The distance between the eye-lens and the retina is about 20 mm. When an object is very far away from the eye, the image is located essentially at the focal point. Therefore the focal length of the cornea and the eye-lens should be about 20 mm when the muscles of the eye are relaxed.Since the strength of a lens is the reciprocal of its focal length in meters, the strength of the cornea and the eye-lens in this situation is about 1/0.020 = 50 diopters.he distance between the eye-lens and the retina is about 20 mm.
