Yan talaga, normal lang yan! A few of us pregnant moms experienced the same thing, parang blurry or mahirap mag-focus ang mata, lalo na towards the end ng pregnancy. It's because of the hormonal changes and the extra fluids na nag-accumulate sa body, kahit sa mata, kaya parang nabago ang shape ng cornea mo temporarily. Pero don't worry, usually bumabalik to normal after birth, though some moms say it takes a few weeks or months pa.
