Should i worry?

Hey guys, i have pretty impeccable vision, never wore glasses or anything but the past year I noticed that when I go outside and look at the brightness outside I have floaters in my left eye. My house is dark with black out curtains and i just moved here about a year ago and compared to my moms house its much darker as far as the paint and everything so idk if my eyes adjust different or what. Also if im looking at a bright screen like the computer or a white wall i see a floater in my eye. Im 21 with a clean bill of health but my anxiety is making me worry. Is this normal?
