When a woman is pregnant, it’s not just her belly and feet that undergo changes. Shifting hormones and fluid retention may also affect the eyes, resulting in temporary vision impairment.
Water retention is thought to be the main cause of this slight change in eyesight; the body is holding so much water during pregnancy that it causes an increase in the thickness and curvature of the cornea and changes the shape of the eyeball. This results in blurred vision, double vision, and sensitivity to light. In some cases, women could see spots or flashes of light, or even temporary vision loss.

Those with existing eye conditions may also experience changes – for better or for worse. Women with diabetes may experience diabetic retinopathy which worsens eyesight, while those with glaucoma may see notice an improvement in their condition. It is not recommended though that pregnant women get new eyeglasses or contacts, since the change is only temporary and will go back to normal after a few months after delivery.
Vision is not the only thing affected by pregnancy and breastfeeding. Some women experience dry eyes (caused by lack of lubrication and moisture), causing their eyes to become red and have that itchy and burning sensation. Applying artificial tears usually helps relieve dry eyes as long as their physicians deemed it is safe for pregnant women to use.
However, changes in vision during pregnancy should not be ignored. Even if it’s just a slight change, it may be an indication of problems like high blood pressure or preeclampsia. A trip to the doctor when any changes in eyesight become evident is highly recommended.
