The human eye is often compared to a camera because it also has a system of lenses. These lenses are responsible for focusing the incoming light onto the retina, which is located at the back of the eye.

Option-1: This option suggests that the eye lens forms a straight or upright, real image of the object on the retina. However, this is not correct. In reality, the image formed on the retina is inverted or upside down.

Option-2: According to this option, the eye lens forms an inverted, virtual image of the object on the retina. Although the image is indeed inverted, it is a real image and not a virtual image. A virtual image would be formed when the light rays do not actually converge to a point but only appear to do so.

Option-3: The correct answer is option 3. The eye lens forms an inverted, real image of the object on the retina. This means that the image formed is upside down and can be captured on a screen or film.

Option-4: This option suggests that the eye lens forms a straight or upright, real image of the object on the iris. However, the iris is a part of the eye responsible for controlling the amount of light entering the eye, and it is not involved
