Question

The image of an object formed by your eye lens on the retina is

Answer 1

Answer:

An image is formed on the retina with light rays converging most at the cornea and upon entering and exiting the lens. Rays from the top and bottom of the object are traced and produce an inverted real image on the retina.

Answer 2

Here object distance = -25 cm

Image distance (v) = distance of near point = -d

Let 'f' be the focal length of bi-convex lens.

Using lens formula,

$\frac{(1)}{f} = \frac{1}{v} - \frac{1}{u}$

$\frac{1}{f} = \frac{1}{ - d} - \frac{1}{ - 25}$

$\frac{1}{f} = - \frac{1}{d} + \frac{1}{25}$

$\frac{1}{f} = \frac{(d - 25)}{25d}$

$f = \frac{25d}{(d - 25)}$

( f is measured i centimetres

✈︎we know that if

$d > 25 \: cm$

then 'f' become +ve i.e., we need to use to use biconvex len to correct defect of hypermetropia.
