About 20 minutes ago, a blurred line apeared in my vision on my left eye. I'm freaking out because i have no idea what it is. I'm only 18. I've been wearing glasses since i was 13. My mom is at work and im currently baby sitting my little sister (toddler) so i cant sit down and rest. My left eye also feels a little weird. I'm not experiencing any other problems except that blurred line. Please help me figure out what it is so i can calm down and focus more on my little sister.
