Green Afterimages?

[Narin_inar]

Hi,
I accidentally flashed a laser beam into my eyes about 2 years ago.
The color of the beam was purple. I remember playing with it and
flashing it for about 25-30 seconds on my eye. After that I could see
everything, but in GREEN. I tried to rinse my eyes with water. Nothing worked and
I was afraid. So after 20 mins of me shutting my eyes I could see everything normally.
I visited a doctor and she said there was no problem.

But now, whenever I see a purple color object, image or anything purple and intense
there are afterimages of it in green color. They last for about 3 seconds, sometimes even longer (8-10 sec) if I
keep starring at it. I didn't tell my doctor about it as I discovered it after the visit.
Have I damaged anything? I like to look at those pinkish-purple flowers in the garden, but the green afterimages
keep bothering me.

Is there any term that describes this condition? Is it a form of visual impairment?

Thanks!

Thanks you. Is there any specific term which describes this retinal damage?
