WebSep 12, 2024 · Writing the equation for power in terms of the focal lengths gives 1 f e y e = 1 f c o r n e a + 1 f l e n s = 1 2.3 c m + 1 6.4 c m. Hence, the focal length of the eye (cornea and lens together) is f e y e = 1.69 c m. The optical power of the eye is P e y e = 1 f e y e = 1 0.0169 m = 59 D. WebTo be precise, the formula for the focal length is: 1/f lens = (n glass - n incident) * (1/R 1 - 1/R 2), where R 1 and R 2 are the radii of curvature of the entrance and exit of the lens. For a lens in air n incident is close to one. For water it is 1.33 or so. For various types of …
