Expert Answer:

Dear student

Pls check at ur end there cud be an error in the units of qunatity of 0.5 cm..it cud have been 0.5 m.

 

In such case:

The eye is suffering from myopia.

For correction,

image requires to be formed at v= -0.5m

object at infinity (for objects like stars), u = - (infinity)

Uisng lens formula

1/f = 1/v -1/tituting for the value, f = - 0.5 m

 

Substituting for the value

f = - 0.5 m

Power of the corrective lens required

P = 1/f =- 1/0.5= -2D
