The dot disappeared
Distance from right eye to screen / cm
Distance from left eye to screen / cm
Why does the dot disappear at that distance?
The lens cannot focus light on that part of the retina
The eyelid shades that part of the eye
The dot is too small to see at that distance
The optic nerve leaves the eye there, so there are no rods or cones to detect light
