why isit difficult to see the details of images that are formed at the edge of the retina
Retina
behind the retina
Retina is a part of eye where images of objects are formed.
Images are formed on both of them.
The image should form on the retina. More specifically in the fovea centralis of the macula of the retina.
It is right that the retina forms the images the written way. I think it is because the various images formed are converted into electrical signals whoch are sent to the brain. The brain then interprets the correct position and form of images.
The short answer is that the interpretation of what you see occurs in the visual cortex, not in the retina.
Virtual images can't be captured anywhere. The imagescaptured on the retina are real ones.
For people who are farsighted, images come into focus behind the retina; for people who are nearsighted, images come into focus in front of the retina.
The center region of the retina is called the macula. this is where images are focused.
