Wow im thinking I found the right forum.. So I used to see these spots a lot when I was younger. Now only see them 3 to 4 times per year.. ive read the posts in this thread and most if not all the details match what ive seen today.. the best way I can describe it would be burning ants.. im sure all of us have done this if not have a weird friend who enjoyed this past time. The moment before u catch sun light through the magnifying glass when it comes to a point with a little bit of a tail. Only I can see them when im in the house on more then one occasion.. I understand staring at the sky or sun directly can cause spots which only makes sense to me. But I have seen them in poorly lite situations.. im puzzled or are my eyes just that sensitive?
