Hey sometimes your eyes go through changes as you get older. The vitreous humor (the gelatinous part that makes up most of your eyeball) can get what are called "floaters" in it which are basically parts that have congealed and can affect your vision sometimes. For a while a had like a "squiggle" (like a blurry squiggly line) in my left eye.

So it's not necessarily the drugs..

But then again.
