I am a 14 year old male who has been experiencing some strangeness in my eyes. I might be overreacting or over thinking things, I also get worried easily, so yeah. First of all, I would like to start with me all of a sudden losing vision in my eye, this doesn't happen in both eyes this usually happens in only one eye and it occurs for a split second. It's usually like a quick curtain over my vision, it doesn't really take all of my vision, maybe it does, because it's pretty quick. Sometimes it just fades in for one second, and not as fast, like just a loss of vision fades in for a bit then it fades out. Second of all, this might be normal but after looking at bright light then looking away I usually see a halo or just a filled circle that is bright, and a bit colorful, even when closing my eyes after looking at bright light that happens. Not sure, that might be a normal thing a human experiences. Now with hazy/blurry vision, when I get up from my bed or my chair after sitting there for a long time my vision gets all blurry for a couple of seconds then fades back to normal, what does this mean?! And yes, at this age I will ask my parents, but first I want to make sure if I'm experiencing something that needs medical help. Thank you!
