The optical power of the glasses is 2.4 and 1.24 diopters, respectively. What is the focal length of each lens?

The optical power of the lenses of the glasses can be calculated using the formula:
D = 1 / F, where D is the optical power of the lens of the glasses (diopters), F is the focal length of the lens (m).
D1 = 2.4 diopters, D2 = 1.24 diopters ..
Let’s calculate the focal lengths of the lenses:
F1 = 1 / D1 = 1 / 2.4 = 0.417 m.
F2 = 1 / D2 = 1 / 1.24 = 0.806 m.
Answer: The optical power of the lenses of the glasses is equal to 0.417 m and 0.806 m.
