What is the optical power of glasses with a concave lens if the focal length is 50cm?
| September 20, 2021 | education
Data: F (focal length) = 50cm = 0.5m.
Optical power (take into account that the lens is concave (scattering)): D = -1 / F = -1 / 0.5 = -2 diopters.
Answer: The value of the optical power of the glasses, according to the calculation, is -2 diopters.
