WebIn optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the radii of curvature of the lens … WebHence, the focal length of the eye (cornea and lens together) is. f eye = 1.69 cm. The optical power of the eye is. P eye = 1 f eye = 1 0.0169 m = 59 D. For clear vision, the image distance d i must equal the lens-to-retina distance. Normal vision is possible for objects at distances d o = 25 cm to infinity.
