Question

What happens to the image distance from the eye lens in the normal eye when we increase the distance of an object from the eye?

Answer 1

Hint – To see closer or distant objects clearly, the eyes, due to its ability of accommodation, can increase or decrease the focal length of its lens, so that image is always formed at the retina.

Complete step-by-step solution -
The image is formed only on the retina even if the distance of an object increases from the eye. To see closer or distant objects clearly, our eyes have the ability of accommodation, i.e. the eyes can increase or decrease the focal length of its lens so that the image is always formed on the retina of our eye.
So, there is no change to the image distance in the eye even if we increase the distance of an object.
Also, to know how the image formation takes place in our eyes, it is discussed below-
First of all, light enters our eye through the transparent cornea and passes through the aqueous humor, the lens, and the vitreous humor, and here it finally forms an image on the retina of our eye. This image is virtual and erect. Our eye forms a virtual image of the real object but this image is of the same size as the object.

Note – Whenever such types of questions appear then keep in mind that the image is formed on the retina of our eyes so changing the distance of an object either increasing or decreasing will not have any effect.
