You can chalk it up to the usual culprit: hormones. Hormones that support baby’s growth during pregnancy can cause fluid retention—and that can change your eyes in ways that could blur your vision. Possible eye changes include an altered shape or thickness of the cornea, the transparent part of the eye that covers the iris; lower-than-usual tear production, which can impact how well you see and increased pressure inside your eyes. The good news: This should all get better after baby is born. Keep in mind that blurry vision can be a sign of serious pregnancy complications like preeclampsia and gestational diabetes, so it’s a good idea to flag symptoms with your doctor during your next checkup.
