Why do I see a flashing light only when I'm watching?

I'm lying in the dark room in front of me is my laptop he is in standby mode and then always flashes with a white little light. Why do I see the light only when I look next to the laptop but when I look where the light is actually I see nothing? I always see it in the corner of my eye…

Maybe someone has an idea and can answer the question.

Should not be like that normally.

So I see such lights even if I look directly.

However, I have the effect, when it is almost completely dark, I see moving things (cat for example) from the corner of my eye better than when I look directly at it.

Yes, you can see better in the dark somehow from the corner of your eye. I think it's because of the different suppositories on the retina, otherwise I can't explain that. Obs true I do not know.

I know this effect of very fast flashing lights (many LEDs), you only see that when you move your head back and forth, but not with slow flashing lights.
