I got this issue too. For my case sometimes it’s blurry sometimes it’s double vision. One day I look at my face in the mirror and saw 4 eyes and 2 lips. At first putting on eye drops and closing my eyes for 20 mins could fix it. But getting to my 3rd trimester, sometimes 2 hrs sleep couldn’t get the vision back, unless I rest for whole day. Checked with some mums, some are having this issue and it goes back to normal after delivery. However, this could be sign of pre-eclampsia if you have high BP. So better checked with your gynae. For my case, my gynae is still monitoring as my BP is still on acceptable range.
I googled about this before and believe it or not, it is very normal for blurry visiom during pregnancy although it is not common. You can still ask your gynae though.
U can ask ur gynae ok
