First of all, I'm new here and I don't know if this is where I should be posting this so sorry if it's in the wrong place. Okay to start I am a 14 year old boy and I am experienceing weird things in my vision, when I look into the sky I see little sparks of light moving all around as well as just random flashing sparks, they are not big but noticeable, I have floaters as well so I know that's not what it is and my eyes also feel strained, like how they feel when they are tired and you just want to close them, and this just all of the sudden started happening, I saw a thing on the internet where if you roll your eyes back and forth it will strengthen your vision so I started doing that for a while and then stopped and about the same time started experienceing the above, I'm really scared that I caused this and it's permanent, please help. This took a long time type on a tablet, anyway, again sorry if this was posted in the wrong area. Thank you!
