Frequently Asked Questions

Is blurry vision normal during pregnancy?

Mild blurriness from corneal changes is common and not dangerous. However, sudden or severe blurry vision — especially in late pregnancy — is a warning sign of preeclampsia and requires immediate evaluation.

Can pregnancy permanently change my vision?

Most vision changes are temporary and resolve within weeks to months after delivery. Avoid updating your prescription during pregnancy for this reason.

What do flashing lights or spots in vision mean during pregnancy?

Seeing flashes, spots, or floaters — especially with headache or swelling — is a warning sign of preeclampsia or severe hypertension. Call your provider or go to the ER immediately.

Can I wear contact lenses during pregnancy?

Many women find contacts less comfortable during pregnancy due to dry eyes and corneal changes. Daily disposables are often more comfortable. Avoid wearing them during episodes of blurriness or discomfort.
