My eyes are so much drier and water all the time now so I've got eyedrops I use a few times a day. My prescription has also changed from a positive to a minus so I had to get new glasses. Optician said all of that was normal and common which I find crazy. Might be worth an eye test x
It’s so hard to say because it could be completely normal but then sometimes blurred vision can be a cause for concern - defo speak to your midwife just to be safe z
