I'm not sure if it's because my last eye check was sometime back (in early 2019), but when I visited the optician in Dec 2020 (end of first trimester), my eyesight has deteriorated. Even with contact lens in my eyes I couldn't read out the small alphabets during the eye test.
I’m not sure if it’s a side effect but i had to wear glasses after i gave birth to my first😩 after 23 years of perfect eyesight. So it’s a yup for me, pregnancy made my eyesight bad haha
