Postpartum vision

Je

So I'm 3 weeks postpartum and on medication because I developed postpartum preeclampsia 4 days postpartum. My BP is now normal and has not spiked or been over 140. Since I started the medicine I feel like my vision is different. I can see and it's not blurry but If I look up from screens and stuff I have to focus and squint a little bit. I know this isn't due to blood pressure since it's regulated but curious what else it could be from. Anyone else experience this? Also, to add I never had any symptoms of pre e except the high BP. No other signs.
