Pregnancy can be a stressful time that has many different changes to the female body. One of these changes is in vision. Over the 9 months of pregnancy, your vision will undergo a few changes as time goes on. Not to worry, many of the vision changes are temporary and will disappear a few months after the delivery, but existing eye conditions may alter as well.
Changes in hormones, metabolism, fluid retention, and blood circulation can all affect your eyes and your eyesight during pregnancy. Water retention changes the thickness and curvature of the cornea. The change isn't huge, but it can be enough that the prescription for your glasses may need to be temporarily altered. Most women who have vision changes during pregnancy say that it is mainly a bit of nearsightedness, so nothing too major. However, due to these potential changes, it is not advised to get laser eye surgery during pregnancy or to be fitted for new contact lenses as these vision changes are only temporary and any drastic measures could lead to permanent vision problems following the pregnancy.
If you wear glasses, it is unlikely that you will need to change your prescription unless your eyesight undergoes major changes. If your vision alters more than you are comfortable with, make sure to get it checked to ensure that everything is in order and the pregnancy hasn't caused potentially serious damage. The chances are small, but it's better to be on the safe side.
As for pre-existing eye conditions, pregnancy can help or harm you. Glaucoma has the potential to be reduced during pregnancy, so your medication may need to be adjusted accordingly. Diabetes during pregnancy can cause damage to the retina, so it is advised to have constant vision screenings to ensure nothing is amiss. Your vision during pregnancy is important, both for you and for when the little one arrives. Make sure you focus on the both of you so that you both have a happily ever after.
