Vision during pregnancy and after birth: When to come for an exam and when to wait?
Pregnancy is a fascinating time. A whole symphony of changes happens in your body. Hormones work overtime, your body adapts to new life. And your vision? It often notices this transformation too.

Some expectant mothers suddenly experience blurred vision, drier eyes, or feel that glasses that worked perfectly fine until now don't quite do the job anymore. But it's not always necessary to rush out for new prescriptions. When does it make sense to book an exam, and when is it wiser to wait a little longer?
What actually happens to your vision during pregnancy?
Hormones, fluid retention, blood pressure changes, blood sugar fluctuations – everything pregnancy brings can affect your eyes as well. We most commonly see these changes:
- Blurred vision and prescription changes – due to fluid retention in the body, the cornea can thicken slightly and change its curvature, leading to unfocused vision.
- Dry eyes and increased sensitivity – hormonal changes affect tear film production and stability. Tear production decreases and their composition changes – mainly a reduction in the oil layer, which is crucial for tear film stability on the eye's surface.
- Lower intraocular pressure – in women with glaucoma, pregnancy can paradoxically improve pressure readings. This temporary decrease happens mainly in the second half of pregnancy.
These changes are usually temporary. After birth and once breastfeeding ends, vision typically returns to where it was before.
When does it make sense to get an exam during pregnancy?
There are situations when we definitely recommend an exam:
- Significant vision deterioration – if you're having trouble reading, driving, or recognizing faces. Any sudden vision change should be checked preventively.
- Flashes, sparks, light sensitivity, double vision, visual field loss, temporary vision loss, or severe headaches – these can be signs of preeclampsia, a serious condition associated with high blood pressure that typically appears after week 20 of pregnancy. In this case, contact your gynecologist immediately.
- You have diagnosed glaucoma or diabetes – in these cases, regular monitoring of the retina and intraocular pressure by an eye doctor is necessary.
And when is it better to wait?
If you feel your glasses fit slightly less comfortably but you can otherwise see without problems, don't rush into a new prescription. Your prescription can change during pregnancy, but it's usually just a temporary phenomenon.
Our tip: If possible, wait with measuring at least three to six months after birth, or until you finish breastfeeding. Vision typically stabilizes 2–3 months after completely stopping nursing, when hormone levels definitively return to their original state. Your body settles down and the measurement will be more accurate. You'll avoid having glasses made that might not serve their purpose a few weeks later.
Vision after birth – what to expect?
After birth, your body changes again. Many women feel their vision has returned to normal, but some start experiencing fatigue, blurred vision, or strain when looking at things up close or far away for longer periods.
This can be related to:
- hormone levels,
- sleep deficit,
- but also changed needs – you suddenly spend lots of time watching small details, whether during feeding or putting baby to sleep, or in nighttime lighting.
If you feel something's not quite right, reach out. After birth, we recommend having a complete eye exam ideally after 3–6 months, once your body has settled a bit.
If you feel something's off with your vision, feel free to come in. We might find that the change is minimal and we'll wait a bit longer with new glasses. But it's always better to come for a preventive check early, so we can start addressing any issues right away if needed.
