“Eyes dilated”

I'm 25 years,old i use solian 400 medication just few days ago my eyes started getting dilated it seem like i think too much but i'm actually not whenever im standing just above my eyebrows i keep raising my eyes and seem yo focus and unfocus on my sight abnormally but it goes away when i sit down or lay down and look at the wall or ceiling and think of things to calm down my mind and sight movement i just wanna know is it a solain 400 symptom or side effect i read about it online google said it is i recently quit it then used it again without doctor consolation because i had some vad thoughts which i knew i needed the medicine again but now this is happening to my eyes and also when i play or do something and get drifted into some conversation or activity my sight gets normal and my behavior in my eyes
