Question

the far point of a myopic person is 80cm in front of the eye what is the nature and power of the lens required to correct the problem​

Answer 1

Explanation:

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=−80 cm=−0.8 m

The power of the lens can be obtained as

P=  1/f

 = 1/-0.8

  = -1.25 D

Answer 2

Answer:

hey mate here is your answer......

Explanation:

☑️ For correction myophia, concave lens is required.

▶️ The image of a distant object should be formed at 80cm by concave lens.

➡️ u = -infinity , v = -80cm

➡️ By lens formula 1/f = 1/v - 1/u

➡️ ( 1/-80 ) - (1/ infinity) = -1/80

➡️ Power = 1/f = (-100/8)

➡️ -1.25 D

Hope it helps!☺️
