I'm a 24 year old male, and for the past few years, I've been experiencing what I can only describe as blotchy vision. It's akin to static within my vision. For example, if I look at a white wall, I can tell its white, but I can see blotches of many other colors upon it, like multicolored static. I also feel like images persist on my retina longer than they should, so I experience "ghosting" if I look at something and then look away. In general, my eyes are also sensitive to light for this reason.
I recently had my eyes examined by an ophthalmologist and everything came out okay, including eye pressure, although I have a family history of glaucoma. I am in good general physical health.
What could this be?
