Black eye

The last couple of days, since Friday it was black: Black on one eye.
The doctor covered my eye with a patch in order to protect it and to prevent it from blinking.
Every blink was like sandpaper scratching in my eye.
Somehow a sand grain or something else had jumped in my eye and scratched the surface.
It was extremely painful, so the best thing was to put a bandage on the eye and some salve to heal it.
I am thankful to say that it  is going a bit better now.
