I have been suffering for 3 months now. I have about 6 medium size ones present in my vision and I am only 20. They are all of the thread type, but some look like smoke because some are clumped into a spider like form. They are very visible and are present in any room with medium lighting or greater. All I have been doing is trying to find the cause of my eye floaters for the last three months and obsessing over it. I have been to 6 eye care professionals which say my eyes are healthy. I am also currently studying human kinetics. In my program we take a lot of time studying the development of the visual system and from my experience with eye floaters, I believe the problems is with the development of the visual system. It's not that anything is wrong with it, it is just that it has been modified and trained to make eye floaters visible. My eye floaters became gradually more visible over weeks. The reason why they have become gradually more visible is because I have been focusing on them so much that now even the slightist shawdow my floater produces will be recognized by the brain. This theory only applies to people whose floaters did not just appear suddenly. This applies for people who have noticed floaters getting worse gradually since the onset. Everyone has eye floaters and i know this for a fact. You just need to train yourself to see it. The first time I ever saw my eye floaters was when I was outside waiting for a bus. It was extremely bright and i saw my first floater. This was the darkest floater I had and that is why i saw it. I thought nothing of it and continued on for 2 weeks without even noticing it again. And trust me, it was just as dark back then as it was now. Once my exams were almost over and I had more time on my hands I started to pay attention to it and found out i have about 5 more of them. After 3 solid days of looking at them all day, they became visible all the time. I remember looking against a wall in my hallway and trying desperately to see them and I could not, 2 days later they were as dark as can be against that wall. Once they became this visible I have been constantly asking people if they see what I see. My brother had no idea what i was talking about until i mentioned it. It took him a week before he could see his and now he see's his all the time(althought not as bad as I do, he only has 2-3 of them). Same thing happened with my other brother and mother. I have basically trained them all to see it. They can all see it indoors when they never even knew what a floater was before I brought it up. My brothers have also know an increase in floaters and have also noticed them becoming more visible. Many of my friends see a couple eye floaters as well. Some people have barely any, some people have some, and some people have a lot. Another interesting thing is most of my grandparents and uncles too have gone through dealing with floaters. All said it was hard for the first 2 weeks because all they would see is their eye floaters, but gradually they became less and less noticeable after ignoring them. Now they only see it if they look for it. Their brains had been trained not to see them. Many people who worry about eye floaters have bad anxiety. This is the reason eye floaters are a problem for these people. They cannot get over it and ignore it because they are constantly worrying about it. Another example in how the brain plays a role in seeing. There was a famous study done awhile back with kittens. The kittens would be placed in a cylinder room with only veritcal lines for an extended period of time. After freeing them of this room, the cats were unable to see horizontal lines. It was completely invisible to their brains. The cats would literally walk into objcts which were horizontal. This goes to show you, that the brain is constantly changing and adapting to your needs. If you worry about eye floaters or look at them, the more your brain will rocognize them and make them visible to you. Your brain will develop neurons, synapses and connections. It works the other way around as well. if you try your hardest not to look at them and pay as little attention to them as possible, you wont notice them or rarely notice them. This is very hard to do though because you cannot test yourself for them or think about not thinking of them. It has to come naturally. Another thing to prove my theory is that since noticing my floaters I have been seeing a lot of entoptic phenomena (sparkles in the sky,grainy vision). I have also trained my brain to see this too. Everyone has this just like everyone has eye floaters to a certain degree. Anyone else here notice that the more you look at them the worse they get? keep in mind though that brain training isn't responsible for people who got their floaters because of injury, pvd, syneresis, etc. You do not have to have gone through any degredation to have eye floaters, they are in everyones eye, even infants. Anyone who has had a similar experience to me, the best thing you can do is try to reverse the process by not thinking of them no matter how hard it is, just look through them and eventually your brain will learn to ignore them. I'm just trying to help people save a lot worry and wasted time.
