eli5, why does the red light on my tv seem to be affected by my eyelids in an abnormal way

Question

Title sounds stupid sorry, cant think of a better phrasing

So this happens with the lights on or off, the off light on my tv, if i squint even a tiny bit it shows on my view of the light, even though my eyelid/lashes arent anywhere near the light in my vision, yet i can still see this

I wish i could show what i mean but obviously, i cannot

i’m not sure if i understood it correctly but maybe you are talking about persistence of vision?

similar to when you watch the sun or a birght light and even if you stop watching it and close your eyes you can still see the circle?

or maybe you are talking about “rays” that comes from a light source?

similar to this effect: [https://i.pinimg.com/originals/1e/a9/13/1ea913eba1b059f511f7fcc58de833c2.jpg](https://i.pinimg.com/originals/1e/a9/13/1ea913eba1b059f511f7fcc58de833c2.jpg)

i guess that this happens because when you half close the eye you bend the “lens inside the eye”
