Question

A myopic person uses specs of power -1.6 D. What is the distance of far point of his eye.​

Answer 1

Answer:

Explanation:

if a person is suffering from myopia .. his far point is less than infinty.. as the image is formed in front of retina.

power of the spects = -1.6 D

we have,

P = 1/ F

-1.5 = 1/ F

F = -1/ 1.5

F = -10/ 15

THEREFORE, F = -0.67

this states that his focal length is -0.67m .
