Given data-

The separation of the glass from the eye is 1 cm

For the near-sighted person, u = ∞.

Looking into the fig. distance of the image from the lens, v

= Distance between image and eye − distance between the glass and the eye
= 25 − 1 = 24 cm = 0.24 m

Hence v=0.24m

Using lens formula –

Substituting the values-

Power of the lens,

Hence, lens of power − 4.2 D is required to see distant objects is
