It actually depends on the lens. For the image to be sharp on the retina, all the rays of light coming off the object must meet together at the same point on the retina. If the rays of light meet somewhere in front of the retina, the lens focuses by stretching itself and becoming thinner. This spreads out the rays of light, making them go further into the eye until they reach the middle of the retina. If the rays of light are behind the retina, the lens thickens to focus.
Fovea centralis - The central area designated the fovea produces the sharpest vision. It has the highest density of cone photoreceptors, which provides the highest resolution.

That is called as fovea centralis. This is situated on the retina.
The Fovea
Myopia
The retina
The CCD (in a digital camera) or film. They act as the surface the image is projected on as in the retina of the eye.
The blind spot or optic disc
The retina.
A common way of correcting this problem is the use of corrective lenses in glasses or contact lenses
When the image focuses (falls) behind the retina
The retina is where the image is formed.
Without the lens in your eye you can not form a image on the retina. As the retina is kept at a fixed distance you change the thickness of the lens to get the image on the retina.
for 1/16th of a second an image persist on retina of human eye

On the retina.
When the image hits the retina, it is upside down but our brain automatically converts it so it is flipped to become an upright image.
The cornea and lens of the eye form a real, inverted image on the retina.
The image of an object formed on the retina of the human eye is called Image Formation. Image Formation is the natural processing of light through the eye.
the iris and the lens focus the image to fall on the RETINA.
