Few months ago i noticed a dark circle in my central vision that looks like a dark popcorn. It is only visible in dim light or if i look at something dark blue.
It changes size depending how far i see,and becomes more visible if i blink fast. I first noticed it when i installed blue rgb colors in my room and looked at the wall. I searched on the internet but i haven't found anyone with the same problem.
My eyesights are fine in normal light and my central vision is good too. i've attached a picture to show does the it looks like.
Thanks for your Question
This spot that is not moving with your eye should be examined by an eye doctor. There are many causes, some of them are transient and benign while other causes require treatment.
These are not an eye floaters, as eye floaters move with the eye.
