Usually this is referred to as a floater. The medical term in Posterior Vitreous Detachment or PVD for short. This is different from a retinal detachment. PVD is when the vitreous jelly separates from the retinal wall causing visual distortion in the form of floaters or flashes of light. These pesky floaters usually subside or you just become adjusted to them. If you were ever to see Large floaters, a shower of floaters, Curtains coming down in your vision, spiderweb looking floaters or flashes of light like someone is taking your photo, this is considered a ocular emergency and you should be seen by a ophthalmologist immediately. I would still have a dilated exam with a ophthalmologist just to be on the safe side. Hope this helped.
They are called floaters and are caused by cracks in the gel inside your eyeballs. It is normal for old people.
This is called a pupil
This is the pupil.
A dark spot at the back of the eye may be a signal of melanoma, which can grow unnoticed within the retina. If it is caught early, melanoma can be treated before it can cause serious damage and travel to other areas of the body through the bloodstream. It would be a safe bet to have him visit his eye doctor with these concerns.

The small opening of the iris in the eye is the pupil.
This spot is where the optic nerve and blood vesicles enter the eye and it is called the "optic disc".

Their feathers are mostly brown, with white tips. Tail feathers are black and brown. Legs and feet are white. Often they have a spot of orange/red behind the eye. Eye colour is black. Beak colour is grey to black.
The blind spot is the part of the eye where the optic nerve leaves the eye. There are no light receptors so that is why it is called the blind spot.The spot is called the optic disc, or optic nerve head. Whatever part of your field of vision that falls upon this small spot will not be transmitted to the brain as part of the image. Fortunately for us, where two healthy eyes are functioning, the blind spot of each eye is compensated for by the other eye. There are quick and easy demonstrations of the blind spot that can be very dramatic for first-timers. What you 'perceive' at the blind spot is what the brain literally fills in. The spot seems to take on the general texture and color of whatever is around it. There is no perception of a 'black spot', or an empty space, since these would have to be detected visually.
The eye spot in plant like protists function as a sensory structure.

That is the planet Jupiter. The black spot was created recently when a asteroid collided with it. Jupiter has a Great Red Spot created through storms. No planet has a black spot no mars has a giant red spot and mercury has the black spot
