The images formed on the retina are inverted and reversed, meaning they appear upside down and backwards compared to their actual orientation in the external environment. This occurs because of the lens's refractive properties, which bend light rays to focus them on the retina. The brain then processes and interprets these inverted images, allowing us to perceive the world right-side up.
why isit difficult to see the details of images that are formed at the edge of the retina
Retina is a part of eye where images of objects are formed.
In the human eye, images are formed on the retina, which is a light-sensitive layer located at the back of the eye. The lens of the eye helps focus light onto the retina, where it is converted into electrical signals that are sent to the brain for processing.
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.
In farsighted individuals, images are formed behind the retina due to a shorter-than-normal eyeball. This can lead to difficulty seeing close-up objects clearly, as light entering the eye focuses on a point beyond the retina. Glasses or contact lenses can help correct this by refocusing the light onto the retina.
The short answer is that the interpretation of what you see occurs in the visual cortex, not in the retina.
Virtual images are produced by rays of light that appear to converge at a specific point behind the retina. When these rays enter the eye, they are refracted by the cornea and lens in such a way that they appear to intersect at a point in front of the retina. This results in an inverted and smaller image being formed on the retina, which the brain then interprets as a virtual image.
You see objects because they reflect light rays. As light travels to your eyes, the lens focuses the image of the object on the retina. The image of the object in the retina is inverted. As the image is formed, the optic nerves send the message to the brain. It is the brain that interprets and corrects the inverted image into an upright position. - Science Links by Sugpatan, Parde and Apolinario
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.
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 center region of the retina is called the macula. this is where images are focused.
