Diffraction limite of the human eye. oldspice1212. Calculate the diffraction limit of the human eye, assuming a wide-open pupil so that your eye acts like a lens with diameter 0.8 centimeter, for visible light of 500-nanometer wavelength. Is there a formula for this? There are two other parts to this question, but if I get this the others won't be hard to get.
The young human eye can change focus from distance (infinity) to 6.7 cm from the eye in 350 milliseconds. This dramatic change in focal power of the eye of approximately 15 dioptres (the reciprocal of focal length in metres) occurs as a consequence of a reduction in zonular tension induced by ciliary muscle contraction. The amplitude of accommodation declines with age.
