Vedclass · Answer

(A) In figure $1$,parallel rays from infinity focus before the retina,which is the condition for myopia (short-sightedness). Therefore,the statement '$1$ represents far-sightedness' is incorrect.In figure $2$,a concave lens is used to correct myopia (short-sightedness).In figure $3$,parallel rays focus behind the retina,which is the condition for hypermetropia (far-sightedness).In figure $4$,a convex lens is used to correct hypermetropia (far-sightedness).Thus,option $A$ is the wrong description.

$(I)$ Presbyopia	$(A)$ Sphero-cylindrical lens
$(II)$ Hypermetropia	$(B)$ Convex lens of proper power may be used close to the eye
$(III)$ Astigmatism	$(C)$ Concave lens of suitable focal length
$(IV)$ Myopia	$(D)$ Bifocal lens of suitable focal length

Identify the wrong description of the above figures.
