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 difference in available light from the larger exit pupil is significant. The larger the exit pupil, the less critical the position of your head in relation to the scope is, also. The distance that your eye must be to the ocular lens to get a full, clear picture is called eye relief.
