Why is it important not to change prescriptions for corrective lenses during pregnancy?

The importance of not changing prescriptions for corrective lenses during pregnancy is primarily due to the fact that changes in vision often stabilize after delivery. During pregnancy, hormonal fluctuations can lead to temporary changes in the shape of the cornea or fluid retention, which can affect how light is focused in the eyes. These changes can result in altered vision, such as blurred or fluctuating eyesight. However, many of these changes tend to resolve postpartum as hormone levels return to pre-pregnancy states and the body readjusts. Therefore, making new adjustments to eyewear before these changes stabilize could lead to unnecessary expenses and potentially ineffective corrections.

In contrast, other considerations, such as potential cost increases of eyewear or assumptions about improvements in eye function postpartum, do not address the immediate complexity of vision changes amid pregnancy. Additionally, the claim that vision issues are unrelated to pregnancy overlooks the fact that pregnancy can cause significant alterations in vision due to physiological changes. Focusing on the temporal stability of vision changes after delivery highlights the practical approach of delaying prescription alterations until after childbirth.
