What part of the eye should image fall to see clear object?

For an object to be seen clearly, the image formed by the eye should fall on the retina. The retina is a thin layer of tissue that lines the back of the eye and contains photoreceptor cells called rods and cones. These cells convert light into electrical signals that are then sent to the brain. When the image of an object falls on the retina, the rods and cones detect the light and send the signals to the brain, which interprets them as a visual image.
