When they "turn on the spot" to apparate, it means that they literally turned in a circle, keeping their feet in the same general spot on the ground.

The thrush overheard the conversation that Bilbo had with the dragon about the spot.
At the small spot in each eye where the optic nerve exits the eye, they are no light receptors and therefore no vision. The blind spots are to the outer sides of the field of vision and therefore less critical than if they were close to the center. Also, the blind spot in each eye is compensated for by the other eye for those who have two intact eyes.
The "blind spot" is the point at which the optic nerve leaves the eye. Think of it as a cable attached to the back of the eye, carrying all your visual information to the brain. As a result, there are no receptors at the "blind spot".
The blind spot on the retina lacks light-sensitive cells (rods and cones), causing it to be unable to detect light and form images. This creates an area where the brain doesn't receive visual information, making it a literal "blind spot" in our field of vision.
The brain compensates for the blind spot. It compensates for it by taking in what is around the blind spot and using that as a reference to put a picture in the brain of what it thinks should be in the blind spot.
A blind spot is an area in the visual field that lacks visibility. In the eye, it is where the optic nerve exits and no light receptor cells are present. When driving, blind spots are areas around a vehicle where the driver's view is obstructed, requiring extra caution.

If light rays are focused directly on the blind spot in the eye, those particular light rays would not be detected by the retina because the blind spot is the area on the retina where the optic nerve exits and there are no light-sensitive cells present. This would result in a gap in the visual field where those light rays are not perceived.
It's a phenomenon when the eyes see what the mind believes. Evidently, "scoptoma" is a misuse of the word "scotoma," a word used in medicine for a condition that causes visual blind spots, and in psychology to describe a mental blind spot -- the inability to understand or perceive some matters. There is no linguistic authority, such as a reputable dictionary, medical or otherwise, that identifies or defines the word "scoptoma."
The blind spot is the point on the retina where there are no receivers i.e. no cones or rods, and the reason there are no cones or rods is because this spot is where the opic nerve teminates in the retina. No receivers, no signal to the brain.
the blind spot does not effect your vision, sort of... you see, your brain uses all the information from the picture/its vision to fill in that blind spot, in other words what you think your seeing is really not true (in your blind spot) your brain is putting what it thinks should be there.
Get out of their blind spot...
The blind spot in the eye is located where the optic nerve exits the retina. This area lacks light-sensitive cells (rods and cones) that are essential for vision. Despite this blind spot, the brain fills in the missing information from the surrounding areas to create a seamless visual experience.
