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.
Pupil. The visible black center of the eye is the pupil. The pupil works like the aperture or opening of a camera to regulate the amount of light entering the eye. In bright light, the pupil closes down to limit how much light comes into the eye. In dim light the pupil opens up and becomes visibly larger. This allows the eye to receive more light.
