Just happened to my older sister.

I started seeing “shooting stars” out on the far edges of my vision 2 years ago and went into the eye doctor. She took super high res pictures and said so far mine was pulling loose gently, but that if I started seeing large numbers of new “floaters” suddenly head to the ER as soon as possible.

With my sister she went from seeing extra new floaters to no vision in that eye within 3 hours.

If you are over age 57 sometime in the next few years this attachment of the back of “the white of your eye” to the area around the rods and cones is going to either come loose slow and gently without damage,
or too quickly so that there is bleeding.
