Pregnancy and Your Eyes: Vision Changes to Expect

Why Pregnancy Affects Your Eyes

Hormonal shifts, fluid retention, and changes in blood circulation during pregnancy can all have subtle effects on the eyes. These changes are usually temporary and resolve after delivery, but they're common enough that many expecting mothers notice some degree of visual change at some point during pregnancy.

These effects aren't unique to the eyes — the same hormonal and fluid shifts that can cause swelling in the hands and feet during pregnancy are often behind the subtle changes noticed in vision too. Thinking of eye changes as part of this broader, whole-body pattern can make them feel less unusual or worrying.

Common Temporary Changes

• Dry eyes: Hormonal changes can reduce tear production or alter tear composition, leading to dryness, irritation, or a gritty feeling.
• Mild blurring: Fluid retention can slightly change the shape and thickness of the cornea, which may cause minor, temporary blurring of vision.
• Contact lens discomfort: Changes in corneal shape and tear quality can make contact lenses that previously fit well feel less comfortable during pregnancy.

These changes typically resolve within a few months after delivery as hormone levels and fluid balance return to their pre-pregnancy state.

Because your prescription for glasses or contact lenses can shift temporarily during these months, it's generally best to avoid getting a brand new, permanent glasses prescription or considering any refractive surgery until some time after delivery, once your vision has had a chance to settle back to its usual baseline.

Pregnancy and Diabetic Retinopathy

Women who have diabetes, including gestational diabetes, need particular attention to their eyes during pregnancy, since pregnancy can accelerate existing diabetic retinopathy or allow it to progress more quickly than usual. An eye examination is generally recommended early in pregnancy for women with pre-existing diabetes, with follow-up as advised by the eye doctor based on findings.

Pregnancy-Induced Hypertension and Vision

Conditions like preeclampsia, which involve a rise in blood pressure during pregnancy, can affect the blood vessels in the retina and, in some cases, cause visual symptoms such as blurred vision, light sensitivity, or seeing spots or flashing lights. These visual symptoms, especially when combined with other signs like severe headache or swelling, should be reported to your obstetric care team promptly, as they can be an important sign of a condition that needs timely management.

Because these visual symptoms can be an early warning sign rather than just an inconvenience, they're taken seriously by both eye doctors and obstetric teams. Never hesitate to mention new visual symptoms during a high blood pressure pregnancy, even if they seem to come and go.

When to See an Eye Doctor During Pregnancy

• Vision changes are significant rather than mild
• You have pre-existing diabetes or develop gestational diabetes
• You notice flashing lights, spots, or a curtain-like effect in your vision
• Blurred vision is accompanied by headache, swelling, or high blood pressure readings
• Dry eye or contact lens discomfort is significantly affecting daily comfort

Most pregnancy-related eye changes are mild and temporary, but because a few can signal something that needs prompt attention, it's always reasonable to mention any new visual symptom to your doctor rather than assuming it will simply pass.

It's also worth mentioning any eye symptoms at your regular obstetric check-ups, even if they seem minor, since your obstetrician and eye doctor may want to coordinate care, especially if you have diabetes, high blood pressure, or any other condition that can interact with pregnancy and affect the eyes.
