It's size will be proportional to the amount it is filling your vision. If you can see nothing else, it will fill your retina. If, however, the object is only 1% of what you can see, it will only cover 1% of your retina.
The inner rear surface of the eye which contains photoreceptors it called the retina.
Retina- light image is focused on the retina, and it contains the photosensitive receptor cells Pupil- the opening of the eye. The size of the opening is regulated by the iris Iris- pigmented part of the eye (gives people their eye color). The iris is composed of smooth muscle and controlled by reflex.
The retina
The short answer is that the interpretation of what you see occurs in the visual cortex, not in the retina.

the retina contains the rods and cones which sense the amount of light and different colors respectively.

The retina. This consists of layers of cells that detect light and colour and transmit information to the brain via the optic nerve.
It's size will be proportional to the amount it is filling your vision. If you can see nothing else, it will fill your retina. If, however, the object is only 1% of what you can see, it will only cover 1% of your retina.
The retina is part of the eye
the layer that supplies blood to the retina is the "Sclera" which is the outermost layer of the eye.
