indicate pre-eclampsia, a potentially hazardous condition that occurs in 5-8% of pregnancies. This condition is distinguished by high blood pressure and frequent protein levels in the urine.

Symptoms of the illness include momentary visual loss, light sensitivity, fuzzy vision, and the appearance of flashing lights. If you have these symptoms, seek medical attention right once.
When left untreated, it can lead to eclampsia and convulsions.

Common Pregnancy Vision Changes
1. Blurry vision
Hormonal changes during pregnancy may cause a shift in your vision. If you notice that your vision has become hazy or that your existing prescription eyeglasses (or contact lenses) are not working as well as they should, consult your eye doctor. Fluid retention can temporarily modify the curvature of your cornea, causing a change in your eyesight.

Your doctor may urge you to wait until after giving birth to evaluate your prescription because your hormonal levels will continue to fluctuate and frequently return to normal following breastfeeding. If your current prescription makes it difficult to drive or read, your optometrist may be able to recommend interim corrective glasses. Blurry vision during pregnancy is usually transient and can be caused by a variety of hormonal changes.

2. Dryness
Dry eyes are typical during pregnancy, particularly in the latter trimester. Dryness is typically caused by hormonal changes that will return to normal following childbirth. However, dryness can also indicate a more serious condition (such as gestational diabetes or pre-eclampsia), so consult a doctor if you are feeling dry eyes in addition to symptoms such as eye pain or vision changes.

Be sure to drink plenty of water, especially on hot days. Eating fruits and veggies might help you stay hydrated. To provide moisture, use lubricating eye drops that are available over the counter. Using a humidifier and wearing glasses (rather than contact lenses) can also assist.

3. Puffy eyelids
Puffiness around the eyes is a frequent symptom of pregnancy caused by water retention and other hormonal changes. Mild puffiness can be unpleasant or cause weariness, but consult your eye specialist if you have further symptoms, such as severe headaches, consult your eye specialist.
How to Find Relief: A cold compress applied to closed eyes can help minimize swelling. Water retention causes puffy eyes, so remain hydrated and avoid high-salt foods.

4. Flashing lights, spots, or unusual floaters
Contact your doctor if you notice flashing lights and/or spots in your eyesight, contact your doctor. When accompanied by additional symptoms such as high blood pressure and severe headaches, these visual anomalies may indicate pre-eclampsia.
