Question

the far point of a myopic person is 2 metre in the front of the eye what is the nature and power of lens required to correct the vision​

Answer 1

Hey Dear,

◆ Answer -

Concave lens of -0.5 D

◆ Explanation -

Myopic person needs concave lens to correct the refractive error.

To calculate far point of vision,

u = -∞

v = -2 m

Power of concave lens is calculated as -

P = 1/v + 1/u

P = 1/-2 + 1/-∞

P = -0.5 D

Therefore, the myopic person requires a concave lens of power -0.5 D to correct his vision.

Best luck dear...
