I have strange visual disturbance for couple of months now. Here is how I would describe it.
I get very quick afterimages after seeing certain Neon signs, bright screens or even patterns in certain light background. The afterimage (always negative) persist for < 1 second - it is like a spark of negative light.
Anyone experienced this ?
It does not impact my day to day life but definately is something wrong. Dark borders of wall clocks for example will give me afterimage for < 1 second when I look away.
Any clues ?
