Answer :
Final answer:
To correct myopia, a diverging lens is used. The power of the lens can be calculated using the formula Power = 1 / focal length. The correct power in this case is 0.66 D.
Explanation:
To correct the defect of myopia, a diverging lens is used. The power of the lens can be found using the formula:
Power (in diopters) = 1 / focal length (in meters)
Given that the far point of the myopia lens is 1.5 m, we can find the power of the lens:
Power = 1 / 1.5 = 0.67 D
Therefore, the correct option is (a) 0.66 D.
