During pregnancy and breastfeeding, hormonal changes in the body can affect various aspects of health, including vision. While astigmatism itself may not be directly affected by pregnancy or breastfeeding, hormonal fluctuations can lead to changes in the corneal curvature and refractive properties of the eye. Some women may notice temporary changes in their vision during these periods, including fluctuations in refraction or the development of astigmatism. It is essential for pregnant and breastfeeding women to undergo regular eye examinations to monitor changes in their vision and ensure that any underlying eye conditions are promptly addressed.
