This happened about 3 yrs ago while playing soccer at a futsal pitch. Opponent had kicked the ball to my face and i suspected that the small black beads has entered my left eye. There was a tear at first and I had to put on sunglasses for a week to prevent direct exposure to sunlight and lights. I just applied eyedrops for one week and it became better. Recently, on and off, I will have migranes and blurred vision of the left eye and at times it pains when I wake up lying on the left side.
