eyesight affected?

[Acacia]

Something else to consider is that during pregnancy (especially during later pregnancy) the fluid levels in your body continue to increase because of increased hormone production - this includes the tissues around your eyes. This can affect the sensitivity of your cornea and thus affect the refraction of your eyes, changing where light focusses on your retina, which directly affects your ability to see clearly. The sensitivity of your cornea is why it is advised that you don't wear contacts during pregnancy - your contacts can cause irritation and your eye often rejecting the contact lens. This is one of the most common causes for issues with eyesight during pregnancy.

Hormone production can also change the pressure within the eye itself (lowering it), changing the shape of your eyeball which would also change the focal length of your eyesight (meaning that light again focusses differently to normal on your retina).
