Along with the obvious transformation that pregnant women undergo, changes in hormones, metabolism, fluid retention, and blood circulation also can affect their eyesight and vision. To begin with, water retention can lead to increases in the thickness and curvature of the eye lens, which directly affects prescription lenses’ ability to correct for refraction errors. Most women undergoing such changes find they are a bit more nearsighted than they were before pregnancy. A change in prescription is not likely needed, but some do find it necessary. In any case, these changes are temporary and will reverse themselves within several months of delivery. In addition, pregnant women are likely to experience dry eyes, which can be helped with over-the-counter lubricating eye drops. Pregnancy produces physical and hormonal changes as well as blood volume changes, which can lead to temporary vision changes. Because glaucoma sometimes gets better during pregnancy, medications used to treat the eye disease may have to be adjusted.
