What is If the refractive power of the unaccommodated eye of an emmetropic woman is 60 diopters (D), the axial length of her eye is closest to? and explain in detail?
The focal point of an optical system (in meters) is the reciprocal of the refractive power of the system. Therefore, the focal point is 1/60 diopter (D), or 16.7 mm. An emmetropic eye forms a focused image of a distant object on the retina without accommodation. If the axial length is 16.5 mm, the image will be focused on the retina. Ref: Chang D.F. (2011).
