Weird Vision for 7 months?

For the last 7 months I've been having weird vision. I see:

-White moving specks 24/7 when i look up in the sky

-After images

-Black lines almost looks like the veins inside my eyes. (This only shows when I exercise) This symptom freaks me out the MOST

So I have no idea whats wrong with me. Been to an eye doctor (clear)

I've even had a brain MRI (clear)

So I don't know if this is normal. If I have a vitamin deficiency.

Anyone knows what it could be or has experienced something like this it would be great to hear from you. Should I be worried?

Hi, yes i have the exact same problem.  I had retina tares 15 years ago that were sealed and since then i have these exact symptoms.  I dont think its a vitamin problem its more to do with the vitrose jelly around the retina not being stable from what i understand.  It might be worth having your eye examined again to check for tares ?  Let me know what happens

Sorry meant to ask youou live in the UK ?

grrrr try again, meant to ask your age and if you live in the UK?

Look up PVD eye

The vein like symptom i was told is a type of eye phenomenon. The white dots sound like a type of floaters made of white blood cells.
