Eyes may change somewhat during pregnancy due to fluid retention, increased blood volume, fluctuation of hormones and other physical changes that are part of pregnancy.  Usually these changes are temporary and resolve after the baby is born, or after weaning a breast-fed child.  Vision changes tend to be minor and don't require a new eyeglass prescription.  LASIK or other refractive surgeries should not be performed when a woman is pregnant or breast-feeding.

A condition known as dry eye syndrome may result from hormonal fluctuations.  Talk to your eye physician about lubricating drops and other treatment options that are safe during pregnancy.  Wearing contact lenses may be uncomfortable when dry eye is present.  Eating foods high in omega-3 fatty acids, such as salmon, walnuts, and flax seeds, may help improve dry eye syndrome and also supports good overall health.

If your vision becomes very blurry, it may signal serious conditions such as high blood pressure or gestational diabetes.  If this occurs, you should contact your obstetrician immediately.
