Back in my dim and distant past I have experience with (street) amphetamine sulpate. Visual disturbances decreased when the speed was active, and increased drastically during comedowns. Of course that was street stuff and not pharaceutical dexedrine which one would hope would be a little cleaner, but I think the effect was due to the amphetamine itself rather than any impurites.

This is my experience, too - the symptoms are reduced while it's active but increased after the comedown. My symptoms are relatively mild, so they weren't increased very much, but still. I think it might partly be also that I just don't get distracted by the visuals while I'm on Adderall (that's what I was taking).
