I’d never even knew what these were before today until a friend described them to me and told me to stare at something bright and white and see if I see them. Sure enough I did see some little dark floaty spots and cobwebby strings! Ever since I’ve been panicking! I read it can mean something serious and usually happens in older people! Im only 28! I was convinced I had retinal detachment and am going to lose my sight! I can only see them in bright white light, like a bright ceiling for example and I have to really concentrate and try to see them iyswim but sure enough I do see them. I don’t think they have started suddenly I think I’ve not noticed as I haven’t looked for them before. Has anyone else experienced these so young? Do they only get worse?
