p=3.0D contact lens is needed to correct his distant vision.

The person is suffering from myopia and hence need a concave lens to correct the defect. The lens should be such that an object at infinity must form its image at the far point.

Hence,f= -32.3cm

= -0.323m

we can define the power of the lens as the reciprocal of its focal length in metre.

The power of lens is the ability to converge and diverge rays of light.

The power of the lens can be obtained as:

p= 1/f

p=1/(-0.323)

p=3.0D

Thus,the power is 3.0D to correct his distant vision.
