Self injury is hard to stop and it is hard to judge someone else's way of SI'ing if this is what staring at the sun is classified as.

But to me there is a huge difference in long term consequence of staring at the sun as opposed to cutting - one leaves scars on the skin, the other potentially scars on the back of the eye - I am no eye expert, but I think you may be putting your vision at risk if you continue this way of dealing with things.

I guess there's 2 things you could do:

1. Get some therapy to get to the root of why you do this
2. See an optician / doctor to see what those black spots are.

Well done for sharing this by the way and take care - SD
