I have been getting a black speck moving about in my eye ( I notice it mainly in class when looking at the white board ). I have looked about on the internet and it seems to match the description of a floater. I have read that they are harmless and common in older adults but nothing really about them in children or teenagers.

Because I have gotten one so soon is there a chance that I may end up with loads of them by the time I'm 40/50 or does it not work like that and it is just me being stupid ?
