Web12. sep 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. WebReflection is the change of direction of a wave at an interface separating two different mediums so that the wave is redirected towards the medium in which it had been propagating. Refraction is the change of direction of a wave when it leaves a medium and enters another one.
