Visual Tracers

[Michael Jones]

I have a question regarding vision.  All my life I have seen tracers. 
This is where the refresh rate of my vision is slow and I see traces of 
objects behind them as they move.  I also occasionally see small 
explosions of light (looks like a non-moving falling star) in my 
peripheral vision or complex patterns.  These effects are all enhanced 
if I am tired.  I think this is a neurological phenomenon and I was 
wondering if anyone knows the official name of such visual anomalies.
