Is there anything wrong with me? Sudden blurred vision?
Blurred vision is VERY serious. however, it can be many different things. Call a doctor or go to one as soon as possible. I stared at optical illusions for 2 hours in elementary school and i got blurred vision and told my mom I couldn’t see right (i didnt tell her about the illusions) and she rushed me to the doctor and considered that i go to the hospital. It can be a sign of a blood clot in the brain, a stroke, or a tumor. But less seriously it can be a result of medication or who knows what.
