Can straining your eyes to focus cause vitreous floaters?

I'm a 24-year-old male. I posted a question on here not long ago about vitreous floaters. My situation is quite complex, but I'll try to explain. I suffer from obsessive-compulsive disorder (OCD). I have a particularly bad obsession with proofreading things to the point where I have to look at every individual letter of a word. I often have to strain my eyes in order to do this. Is it possible that eye strain can cause vitreous floaters? I gather that the general consensus is no. I've tried to think about this. Straining your eyes to focus would mean putting stress on the ciliary muscle that changes the shape of the lens, right? Could this muscle being pushed to the extreme, and therefore the lens being pushed to the extreme, somehow cause vitreous floaters? I go through absolute hell with my OCD, as I know many others do, and I'm now worried that this crippling mental illness may have caused these vitreous floaters. Thanks for your replies.
