Reply to comment by DatsunL6 in Does the central part of my vision see in a different frame rate than the outer part? by Calvinkelly

Not quite true. The true blind-spot is a little off-axis from the centre of vision.

What you describe is the effect that dimmer stars may seem to "disappear" when you look straight at them because the centre of vision, the fovea (while having higher resolution and colour) is less light-sensitive.

That's right. Dimmer stars disappear when directly looked at and it's not to do with the blind spot.

Any star I look at, bright or dim, disappears when I look at it because I have macular degeneration.
